Fixed amount of memory, in bytes, used for the lifetime of this child
cursor

NUMBER
Fixed amount of memory required during the execution of this child
cursor
SORTS
NUMBER
The number of sorts that was done for this child cursor
LOADED_VERSIONS
NUMBER
1 if context heap is loaded, 0 otherwise
OPEN_VERSIONS
NUMBER
1 if the child cursor is locked, 0 otherwise

NUMBER
The number of users executing the statement
EXECUTIONS
NUMBER
The number of executions that took place on this object since it was
brought into the library cache
