Calculate sum data and insert into another in SQL

I need to calculate sum of hours based on period column and insert into another table. Please see below example data. [code]

tbl_Summary

    Client_id   Store_id    attribute1  Period    Hours     attributes
1              16             1        2/25/2007  1054.8     1

Out put table will be like this.

tbl_history
--------------
[code]client_id store_id    attribute1  hours   attributes
1                    16          1         8521.92    1
1                    18          1        11196.92    1

Conditions for sp

1. Parameters to sp are only @client_id, @attribute1, @attributes

2. Find Max(Period) and go back to 52 weeks and calculate Sum(Hours) where Store_id= ? (in example 16 and 18 or each store_id) and client_id= @client_id and attribute1 = @attribute1 and attributes = @attributes. ie. Sum(Hours) will change based on store_id and when store_id will change period will change. See side moved data

store_id = 16 and period=9/20/2009 t开发者_如何学Goo 9/20/2009 sum(hours) =8521.92

1. Insert into another table all output tbl_history.

Please give me solution. If you have any question ask me.

Thanks in advance

INSERT INTO tbl_history
SELECT client_id, store_id, attribute1, SUM(Hours), attributes
FROM tbl_Summary
WHERE PERIOD <=
(
    SELECT MAX(PERIOD)
    FROM tbl_Summary
    WHERE client_id = @client_id
    AND attribute1 = @attribute1
    AND attributes = @attributes
)
AND PERIOD  >= 
(
    SELECT (MAX(PERIOD) - 1 year) --(I dont remember the sintax for sql getdate() something but thats the idea)
    FROM tbl_Summary
    WHERE client_id = @client_id
    AND attribute1 = @attribute1
    AND attributes = @attributes
)
AND client_id = @client_id
AND attribute1 = @attribute1
AND attributes = @attributes
GROUP BY client_id, store_id, attribute1, attributes

Try it and tell me if it worked.

Regards.
