Parameters

dependentTable

String

The table that contains the foreign key column. Schema name is optional, if no schema is specified then dbo is assumed.

dependentColumn

String

The foreign key column.

principalTable

String

The table that contains the column this foreign key references. Schema name is optional, if no schema is specified then dbo is assumed.

principalColumn

String

The column this foreign key references. If no value is supplied the primary key of the principal table will be referenced.

cascadeDelete

Boolean

A value indicating if cascade delete should be configured for the foreign key relationship. If no value is supplied, cascade delete will be off.

name

String

The name of the foreign key constraint in the database. If no value is supplied a unique name will be generated.

anonymousArguments

Object

Additional arguments that may be processed by providers. Use anonymous type syntax to specify arguments e.g. 'new { SampleArgument = "MyValue" }'.
