Name
If (String)
Syntax
If (Boolean condition, String thenValue, String elseValue)
Purpose
To evaluate a given condition and if true, return result of thenValue. Otherwise, to return the result of elseValue.
Description
Returns the value of ‘Then’ expression or ‘Else’ expression depending on the value of condition.
Return Type
String
Parameters
Condition [System.Boolean] – Condition that is evaluated
thenValue [System.String] – This Parameter’s value is returned if the result of ‘condition’ parameter is true.
elseValue [System.String] - This Parameter’s value is returned if the result of ‘condition’ parameter is false.
Example
We have a Customers dataset which we will use to evaluate and transform the Items field.
In this example we will use the Expression object to define the condition, and a Variables object to define a string thenValue and a string elseValue.
Where,
Condition: Items = “1”
thenValue = FirstItem
elseValue = SecondItem
In the output, you can see that string values, FirstItem and SecondItem, have been returned depending on whether the Items field condition was met.
