Need Help for SQL Subqueries

Question

Hi,
I want to generate material wise stock report.
Report must contain the following
CNT_DESC TOTAL_BAGS TOTAL_WEIGHT
I am getting the correct result. But i have a doubt. Is there any other efficient or optimal query for solving this?
The followings are the query to retrieve data.
SELECT CT.cnt_count,
       NVL(
                  SELECT SUM(lvyp_weight)
               FROM tb_lvm_yarnprod
               WHERE lvyp_deleted= 'N'
               AND lvyp_countno = CT.cnt_seqno

            0

TOTAL_WEIGHT = (PRODBAGS + PURBAGS + SALERETBAGS + RETKNITBAGS) - (SALEBAGS + ISSBAGS)
Will it get slow, while data gets increased? Is there any other efficient way for solving the above?
Thanks & Regards
