Identifies the expression that is applied by the transform. The
value parameter can be one of the following types:
- test predicates that evaluate to Boolean values (
value: myAge == '30'yields a
- computational expressions (
The expected type of
value expression is determined by the transform type. Each type of expression can contain combinations of the following:
- literal values:
value: 'Hello, world'
- column references:
value: amountOwed * 10
value: left(myString, 4)
The types of any generated values are re-inferred by the platform.
