CursorUnprepare Event Class

The

event class provides information about cursor unprepare events that

occur in application programming interface (API) cursors. Cursor unprepare events occur when

the Microsoft Database Engine discards an execution plan.

Include the

event class in traces that record the performance of cursors.

When the

event class is included in a trace, the amount of overhead incurred

depends on how frequently cursors are used against the database during the trace. If cursors

are used extensively, the trace can significantly impede performance.
