I'm trying to add a search function to my site that will allow folks to find the ten nearest locations by zip code. I'm not trying to tap into any actual radius information. I really only wanted to add SQL that would search for the ten zip codes nearest in number to the one entered.

Does anyone have a the SQL for this?

Thanks in advance

Don't really know about US zip codes, in the UK matching by "text closeness" would return nonsense in terms of geographical location.

That said:

<%
If Request("txtZip" = "" Then
varZIP = "%" 'default value that returns all results
Else
varZIP = Replace(Request("txtZip", "'","''" 'replace those pesky single quotes
End If
%>

RecordsetName.Source = "SELECT * FROM TableName WHERE ZipCodeField LIKE '" & varZIP & "'"

NOTES:
This will find exact mathes:- LIKE '" & varZIP & "'"
This will find a match with any string containing the string varZIP:- LIKE '%" & varZIP & "%'"
This will find a match with any string starting with the string varZIP:- LIKE '%" & varZIP & "'"
This will find a match with any string ending with the string varZIP:- LIKE '" & varZIP & "%'"
