| updateTestingRollback command | Updates the database, then rolls back changes before updating again. |
Diff commands
| Command | Description |
|---|---|
| generateChangeLog command | Generate a changelog from a database when adding Liquibase to a new project. Conceptually, does a diff of the current database to an empty database, creating a changelog that has all the changes needed to update an empty database. |
| diff command | Writes description of differences between two databases to standard out. |
| diffChangeLog command | Adds any differences between the databases specified to a changelog. Can append in any of the supported changelog formats. |
Documentation commands
| Command | Description |
|---|---|
| dbDoc <outputDirectory> command | Generates Javadoc-like documentation based on current database and changelog. |
Maintenance commands
| Command | Description |
|---|---|
| changelogSync command | Mark all changes as executed in the database. |
| changelogSyncSQL command | Writes SQL to mark all changes as executed in the database to STDOUT. |
| clearCheckSums command | Removes current checksums from database. On next update changesets that have already been deployed will have their checksums recomputed, and changesets that have not been deployed will be deployed. |
| dropAll command | Drops all database objects owned by the user. DANGEROUS! |
| listLocks command | Lists who currently has locks on the database changelog. |
| markNextChangeSetRan command | Mark the next change set as executed in the database. |
| releaseLocks command | Releases all locks on the database changelog. |
| status --verbose command | Outputs count (list if --verbose) of changesets that have not been run. |
