The sp_iqcursorinfo procedure can be invoked without any parameters. If no parameters are specified, sp_iqcursorinfo returns information about all cursors currently open on the server. If both parameters are specified, sp_iqcursorinfo reports information about all of the cursors that have the specified name and are in the specified connection.
You must have EXECUTE privilege on the system procedure, as well as the MONITOR system privilege.
If you do not specify the first parameter, but specify the second parameter, you must substitute NULL for the omitted parameter. For example, sp_iqcursorinfo NULL, 1.
