Command line output explanation

I'm using SQL Data Compare to do a command line sync using a project set up in the GUI. I call the project like so:

"c:\program files\red gate\sql data compare 8\sqldatacompare.exe" /project:"C:\Users\Administrator\Documents\SQL Data Compare\SharedProjects\my-database-sync-project.sdc"

I couldn't find documentation on what exactly the "<<" "<>" ">>" indicators mean under the "DB1" and "DB2" headings in the output.

When DB1 is >> and DB2 is blank, I assume new records were pushed from DB1 to DB2. Fine.

However when I see DB1 <> and DB2 <> on the same line for the same table, I'm confused about what's going on.

Of most concern is seeing DB1 blank, and DB2 << which seems to indicate DB2 pushed changes back to DB1. I definitely don't want this to happen given that the project was set up in the GUI to go in one direction, from DB1 to DB2. I hope the command line version is not actually syncing some data the opposite way from DB2 to DB1?

    Hi paule123,

    Here is what the output of the command line means:

    When comparing DB1 with DB2:

    == == Identical objects

    <> <> Different objects

    << Objects that exist in DB2 that don't exist in DB1

    >> Objects that exist in DB1 that don't exist in DB2

    Best Regards,
