public class FKConstraint
extends ColumnConstraint

A FKConstraint represents a Foreign Key Constraint. A foreign key constraint requires values in the constrained table to match values in another table.

An FKConstraint contains a reference to a UniqueConstraint. This referenced constraint determines the valid values for the columns constrained.

Constructor Detail

FKConstraint

public FKConstraint()

Constructs a new FKConstraint.

FKConstraint

public FKConstraint(java.lang.String name,
                    Relation relation)

Constructs a new FKConstraint with the specified name for the specified relation. The new constraint will not be added to the Table, this must be done using Relation.addConstraint(Constraint) when the constraint definition is complete.

Parameters:

name - a string containing the name of the constraint

relation - the relation being constrained.

Method Detail

setReferenceID

public void setReferenceID(DBObjectID id)

Sets the Object ID of the referenced unique constraint.

Parameters:

id - The DBObjectID of the referenced constraint

getReferenceID

public DBObjectID getReferenceID()

Retrieves the Object ID of the referenced unique constraint.

Returns:

The DBObjectID of the referenced constraint

getConstraintType

public java.lang.String getConstraintType()

Description copied from class: Constraint

Retrieves the type of constraint represented by this instance. Valid constraint types can vary depending on the database. Examples of constraint types include primary key constraints, foreign key constraints, and check constraints.

Specified by:

getConstraintType in class Constraint

Returns:

a string value indicating the type of constraint.

getOnDeleteAction

public FKConstraint.ReferentialAction getOnDeleteAction()

Gets the "referential action" that the database will take on delete of a row contained in the referenced table.

setOnDeleteAction

public void setOnDeleteAction(FKConstraint.ReferentialAction action)

Sets the "referential action" that the database will take on delete of a row contained in the referenced table.

getDeleteMode

@Deprecated
public int getDeleteMode()

Deprecated. replaced by getOnDeleteAction()

setDeleteMode

@Deprecated
public void setDeleteMode(int onDelete)

Deprecated. replaced by setOnDeleteAction(oracle.javatools.db.FKConstraint.ReferentialAction)
