From db7edfed17efe6bc3684b0fbacc0b0249e4f0fa2 Mon Sep 17 00:00:00 2001 From: Michael Widenius Date: Wed, 29 Jun 2016 09:14:22 +0200 Subject: MDEV-7563 Support CHECK constraint as in (or close to) SQL Standard MDEV-10134 Add full support for DEFAULT - Added support for using tables with MySQL 5.7 virtual fields, including MySQL 5.7 syntax - Better error messages also for old cases - CREATE ... SELECT now also updates timestamp columns - Blob can now have default values - Added new system variable "check_constraint_checks", to turn of CHECK constraint checking if needed. - Removed some engine independent tests in suite vcol to only test myisam - Moved some tests from 'include' to 't'. Should some day be done for all tests. - FRM version increased to 11 if one uses virtual fields or constraints - Changed to use a bitmap to check if a field has got a value, instead of setting HAS_EXPLICIT_VALUE bit in field flags - Expressions can now be up to 65K in total - Ensure we are not refering to uninitialized fields when handling virtual fields or defaults - Changed check_vcol_func_processor() to return a bitmap of used types - Had to change some functions that calculated cached value in fix_fields to do this in val() or getdate() instead. - store_now_in_TIME() now takes a THD argument - fill_record() now updates default values - Add a lookahead for NOT NULL, to be able to handle DEFAULT 1+1 NOT NULL - Automatically generate a name for constraints that doesn't have a name - Added support for ALTER TABLE DROP CONSTRAINT - Ensure that partition functions register virtual fields used. This fixes some bugs when using virtual fields in a partitioning function --- sql/sql_const.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'sql/sql_const.h') diff --git a/sql/sql_const.h b/sql/sql_const.h index 31ee4603dc9..c8e60305eab 100644 --- a/sql/sql_const.h +++ b/sql/sql_const.h @@ -101,6 +101,8 @@ #define DISK_BUFFER_SIZE (uint) (IO_SIZE*16) /* Size of diskbuffer */ #define FRM_VER_TRUE_VARCHAR (FRM_VER+4) /* 10 */ +#define FRM_VER_EXPRESSSIONS (FRM_VER+5) /* 11 */ +#define FRM_VER_CURRENT FRM_VER_EXPRESSSIONS /*************************************************************************** Configuration parameters -- cgit v1.2.1
