Execute PgSQL with perl-DBI?

Question

I need to execute complex SQLs at PostgreSQL server .

Something like this:

$sql=<<EOF;
BEGIN;
DO SOME SQL HERE
END;
EOF

$dbh->do($sql) ;

If this is not possible, how can I create and execute stored procedure in DBD::Pg? I have no access to additional software or libraries but perl + DBI

Where is the manuals about how to work with PGSQL by perl-DBI ?

Answer 1

Yes, it is a very possible to execute a complex SQL and stored procedures from a Perl program. See eg

• DBI site
• DBI module documentation
• DBI::do
• How can I invoke stored procedures with DBI?

With PostgreSQL the stored procedure execution example from DBI FAQ is:

$dbh->do( "SELECT someProcedure;" );

Answer 2

Use the DBD::Pg driver; You can find it at cpan: https://metacpan.org/pod/DBD::Pg
