In a Transformer expression for a stage variable, there is a nullable input column. Assume the legacy NULL processing option is turned off. What happens when a row is processed that contains NULL in that input column?
You are processing groups of rows in a Transformer. The first row in each group contains "1" in the Flag column and "0" in the remaining rows of the group. At the end of each group you want to sum and output the QTY column values. Which technique will enable you to retrieve the sum of the last group?
The derivation for a stage variable is: Upcase(input_column1) : ' ' : Upcase(input_column2). Suppose that input_column1 contains a NULL value. Assume the legacy NULL processing option is turned off. Which behavior is expected?
