BUG #: 58497 (SQLBUG_70)



SYMPTOMS
When running a stored procedure that contains indexed local temporary tables, and SELECT or UPDATE statements on the tables, you may get an exception access violation (AV). The connection may seem to stop responding (hang), and may eventually time out with an error that resembles the following:

Time out occurred while waiting for buffer latch type 1, bp 0x117a6900,

page (0:0), stat 0x40d, object ID 2:611966976:0, waittime 500. Continuing to wait.

You may also receive one of the following errors:

Error: 602, Severity: 21, State: 13

Could not find row in sysindexes for database ID 2, object ID 181575685, index ID 1. Run DBCC CHECKTABLE on sysindexes..

Error: 602, Severity: 21, State: 13

Could not find row in sysindexes for database ID 2, object ID 213575799, index ID 1. Run DBCC CHECKTABLE on sysindexes..

-or-

Error: 5180, Severity: 22, State: 1

2000-09-30 15:54:24.79 spid8 Could not open FCB for invalid file ID 0 in database 'tempdb'. Table or database may be corrupted..



CAUSE
SQL Server caches index IDs in the compiled plan. However, the stored procedure can be such that for a different invocation this cached index ID belongs to a different index on the local temporary table. A check for sharing and reusing plans does not seem to catch this, and SQL Server uses the old plan for this invocation. In addition, auto-create and auto-drop statistics that are used in the query plan do not keep track of the temporary table, which results in the errors.
