It's not an error that 0 rows are fetched, i don't understand why fillRectifica (toracleouput) it's trying to insert if there are no rows. I need to figure out a way to filter the insertion in case 0 rows pass throught the filterNull filter. Thank you for your help.
EDITION 2016-12-17 SOLVED: The problem is not that the tOracleOutput is trying to insert a null row, but that the if condition in at it's output doesn't find the variable to evaluate. Thanks
