-query_limit(n)
-
- sets a limit on the maximum numbers of query returned from
- a backend. It can be used to limit the result size retrieved
- by the application for poor input data or to avoid accidental
- table product while playying with sql.
-
backend_pid()
return the pid of our corresponding backend.
min(x,y)
max(x,y)
- return the min or max bteween two integers.
-
-assert_enable(bool)
-
- enable/disable assert checkings in the backend, if it has been
- compiled with USE_ASSERT_CHECKING.
-
-assert_test(bool)
-
- test the assert enable/disable code, if the backend has been
- compiled with ASSERT_CHECKING_TEST.
