sql server 跨數據庫調用存儲過程

A庫存儲過程：

create PROCEDURE [dbo].[spAAAForTest]
(                        
    @UserName   nvarchar(20) =null ,
    @LoginPwd nvarchar(60)  =null
)
AS
BEGIN
    select N'A' AS a
    , N'B' AS B
    , N'C' AS C
        ;

END

 

同一臺服務器實例，A，B兩個數據庫， 在B庫的存儲過程當中，調用A庫的存儲過程

B庫：

ALTER PROCEDURE [dbo].[spAAAForTest2]
(                        
    @UserName   nvarchar(20) =null ,
    @LoginPwd nvarchar(60)  =null
)
AS
BEGIN
   declare @sql nvarchar(500);
   set @sql = N' exec DB_A.dbo.spAAAForTest ';
    exec  sp_executesql @sql

END

A，B兩個數據庫，不在同一臺服務器實例， 在B庫的存儲過程當中，調用A庫的存儲過程

B庫：

ALTER PROCEDURE [dbo].[spAAAForTest2]
(                        
    @UserName   nvarchar(20) =null ,
    @LoginPwd   nvarchar(60)  =null
)
AS
BEGIN
   declare @sql nvarchar(500);

   set @sql = N' exec OPENDATASOURCE(''SQLOLEDB'',''Data Source=SERVER-123\MSSQL2008R2;User ID=sa;Password=sa'').DB_A.dbo.spAAAForTest ';

   exec  sp_executesql @sql

END

 

 

--------------- 在跨服務器調用時，所使用OPENDATASOURCE 遭遇以下信息時

消息 15281，級別 16，狀態 1，第 1 行

SQL Server blocked access to STATEMENT 'OpenRowset/OpenDatasource' of component 'Ad Hoc Distributed Queries'

because this component is turned off as part of the security configuration for this server.

A system administrator can enable the use of 'Ad Hoc Distributed Queries' by using sp_configure.

For more information about enabling 'Ad Hoc Distributed Queries',

see "Surface Area Configuration" in SQL Server Books Online.

 

經過以下方式進行設置：

exec sp_configure 'show advanced options',1
reconfigure
exec sp_configure 'Ad Hoc Distributed Queries',1
reconfigure
