generateStatements
Generates theSqlStatement
objects required to run the change for the given database. NOTE: This method may be called multiple times throughout the changelog execution process and may be called in documentation generation and other integration points as well. If this method reads from the current database state or uses any other logic that will be affected by whether previous changeSets have ran or not, you must return true fromChange.generateStatementsVolatile(liquibase.database.Database)
. -
checkStatus
Description copied from interface:Change
Validate that this change executed successfully against the given database. This will check that the update completed at a high level plus check details of the change. For example, a change to add a column will check that the column exists plus data type, default values, etc.- Specified by:
checkStatus
in interfaceChange
- Overrides:
checkStatus
in classAbstractChange
-
getConfirmationMessage
Description copied from interface:Change
Confirmation message to be displayed after the change is executed. Should include relevant configuration settings to make it as helpful as possible. This method may be called outside the changelog execution process, such as in documentation generation. -
createInverses
Description copied from class:AbstractChange
Create inverse changes that can roll back this change. This method is intended to be overridden by Change implementations that have a logical inverse operation. Default implementation returns null. IfAbstractChange.generateRollbackStatements(liquibase.database.Database)
is overridden, this method may not be called.- Overrides:
createInverses
in classAbstractChange
- Returns:
- Return null if there is no corresponding inverse and therefore automatic rollback is not possible. Return an empty array to have a no-op rollback.
