Stored procedure scope: using sp from another database

Question

Good day,
I hava a stored procedure named sp_emps (simple select from an employees table) in a database named Employees.
I would like use this procedure in a another database named New_Employees.
Is this possible, without creating / copying the sp to the other database ?
Also I did not want to make the sp a system object
Please assist

Hi Zimiso,
The problem here is that no matter from where you execute your procedure, its context will always be the "Employees" database.
What you ask for is possible, but only by using Dynamic SQL.
You can have a @Database parameter on your procedure, and then concatenate the value in this parameter to wherever needed in your dynamic queries.
For example:
CREATE PROCEDURE sp_emps
@Database NVARCHAR(200)
AS
DECLARE @Command NVARCHAR(MAX);
SET @Command = 'SELECT * FROM ' + QUOTENAME(@Database) + '.dbo.MyEmployees'EXECUTE(@Command)
More information about dynamic SQL:

This isn't an ideal solution because there are lots of possible risks and problems that come along with dynamic SQL (for example, SQL Injection).
The better solution, in my opinion, would be to create the stored procedure as a system object (create it in the "master" database). This will make its context change based on the database from whence it was executed.
