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 atrueorfalsevalue), or - computational expressions (
value: abs(pow(myCol,3))).
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 functions:
value: left(myString, 4)combinations:
value: abs(pow(myCol,3))
The types of any generated values are re-inferred by the platform.
