-- 查找并修复 sys_menu 表中重复的 path 记录

|
|
-- 第一步：查看是否有重复的 path
|
|
SELECT
|
|
path,
|
|
COUNT(*) as count,
|
|
STRING_AGG(CAST(menu_id AS TEXT), ', ') as menu_ids,
|
|
STRING_AGG(menu_name, ', ') as menu_names
|
|
FROM sys_menu
|
|
GROUP BY path
|
|
HAVING COUNT(*) > 1;
|
|
|
|
-- 第二步：查看具体重复记录的详细信息
|
|
-- (替换下面的重复路径值)
|
|
-- SELECT * FROM sys_menu WHERE path = 'your_duplicate_path_value' ORDER BY menu_id;
|
|
|
|
-- 第三步：自动删除重复的 path 记录（保留 menu_id 最小的）
|
|
DELETE FROM sys_menu
|
|
WHERE menu_id IN (
|
|
SELECT menu_id FROM (
|
|
SELECT menu_id,
|
|
ROW_NUMBER() OVER (PARTITION BY path ORDER BY menu_id) as rn
|
|
FROM sys_menu
|
|
) t
|
|
WHERE rn > 1
|
|
);
|
|
|
|
-- 第四步：验证是否还有重复的 path
|
|
SELECT
|
|
path,
|
|
COUNT(*) as count
|
|
FROM sys_menu
|
|
GROUP BY path
|

HAVING COUNT(*) > 1;
