--TEST--
|
||||
Test a batch query with different cursor types
|
||||
--DESCRIPTION--
|
||||
Verifies that batch queries don't work with dynamic, static, and keyset
|
||||
server-side cursors, and checks that correct column and row counts are
|
||||
returned otherwise. For information on the expected behaviour of cursors
|
||||
with batch queries, see
|
||||
