SQL Help

[waynedp]

I have the following SQL statement. What I am trying to do is find the longest length address that has a zip+4. I know there may be many address that have the same length. My problem is I am getting addresses that do not have a zip+4. Any help would be greatly appreciated:

SELECT TOP 1 ADDRESS FROM waynedb ;
ORDER BY SQNCNMBR WHERE LEN(ALLTRIM(ADDRESS)) = (SELECT MIN(LEN(ALLTRIM(ADDRESS))) FROM waynedb ;
WHERE LEN(ALLTRIM(ADDRESS)) > 0 AND LEN(ALLTRIM(ZIP4)) > 9)

You have several semicolons.
I think your query raise error on your second row, because this row is treated as different query.
BTW ORDER BY can not be before WHERE clause in SQL Server:
Also, there is NO ALLTRIM() function in SQL Server.
If your ADDRESS/ZIP4 type is n/varchar then there is no need to TRIM it, they are already trimmed.
Something like that:

SELECT TOP 1 ADDRESS 
       FROM waynedb
WHERE LEN(ADDRESS) = (SELECT MAX(LEN(ADDRESS)) -- You want longest length address, right? then why you query MIN()?
                             FROM waynedb
                      WHERE LEN(ZIP4) > 9)
ORDER BY SQNCNMBR
