  Hi All,

  We have a very narrow data table where I need to capture the date a specific value is inserted into specific column. The table is a Type 2 SCD that I'm loading via SSIS and using a MERGE statement. Whenever a value of 'Y' is inserted into a specific column I need to log the Account number, Value, and date in an audit table. The original value would be NULL. Any guidance would be very much appreciated.

  I was hoping I could do it via trigger on the destination table as opposed to performing a look-up and insert in staging prior to load. Thanks!

  We would need to know what the whole table looks like. Please post the CREATE TABLE statement for it and the Audit table.

  RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
  First step towards the paradigm shift of writing Set Based code:
  ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.
  "Change is inevitable... change for the better is not".
