Fixed bug #8528.
Representation for single-table views was made similar to
representation for multi-table views.
view.test:
Added test case for bug #8528.
view.result:
Added test case for bug #8528. Fixed other test cases.
Added a test case for bug #8392.
sql_delete.cc:
Fixed bug #8392.
The bug caused a crash for a delete statement with ORDER BY
that explicitly referred to the modified table.
Split TABLE to TABLE and TABLE_SHARE (TABLE_SHARE is still allocated as part of table, will be fixed soon)
Created Field::make_field() and made Field_num::make_field() to call this
Added 'TABLE_SHARE->db' that points to database name; Changed all usage of table_cache_key as database name to use this instead
Changed field->table_name to point to pointer to alias. This allows us to change alias for a table by just updating one pointer.
Renamed TABLE_SHARE->real_name to table_name
Renamed TABLE->table_name to alias
Renamed TABLE_LIST->real_name to table_name
CREATE DATABASE statement used the current database instead of the
database created when checking conditions for replication.
CREATE/DROP/ALTER DATABASE statements are now replicated based on
the manipulated database.
If we have DELETE with always true WHERE clause we should not use
optimized delete_all_rows() method for tables with DELETE triggers,
because in this case we will lose side-effect of deletion.
Mostly needed for Monty for him getting notion what needed for triggers
from new .FRM format.
Things to be done:
- Right placement of trigger's invocations
- Right handling of errors in triggers (including transaction rollback)
- Support for priviliges
- Right handling of DROP/RENAME table (hope that it will be handled automatically
with merging of .TRG into .FRM file)
- Saving/restoring some information critical for trigger creation and replication
with their definitions (e.g. sql_mode, creator, ...)
- Replication
Already has some known bugs so probably not for general review.
added tests to alter table for "large" alter tables and truncates in ndbcluster
added debug printout in restart() in ndbcluster
added flag THD::transaction.on to enable/disable transaction
