in reply to identifier too long error

It would help to see not only the SQL statement, but also how exactly you embed it into Perl. I think there might be the real problem. If you print out the SQL statement Perl has right before calling prepare, does it look exactly as the one you showed ?

    given your post I decided to try embedding into variable $query and then calling prepare, thanks to the thezip I also turned on logging for dbi and have a tracefile, here is what I have so far, now it appears to execute but I don't get any results to stdout..
    ### Rewrite of reminder ### added dbi & dbd::odbc modules for debugging ### added data:dumper also for debugging ### added tracelevel and trace.txt for debugging use OLE; use DBI; use DBD::ODBC; use Mail::Sender; my $trace_level=1; my $trace_file='tracefile.txt'; DBI->trace($trace_level,$trace_file); #### lnitialization of Global Variables & Arrays #### my $debug =0; my $t = time; (my $sec, my $min, my $hour, my $mday, my $mon, my $year, my $wday +, my $yday, my $isdst)=localtime($t); $year = $year + "1900"; my $SQLServer = "servername"; my $DB = "dbname"; my $SQLUname = "username"; my $SQLpass="userpass"; my $query="SELECT ClassSchedule.EventDate AS EventDate, DATEDIFF(dd, { fn NOW() }, ClassSchedule.EventDate) AS + Until, DATEDIFF(dd, ClassRoster.Enrolled, ClassSchedule.Event +Date) AS Since, Classes.Duration AS Duration, Classes.Topic AS Topic, Classes.Description AS Description, ClassLocation.Location AS Location, ClassLocation.Address AS Address, ClassLocation.Directions AS Directions, ClassLocation.Map AS Map, ClassRoster.idEnrollee AS idEnrollee, ClassRoster.System AS System, ClassRoster.Account AS Account, ClassRoster.PublicID AS PublicID, ClassRoster.Name AS Name, ClassRoster.Email AS emailAddress FROM ClassSchedule INNER JOIN Classes ON ClassSchedule.id_Class = Classes.idClas +s INNER JOIN ClassRoster ON ClassSchedule.idEvent = ClassRoster +.id_Event INNER JOIN ClassLocation ON ClassSchedule.id_Location = Class +Location.idLocation WHERE (ClassSchedule.EventDate > { fn NOW() }) AND (ClassRoster.Cancelled IS NULL) AND (ClassRoster.Reminded IS NULL) AND (DATEDIFF(dd, ClassRoster.Enrolled, ClassSchedule. +EventDate) > 7) AND (NOT (DATEPART(dw, { fn NOW() }) IN (1, 7))) AND (DATEDIFF(dd, { fn NOW() }, ClassSchedule.EventDat +e) < 7)"; # Connect to the database # See footnote 1 my $dbh = DBI->connect("dbi:ODBC:driver=SQL Server;Server=VASVCSSQL;da +tabase=MLXhelp;uid=$SQLUname;pwd=$SQLpass;") or die "Couldn't open d +atabase: $DBI::errstr; stopped"; print "connected finally"; # Prepare the SQL query for execution my $sth=$dbh->prepare($query); $sth->execute() or die "Couldn't execute statement: $DBI::errstr; stop +ped"; $sth->finish(); $dbh->disconnect();
    finally tracefile.txt...

      It might not be the problem, but it seems that both the DBI and the DBD::ODBC you use are a bit outdated.

      Current versions are DBI-1.607 and DBD::ODBC-1.17.

      Can you give them a try ?

        will they work with 5.6.1 build 630? this is production and some of our stuff will not work if I upgrade the perl being used, I know I already tried and had to go-back to previous version.
      completely unrelated to your problem, but this:
      my $t = time; (my $sec, my $min, my $hour, my $mday, my $mon, my $year, my $wday, my + $yday, my $isdst)=localtime($t); $year = $year + "1900";

      can be replaced with:

      my $year = (localtime)[5] + 1900;

      Since you are only using the year, there is no need to declare all those extra variables.
