| ERROR | RETURN statement in a pipelined function cannot contain an expression |
| CAUSE | A RETURN statement in a pipelined function contains an expression, which is not allowed. Pipelined functions must send back values to the caller by using the PIPE statement. |
| ACTION | Remove the expression from the RETURN statement and use a PIPE statement to return values. Else, convert the function into a non-pipelined function. |
