Executing Sql query in a Perl script

Friday, December 28, 2012 , , , 0 Comments

Below is the example. Here we can execute a sql query or a sybase query in a perl script. Please also note that I am not utilizing the DBI module provided by perl.
#!/usr/bin/perl
use strict;
use warnings;

my $result = qx { isql -Uxx -Pxxxxxxx -Dxxxx <<EOF
set nocount on
select count(*) from XXX
go
exit
EOF
};
print $result;
Above example show connecting to the sybase database. If you are using Oracle DB, then you can change the connection string:
isql -Uxx -Pxxxxxxx -Dxxxx

to
sqlplus....
Note:
One strange thing over here never add spaces at the begining of the line after the statement isql.....<<EOF
the query will not be executed in such case you will go nuts trying to figure out why!
