-- 价区键迁到客户：与会员等级解耦
|
||
-- 新注册默认价区键/会员等级均为「普通会员」；计价时空键回落「普通客户」
|
||
|
||
-- 1) 客户表增加价区键
|
||
ALTER TABLE `t_customer`
|
||
ADD COLUMN `PriceTierKey` VARCHAR(64) NULL COMMENT '价区键（卖价 CustomerGroupValues JSON 键）' AFTER `MemberLevelId`;
|
||
|
||
-- 2) 从原会员等级价区键回填（依赖本脚本执行前 t_member_level 仍有 PriceTierKey）
|
||
UPDATE `t_customer` c
|
||
INNER JOIN `t_member_level` ml ON ml.`Id` = c.`MemberLevelId` AND ml.`IsDeleted` = 0
|
||
SET c.`PriceTierKey` = NULLIF(TRIM(ml.`PriceTierKey`), '')
|
||
WHERE c.`IsDeleted` = 0
|
||
AND (c.`PriceTierKey` IS NULL OR TRIM(c.`PriceTierKey`) = '')
|
||
AND ml.`PriceTierKey` IS NOT NULL
|
||
AND TRIM(ml.`PriceTierKey`) <> '';
|
||
|
||
-- 3) 仍为空的主客户：默认「普通会员」（与新注册一致）
|
||
UPDATE `t_customer`
|
||
SET `PriceTierKey` = '普通会员'
|
||
WHERE `IsDeleted` = 0
|
||
AND (`ParentCustomerId` IS NULL OR `ParentCustomerId` = 0)
|
||
AND (`PriceTierKey` IS NULL OR TRIM(`PriceTierKey`) = '');
|
||
|
||
-- 4) 子客户跟随主客户价区
|
||
UPDATE `t_customer` sub
|
||
INNER JOIN `t_customer` main ON main.`Id` = sub.`ParentCustomerId` AND main.`IsDeleted` = 0
|
||
SET sub.`PriceTierKey` = main.`PriceTierKey`
|
||
WHERE sub.`IsDeleted` = 0
|
||
AND sub.`ParentCustomerId` IS NOT NULL
|
||
AND sub.`ParentCustomerId` <> 0;
|
||
|
||
-- 5) 删除会员等级上的价区键列（须在插入默认等级前执行，避免 NOT NULL 约束）
|
||
ALTER TABLE `t_member_level` DROP COLUMN `PriceTierKey`;
|
||
|
||
-- 6) 确保存在启用的「普通会员」等级（供新注册默认挂靠）
|
||
INSERT INTO `t_member_level` (
|
||
`LevelCode`, `LevelName`, `MinPoints`, `ExtraDiscountRate`, `Sort`,
|
||
`Status`, `IsDeleted`, `CreateTime`
|
||
)
|
||
SELECT '普通会员', '普通会员', 0, 0, 0, 2, 0, NOW()
|
||
FROM DUAL
|
||
WHERE NOT EXISTS (
|
||
SELECT 1 FROM `t_member_level`
|
||
WHERE `IsDeleted` = 0
|
||
AND (`LevelName` = '普通会员' OR `LevelCode` = '普通会员')
|
||
);
