Set database name dynamically in SQL Server stored procedure?

Question

How do I set the database name dynamically in a SQL Server stored procedure?

Answer 1

This is not dynamic SQL and works for stored procs

Declare @ThreePartName varchar (1000)
Declare @DatabaseNameParameter varchar (100)

SET @DatabaseNameParameter = 'MyOtherDB'

SET @ThreePartName = @DatabaseNameParameter + '.Schema.MyOtherSP'

EXEC @ThreePartName @p1, @p2...   --Look! No brackets
