I want to substring to get position 13 to the position just before the first semi-colon.

The string is
Data Source=edwdev02; User Name=med_query_user; Server=codenamed;

I want to end up with edwdev02

So something like
Select substring(my_variable,13,instring_position(my_variable,';') - 1)
From such_and_such
Where this_and_that

   CASE WHEN  charindex(';',my_variable, 13)  > 0  
            THEN substring(my_variable,13,charindex(';',my_variable, 13) - 13)
             ELSE  NULL

From such_and_such
Where this_and_that
