解析sql报错

[r1005410078]

正常运行

  db.Table("roles").
		Select("id", "name", "description", "GROUP_CONCAT(permission_id) as permission_ids").
		Joins("LEFT JOIN roles_permission ON roles.id = roles_permission.role_id").
		Where("name='xxx'").  // 或者 Where(fmt.Sprintf("name='%s'", "xxx")).
		First(&results)

使用 Where("name=?", "xxx") 报错

  db.Table("roles").
		Select("id", "name", "description", "GROUP_CONCAT(permission_id) as permission_ids").
		Joins("LEFT JOIN roles_permission ON roles.id = roles_permission.role_id").
		Where("name=?", "xxx").
		First(&results)

打印的 sql 是可以正常运行的
SELECT id,name,description,GROUP_CONCAT(permission_id) as permission_ids FROM roles LEFT JOIN roles_permission ON roles.id = roles_permission.role_id WHERE name='xxx' ORDER BY roles.id LIMIT 1

打印的 sql 是可以正常运行的 ❌

打印的 sql 是可以在低版本的MySQL正常运行的 ✔

你的SQL里面有GROUP_CONCAT，但是却又没有GROUP BY子句，在高版本的MySQL中，MySQL严格按照标准实现了，所以你的非法SQL就报错了。

你可以看MySQL官方的文档解释：https://dev.mysql.com/doc/refman/8.4/en/group-by-handling.html

另外的是，GORM只是一个SQL Client，有关SQL Server的错误其实不应该报在这里。
