-- ========================================
-- 修复 pid=0 问题并添加外键约束
-- ========================================
-- 步骤 1: 将所有 pid=0 的记录改为 NULL(表示顶级分组)
UPDATE evaluation_point_groups
SET pid = NULL
WHERE pid = 0;
-- 验证修改结果
SELECT COUNT(*) as "顶级分组数量(pid为NULL"
FROM evaluation_point_groups
WHERE pid IS NULL;
-- 步骤 2: 添加外键约束
-- 2.1 为 evaluation_points 表添加外键约束
ALTER TABLE evaluation_points
ADD CONSTRAINT fk_evaluation_points_group
FOREIGN KEY (evaluation_point_groups_id)
REFERENCES evaluation_point_groups(id)
ON DELETE SET NULL -- 删除分组时,将评查点的分组ID设为NULL
ON UPDATE CASCADE; -- 更新分组ID时,级联更新
-- 2.2 为 evaluation_point_groups 表添加自引用外键约束
-- pid 引用同一个表的 id(父子关系)
-- NULL 值表示顶级分组,不受外键约束限制
ALTER TABLE evaluation_point_groups
ADD CONSTRAINT fk_evaluation_point_groups_parent
FOREIGN KEY (pid)
REFERENCES evaluation_point_groups(id)
ON DELETE CASCADE -- 删除父分组时,级联删除子分组
ON UPDATE CASCADE; -- 更新父分组ID时,级联更新
-- 添加注释
COMMENT ON CONSTRAINT fk_evaluation_points_group ON evaluation_points IS '评查点所属分组外键约束';
COMMENT ON CONSTRAINT fk_evaluation_point_groups_parent ON evaluation_point_groups IS '评查点分组父子关系自引用外键约束(pid=NULL表示顶级分组)';
-- 步骤 3: 验证外键约束是否创建成功
