I would really appreciate if somebody could help me.
I have been developing with Visual Basic 6.0 and Sql-Server 7.0 and I have
launched some queries that return an error very rare for me.
This is the message error:

Error '-2147217900 (80040e14)' runtime error:

SqlDumpExceptionHandler; the process 38 generated a fatal exception c0000005
EXCEPTION_ACCESS_VIOLATION, SQL Server terminates this process.

But the most rare thing is that sometimes the query works and sometimes does

Thanks in advance...
