SQL err in WIN32

on Jul 30, 2004 at 07:34 UTC ( [id://378617]=perlquestion: print w/replies, xml ) Need Help??

Robertn has asked for the wisdom of the Perl Monks concerning the following question:

Hi all, This is the error I'm getting, that I can't seem to overcome, nor determine what's causing it.
Sql() ERROR
$SqlStatement: SELECT * FROM Mailing List
$err: 1 1 "-1305"

I'm trying to pull data out of an MS Access database. There was no PERL on the machine until the other day so everything is current, as of Tuesday, and the PC is running W2K. Figured out the ODBC manager so I'm able to connect to the database (I think), but err when I do the first SELECT. And I've quintiple checked, Mailing List is the table in the Lake Alpine mdb. In trying to track down an answer, examples I've seen on the net, show a real error message rather than the -1305, So I'm wondering if I've really got everything I need installed. Aside from the win32::odbc package, I can't find an authoritative list of packages that should be installed, if you want to access, Access. I'm a victim of not knowing what I don't know as Windows is not my native environment. Any clues or hint's would be greatly appreciated, especially if you can tell me how to make the error messages appear. My humble thanks in advance.

#!/usr/bin/perl -w use strict; use lib("."); use DBI; use DB_File; use Win32::ODBC; my ($db,%Data,$SqlStatement,$err ); my($DSN) = "Lake Alpine"; if (!($db = new Win32::ODBC($DSN))){ print "Error connecting to $DSN\n"; print "Error: " . Win32::ODBC::Error() . "\n"; exit; } ($SqlStatement) = "SELECT * FROM Mailing List"; if ( $db->Sql($SqlStatement)){ $err = $db->Error; warn "Sql() ERROR\n"; warn "\t\$SqlStatement: $SqlStatement\n"; warn "\t\$err: $err\n"; $db->Close(); exit; } while( $db->FetchRow() ) { undef %Data; %Data = $db->DataHash(); print "Read a record.\n"; } $db->Close();

    Have you tried enclosing the table name in square brackets, like this:

    $SqlStatement = "SELECT * FROM [Mailing List]";

     

      Thank you, thank you, thank you. That seems to have done it. Where perchance did you come across that piece of information? I've not seen it in any of my reference books, and I've gone back to look again now that I know what to look for, and I still didn't find anything. Thanx again.

    I think you have everything you need to make the connection. Your syntax looks a little unusual to me, however, and I think the calls to your error routine is what might be giving you a problem. I changed your error statements to something that I'm more familiar with and was able to get past that part of the code. Try something like this for error checking:

    my($DSN) = "Lake Alpine"; if (!($db = new Win32::ODBC($DSN))){ die "Error connecting: " . Win32::ODBC::Error() . "\n";

    ($SqlStatement) = "SELECT * FROM Mailing List"; if ( $db->Sql($SqlStatement)){ { print "error submitting SQL statment " . $db->Error(). "\n"; }

    When I run the code with those statements, I get to the next part of the code which executes and it prints out "Read a record" over and over again. If you're going to actually want to read your data, you'll have some work to do on that part of the code. If you find you need help with that part, just come on back and ask more questions.

      Hi, I did a cut and paste of your code into the program, and while it will now fall through, I still get this error. error submitting SQL statment 1 1 "-1305"
      If your getting a message rather than -1305, then I still have a problem, probably with my setup. If your getting -1305 then I don't feel so bad, but still suspect I'm missing the error file, or still not accessing it properly.

      I've not yet written the get data part, what's there is mostly from the win32::odbc fact, as I wanted to make sure I was accessing the file, before I got heavy into code, but thanks for the offer. I'll certainly come back if I get stuck. Thanks ever so much for taking your time to help out.

        I'm glad to see that EdwardG nailed the problem for you. I wasn't pulling any errors at all, but I didn't have a space in my table name. I avoid spaces in names at all costs. Just out of curiosity I renamed my table with a space in the name and I pulled up the 1305 error. In detail it reads:

        error submitting SQL statment [-1305] [1] [0] "[Microsoft][ODBC Microsoft Access Driver] The Microsoft Jet database engine cannot find the input table or query 'CODE'. Make sure it exists and that its name is spelled correctly."

        Which points directly to my table which is named "CODE CODE". Just FYI for future reference.

    Names with embedded spaces are best avoided in the Windows environment. I've learned this from experience. Access and SQL Server have problems, and the square brackets trick is something I've used for many years, I forget where I learned it.

    Your problem seems to be solved, so I'll just comment on your use of the modules. Win32::ODBC is completely unrelated to DBI, so you would rarely if ever need to use both modules. Unless you need some special feature(s) of Win32::ODBC, I would just use DBI and DBD::ODBC, as it is more portable, you can use placeholders and bind values, and you are likely to get more help with it around here. But since you already have it working with Win32::ODBC, you can ignore that advice for now unless you want to do more work just for the sake of doing more work :)

    Also, you seem to be including DB_File for no apparent reason, (so you should be able to remove all references to it and DBI AFAICT)
