Hi,
I currently have two DB's (DB1 and DB2) setup on an instance of SQL server. DB2 is essentially a reporting store which I populate with data from DB1

Currently: my Extract script takes the following parameters:
@sourceDatabase sysname, @YearMonthStart int, @YearMonthEnd int


Within the script I list a number of tables to be populated based on these parameters.
INSERT INTO TableX
EXEC ('USE '+ @sourceDatabase + ' EXEC spPopulateTableX')



I am now migrating DB2 to new server and the two servers are setup as linked servers.
So I cannot use 'USE' anmore.

So essentially my questions is how do a reference the source database in my script?

All help is appreciated.

Try this: EXEC database.schema.procedureName

If your database is called Reports, and your procedure is dbo.InventorySummary you would use:

EXEC Reports.dbo.InventorySummary.

Thanks Bob that works for me.

A bit off topic...in order to execute the storedProcs on the DB1 the linked server needs to be configured to allow remote procedure calls.
Is this a good practice security wise?
Should I perhaps look at ways to get the data without executing the storeprocs on the DB1.

It creates yet another vulnerability, if you don't maintain control over who is allowed to execute which stored procedures. Someone more DBA focused could give you a better answer than I can.
