Description

The COMPARE TABLE command compares two tables, <tablename1> and <tablename2>, 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.

Complete databases can be compared using the COMPARE DATABASE command.

Example

compare table southwind!customers with southwind_20190304!customers to file upgrade.prg
