NAME

DBX::Simple - Yet another DBI simplification wrapper.

VERSION

Version 0.01

SYNOPSIS

This is my DBI wrapper. There are many like it, but this one is mine.

I have a horrible memory for syntactic detail. This is one reason I've been developing a semantically oriented programming language for the past decade, but in the meantime, when I write Perl to manage my accounting or suck data from the Web, I use SQLite through DBI and I just can't ever remember the syntax. I don't know why. I'm usually fine on SQL syntax, at least for the basic things I do most of the time, but the actual DBI methods escape me again and again.

This module is the syntax in my head, just so I don't have to keep looking everything up every single time. The class subclasses DBI anyway, so anything you would do in DBI, you can do here - but with some simplifying alternative methods as well.

use DBX::Simple;

my $dbh->DBX::Simple->connect(--DBI syntax--);  # Just so I can support everything DBI supports, after looking it up.
my $dbh->DBX::Simple->open('sqlite file');      # 99% of my work. ->mysql and ->postgresql would also be reasonable.

my $value = $dbh->get ('select value from table where id=?', $id);  # Single value retrieval in one whack.
my @rows = $dbh->select ('select * from table'); # Rowset retrieval. Yes, I know about selectrow_array. I just can't remember it.
my $iter = $dbh->iterate ('select * from table'); # Returns an iterator that returns row arrayrefs.
my $sth = $dbh->prepare (--DBI syntax--);

$dbh->do ("insert ...");  # Regular insertion, just like in DBI, except the hashref is skipped because I can never remember it.
my $record = $dbh->insert ("insert ..."); # Calls last_insert_id ('', '', '', ''), which will likely fail except with SQLite.

Simple. Like the name says. And exposes DBI anyway for when simple won't cut it, or when DBI is already simple.

One thing to notice: the class structure differs from DBI. DBX::Simple actually subclasses DBI::db - except for the connect method. So any class-level calls should still be done through DBI, not DBX::Simple. (Easy for me to forget, as I never actually do class-level stuff, except for those very rare times when I do.)

SUBROUTINES/METHODS

open

The open method opens an SQLite database file. Uses 'db.sqlt' if no filename is provided.

get

The get method retrieves a single value. I do this a lot and it's a pain to bind variables for one stinking value.

select

The select method retrieves an array of arrayrefs for the rows returned from the query. In scalar mode, returns the arrayref from fetchall_arrayref.

iterate

This could be done from the Data::Tab end as well, but sometimes I already have a perfectly good dbh and all I want is to iterate rows without the overhead of loading them all at once.

insert

The insert command calls last_insert_id after the insertion. Just a little shorthand.

do

The do command works a little differently; DBI's version wants a hashref of attributes that I never use and regularly screw up.
