Hi All, I'm trying to connect to an oracle DB and extract 3 columns from, I need to extract only 1st 3 characters in each column. I used unpack. But, its not working.. Can someone help.. My code is as below..
#!/usr/bin/perl #use strict; use DBI; my $user = "qwer"; my $passwd = "qwer"; my $server = "asdf"; my $database='rd_db'; my $dbd='Sybase'; my $an_dt_file = "an_dt_file"; # Connect to the database my $dbh = DBI->connect($server,$user,$passwd,$dbd, {RaiseError => 1,Au +toCommit => 1 }); # Prepare the SQL query for execution my $sql = "SELECT $ans_rid, $ans_qcn, $ans_loc FROM ft_int_tbl WHERE $ +ans_rid is not null"; my $sth = $dbh->prepare($sql) or die "Couldn't prepare statement:$DBI: +:errstr; stopped"; # Execute the query $sth->execute() or die "Couldn't execute statement: $DBI::errstr; stop +ped"; #open JKLL, ">$an_dt_file" or die "can't open file $ansb_detail_file f +or write,\n"; # Fetch each row and print it while ( my ($ans_rid, $ans_qcn, $ans_loc) = $sth->fetchrow_array() ) { my ($ansb_cktid, $ansb_mcn, $ansb_soc) = unpack("A3 A3 A3", $_); #print JKLL"Field 1: $ansb_cktid Field 2:$ansb_mcn Field 3: $ansb_soc +\n"; print "Field 1: $ansb_cktid Field 2:$ansb_mcn Field 3: $ansb_soc \n"; } # Disconnect from the database $dbh->disconnect();

    [marto]: I'm sure this comes as a surprise to no one
    [LanX]: ?
    [marto]: poorly thought out non products, sold to parents as "fun" things for kids to have, while providing "security" features (track your kid over the interwebs)
    [LanX]: oh didn't see the link, poor contrast
    [marto]: "Through a few simple steps, a stranger can take control of the watch and track, eavesdrop on and communicate with the child. They will be able to track the child as it moves or make it look like the child is somewhere it is not..." and so on
    [LanX]: so Strangers can easily seize control of the children
