| Hi,I have the following information:AccNum, StatementDate, Amount, etc etc etcThis is a big query which is then loaded into a staging table, my goal is to reduce the load time, as I want to avoid loading the entire data everytime and only processing what I havent loaded already.Is there a way I can use the statementdate and run my SP to look at the last statement date and load based on that?Thanks |
