NAME

DBIx::SQL::Abstract - Provides a convenient abstraction layer to a database.

SYNOPSIS

  use DBIx::SQL::Abstract;

  my $dbh = DBIx::SQL::Abstract->new( %dbcfg );

  Building SQL Abstractions.

  my($query, @bind) = $dbh->select($table, \@fields, \%where, \@order);
  my($query, @bind) = $dbh->insert($table, \%fieldvals || \@values);
  my($query, @bind) = $dbh->update($table, \%fieldvals, \%where);
  my($query, @bind) = $dbh->delete($table, \%where);

  Using DBI methods

  my $sth = $dbh->prepare($query);
  $sth->execute(@bind_params);
  ...
  my $rc  = $dbh->begin_work;
  my $rc  = $dbh->commit;
  my $rc  = $dbh->rollback;
  my $rc  = $dbh->disconnect;

  Anything else DBI method can be used, by Example:

  my $err = $dbh->err;
  my $err = $dbh->errstr;
  my $rv  = $dbh->state;
  my $rc  = $dbh->DESTROY;

DESCRIPTION

The intention of this module is to join some methods from the DBI and the SQL::Abstract modules, for a convenient and easy use.

To begin, we create an object, but first we must create a hash which contains the database parameters as follows.

    my %dbcfg = { PrintError => 1,
                  RaiseError => 0,
                  AutoCommit => 0,
                  ChopBlanks => 1 
                  driver => 'Pg',
                  dbname => 'db',
                  host => undef,
                  port => undef,
                  user => 'user',
                  passwd => undef
                };

Notice that this parameters are set as default unless you set your required values.

my $dbh = DBIx::SQL::Abstract->new( %dbcfg );

This object automatically creates the connection with the database, and gets the methods listed above.

EXPORT

None by default.
