编写数据库用户级别权限的脚本

Question

我试图搜索这个并且能够找到很少但找不到确切的方法来编写数据库的数据库级别权限。

我正在迁移这个数据库，我可以使用创建其登录名sp_help_revlogin，但不会复制用户权限。

我可以使用以下查询提取权限：

SELECT
   ISNULL(OBJECT_NAME(major_id),'') [Objects], USER_NAME(grantee_principal_id) as [UserName], permission_name as [PermissionName]
FROM
    sys.database_permissions p
WHERE grantee_principal_id>0
ORDER BY
    OBJECT_NAME(major_id), USER_NAME(grantee_principal_id), permission_name

但是我需要像 rev login 这样的东西来生成一个脚本，你可以执行来获取权限映射。

我尝试过 DBAtools，但我无法使用，因为它失败并出现错误

无法找到类型 [DbaInstanceParameter]

我有 50 多个登录名和大约 20 个要复制的角色。

我一直使用Script DB Level Permissions v3（由 S. Kusen 提供）来完成您的要求。确保在要从中获取权限的数据库上下文中执行：

DECLARE 
    @sql VARCHAR(2048)
    ,@sort INT 

DECLARE tmp CURSOR FOR
