[转] sql server 跨数据库调用存储过程

A库存储过程：

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

同一台服务器实例，A，B两个数据库， 在B库的存储过程中，调用A库的存储过程

B库：

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

 

A，B两个数据库，不在同一台服务器实例， 在B库的存储过程中，调用A库的存储过程

B库：

ALTER PROCEDURE [dbo].[spAAAForTest2]
(                        @UserName   nvarchar(20) =null ,@LoginPwd   nvarchar(60)  =null
)
AS
BEGINdeclare @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 @sqlEND

 

 

 

--------------- 在跨服务器调用时，所使用OPENDATASOURCE 遭遇如下信息时

消息 15281，级别 16，状态 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.

 

通过如下方式进行设置：

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