Interface ConstraintForeignKeyOnStep

All Superinterfaces:

Constraint, ConstraintFinalStep, FieldOrConstraint, Named, QueryPart, java.io.Serializable

public interface ConstraintForeignKeyOnStep
extends ConstraintFinalStep

The step in the Constraint construction DSL API that allows for adding ON DELETE and ON UPDATE clauses.

Referencing XYZ*Step types directly from client code

It is usually not recommended to reference any XYZ*Step types directly from client code, or assign them to local variables. When writing dynamic SQL, creating a statement's components dynamically, and passing them to the DSL API statically is usually a better choice. See the manual's section about dynamic SQL for details: https://www.jooq.org/doc/latest/manual/sql-building/dynamic-sql.

Drawbacks of referencing the XYZ*Step types directly:

• They're operating on mutable implementations (as of jOOQ 3.x)
• They're less composable and not easy to get right when dynamic SQL gets complex
• They're less readable
• They might have binary incompatible changes between minor releases

Method Detail

onDeleteNoAction

@Support
ConstraintForeignKeyOnStep onDeleteNoAction()

Add an ON DELETE NO ACTION clause to the FOREIGN KEY constraint.

This is the standard action according to the SQL standard. If a given SQLDialect does not support setting this action explicitly, no explicit action will be specified and calling this method is equivalent to not calling any method at all.

onDeleteRestrict

@Support({ACCESS,ASE,AURORA_MYSQL,AURORA_POSTGRES,CUBRID,DB2,DERBY,H2,HANA,HSQLDB,INGRES,MARIADB,MEMSQL,MYSQL,POSTGRES,SQLITE,SYBASE})
ConstraintForeignKeyOnStep onDeleteRestrict()

Add an ON DELETE RESTRICT clause to the FOREIGN KEY constraint.

onDeleteCascade

@Support
ConstraintForeignKeyOnStep onDeleteCascade()

Add an ON DELETE CASCADE clause to the FOREIGN KEY constraint.

onDeleteSetNull

@Support({ACCESS,ASE,AURORA_MYSQL,AURORA_POSTGRES,CUBRID,DB2,DERBY,FIREBIRD,H2,HANA,HSQLDB,INFORMIX,INGRES,MARIADB,MEMSQL,MYSQL,ORACLE,POSTGRES,SQLITE,SQLSERVER,SYBASE})
ConstraintForeignKeyOnStep onDeleteSetNull()

Add an ON DELETE SET NULL clause to the FOREIGN KEY constraint.

onDeleteSetDefault

@Support({ACCESS,ASE,AURORA_MYSQL,AURORA_POSTGRES,CUBRID,FIREBIRD,H2,HANA,HSQLDB,INGRES,MEMSQL,MYSQL,POSTGRES,SQLITE,SQLSERVER,SYBASE})
ConstraintForeignKeyOnStep onDeleteSetDefault()

Add an ON DELETE SET DEFAULT clause to the FOREIGN KEY constraint.

onUpdateNoAction

@Support
ConstraintForeignKeyOnStep onUpdateNoAction()

Add an ON UPDATE NO ACTION clause to the FOREIGN KEY constraint.

This is the standard action according to the SQL standard. If a given SQLDialect does not support setting this action explicitly, no explicit action will be specified and calling this method is equivalent to not calling any method at all.

onUpdateRestrict

@Support({ACCESS,ASE,AURORA_MYSQL,AURORA_POSTGRES,CUBRID,DB2,DERBY,H2,HANA,HSQLDB,INGRES,MARIADB,MEMSQL,MYSQL,POSTGRES,SQLITE,SYBASE})
ConstraintForeignKeyOnStep onUpdateRestrict()

Add an ON UPDATE RESTRICT clause to the FOREIGN KEY constraint.

onUpdateCascade

@Support({ACCESS,ASE,AURORA_MYSQL,AURORA_POSTGRES,CUBRID,FIREBIRD,H2,HANA,HSQLDB,INGRES,MARIADB,MEMSQL,MYSQL,POSTGRES,SQLITE,SQLSERVER,SYBASE})
ConstraintForeignKeyOnStep onUpdateCascade()

Add an ON UPDATE CASCADE clause to the FOREIGN KEY constraint.

onUpdateSetNull

@Support({ACCESS,ASE,AURORA_MYSQL,AURORA_POSTGRES,CUBRID,FIREBIRD,H2,HANA,HSQLDB,INGRES,MARIADB,MEMSQL,MYSQL,POSTGRES,SQLITE,SQLSERVER,SYBASE})
ConstraintForeignKeyOnStep onUpdateSetNull()

Add an ON UPDATE SET NULL clause to the FOREIGN KEY constraint.

onUpdateSetDefault

@Support({ACCESS,ASE,AURORA_MYSQL,AURORA_POSTGRES,CUBRID,FIREBIRD,H2,HANA,HSQLDB,INGRES,MEMSQL,MYSQL,POSTGRES,SQLITE,SQLSERVER,SYBASE})
ConstraintForeignKeyOnStep onUpdateSetDefault()

Add an ON UPDATE SET DEFAULT clause to the FOREIGN KEY constraint.
