This is likely to be a personal preference thing. As Corion says, some people like to write the SQL directly; others prefer a tool. Personally I use SQL::Abstract::More most of the time. I like it more than SQL::Abstract, upon which it is based, because it allows use of named parameters (I hate positional parameters), and also supports more complex clauses such as joins, etc.

Yes, in a way you will be learning one syntax instead of another. But after becoming familiar with it I think you'll find it intuitive and effective. One thing I really like is not having to think at all about quoting values, or even about placeholders. You write your values right into the call to SQL::Abstract::More, and get back the SQL and a list of bind values that will be plugged into the placeholders by the DBI. Here's an example that's based on a recent script I was working on: 

use SQL::Abstract::More;
my $sql_builder = SQL::Abstract::More->new;

my ( $sql, @bind ) = $sql_builder->select(
    -columns => "id, site_id",
    -from    => "jobs",
    -where   => {
        id => [ 10 .. 20 ],
        first_seen_time => [
            "null",
            { "<" => time - 86400, ">" => time - 86400 * 8 }, 
        ],
    },
);

print " SQL: $sql\n\n";
print "BIND: @bind\n";'

...

Output: 
SQL: SELECT id, site_id FROM jobs WHERE ( ( ( first_seen_time = ? OR (
+ first_seen_time < ? AND first_seen_time > ? ) ) AND ( id = ? OR id =
+ ? OR id = ? OR id = ? OR id = ? OR id = ? OR id = ? OR id = ? OR id 
+= ? OR id = ? OR id = ? ) ) )

BIND: null 1486484465 1485879665 10 11 12 13 14 15 16 17 18 19 20

As you can see the builder adds lots of parentheses, some probably not necessary, but your RDBMS will optimize the query in any case.

Hope this helps!


The way forward always starts with a minimal test.
