Refer to the exhibits. A web client sends a POST request to the HTTP Listener and the Validation component in the Try scope throws an error.
What response message is returned to the web client?
A . Validation Error
B . "END"
C . "ERROR1"
D . ''ERROR2"
Refer to the exhibits. The main flow contains an HTTP Request in the middle of the flow. The HTTP Listeners and HTTP Request use default configurations.
A web client submits a request to the main flow's HTTP Listener that includes query parameters for the pedigree of the piano.
What values are accessible to the Logger component at the end of the main flow?
In this case as outbound call is made using HTTP: POST /child , all attributes will be replaced by this invocation. Hence query parameter will not be accessible at logger. Hence correct answer is option 2
Refer to the exhibit.
How should be the where clause written for the configured input parameters in such a way that it achieves below SQL query?
Correct syntax to use where clause isWHERE city = :city AND state = :state
This question validates knowledge on using dynamic queries in DBselect operation.
Configure Dynamic Queries in the Select Operation
When you need to parameterize not only theWHEREclause but also parts of the query itself (for example, queries that compare tables that depend on a condition, or complex queries for which the project table columns need to vary), you can configure dynamic queries.
In the following example, you configure a dynamic query by using a full expression with a string in which the table depends on a variable$(vars.table). Although some of the query text is dynamic ('SELECT * FROM $(vars.table)), theWHEREclause still defines theWHEREcondition using input parameters: in this case,WHERE name = :name.
In your Studio flow, select theSelectoperation.
In the operation configuration screen, set theSQL Query Textfield toSELECT * FROM $(vars.table) WHERE name = :name.
Set theInput Parametersfield to{'name' : payload}.
The following screenshot shows the configuration in Studio:
Figure 3. Dynamic query configuration
In the XML editor, the<db:sql>configuration looks like this:
<set-variable variableName='table' value='PLANET'/>
<db:select config-ref='dbConfig'>
<db:sql>#['SELECT * FROM $(vars.table) WHERE name = :name']</db:sql>
<db:input-parameters>
#[{'name' : payload}]
</db:input-parameters>
</db:select>
You can apply input parameters only to parameters in aWHEREclause. To modify any other part of the query, use the DataWeave interpolation operator.

Refer to exhibits.
What message should be added to Logger component so that logger prints "The city is Pune" (Double quote should not be part of logged message)?
Correct answer is The city is #[payload.City]
Answer can get confused with the option #['The city is' ++ payload.City] But note that this option will not print the space between is and city name. This will print The city isPune
