SYMPTOMS

When you run a query in Microsoft SQL Server 2000, an access violation may occur. You experience this problem when the following conditions are true:
  • A table has a multicolumn index such as Table1(col1, col2).
  • The columns of the table do not accept the value NULL.
  • The query uses a predicate that resembles the following: 
    Table1.col1	>= @p1 and Table1.col2 > @p2.
When this problem occurs, the following error message may be logged in the SQL Server Errorlog file:
- BEGIN STACK DUMP:
* <Date> <Time> spid 86
*
* Exception Address = 00450973
* Exception Code = c0000005 EXCEPTION_ACCESS_VIOLATION
* Access Violation occurred reading address 00000000
...
<Date> <Time> spid86 Stack Signature for the dump is 0x828F490D
<Date> <Time> spid86 Error: 0, Severity: 19, State: 0
<Date> <Time> spid86 language_exec: Process 86 generated an access violation. SQL Server is terminating this process..
<Date> <Time> spid86 Using 'dbghelp.dll' version '4.0.5'
