Which tool do you use to create a calculation view in a multi-target application? Please choose the correct answer.
SAP Web IDE for SAP HANA
SAP HANA database explorer
SAP HANA Web-based Development Workbench
SAP HANA studio
To create a calculation view in a multi-target application, you need to use the SAP Web IDE for SAP HANA, which is a web-based development environment that supports the full development lifecycle of SAP HANA applications. The SAP Web IDE for SAP HANA provides graphical and code-based editors for creating calculation views, as well as other database artifacts, such as tables, views, procedures, functions, and more. You can also use the SAP Web IDE for SAP HANA to create and deploy multi-target applications, which are modular applications that consist of multiple components, such as database modules, Node.js modules, Java modules, HTML5 modules, etc. The other options are incorrect because the SAP HANA database explorer, the SAP HANA Web-based Development Workbench, and the SAP HANA studio do not support the creation of calculation views in a multi-target application. The SAP HANA database explorer is a web-based tool that allows you to browse, manage, and query SAP HANA databases, but not to create or edit database artifacts. The SAP HANA Web-based Development Workbench is a deprecated tool that was used to create and edit SAP HANA XS classic applications, but not multi-target applications. The SAP HANA studio is a desktop tool that was used to create and edit SAP HANA native applications, but not multi-target applications. References:
A Node.js module is executed for the first time in SAP HANA extended application services, advanced model (XS advanced). Which of the following activities are performed automatically? There are 2 correct answers to this question.
The source code is compiled to create an executable binary file.
A new SAP HANA Deployment Infrastructure (HDI) container is created.

You create a simple data model to store user information. The model contains two tables: one for the user information, and the other for user address details.
The user can only have one address. You also need a view to show the complete information of the user including the address.
Which actions do you perform if you use CDS artifacts only? Please choose the correct answer.
Create two entities for the user and address.
Create an association in the user entity to the address entity.
Define a User Details view using select on the address entity and using the association to read the user information.
Create two entities for the user and address.
Create an association in the user entity to the address entity.
Define a User Details view using select on the user entity and using the association to read the address information.
Create two entities for the user and address.
Extend the user entity with address columns.
Create a view named User Details using select on the user entity.
x-s Create two entities for the user and address.
Create a User Details calculation view and join the user and address information.
The correct action is to define a User Details view using select on the user entity and using the association to read the address information. This way, you can leverage the power of CDS associations to create a join between the user and address entities without explicitly specifying the join condition. You can also use the association path to access the address fields in the view definition. This approach simplifies the data model and avoids redundancy. Option A is incorrect because it selects from the address entity instead of the user entity, which is not the desired output. Option B is incorrect because it extends the user entity with address columns, which is unnecessary and violates the normalization principle. Option D is incorrect because it creates a calculation view instead of a CDS view, which is not the requirement. Calculation views are graphical or scripted views that can be used for complex calculations and data transformations, but they are not CDS artifacts. References:

In an SQL Script procedure, which feature do you use to initialize IN/OUT table parameters? Please choose the correct answer.
IS_EMPTY
DEFAULT EMPTY
DEFAULT
SET
According to the SAP HANA Developer Guide, you can use the DEFAULT EMPTY clause to initialize IN/OUT table parameters in an SQL Script procedure. This clause specifies that the table parameter is initially empty when the procedure is called, and that the caller can pass an empty table or no table at all. This is useful when you want to use the table parameter as a temporary table inside the procedure, and return the result to the caller. For example, PROCEDURE proc1 (IN/OUT tab1 TABLE(col1 INT, col2 VARCHAR(10)) DEFAULT EMPTY) ... The other options are incorrect, because:

What are the key characteristics of the calculation view's Input Parameter? There are 3 correct answers to this question.
It is passed using a WHERE clause.
It can NOT be used to filter measure values.
It can be used in a conditional expression.
It is passed via reserved word PLACEHOLDER.
It can be used to pass values to table functions.
A calculation view is a view that combines data from multiple sources, such as tables, views, or functions, using graphical or SQLScript logic. A calculation view can define input parameters, which are variables that allow the user to influence the query execution with values that are entered at runtime. Input parameters can be used for various purposes, such as filtering, currency conversion, or dynamic calculations.
Some of the key characteristics of the calculation view’s input parameter are:
inputparametername
” => ‘value’. For example, if the calculation view has an input parameter named CURRENCY, then the SQL statement to call the view with the value ‘USD’ would be SELECT * FROM “CALC_VIEW” (PLACEHOLDER.“
CURRENCY
” => ‘USD’).
The other options are incorrect because they are not characteristics of the calculation view’s input parameter. It is not passed using a WHERE clause, as the WHERE clause is used to filter data based on a condition, not to pass values to a view. It can be used to filter measure values, as measure values are numeric values that can be aggregated, such as sales amount or quantity. An input parameter can be used to filter measure values based on a range, a comparison, or a calculation. References:

You need to check user input data in your OData request. Which exit type do you use? Please choose the correct answer.
Consistency
Modification
Validation
Verification
To check user input data in your OData request, you need to use the Validation exit type. The Validation exit type is a custom exit that allows you to perform validation of input data and data consistency checks before, after, or during the change operation, or before or after the commit operation. You can specify a maximum of four validation exits per change operation; the exit is registered for the corresponding event with the respective keyword: “before”, “after”, “precommit” or “postcommit”. The validation exit is executed as an SQLScript procedure with a specific signature, and it can raise an error if the input data does not meet the validation criteria1.
The other options, Consistency, Modification, and Verification, are not exit types that you can use to check user input data in your OData request. Consistency is not an exit type, but a property that you can set in the OData service definition to enable or disable the consistency check for the change operations. The consistency check ensures that the data in the database is consistent with the data in the request payload2. Modification is an exit type that allows you to define custom logic to create, update, or delete an entry in an entity set. If a modification exit is specified, it is executed instead of the generic actions provided by the OData infrastructure1. Verification is not an exit type, but a process that you can perform to ensure that the OData service definition is valid and can be activated without errors3.

Why do you use associations in your persistence model for SAP HANA extended application services, advanced model (XS advanced)? Please choose the correct answer.
To enforce database-level constraints
To define the relationships between contexts and views
To define multiplicity and key of an entity relation
To set relationships between multiple contexts
Associations are used in the persistence model for SAP HANA extended application services, advanced model (XS advanced) to define the multiplicity and key of an entity relation. An entity relation is a logical connection between two entities, such as one-to-one, one-to-many, or many-to-many. Multiplicity specifies how many instances of one entity can be related to one instance of another entity. Key specifies which attributes of the related entities are used to identify and join the instances. Associations are defined using the Core Data Services (CDS) language, which is a declarative language for modeling data structures and services. Associations are part of the CDS entity definition, and they can be used to navigate from one entity to another, and to filter, aggregate, or project data from the target entity12.
The other options are not correct because they are not the purposes of using associations in the persistence model for XS advanced. Associations do not enforce database-level constraints, such as primary keys, foreign keys, or check constraints. These constraints are defined separately using the CDS annotations or the SQL DDL statements. Associations do not define the relationships between contexts and views, which are different types of CDS artifacts. A context is a namespace for grouping related CDS artifacts, such as entities, views, types, or associations. A view is a CDS artifact that defines a data model based on one or more entities or other views, and applies filters, joins, aggregations, or other operations on the data. Associations do not set relationships between multiple contexts, which are independent from each other and do not have any logical connection. References:

SAP HANA calculation views are flexible information views that you can use to define more advanced slices on the data available in the SAP HANA database. Calculation views can be created using graphical or script-based editors, and can include any combination of tables, column views, attribute views, analytic views, and other calculation views. Calculation views can also support complex expressions, multidimensional analysis, currency conversion, hierarchies, and other analytic capabilities. Some general characteristics of calculation views are:
The other options are incorrect because calculation views do not need an application server to execute, nor do they not need database tables to execute. These are the opposite of the correct characteristics of calculation views. References:

What happens if you define a database object in the persistence model and deploying using the SAP HANA Deployment Infrastructure
(HDI)?
Please choose the correct answer.
A descriptive representation of the object is created in Hot during runtime.
The corresponding runtime object is created in the database module of the multi-target application during runtime.
The HDI container is created when the design-time object is saved.
The corresponding runtime object is created in the HDI container on deployment
According to the SAP HANA Developer Guide, the SAP HANA Deployment Infrastructure (HDI) uses so-called containers to store design-time artifacts and the corresponding deployed run-time (catalog) objects. The HDI makes a strict separation between design-time and run-time objects by introducing the following, distinct container types:
When you define a database object in the persistence model, you create a design-time artifact in the DTC. When you deploy the database module of the MTA, the HDI creates an RTC and a BTC, and builds the corresponding run-time object in the RTC based on the design-time artifact. The BTC is then dropped, and the RTC remains as the HDI container for the database module. References: SAP HANA Developer Guide, Chapter 6, Section 6.4.2, page 2111.
What statement must you insert to the following OData service to complete the navigation definition from the customer entity set to the corresponding sales orders? Please choose the correct answer.
service{ "sample.odata::customer" as customer" navigates ("Customer_Orders* as "toOrders); "sample.odata::salesorder" as "Orders";)
Aggregation
Association
Key specification
Join condition
To complete the navigation definition from the customer entity set to the corresponding sales orders, you need to insert an association statement between the two entity sets. An association defines a relationship between two entity sets based on a referential constraint, which specifies the foreign key and the principal key properties that link the entity sets. An association also defines the cardinality and the role names of the entity sets involved in the relationship1. In this case, the association statement should look something like this:
association Customer_Orders with referential constraint principal customer key CustomerID dependent Orders key CustomerID multiplicity “1” to “*”;
This statement defines an association named Customer_Orders that relates the customer entity set with the Orders entity set based on the CustomerID property. The principal role is assigned to the customer entity set, which means that each customer entity can have zero or more related Orders entities. The dependent role is assigned to the Orders entity set, which means that each Orders entity must have exactly one related customer entity2.

You need to manage an exception in a SQLScript. Which SQLScript features can you use? There are 2 correct answers to this question.
DECLARE EXIT HANDLER
SIGNAL
DEFINE RESIGNAL
CREATE EXIT HANDLER
To manage an exception in a SQLScript, you can use the SIGNAL and RESIGNAL features, which are SQLScript statements that allow you to raise and handle errors or warnings in your code. The SIGNAL statement allows you to raise a user-defined exception with a specified message and SQLSTATE value. The RESIGNAL statement allows you to propagate an existing exception to the calling procedure or function, or to modify the message or SQLSTATE value of the exception. You can use the SIGNAL and RESIGNAL statements in combination with the BEGIN and END blocks, and the DECLARE and EXIT HANDLER clauses, to define the scope and the action of the exception handling12.
The other options are not correct because they are not SQLScript features that can be used to manage an exception. The DECLARE EXIT HANDLER clause is a SQL feature that allows you to declare a handler for a specific condition or a generic SQLWARNING, SQLEXCEPTION, or NOT FOUND condition. The CREATE EXIT HANDLER statement is not a valid SQL or SQLScript statement at all. References:
Which parameter do you adapt to change the file that is initially delivered by an HTML5 module? Please choose the correct answer.
Service_url parameter of the mta.xml file
Welcome file parameter of the xs-app.json file
Start parameter of the package.json file
Runners parameter of the projectjson file
An HTML5 module is a module that contains static web content, such as HTML, CSS, JavaScript, or images, that are delivered by a web server. An HTML5 module can be part of a multi-target application (MTA) project, which is a single application that consists of multiple modules that are developed using different technologies and designed to run on different target runtime environments. An HTML5 module can be deployed to the XS Advanced runtime environment, which is a platform that supports the development and execution of cloud-native applications on SAP HANA.
To change the file that is initially delivered by an HTML5 module, you need to adapt the welcome file parameter of the xs-app.json file. The xs-app.json file is a configuration file that defines the routing rules and authentication settings for the HTML5 module. The welcome file parameter specifies the name of the file that is served as the default document when the root path of the HTML5 module is requested. For example, if the welcome file parameter is set to “index.html”, then the file index.html in the HTML5 module will be delivered when the user accesses the URL of the HTML5 module without any additional path. The welcome file parameter can be changed to any valid file name that exists in the HTML5 module.
The other options are incorrect because they are not parameters that can be used to change the file that is initially delivered by an HTML5 module. The service_url parameter of the mta.xml file is a parameter that defines the URL of a service that is required by a module or provided by a resource in an MTA project. The start parameter of the package.json file is a parameter that defines the script that is executed when the npm start command is run in a Node.js module. The runners parameter of the project.json file is a parameter that defines the configuration of the runners that are used to execute the code in a Cloud Foundry module. References:
You are asked to produce sales value for the month using sales order line items (sales price per item x quantity sold) what do you use to achieve this in a calculated column of a calculation view? There are 2 correct answers to this question.
Keep flag
Dynamic join
Transparent filter
Non-equijoin
To produce sales value for the month using sales order line items (sales price per item x quantity sold), you can use a calculated column of a calculation view that performs the multiplication of the two columns and applies a transparent filter and a non-equijoin to restrict the data to the desired month. A transparent filter is a filter condition that is applied to the data source of a view node and is propagated to the subsequent nodes. A non-equijoin is a join condition that uses operators other than equality, such as greater than, less than, or between. For example, you can use a transparent filter to filter the sales order line items by the month of the order date, and then use a non-equijoin to join the sales order line items with the sales price table by the order date and the valid from and valid to dates of the sales price. References: Transparent Filters, Non-Equijoins, Create Calculated Columns.
Which rules apply to declarative logic in SQL Script? There are 2 correct answers to this question.
It supports the full set of SQL Script.
It defines how data is processed.
It is free of side effects.
lt declares the flow of data.
According to the SAP HANA Developer Guide, declarative logic in SQL Script is a way of expressing complex data transformations by means of classical relational operators, such as selection, projection, join, aggregation, etc. Declarative logic does not specify how data is processed, but rather what the desired result is. The SAP HANA database has the freedom to optimize the data flow and execution plan, which may result in better performance. Declarative logic is free of side effects, meaning that it does not modify any data or state outside the scope of the statement. Declarative logic declares the flow of data, meaning that it binds new variables that are referenced elsewhere in the body of the procedure or function. The other options are incorrect, because:

In a calculation view, what are the different types of input mapping available in Table Function? There are 2 correct answers to this question.
Variable
Constant
Formula
Data Source Column
In a calculation view, the different types of input mapping available in Table Function are Constant and Data Source Column. Constant allows you to map a fixed value to the input parameter of the Table Function. Data Source Column allows you to map a column from another node or data source to the input parameter of the Table Function12.
The other two options, Variable and Formula, are not types of input mapping available in Table Function. Variable is a type of input mapping available in Calculation Scenario, which allows you to map a variable from the calculation view to the input parameter of the Calculation Scenario3. Formula is a type of input mapping available in Scripted Calculation View, which allows you to map a formula expression to the input parameter of the Scripted Calculation View4.

You need to edit a database procedure. You are concerned that the version of the database procedure file you have in your local Git repository may not be synchronized with the latest version in the remote Git repository, but at this time, you do NOT want to sync the file. You only want to see the commits applied to the file in the remote repository. Which command must you use?
Git stash
Git fetch
Git merge
Git pull
To see the commits applied to the file in the remote Git repository without syncing the file, you need to use the git fetch command. This command downloads the latest changes from the remote repository to your local repository, but does not merge them with your local branches. This way, you can inspect the differences between your local and remote files, and decide whether to merge them later or not. You can use the SAP Web IDE for SAP HANA or the command line to execute the git fetch command. The other options are incorrect because they either sync the file or do not download the changes from the remote repository. The git stash command saves your local changes to a temporary stash and reverts your working directory to the last commit. This command is useful when you want to switch branches or pull changes without committing your local changes, but it does not download the changes from the remote repository. The git merge command combines the changes from one branch into another branch. This command is useful when you want to sync your local branch with the remote branch, but it does not allow you to see the commits applied to the file before merging. The git pull command fetches and merges the changes from the remote repository into your local branch. This command is useful when you want to update your local branch with the latest changes from the remote branch, but it does not allow you to see the commits applied to the file before merging.

Which trace do you use to create a graphical representation of an individual SQL Statement? Please choose the correct answer.
Expensive statements trace
Performance trace
Plan trace
SQL trace
To create a graphical representation of an individual SQL statement, you can use the Plan trace. The Plan trace is a tool that allows you to generate and visualize the execution plan of an SQL statement, with estimated or actual performance information for each operator. The Plan trace can help you understand and analyze the query optimization and execution process, and identify potential performance bottlenecks or improvement opportunities12.
The other options, Expensive statements trace, Performance trace, and SQL trace, are not tools that can create a graphical representation of an individual SQL statement. The Expensive statements trace is a tool that records the SQL statements that exceed a certain threshold of resource consumption, such as CPU time, memory, or disk reads. The Expensive statements trace can help you identify the most resource-intensive queries in the system, but it does not provide a graphical view of the execution plan3. The Performance trace is a tool that records the performance statistics of the database operations, such as SQL statements, transactions, procedures, or triggers. The Performance trace can help you measure and compare the performance of different database operations, but it does not provide a graphical view of the execution plan either. The SQL trace is a tool that captures every SQL statement that enters the database at the session layer. The SQL trace can help you monitor and troubleshoot the SQL statements that are executed in the database, but it does not provide a graphical view of the execution plan either.

You want to exclusively use declarative logic in an SQL Script procedure. Which of the following operators can you use? There are 2 correct answers to this question.
COMM IT statement
IF condition
TABLE variable
MAP_REDUCE function
To exclusively use declarative logic in an SQL Script procedure, you can use TABLE variables and MAP_REDUCE functions. TABLE variables are variables that store intermediate results of SQL queries in a tabular format. You can use TABLE variables to define data transformations and data flows without using imperative statements or side effects1. MAP_REDUCE functions are functions that apply a map function to each row of a table and then aggregate the results using a reduce function. You can use MAP_REDUCE functions to implement complex algorithms and calculations in a declarative way2.
The other two options, COMMIT statement and IF condition, are not operators that can be used to exclusively use declarative logic in an SQL Script procedure. COMMIT statement is a statement that ends a transaction and makes all changes permanent in the database. You cannot use COMMIT statement in a declarative logic, as it is an imperative statement that has a side effect3. IF condition is a condition that executes a block of code based on a boolean expression. You cannot use IF condition in a declarative logic, as it is an imperative construct that introduces control flow4.
