Method Summary

Modifier and TypeMethod and Description
private List<DropForeignKeyConstraintChange>

Returns:

the list of generated DropForeignKeyConstraintChanges
generateChildren(Database
the database type for which subchanges need to be generated
database)

Iterates through all the FOREIGN KEYs of the target table and outputs a list of DropForeignKeyConstraintChanges for a given database type.

public SqlStatement[]
generateStatements(Database database)

Implements liquibase.change.Change.generateStatements.

Generates the SqlStatement objects required to run the change for the given database.

public boolean
generateStatementsVolatile(Database database)

Overrides liquibase.change.AbstractChange.generateStatementsVolatile.

Implements liquibase.change.Change.generateStatementsVolatile.

Implementation delegates logic to the liquibase.sqlgenerator.SqlGenerator#generateStatementsIsVolatile(Database) method on the SqlStatement objects returned by generateStatements.

Method Detail

generateChildrenback to summary
private List<DropForeignKeyConstraintChange> generateChildren(Database database)

Iterates through all the FOREIGN KEYs of the target table and outputs a list of DropForeignKeyConstraintChanges for a given database type.

Parameters
database:Database

the database type for which subchanges need to be generated

Returns:List<DropForeignKeyConstraintChange>

the list of generated DropForeignKeyConstraintChanges

generateStatementsback to summary
public SqlStatement[] generateStatements(Database database)

Implements liquibase.change.Change.generateStatements.

Doc from liquibase.change.Change.generateStatements.

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 generateStatementsVolatile.

public boolean generateStatementsVolatile(Database database)

Overrides liquibase.change.AbstractChange.generateStatementsVolatile.

Implements liquibase.change.Change.generateStatementsVolatile.

Doc from liquibase.change.AbstractChange.generateStatementsVolatile.

Implementation delegates logic to the liquibase.sqlgenerator.SqlGenerator#generateStatementsIsVolatile(Database) method on the SqlStatement objects returned by generateStatements. If zero or null SqlStatements are returned by generateStatements then this method returns false.

Implements liquibase.change.Change.getConfirmationMessage.

Doc from liquibase.change.Change.getConfirmationMessage.

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.
