EnumReferencedTables Method
Dieses Feature wird in einer zukünftigen Version von Microsoft SQL Server entfernt. Verwenden Sie dieses Feature beim Entwickeln neuer Anwendungen nicht, und planen Sie das Ändern von Anwendungen, in denen es zurzeit verwendet wird.
The EnumReferencedTables method returns a QueryResults object that enumerates tables on which a PRIMARY KEY or UNIQUE constraint is defined.
Syntax
object
.EnumReferencedTables( [ IncludeAll ] ) as QueryResults
Parts
- object
Expression that evaluates to an object in the Applies To list
- IncludeAll
TRUE or FALSE
Prototype (C/C++)
HRESULT EnumReferencedTables(
LPSQLDMOQUERYRESULTS* ppResults,
BOOL IncludeAllCandidates = NULL);
Returns
A QueryResults object that contains one result set defined by these columns.
| Column | Data type | Description |
|---|---|---|
candidate_key |
nvarchar(129) |
Not applicable. Contains the string N/A. |
candidate_table |
nvarchar(262) |
Name of the table on which the PRIMARY KEY or UNIQUE constraint is defined. |
referenced |
bit |
When 1, the table referenced by the Table object used depends on the result-set listed table in a FOREIGN KEY relationship. |
Hinweise
When IncludeAll is TRUE, the result set enumerates all tables on which PRIMARY KEY and UNIQUE constraints are defined. The value of the referenced column in the result set determines table object dependency on the table listed in the result set.
When IncludeAll is FALSE (default), the result set enumerates only those tables that contain PRIMARY KEY or UNIQUE constraints and on which the referenced table depends.
