If operator
The If operator evaluates a condition and returns one of two values, depending on the result. If the condition is true, the first value is returned. If the condition is false, the second value is returned.
All three parameters are mandatory.
Example 101.
If the value of a variable is 10 and the condition is that the value must be greater than 5, the result using the If operator is 'true'.
IF(Value > 5, ",Yes", "No")
Example 102.
The operator returns Yes.
