What is the correct syntax to define and call a function in Database?

Question # 44

Options:

Option A

Option B

Option C

Option D

Expert Solution

Answer

Explanation

Keyword to ad function in Dataweave transformation is fun. Hence option 2 and 4 are invalid. Also parameters needs to be passed exactly in same order as defined in function definition. Hence correct answer is'

fun addKV( object: Object, key: String, value: Any) =

object ++ {(key):(value)}

---

addKV ( {"hello': "world"}, "hola", "mundo" )

MuleSoft Documentation Reference : https://docs.mulesoft.com/mule-runtime/4.3/dataweave-functions

DataWeave FunctionDefinition Syntax

To define a function in DataWeave use the following syntax:

fun myFunction(param1, param2, ...) =

The fun keyword starts the definition of a function.

myFunction is the name you define for the function.

Function namesmust 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 thecode block to execute when the function is called.

represents the actual code that you define for your function.

						A shopping API contains a method to look up store details by department
To get information for a particular store, web clients will submit requests with a query parameter named department and a URIparameter named storeld.

					          		Lets revise few concepts RAML which can help us to find the answer of this question.
URI Parameters
Lets have a look at below example.
/foos:
/{id}:
/name/{name}:
Here, the braces { } around property names define URI parameters. They represent placeholders in each URI and donot reference root-level RAML file properties as we saw above in the baseUri declaration. The added lines represent the resources /foos/{id} and /foos/name/{name}.
Query Parameters
Now we'll define a way to query the foos collection using query parameters.Note that query parameters are defined using the same syntax that we used above for data types:
/foos:
get:
description:ListallFoosmatching query criteria,ifprovided;
otherwise list allFoos
queryParameters:
name?:string
ownerName?:string
Based on the above information , below is the only option which defines storeid as uri parameter and department as query parameter.
/{storeId}:
get:
queryParameter:
department:

						A mule project contains MySQL database dependency . The project is exported from Anypoint Studio so that it can be deployed to Cloudhub. What export options needs to be selected to create the smallest deployable archive that will successfully deploy to Cloudhub?
					
					
						Options:
												A. Select both the options 1) Attach project sources 2) Include project module and dependencies
												B. No need to select any of the below options 1) Attach project sources 2) Include project module and dependencies
												C. Select only below option 2) Include project module and dependencies

					         		Explanation
					        	
					        	
					          		You can choose Attach Project Sources to include metadata that Studio requires to reimport the deployable file as an open Mule project into your workspace. You must keep the Attach Project Sources option selected to be able to import the packaged JAR file back into a Studio workspace. But requirement here is to create smallest deployable archive that will successfully deploy to Cloudhub. Hence we can ignore this option.
We need to select Include project module and dependencies
As actual modules and external dependencies required to run the Mule application in a Mule runtime engine
Hence correct answer is
Select only below option 2) Include project module and dependencies

					          		Scatter-Gather Router
The Scatter-Gather component is arouting event processor that processes a Mule event through different parallel processing routes that contain different event processors. Each route receives a reference to the Mule event and executes a sequence of one or more event processors. Each of these routes uses a separate thread to execute the event processors, and the resulting Mule event can be either the same Mule event without modifications or a new Mule event with its own payload, attributes, and variables. The Scatter-Gather component then combines the Mule events returned by each processing route into a new Mule event that is passed to the next event processor only after every route completes successfully.
The Scatter-Gather component executes each route in parallel, not sequentially. Parallel execution of routes can greatly increase the efficiency of your Mule application and may provide more information than sequential processing.
