Run Stored Procedure From Another Database in Current Database - sql-server-2008

Question

I have one shared database and multiple client databases. The data is stored in the client database. We want to create a master set of stored procedures in the shared database and execute them from the client database. Given the following:
use shared;
go
create procedure GetInvoices as
print db_name() ' <- current database'
select * from invoices
go
use client1;
create table invoices(...columns...)
exec shared.dbo.GetInvoices
This returns the following error:
shared <- current database
Msg 208, Level 16, State 1, Procedure GetInvoices, Line 3
Invalid object name 'invoices'.
Without using dynamic SQL, how can I run the stored procedure in shared from client1 so that it executes in client1 and thus has access to all of the tables in client1?

Answer 1

You can run a stored procedure defined in master database in context of client1 database and see all client1 database tables, without dynamic SQL, but it uses undocumented stored procedure sp_ms_marksystemobject.
Your stored procedure name must start with sp_, for example sp_GetInvoices. Create it in master database, then call exec sp_ms_marksystemobject sp_GetInvoices to make it see the tables of the current database.
USE master
GO
CREATE OR ALTER PROCEDURE sp_GetInvoices
AS
BEGIN
SELECT ClientName from Invoice
END
GO
exec sp_ms_marksystemobject sp_GetInvoices
USE client1
GO
create table Invoice (ClientName varchar(100))
insert Invoice select 'Acme Client'
exec sp_GetInvoices
Result (running on SQL Server version 13.0.5081.1):
ClientName
------------
Acme Client

Try this on your "Master" database:
CREATE PROCEDURE [dbo].[GetDataFromClient]
#DB VARCHAR(50)
AS
BEGIN
SET NOCOUNT ON;
DECLARE #STMT VARCHAR( 300 );
DECLARE #SP VARCHAR( 500 );
SET #SP = 'dbo.GetData';
SET #STMT = 'EXEC(''' + #SP + ''')';
EXEC('USE '+ #db + ';' + #STMT)
END
Now on the "Client" database:
CREATE TABLE [dbo].[TestClient](
[ID] [int] NOT NULL,
[Description] [varchar](10) NULL,
CONSTRAINT [PK_Test] PRIMARY KEY CLUSTERED
(
[ID] ASC
) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY].
Create the stored procedure to retrieve data from table TestClient
CREATE PROCEDURE [dbo].[GetData]
AS
BEGIN
SELECT *
FROM TestClient;
END
Now you can retrieve the columns from the TestClient Database using:
USE [TestMaster]
GO
DECLARE #return_value int
EXEC #return_value = [dbo].[GetDataFromClient]
#DB = N'TESTCLIENT'
SELECT 'Return Value' = #return_value
GO

You can call stored procedure using four part name after creating link server.
Or it can be called by openquery option.
LinkSerevr:
EXEC [ServerName] .dbname.scheme.StoredProcedureName
openquery : SELECT * FROM
OPENQUERY( [ServerName] .dbname.scheme.StoredProcedureName)
