我看到的其他答案遗漏了数据库中可能存在的一些权限。下面代码中的第一个查询将获得非系统对象的数据库级权限。它还生成适当的GRANT语句。第二个查询获取所有角色成员。

这必须为每个数据库运行，但是太长了，不能用于sp_MSforeachdb。如果要这样做，就必须将它作为系统存储过程添加到主数据库中。

为了涵盖所有可能性，还必须有一个检查服务器级权限的脚本。

从SQL Server 2005开始，您可以使用系统视图来实现这一点。例如，这个查询列出了数据库中的所有用户及其权限:

select  princ.name
,       princ.type_desc
,       perm.permission_name
,       perm.state_desc
,       perm.class_desc
,       object_name(perm.major_id)
from    sys.database_principals princ
left join
        sys.database_permissions perm
on      perm.grantee_principal_id = princ.principal_id

请注意，用户也可以通过角色拥有权限。例如，db_data_reader角色授予对大多数对象的选择权限。

一个简单的查询，只显示你是否是系统管理员:

IF IS_SRVROLEMEMBER ('sysadmin') = 1  
   print 'Current user''s login is a member of the sysadmin role'  
ELSE IF IS_SRVROLEMEMBER ('sysadmin') = 0  
   print 'Current user''s login is NOT a member of the sysadmin role'  
ELSE IF IS_SRVROLEMEMBER ('sysadmin') IS NULL  
   print 'ERROR: The server role specified is not valid.';

以下是我的版本，改编自他人。我刚刚花了30分钟来回忆我是怎么想到这个的，@杰里米的回答似乎是我的核心灵感。我不想更新杰里米的答案，以防我引入错误，所以我在这里发布了我的版本。

我建议将完整脚本与Kenneth Fisher的《T-SQL Tuesday:特定用户拥有什么权限?》:这将允许你自底向上回答合规/审计问题，而不是自顶向下。

EXECUTE AS LOGIN = '<loginname>'

SELECT token.name AS GroupNames
FROM sys.login_token token
JOIN sys.server_principals grp
    ON token.sid = grp.sid
WHERE token.[type] = 'WINDOWS GROUP'
  AND grp.[type] = 'G'

REVERT

To understand what this covers, consider Contoso\DB_AdventureWorks_Accounting Windows AD Group with member Contoso\John.Doe. John.Doe authenticates to AdventureWorks via server_principal Contoso\DB_AdventureWorks_Logins Windows AD Group. If someone asks you, "What permissions does John.Doe have?", you cannot answer that question with just the below script. You need to then iterate through each row returned by the below script and join it to the above script. (You may also need to normalize for stale name values via looking up the SID in your Active Directory provider.)

下面是脚本，没有包含这种反向查找逻辑。

Columns Returned:
UserName         : SQL or Windows/Active Directory user account.  This could also be an Active Directory group.
UserType         : Value will be either 'SQL User' or 'Windows User'.  This reflects the type of user defined for the 
                  SQL Server user account.
PrinciaplUserName: if UserName is not blank, then UserName else DatabaseUserName
PrincipalType    : Possible values are 'SQL User', 'Windows User', 'Database Role', 'Windows Group'
DatabaseUserName : Name of the associated user as defined in the database user account.  The database user may not be the
                   same as the server user.
Role             : The role name.  This will be null if the associated permissions to the object are defined at directly
                   on the user account, otherwise this will be the name of the role that the user is a member of.
PermissionType   : Type of permissions the user/role has on an object. Examples could include CONNECT, EXECUTE, SELECT
                   DELETE, INSERT, ALTER, CONTROL, TAKE OWNERSHIP, VIEW DEFINITION, etc.
                   This value may not be populated for all roles.  Some built in roles have implicit permission
                   definitions.
PermissionState  : Reflects the state of the permission type, examples could include GRANT, DENY, etc.
                   This value may not be populated for all roles.  Some built in roles have implicit permission
                   definitions.
ObjectType       : Type of object the user/role is assigned permissions on.  Examples could include USER_TABLE, 
                   SQL_SCALAR_FUNCTION, SQL_INLINE_TABLE_VALUED_FUNCTION, SQL_STORED_PROCEDURE, VIEW, etc.

                   definitions.
ColumnName       : Name of the column of the object that the user/role is assigned permissions on. This value

我尝试了几乎所有这些功能，但很快就注意到缺少一些功能，尤其是系统管理员用户。在我们即将进行的审计中，有这样一个洞会很不好看，所以我想出了这个

USE master
GO

SELECT DISTINCT 
        p.name AS [loginname] ,
        --p.type,
        p.type_desc ,
        p.is_disabled,
        s.sysadmin,
        sp.permission_name
FROM sys.server_principals p
INNER JOIN sys.syslogins s ON p.sid = s.sid
INNER JOIN sys.server_permissions sp ON p.principal_id = sp.grantee_principal_id
WHERE p.type_desc IN ('SQL_LOGIN', 'WINDOWS_LOGIN', 'WINDOWS_GROUP')
    -- Logins that are not process logins
    AND p.name NOT LIKE '##%'
ORDER BY p.name
GO

下面是Jeremy提交的最受欢迎的答案，但经过修改，包含了Greg Sipes提到的系统管理员和禁用标志以及log_date_time列。

两全其美?
