Row Status

The cursor library creates a buffer in the cache for the row status. The cursor library retrieves values for the row status array (specified with the SQL_ATTR_ROW_STATUS_PTR statement attribute) from this buffer. For each row, the cursor library sets this buffer to:

SQL_ROW_DELETED when it executes a positioned delete statement on the row.

SQL_ROW_ERROR when it encounters an error retrieving the row from the data source with SQLFetch.

SQL_ROW_SUCCESS when it successfully fetches the row from the data source with SQLFetch.

SQL_ROW_UPDATED when it executes a positioned update statement on the row.
