You need to make small modifications in the way use define the interval. One possibility is to use structure like the following:

SQL

DECLARE @intervaltype int;
DECLARE @datetouse date

SET @datetouse = GETDATE()
SET @intervaltype = 1;
--SET @intervaltype = 2;

SELECT CASE @intervaltype
          WHEN 1 THEN DATEADD( day, 7, @datetouse)
          WHEN 2 THEN DATEADD( month, 7, @datetouse)
       END

In the real situation you would replace the variable with some columns from some table.

Try:

SQL

SELECT
   CASE WHEN table.date_i = '1' or table.date_i = '4' THEN DATEADD( dd, 7 , current_timestamp)
        ELSE DATEADD( mm, 7 , current_timestamp)
   END AS Col
FROM table

Doubt if it'll be exactly what you want - but your "SQL" is seriously odd, so I can;t work out exactly what you are trying to do...
