{DTLIMTYPE=BA|AI|TU} Escape Sequence

{DTLIMTYPE=BA|AI|TU} Escape Sequence

Enables users to specify the capture image type when accessing PowerExchange Change Data Capture through ODBC:
  • BA
    . Delivers the before image (before the latest change) and the after image (the latest change). The before image is shipped with an action character forcing the deletion of the record. The after image (which includes the change data) is in the format of an Insert.
  • AI
    . Delivers only the after image data for the update.
  • TU
    . Delivers the data before and after images as they occur. The before image is shipped to enable the application to ensure nothing has changed in that record since the request. The after image comes through as a change (or Update) record. The update is still a full image but the application picking this up will be able to change the target record rather than Delete it and Insert the new one as when using BA.
