rollback

The rollback command rolls back changes made to the database based on the specified tag.

Uses

The rollback command is typically used to revert all changes that were made to the database after the tag you specify.

When you run rollback, Liquibase will roll back sequentially all the deployed changes until it reaches the tag row in the DATABASECHANGELOG table. For example, you can use the rollback command when you want to undo a series of changes made to your database related to a specific tag such as a numbered release. If you have tags for release 1, release 2, and release 3, and need to make a correction in release 2, the rollback command will rollback release 3 first.

The following image shows that if we deploy the createTable C changeset and run the rollback --tag=version1 command to revert changes, Liquibase will roll back only createTable C value:

Impact

Using the rollback command comes with risks to your database, so it's important to look for potential unintended consequences before executing this command. You can do this with the rollback-sql command.

Syntax

To run the rollback command, specify the driver, classpath, and URL in the Liquibase properties file. For more information, see Create and Configure a liquibase.properties File. You can also specify these properties in your command line.

Also, before running the rollback command, you need to know the following:

  • If the tag name is unknown to you, you can find it in the DATABASECHANGELOG table.
  • If you don't have any tags specified, you can run the tag command. If you run the tag command to mark the current database state or release, your tag will be applied to the last row in the DATABASECHANGELOG table.
  • If you use the tagDatabase Change Type to create a tag changeset in the changelog file and want to roll back changes applied after this tag, the rollback command will remove all changes made after this tag row and the tag row.
  • If you run the tag command, deploy changesets, and then add the tagDatabase Change Type in your changelog file, your changes and the tag row created by the tagDatabase Change Type will be removed till the command reaches the tag specified with the rollback command.
liquibase rollback --tag=myTag --changelog-file=example-changelog.xml

Note: The --tag=myTag syntax was added in Liquibase 4.4. If you use an older version, specify your tag as a positional argument: <command> myTag.

Command arguments

Tip: For best results, specify all commands and parameters in the --kebab-case format in the CLI. If your preference is camelCase, it also works in the CLI.

Formatted SQL

Liquibase does not support an automatic rollback for formatted SQL changesets. Also, some Change Types have no corresponding rollback commands that can be automatically generated by Liquibase. In these cases, you should add custom rollback statements to the changesets if you want to use rollback commands. For example, in formatted SQL:

-- changeset liquibaseuser:1
create table testTable ( id int primary key, name varchar(255) );
-- rollback drop table testTable;
				
-- changeset liquibaseuser:2
insert into testTable values ('1','The First', 'Country')
insert into testTable values ('2','The Second', 'Country2')
-- rollback delete from testTable where id='1'
-- rollback delete from testTable where id='2'

Override default rollback commands

The <rollback> tag describes how to roll back a change using SQL statements, Change Types, or a reference to a previous changeset. You can use any Change Type in the <rollback> element, such as dropTable or sql:

<changeSet id="1" author="liquibaseuser">
    <createTable tableName="testTable">
        <column name="id" type="int"/>
    </createTable>
    <rollback>
        <dropTable tableName="testTable"/>
    </rollback>
</changeSet>

Alternatively, you can have raw SQL in the content part of the <rollback> element. For example:

<changeSet id="1" author="liquibaseuser">
    <createTable tableName="testTable">
        <column name="id" type="int"/>
    </createTable>
    <rollback>
        drop table testTable
    </rollback>
</changeSet>

Liquibase treats the raw SQL within <rollback> the same as in the <sql> Change Type, with stripComments set to true, splitStatements set to true, and endDelimiter set to ;. For more details, see the XML example from the sql documentation.

- changeSet:
    id: 1
    author: liquibaseuser
    changes:
      - createTable:
          tableName: testTable
          columns:
            - column:
                name: id
    rollback:
      - dropTable:
          tableName: testTable
{
  "changeSet": {
    "id": 1,
    "author": "liquibaseuser",
    "changes": [
      {
        "createTable": {
          "tableName": "testTable"
        }
      }
    ],
    "rollback": [
      {
        "dropTable": {
          "tableName": "testTable"
        }
      }
    ]
  }
}

Multiple rollbacks

You can also specify multiple Change Types within a single <rollback> statement or across multiple <rollback> statements:

Change Type syntax:

<changeSet id="multiRollbackTest" author="liquibaseuser">
    <createTable tableName="multiRollback1">
        <column name="id" type="int"/>
    </createTable>
    <createTable tableName="multiRollback2">
        <column name="id" type="int"/>
    </createTable>
    <createTable tableName="multiRollback3">
        <column name="id" type="int"/>
    </createTable>
    <rollback>
        <dropTable tableName="multiRollback1"/>
        <dropTable tableName="multiRollback2"/>
    </rollback>
    <rollback>
      <dropTable tableName="multiRollback3"/>
    </rollback>
</changeSet>

Raw SQL:

<changeSet id="multiRollbackTest" author="liquibaseuser">
    <createTable tableName="multiRollback1">
        <column name="id" type="int"/>
    </createTable>
    <createTable tableName="multiRollback2">
        <column name="id" type="int"/>
    </createTable>
    <createTable tableName="multiRollback3">
        <column name="id" type="int"/>
    </createTable>
    <rollback>
        drop table multiRollback1;
        drop table multiRollback2;
    </rollback>
    <rollback>drop table multiRollback3</rollback>
</changeSet>
- changeSet:
    id: multiRollbackTest
    author: liquibaseuser
    changes:
      - createTable:
          tableName: multiRollback1
          columns:
            - column:
                name: id
      - createTable:
          tableName: multiRollback2
          columns:
            - column:
                name: id
      - createTable:
          tableName: multiRollback3
          columns:
            - column:
                name: id
    rollback:
      - dropTable:
          tableName: multiRollback1
      - dropTable:
          tableName: multiRollback2
    rollback:
      - dropTable:
          tableName: multiRollback3
{
  "changeSet": {
    "id": multiRollbackTest,
    "author": "liquibaseuser",
    "changes": [
      {
        "createTable": {
          "tableName": "multiRollback1",
          "columns": [
            {
              "column": {
                "name": "id"
              }
            }
          ]
        },
        "createTable": {
          "tableName": "multiRollback2"
          "columns": [
            {
              "column": {
                "name": "id"
              }
            }
          ]
        },
        "createTable": {
          "tableName": "multiRollback3"
          "columns": [
            {
              "column": {
                "name": "id"
              }
            }
          ]
        }
      }
    ],
    "rollback": [
      {
        "dropTable": {
          "tableName": "multiRollback1"
        },
        "dropTable": {
          "tableName": "multiRollback2"
        }
      }
    ],
    "rollback": [
      {
        "dropTable": {
          "tableName": "multiRollback3"
        }
      }
    ],
  }
}

Directly reference changeset

The following example shows how you can use a <rollback> tag to reference the changeset that originally created a statement, in this case using changeset 2 to implement rollback logic against changeset 1:

-- changeset liquibaseuser:1
create table testTable ( id int primary key, name varchar(255) );

-- changeset liquibaseuser:2
-- rollback drop table testTable;
-- rollback changeSetId: 1 changeSetAuthor: liquibaseuser changeSetPath:optional/path/to/myChangeLog.sql
<changeSet id="1" author="liquibaseuser">
    <createTable tableName="testTable"/>
</changeSet>

<changeSet id="2" author="liquibaseuser">
    <dropTable tableName="testTable"/>
    <rollback changeSetId="1" changeSetAuthor="liquibaseuser" changeSetPath="optional/path/to/myChangeLog.xml"/>
</changeSet>
- changeSet:
    id: 1
    author: liquibaseuser
    changes:
      - createTable:
          tableName: testTable
          columns:
            - column:
                name: id
- changeSet:
    id: 2
    author: liquibaseuser
    rollback:
      - dropTable:
          tableName: testTable
      changeSetId: 1
      changeSetAuthor: liquibaseuser
      changeSetpath: optional/path/to/myChangeLog.yaml
{
  "changeSet": {
    "id": 1,
    "author": "liquibaseuser",
    "changes": [
      {
        "createTable": {
          "tableName": "testTable"
        }
      }
    ]
{
  "changeSet": {
    "id": 2,
    "author": "liquibaseuser",
    "changes": [
      {
        "createTable": {
          "tableName": "testTable"
        }
      }
    ],
    "rollback": [
      {
        "dropTable": {
          "tableName": "testTable"
        }
      },
      "changeSetId": "1",
      "changeSetAuthor": "liquibaseuser",
      "changeSetPath": "optional/path/to/myChangeLog.json"
    ]
  }
}

Empty rollback statements

If you do not want to revert a change in a rollback mode, use either the keyword empty or the keyword not required inside the rollback tag. In XML, YAML, and JSON changelogs, you can also use an empty string inside the rollback tag.

-- changeset liquibaseuser:1
create table testTable ( id int primary key, name varchar(255) );
-- rollback empty
<changeSet id="3" author="liquibaseuser">
    <createTable tableName="testTable">
        <column name="id" type="int"/>
    </createTable>
    <rollback>empty</rollback>
</changeSet>

You can also use an empty string (<rollback></rollback>) or a self-closing-tag (<rollback/>).

- changeSet:
    id: 1
    author: liquibase
    changes:
      - createTable:
          tableName: testTable
          columns:
            - column:
                name: id
                type: int
    rollback: empty

You can also use an empty string (rollback: "").

{
  "changeSet": {
    "id": 1,
    "author": "example",
    "changes": [
      {
        "createTable": {
          "tableName": "testTable",
          "columns": [
            {
              "column": {
                "name": "id",
                "type": "int"
              }
            }
          ]
        }
      }
    ],
    "rollback": "empty"
  }
}

You can also use an empty string ("rollback": "").

When successful, the rollback command produces the following output:

Liquibase Version: 4.9.1
Rolling Back Changeset: example-changelog.sql::2::Amber.Williams
Rolling Back Changeset: example-changelog.sql::1::Amber.Williams
Liquibase command 'rollback' was executed successfully.
Liquibase: Rollback has been successful.
