    If i try to run the next script:

    use DBI;
    use infotarif::infotarif;
    use strict;
    do '';
    my ( $dbh, $dbh1, $qsitios, $compresult, $site, $company, $desc );

    $dbh = DBI->connect($cfginfotarif::mydbdata,$cfginfotarif::dbusername,$cfginfotarif::dbpassword) or die "Cannot connect to '$cfginfotarif::mydbdata'" ;

    $qsitios = $dbh->prepare ("SELECT SITIO FROM SITIOS") or die "Cannot SELECT from SITIOS ";
    $qsitios -> execute  or die "Cannot execute SELECT from SITIOS";
    $qsitios -> bind_columns(undef, \$site);

    while( $qsitios -> fetchrow_arrayref )
        $compresult = $dbh->prepare ("SELECT COMP, DESCCOMP FROM COMPANIAS") or die "Cannot SELECT from COMPANIAS ";
        $compresult -> execute  or die "Cannot execute SELECT from COMPANIAS";
        $compresult -> bind_columns(undef, \$company, \$desc);

        while( $compresult -> fetchrow_arrayref )
            print "Company: $company, $desc\n";
        $compresult -> finish();
    $qsitios -> finish();

    and i run perl it works fine but if i run:
    perl -w it works too but i have the next error message:

    DBD::InterBase::st fetchrow_arrayref failed: Unknown cursor
    -Dynamic SQL Error
    -SQL error code = -504
    -Cursor unknown
    DBD::InterBase::st finish failed: The cursor identified in a FETCH or CLOSE statement is not open.
    -Dynamic SQL Error
    -SQL error code = -501
    -Attempt to reclose a closed cursor
    DBI handle cleared whilst still active.
        dbih_clearcom (sth 0x19bdd20 0x0, com 0x19c691c, imp DBD::InterBase::st):
           FLAGS 0x115: COMSET Active Warn PrintError
           PARENT DBI::db=HASH(0x19bd62c)
           KIDS 0 (0 Active)
           IMP_DATA undef
           NUM_OF_FIELDS 1
           NUM_OF_PARAMS 0

    If i use two conections i do not get any error but what i know is that with DBI i can do many queries at the same time using the same connection.

    I am using activestate perl 5.82, DBI 1.39 and firebird 1.03.

    Thank you very much in advance for your help.

      You have nested statement handles, so you should turn AutoCommit off or use ib_softcommit attribute instead.
      This topic is already covered in DBD::InterBase::FAQ.
