[!INCLUDE SQL Server]
Important

The [!INCLUDEssNoVersion] Native Client OLE DB provider also supports returning schema information from a linked server when processing [!INCLUDEtsql] distributed queries.
Note
Although [!INCLUDEssNoVersion] supports synonyms, metadata for synonyms is not returned by [!INCLUDEssNoVersion] Native Client.
The following tables list schema rowsets and the restriction columns supported by the [!INCLUDEssNoVersion] Native Client OLE DB provider.
| Schema rowset | Restriction columns |
|---|---|
| DBSCHEMA_CATALOGS | CATALOG_NAME |
| DBSCHEMA_COLUMN_PRIVILEGES | All the restrictions are supported. TABLE_CATALOG TABLE_SCHEMA TABLE_NAME COLUMN_NAME GRANTOR GRANTEE |
| DBSCHEMA_COLUMNS | All the restrictions are supported. TABLE_CATALOG TABLE_SCHEMA TABLE_NAME COLUMN_NAME The following additional columns are specific to [!INCLUDEssNoVersion]: COLUMN_LCID, which is the locale ID of the collation. COLUMN_LCID is the same value as a Windows LCID. COLUMN_COMPFLAGS defines which comparisons are supported for the collation. The data format is the same as DBPROP_FINDCOMPAREOPS. COLUMN_SORTID, which is the [!INCLUDEssNoVersion] sorting style for the collation. COLUMN_TDSCOLLATION, which is the [!INCLUDEssNoVersion] collation for the column. IS_COMPUTED, which is VARIANT_TRUE if the column is a computed column and VARIANT_FALSE otherwise. |
