The EnumReferencedKeys method returns a QueryResults object enumerating the PRIMARY KEY and UNIQUE constraints.
object.EnumReferencedKeys( [ ReferencedTable ] , [ IncludeAll ] )
as QueryResults
| Part | Description |
|---|---|
| object | Expression that evaluates to an object in the Applies To list |
| ReferencedTable | Optional. String naming an existing Microsoft® SQL Server™ table. Restricts result set membership to list only references to objects defined on the specified table. |
| IncludeAll | True or False. |
A QueryResults object containing one result set defined by these columns.
| Column | Data type | Description |
|---|---|---|
| candidate_table | nvarchar(262) | Name of a table on which a PRIMARY KEY or UNIQUE constraint is defined |
| candidate_key | nvarchar(129) | Name of a PRIMARY KEY or UNIQUE constraint |
| referenced | bit | When 1, the table depends on the PRIMARY KEY or UNIQUE constraint listed in the result set |
When IncludeAll is True, the result set enumerates all PRIMARY KEY and UNIQUE constraints defined in the database. The value of the result set column referenced determines table object dependency on the listed PRIMARY KEY or UNIQUE constraint.
When IncludeAll is False (default), the result set enumerates only those PRIMARY KEY or UNIQUE constraints on which the table depends.
