The executeCommand Change Type executes a system command.

Note: Using Liquibase commands such as migrateSQL may not work as expected because the executeCommand Change Type doesn't generate SQL. To resolve this, use Change Types that generate SQL.


You can typically use the executeCommand Change Type to run a script using a specific executable. One reason to use executeCommand is to insert or update data.
