Collect all tables and SPs refered by a statement, and open all tables
with an implicit LOCK TABLES. Do find things refered by triggers and views,
we open them first (and then repeat this until nothing new is found), before
doing the actual lock tables.
Version for 5.0. Committed for merge.
If the result table is one of the select tables in INSERT SELECT,
we must not disable the result tables indexes before selecting.
Now the preparation is split into two prepare methods.
The first detects the situation and defers some preparations
until the second phase.
Bug #6284 - report truncation warnings in INSERT ... SELECT only for "INSERT" part
sql/sql_insert.cc
Bug #6284 - report truncation warnings in INSERT ... SELECT only for "INSERT" part
insertion of new records partially failed. It would get logged because of the
logic to log a partially-failed 'INSERT ... SELECT' (which can't be rolled back
in non-transactional tables), but 'CREATE TABLE ... SELECT' is always rolled
back on failure, even for non-transactional tables. (Bug #6682)
(Original fix reimplemented after review by Serg and Guilhem.)
- ndb_use_exact_count
- ndb_autoincrement_prefetch_sz
- ndb_use_transactions
- ndb_force_send
moved "inlined" functions to .cc file since they are virtual anyways
enabled printout od ndb errors in warnings even if mapping existst to mysql error code
Added push_back(void *, MEM_ROOT *) to make some list-handling code easier that needs to be allocated in a different mem-root
(Before one had to change thd->mem_root ; push_back(); restore mem_root.
Now thd->mem_root is a pointer to thd->main_mem_root and THR_MALLOC is a pointer to thd->mem_root.
This gives us the following benefits:
- Allow us to easily detect if arena has already been swapped before (this fixes a bug in setup_conds() where arena was swaped twice in some cases)
- Faster swaps of arenas (as we don't have to copy the whole MEM_ROOT)
- We don't anymore have to call my_pthread_setspecific_ptr(THR_MALLOC,...) to change where memory is alloced. Now it's enough to set thd->mem_root
FOUND is not a reserved keyword anymore
Added Item_field::set_no_const_sub() to be able to mark fields that can't be substituted
Added 'simple_select' method to be able to quickly determinate if a select_result is a normal SELECT
Note that the 5.0 tree is not yet up to date: Sanja will have to fix multi-update-locks for this merge to be complete
positive numbers when no resultset is available": when sending
result set metadata we need to use virtual select_result::send_fields,
and not address protocol directly, because select_result descendents may
intercept result set (it's the case for example for SELECT INTO OUTFILE).
