NEW QUESTION # 104
Refer to the exhibits.
What DataWeave expression transforms the conductorIds array to the XML output?
Answer: D
Explanation:
Points toremember:
* XML must have a root element.
* XML only allows one root element
* To avoid multiple root issues, you must create a root element for the XML output, whenever we transform output
* When mapping array elements (JSON or JAVA) to XML, wrap the mapoperations in {(..)}
-{ } are defining the object
( ) are transforming each element in the array as a key/value pair
* The transformation to XML would fail if the above mentioned considerations were not taken into account.
* Thus the transformation scriptdeclares a root element as trains and wraps the data in "{( )}".
Whenever you see such type of question, always look out for root element followed by {( )} wrapping map.
I call this a "Wrap The Map" scenario. Hope it would help you remember !

NEW QUESTION # 108
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?
Answer: B
Explanation:
Correct syntax to use where clause is WHERE city = :city AND state = :state This question validates knowledge on using dynamicqueries 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 complexqueries 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). Althoughsome 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 configurationscreen, 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-variablevariableName="table"value="PLANET"/>
* <db:selectconfig-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.
