I am having a performnace problem is a sql server 2008 sql. The stored procedure does a full table scan when one of the @state or @zip paramteres are used. The dba says he will not put an index on the state and zip columns since this is the only sql that uses state and zip cocde. The sql look like the following:select cs.person_id,cs.cust_id,cs.customer_name,cs.address1, cs.address2, cs.city, cs.cuct_id,z.product_name,z.product_description from customer_table cs left join view1 v1 on v1.cust_id = cs.cust_id left join(select product_id,product_name,product_description from product_table p on p.iventory_id = v.iventory_idwhere @prod_quantity <= p.supply_on_hand) z on z.person_id = c.person_id where @zip = Cs.zip or @state=cs.stateThus can you tell me what I can do to make this sql run faster? |
