NEW QUESTION # 45
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 = attributes.city AND state = attributes.state
- C. WHERE city := ${city} AND state := ${state}
- D. WHERE city = :city AND state = :state
Answer: D
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.

- B. Account Type: #[vars.accountType]
- C. Account Type: #[flowVars.accountType]

Answer: B
Explanation:

If the name of your variable is myVar, you can access it like this: vars.myVar Hence correct answer is Account Type: #[vars.accountType]

fun myFunction(param1, param2, ...) = <code to execute>
The fun keyword starts the definition of a function.
myFunction is the name you define for the function.
Function names must be valid identifiers.
(param1, param2, ... , paramn) represents the parameters that your function accepts.
You can specify from zero to any number of parameters, separated by commas (,) and enclosed in parentheses.
The = sign marks the beginning of the code block to execute when the function is called.
<code to execute> represents the actual code that you define for your function.
