BUG #: 56218 (SQLBUG_70)



SYMPTOMS
An update to all rows in the current fetch buffer (through sp_cursor), with a cursor based on a view, may fail with the following error:

Process 7 unlocking unowned resource: TAB: 5:982827855 []

spid7 Error: 1203, Severity: 20, State: 1

spid7 Process ID 7 attempting to unlock unowned resource TAB: 5:982827855 []..

This problem is specific to the use of extended cursor procedures since ANSI T-SQL only supports an update of a single row WHERE CURRENT OF. An ODBC application might encounter this error when updating all rows in the fetch buffer through a SQLSetPos API call.



WORKAROUND
Here are two ways to work around this behavior:
 * Use only one row in the fetch buffer.

-or-
 * Update the cursor against the base table.



STATUS
Microsoft has confirmed this to be a problem in SQL Server 7.0. This problem has been corrected in U.S. Service Pack 2 for Microsoft SQL Server 7.0. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
