CursorRecompile Event Class

The CursorRecompile event class describes cursor recompile events that occur in application programming interface (API) cursors. Cursor recompile events occur when the Microsoft SQL Server 2005 Database Engine recompiles a Transact-SQL cursor due to a schema change.

Include the CursorRecompile event class in traces that record the performance of cursors. When the CursorRecompile 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 may significantly impede performance.

CursorRecompile Event Class Data Columns
