BUG: Sp_cursoropen Causes AV on the Initial Execution After LOAD

ID: Q221176

The information in this article applies to:
BUG #: 18544 (SQLBUG_65)

SYMPTOMS

Using the sp_cursoropen stored procedure with any cursor type causes a handled access violation (AV) on the initial execution after loading a database.

If a trace flag 7502 is enabled, SQL Server returns error 225 to the client:

Cannot run query--referenced object (name NAME NOT RECOVERABLE) dropped during query optimization on the execution.
After the AV occurs, an attempt to load the database again gives the message "database in use." A look at sysprocesses shows no associated spids.
