Can you show an example with code building the query string for the arrays? | [reply] |
use strict;
use List::MoreUtils qw/zip/;
use DBI;
my @reg_num = qw/12345 98564 33234 112345 87564 2345678 938566 1234486
+ 223456 123488/;
my @month = qw/03 01 01 10 05 11 03 05 02 09/;
my $sql_part = join ' or ', map {'(reg_num = ? AND month = ?)'} 1 .. @
+reg_num;
my $dbh = DBI->connect("DBI:ODBC:$myserver",$u, $p,);
my $sth = $dbh->prepare(
"SELECT name, last_name, reg_num, month, year
FROM members
WHERE $sql_part AND year='2009");
$sth->execute(zip @reg_num, @month);

There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James

What about something like this:
use strict;
use DBI;
my @reg_num = qw/12345 98564 33234 112345 87564 2345678 938566 1234486
+ 223456 123488/;
my @month = qw/03 01 01 10 05 11 03 05 02 09/;
my $dbh = DBI->connect("DBI:ODBC:$myserver",$u, $p,);
my $sql = "select name, last_name, reg_num, month, year
+ from members
where year='2009' AND (";
for my $i (0 .. $#reg_num)
{
$sql .= "reg_num = '$reg_num[$i]' AND month = '$month[$i]' ";
$sql .= 'OR ' unless $i == $#reg_num;
}
$sql .= ')'; # don't forget the ) on the end of the SQL
my $sth = $dbh->prepare($sql, { RaiseError => 1 });
$sth->execute();
Let me know what you think?! | [reply]
