MSSQL查询每个账号在每个数据库里的角色名（供参考）

mssql_login_role_in_each_db.sql

-- 查询所有登录名在 SQL Server 实例级别的角色
SELECT 
    sp.name AS LoginName,
    sp.type_desc AS LoginType,
    sp.default_database_name AS DefaultDatabase,
    sp.default_language_name AS DefaultLanguage,
    sp.create_date AS CreateDate,
    server_role.name AS ServerRole
FROM sys.server_principals AS sp
LEFT JOIN sys.server_role_members AS srm
    ON sp.principal_id = srm.member_principal_id
LEFT JOIN sys.server_principals AS server_role
    ON srm.role_principal_id = server_role.principal_id
WHERE sp.type IN ('U', 'G', 'S', 'A'); -- 这将包括 SQL Server 账户、Windows AD 组、服务账户和匿名登录

-- 注意：如果需要过滤特定角色，请根据需要修改 WHERE 子句。
