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。

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

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.';

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。

不幸的是，由于声誉不够，我无法评论Sean Rose的帖子，但是我不得不修改脚本的“公共”角色部分，因为它没有显示针对sys.objects的(INNER) JOIN权限。在它被更改为LEFT JOIN之后，我不得不进一步修改where子句逻辑以省略系统对象。我对公众烫发的修改查询如下。

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?

Security Audit Report
1) List all access provisioned to a sql user or windows user/group directly 
2) List all access provisioned to a sql user or windows user/group through a database or application role
3) List all access provisioned to the public role

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.
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.   
                  This value may not be populated for all roles.  Some built in roles have implicit permission
                  definitions.          
ObjectName      : Name of the object that the user/role is assigned permissions on.  
                  This value may not be populated for all roles.  Some built in roles have implicit permission
                  definitions.
ColumnName      : Name of the column of the object that the user/role is assigned permissions on. This value
                  is only populated if the object is a table, view or a table value function.
