- 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" }'.
