You develop three Microsoft SQL Server 2012 databases named Database1, Database2, and Database3. You have permissions on both Database1 and Database2.
You plan to write and deploy a stored procedure named dbo.usp_InsertEvent in Database3. dbo.usp_InsertEvent must execute other stored procedures in the other databases.
