updateCountSQL <value> command

The updateCountSQL <value> command is a helper command that inspects the SQL Liquibase will run while using the updateCount <value> command.

Uses

The updateCountSQL <value> command is used to inspect the raw SQL before running the updateCount <value> command, so you can correct any issues that may arise before running the command. Liquibase uses the raw SQL to apply a specified number of database changes you have added to the changelog file.

Running the updateCountSQL <value> command

To run the updateCountSQL <value> command, you need to specify your driver, class path, URL, and user authentication information in the liquibase.properties file. You can also specify these in your command line.

Then run the updateCountSQL <value> command:

liquibase --changeLogFile=postgres_lbpro_master_changelog.xml updateCountSQL 2

Note: Enter the name of the changelog and the number that you want to use in place of postgres_lbpro_master_changelog.xmland 2.
