Question

perl loop

Asked by: oleggold

I need example of perl script looping through values in a table and assembling acccess mdb files names from that loop and doing follwing inside the loop:
0.unzipping md files in zip
1.opening md files
2. updating a record
3.closing db
4.zipping md files in zip
Here's following code,I may need just to modify it,most parts I've found have a trouble with those 4 commands and how to use values I receive in my sql

use Win32::ODBC;
 
# start  wzunzip vars.
my ($start_unzip_time,$end_unzip_time);
my $WINUNZIP_TIMEOUT=240; # seconds time out for autowinzip
my $winunzip_process_time;
my $winunzip_kicked_off;# controls wzunzip call
my $WINUNZIP_COMMAND='C:\\Program Files\\WinZip\\wzunzip';
 
my $UnZipFile;
my $TempUnZipFolder;
my $long_zip_database_filename = "Long ZIP Database Name.txt"; # long zip filenames for test database
 
$DriverType = "Microsoft Access Driver (*.mdb)";
$DSN = "MS Access Database TMP";
$Dir = 'C:\Program Files\Perl Express\test';
$uid = "";
$password = '';
$DBTable = 0;
 
# Configures temporary DSN
Win32::ODBC::ConfigDSN(ODBC_ADD_DSN, $DriverType,
                       ("DSN=$DSN",
                        "Description=Win32 ODBC Test DSN for Perl",
                        "DBQ=$Dir\\$DBase",
                        "DEFAULTDIR=$Dir",
                        "UID=$uid", "PWD=$password")) or
                             die "ConfigDSN(): Could not add temporary DSN".Win32::ODBC::Error();
 
$db = new Win32::ODBC($DSN) or die "Connect to database failed.\nError: ".Win32::ODBC::Error()."\n";
 
# Prints data from the table No. $DBTable
&PrintDatabase($db);
 
# Remove temporary DSN
Win32::ODBC::ConfigDSN(ODBC_REMOVE_DSN, $DriverType, "DSN=$DSN") or
die "ConfigDSN(): Could not remove temporary DSN because ".Win32::ODBC::Error();
 
sub PrintDatabase {
my $db = shift(@_);
#my @table = $db->TableList;
my @column;
my $column;
@column = $db->FieldNames();
 
printf("%15.15s ", $_) for @column;
print "\n";
printf("%15.15s ", "_" x 15) for @column;
print "\n";
 
  while($db->FetchRow()) {
  my %Data = $db->DataHash();
  defined($Data{$_}) ? printf("%15.15s ", $Data{$_}) : printf("%15.15s ", "") for @column;
  print "\n";
  }
 
print "\n";
}
 
$db->Close();

seems that my probem is to assign the hash value from data hash into some array

printf("%15.15s ", $_) for $column;
print "\n";
printf("%15.15s ", "_" x 15) for $column;
 
print "\n";
 
  while($db->FetchRow()) {
  my %Data = $db->DataHash();
  #   defined($Data{$_}) ? printf("%15.15s ", $Data{$_}) : printf("%15.15s ", "") for $column[3];
#  defined($Data{$_}) ? printf("%15.15s ", $Data{$_}) : printf("%15.15s ", "") for @column;
  #
 
  my $dbname =$Data{$_};
   defined($Data{$_}) ? printf("%15.15s ",$dbname[0])  : printf("%15.15s ", "") for $column[3]  ;
  printf("%15.15s ", @dbname) ;
  print "\n";
  }
print "\n";
}
 
$db->Close();

oleggold: You've posted this in 2 of the Microsoft Access zones, along with one Perl zone. You might use the Request Attention link to ask the mods to move this to more appropriate zones. While there are certainly a few Access Experts who know Perl, you'll get a LOT better responses if you place this in the web-oriented zones.

Good Luck!!

ok,so how can I change the zones?

should I just delete the question and post a new one?
