what is the fastest way to check if Item ID exist in the database?

Is there a way to retrieve the whole column of itemID and then query it to MSSQL2000, then display the itemIDs that does not exist.

View 2 RepliesI have written the code below to check and see if the text the user entered into the txtbox already exists as an item in a listbox before adding the new item. This works well; however, if say "Fish" exists in the listbox but the user entered "fish" in the textbox, the item is added to the listbox. I do not want this because the item already exists. How can I modify my code so that the comparison is not case sensitive?
