    Question Using Multiple Fields in Form to Generate Query

    Right now I have just one table in Access which holds different information for colleges. Some of the fields include the tuition and the state in which it is located. I created a form off of this table that allows me to select any criteria of those fields and run a query to get the related results. For example, I can search by schools in New York that cost 30k and get a list of all associated colleges. I do this by creating a query and having the criteria equal whatever value was selected in the form for both of those properties.



    However, I need some guidance in setting up how to do the same filter of only one of the fields is filled in. So if I want to not select a state but get all schools costing 30k, how can I do that. The only way I can get it to work is selecting a value for both fields. By leaving one blank my query does not return anything. Eventually this will expand to have four or five filters so I would use this knowledge to do same setup if 1,2,3,4 or all 5 filters are used.

    Thanks for any help, if you have any questions let me know.

    How are you using the search form? Is the criteria in the qry? Do you a default value for the fields on your search form? See this post.

    It sounds like you would need code to check each control, determine if it is used, if so, add it to the Sql,

    if not isnull(txtName1) then vFilter = VFilter & [Name]='" & txtName & "'"
    if not isnull(cboState2) then vFilter = VFilter & [State]='" & cboState2 & "'"
    if len(vFilter)>0 then vFilter = " WHERE " & vFilter
    sSql = sSql & vFilter
    until finally docmd.openSQL sSql

    you can use like "*" & [forms]![formname]![fieldname] & "*" as your criteria, this basically creates a wildcard search for any non populated value.

Please reply to this thread with any new information or opinions.
