There is an option with compare called "quickcheck" and this can be used to achieve this.
It performs an initial check to determine if any rows are Out Of Sync (OOS).
As soon as one OOS row is detected, the process stops.
No further information is returned.
No OOS row information is logged to the compare SQL file.
Do not use this option with the key option or any of the where options.
This option does not support LONG columns.
Example:
sp_ctrl> compare source_owner.source_table quickcheck
