SYMPTOMS
When you run a SELECT statement on a table that contains one or
more computed columns and the SELECT statement contains invalid parameter values for the filter conditions, an
access violation may occur.
The SELECT statement that contains the invalid parameter values may run successfully if Microsoft SQL Server 2000 already stores a query execution plan that was generated by using valid parameters for the same SELECT statement. If you clear the SQL Server procedure cache and then run the SELECT statement again with invalid parameter values, the problem may occur again.
When the access violation occurs, you may notice a stack dump file that is similar to the
following:
* *******************************************************************************
*
* BEGIN STACK DUMP:
* 05/14/03 21:31:23 spid 63
*
* Exception Address = 00747D1A (CConvertCtx::PboWithComputedColumnDependencies + 000000E7 Line 0+00000000)
* Exception Code = c0000005 EXCEPTION_ACCESS_VIOLATION
* Access Violation occurred reading address 00000014
You may also notice a short stack dump file that is similar
to the following:
