Hi,<BR><BR>I&#039;m using a SQL Server table to store shopping cart data.<BR><BR>Each row of cart data includes an ID of the cart, a reference to a product and, if it exists, a reference to product combination.<BR><BR>Updating and inserting into the cart involves quite alot of querying in order to determine whether a product already exists in the cart, finding the product&#039;s mode of pricing and finding the correct combination of the product.<BR><BR>As a result I would like to put an index on several columns. <BR><BR>My question, is using indexes on a table which will probably get alot of hits more of a hindrance than a help?<BR><BR>Cheers,<BR><BR>I.
