liquibase.change.AbstractChange

liquibase.change.core.AddLookupTableChange

All Implemented Interfaces:

Change, LiquibaseSerializable

public class AddLookupTableChange
extends AbstractChange

Extracts data from an existing column to create a lookup table. A foreign key is created between the old column and the new lookup table.

Method Detail

validate

public ValidationErrors validate(Database database)

Description copied from class: AbstractChange

Implementation checks the ChangeParameterMetaData for declared required fields and also delegates logic to the SqlGenerator.validate(liquibase.statement.SqlStatement, liquibase.database.Database, liquibase.sqlgenerator.SqlGeneratorChain) method on the SqlStatement objects returned by Change.generateStatements(liquibase.database.Database). If no or null SqlStatements are returned by generateStatements then this method returns no errors. If there are no parameters than this method returns no errors

supports

public boolean supports(Database database)

Description copied from class: AbstractChange

Implementation delegates logic to the SqlGenerator.supports(liquibase.statement.SqlStatement, liquibase.database.Database) method on the SqlStatement objects returned by Change.generateStatements(liquibase.database.Database). If no or null SqlStatements are returned by generateStatements then this method returns true. If AbstractChange.generateStatementsVolatile(liquibase.database.Database) returns true, we cannot call generateStatements and so assume true.

Specified by:

supports in interface Change

Overrides:

supports in class AbstractChange

createInverses

protected Change[] createInverses()

Description copied from class: AbstractChange

Create inverse changes that can roll back this change. This method is intended to be overriden by Change implementations that have a logical inverse operation. Default implementation returns null.

If AbstractChange.generateRollbackStatements(liquibase.database.Database) is overridden, this method may not be called.

Overrides:

createInverses in class AbstractChange

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.

#supportsRollback

generateStatements

public SqlStatement[] generateStatements(Database database)

Description copied from interface: Change

Generates the SqlStatement 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 from Change.generateStatementsVolatile(liquibase.database.Database).

checkStatus

public ChangeStatus checkStatus(Database database)

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 interface Change

Overrides:

checkStatus in class AbstractChange

getConfirmationMessage

public String 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.

getSerializedObjectNamespace

public String getSerializedObjectNamespace()

Specified by:

getSerializedObjectNamespace in interface LiquibaseSerializable

Overrides:

getSerializedObjectNamespace in class AbstractChange
