SQLNativeSql (Cursor Library)

  • Artikkeli

Important

This feature will be removed in a future version of Windows. Avoid using this feature in new development work and plan to modify applications that currently use this feature. Microsoft recommends using the driver's cursor functionality.

This topic discusses the use of the SQLNativeSql function in the cursor library. For general information about SQLNativeSql, see SQLNativeSql Function.

If the driver supports this function, the cursor library calls SQLNativeSql in the driver and passes it the SQL statement. For positioned update, positioned delete, and SELECT FOR UPDATE statements, the cursor library modifies the statement before passing it to the driver.

Note

The cursor library incorrectly returns SQLSTATE 34000 (Invalid cursor name) if the cursor name is invalid in a positioned update or delete statement that is passed in the InStatementText argument of SQLNativeSql. SQLNativeSql is not intended to return syntax errors, which are returned only upon statement preparation or execution.
