The Validation component in the private flow throws an error. What response message is returned to a client request to the main flow's HTTP Listener?

• A. Error - main flow
• B. Validation Error
• C. Success - main flow
• D. Error - private flow

Answer: A

Explanation:
Error in validation component will get processed by Processer level On Error Propagate block and then error will be rethrown which will get processed by flow level error handler which will set payload to "Error- main flow". Hence correct answer is Error - main flow
1) Request is received by HTTP listener
2) Try scope gets executed
3) The validator component in the Try scope creates an Error Object because the payload is not null.
4) The On Error Propagate handles the error. The payload is set to "Error - Try scope"
6) "Error - Try scope" is returned to the 'On Error Continue' block. Main flow execution stops. Payload is set to "Error - main flow"
7) "Error - main flow" is returned to the requestor in the body of the HTTP request. HTTP Status Code: 200

3. Default Error Handler catches and Propagates error
4. 'On Error Propogate' is 'RED IN RED OUT'. It Returns Status Code : 500 & #[error.description]
-------------------------------------------------------------------------------------------------------------------------- Correct answer is String is not blank. Because validation component will throw an error as payload is not blank.

NEW QUESTION # 99
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?

• A. WHERE city := city AND state := state
• B. WHERE city := ${city} AND state := ${state}
• C. WHERE city = :city AND state = :state
• D. WHERE city = attributes.city AND state = attributes.state

Answer: C

Explanation:
Correct syntax to use where clause is WHERE city = :city AND state = :state This question validates knowledge on using dynamic queries in DB select operation.
Configure Dynamic Queries in the Select Operation
When you need to parameterize not only the WHERE clause 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)), the WHERE clause still defines the WHERE condition using input parameters: in this case, WHERE name = :name.
In your Studio flow, select the Select operation.
In the operation configuration screen, set the SQL Query Text field to SELECT * FROM $(vars.table) WHERE name = :name.
Set the Input Parameters field 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 a WHERE clause. To modify any other part of the query, use the DataWeave interpolation operator.
