Element Type Definition
| Element Type Name | JOIN_CONSTRAINT |
| Short Name | JCO |
| View Name | CI_JOIN_CONSTRAINTS |
| Description | Definition of a foreign key constraint or a domain contraint |
| Sub-type of | CONSTRAINT |
| Non-instantiable super-type of | DOMAIN_CONSTRAINT |
| FOREIGN_KEY_CONSTRAINT | |
| As this is a non-instantiable supertype, follow links (above) to its instantiable subtypes to find versioning information for each subtype, uniqueness criteria, API rules etc | |
| Underlying table: | SDD_OCO |

Prompt: Complete ? Uppercase Defined on OCO supertype | YESNO | Y |
| CONSTRAINT_TYPE | VARCHAR2(10) | N | Sub-type discriminator. Internal property indicating the type of CONSTRAINT i.e. PRIMARY, UNIQUE, CHECK, FOREIGN or DOMAIN
Not displayed Uppercase System maintained Not updatable by user Defined on OCO supertype | OCO_CONSTRAINT_TYPE | |
| DEFER_STATUS | VARCHAR2(16) | N | Indicates whether constraint checking can be deferred until the end of the transaction (as opposed to end of each DML statement)
Prompt: Defer Status Uppercase Defined on OCO supertype | DEFER_STATUS | NOT DEFERRED |
| ERROR_MESSAGE | VARCHAR2(70) | Y | An error message that is issued when data violates the constraint.
Prompt: Error Message Defined on OCO supertype | ||

Prompt: Mandatory ? Uppercase | YESNO | Y |
| NAME | VARCHAR2(30) | N | The name of the key constraint.
Prompt: Name Uppercase Defined on OCO supertype | ||
| PARENT_IVID | NUMBER(38, 0) | Y | Internal use only. Exists on "secondary" element types from a versioning viewpoint. Contains the IVID of the primary element type (not necessarily a PAC) forming the basis of the "versionable object" to which this element type belongs
Not displayed System maintained Updatable only if null Defined on SAC supertype | ||
| PAC_REFERENCE | NUMBER(38, 0) | Y | Internal use only. Exists on "secondary" element types from a structural viewpoint. Contains the IRID of the PAC forming the basis of the "logical object" to which this element type belongs
