NAME

DBIx::SQLEngine::Driver::SQLite - Support DBD::SQLite driver

SYNOPSIS

DBI Wrapper: Adds methods to a DBI database handle.

  my $sqldb = DBIx::SQLEngine->new( 'dbi:SQLite:dbname=mydatafile.sqlite' );

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 SQLite'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

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_postfetch and seq_fetch_current.

seq_fetch_current

  $sqldb->seq_fetch_current( ) : $current_value

Implemented using SQLite's dbh_func() "last_insert_rowid". Note that this doesn't fetch the current sequence value for a given table, since it doesn't respect the table and field arguments, but merely returns the last sequencial value created during this session.

detect_any

  $sqldb->detect_any ( )  : $boolean

Returns 1, as we presume that the requisite driver modules are available or we wouldn't have reached this point.

sql_detect_table

  $sqldb->sql_detect_table ( $tablename )  : %sql_select_clauses

Implemented using SQLite's "select * from $tablename limit 1".

dbms_create_column_types

  $sqldb->dbms_create_column_types () : %column_type_codes

Implemented using SQLite's blob and int auto_increment types.

dbms_create_column_text_long_type

  $sqldb->dbms_create_column_text_long_type () : $col_type_str

Implemented using SQLite's blob type.

dbms_column_types_unsupported

  $sqldb->dbms_column_types_unsupported () : 1

Capability Limitation: This driver does not store column type information.

dbms_indexes_unsupported

  $sqldb->dbms_indexes_unsupported () : 1

Capability Limitation: This driver does not support indexes.

dbms_storedprocs_unsupported

  $sqldb->dbms_storedprocs_unsupported () : 1

Capability Limitation: This driver does not support stored procedures.

dbms_detect_tables_unsupported

  $sqldb->dbms_detect_tables_unsupported () : 1

Capability Limitation: This driver does not return a list of available tables.
