Description

The COMPARE DATABASE command compares two databases, <database1 name> and <database2 name>, and optionally generates an upgrade script, <filename.prg>, that can be packaged up and uploaded to a live system. A script named upgrade.prg (compiled to upgrade.dbo) is automatically detected and installed by the Lianja Cloud Server without requiring any machine downtime when included in a deployed Lianja Package File.

Example

compare database southwind with southwind_20190304 to file upgrade.prg
