NAME

DBIx::SQLEngine::Driver::Pg - Support DBD::Pg

SYNOPSIS

DBI Wrapper: Adds methods to a DBI database handle.

  my $sqldb = DBIx::SQLEngine->new( 'dbi:pg:test' );
    

Portability Subclasses: Uses driver's idioms or emulation.

  $hash_ary = $sqldb->fetch_select( 
    table => 'students' 
    limit => 5, offset => 10
  );

DESCRIPTION

This package provides a subclass of DBIx::SQLEngine which compensates for Postgres's idiosyncrasies.

About Driver Subclasses

You do not need to use this package directly; when you connect to a database, the SQLEngine object is automatically re-blessed in to the appropriate subclass.

sql_limit

  $sqldb->sql_limit( $limit, $offset, $sql, @params ) : $sql, @params

Adds support for SQL select limit clause.

do_insert_with_sequence

  $sqldb->do_insert_with_sequence( $sequence_name, %sql_clauses ) : $row_count

Implemented using _seq_do_insert_preinc and seq_increment.

seq_increment

  $sqldb->seq_increment( $table, $field ) : $new_value

Increments the sequence, and returns the newly allocated value.

dbms_create_column_types

  $sqldb->dbms_create_column_types () : %column_type_codes

Implemented using Pg's bytea and serial types.

dbms_create_column_text_long_type

  $sqldb->dbms_create_column_text_long_type () : $col_type_str

Implemented using Pg's text type.
