Command-Text Node Constants

  • Article

Note

Indexing Service is no longer supported as of Windows XP and is unavailable for use as of Windows 8. Instead, use Windows Search for client side search and Microsoft Search Server Express for server side search.

 

The command-text node constants are a collection of globally unique identifiers (GUIDs) for the dialect of a command-text node.

DBGUID_SQL92       // Reserved for future use.
DBGUID_DBSQL       // This covers SQL used by OLE DB and ODBC.
                   // Deprecated; use DBGUID_DEFAULT instead.
extern const OLEDBDECLSPEC GUID DBGUID_DEFAULT = \
    {0xc8b521fb,0x5cf3,0x11ce, \
        {0xad,0xe5,0x00,0xaa,0x00,0x44,0x77,0x3d}};
DBGUID_TSQL        // Reserved for future use.
DBGUID_ACCESSSQL   // Reserved for future use.

Remarks

To determine which dialects a provider supports, call IDBProperties::GetProperties for the DBPROP_SQLDIALECTS property. (For more information on using the IDBProperties interface, see the OLE DB Programmer's Reference in the Platform SDK.)
