string
Bind data.
-
buffer_gets(optional):
integer
Sum of buffer gets over all child cursors.
-
child_latch(optional):
integer
Child latch number that is protecting the cursor. This column is obsolete and maintained for backward compatibility.
-
cluster_wait_time(optional):
integer
Cluster wait time (in microseconds).
-

-
end_of_fetch_count(optional):
integer
Number of times this cursor was fully executed since the cursor was brought into the library cache. The value of this statistic is not incremented when the cursor is partially executed, either because it failed during the execution or because only the first few rows produced by this cursor are fetched before the cursor is closed or re-executed. By definition, the value of the END_OF_FETCH_COUNT column should be less or equal to the value of the EXECUTIONS column.
