NAME

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

CONTENTS

SYNOPSIS

<B>DBI WrapperB>: Adds methods to a DBI database handle.



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



<B>Portability Subclasses:B> 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.
