NAME ^

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

SYNOPSIS ^

DBI Wrapper: Adds methods to a DBI database handle.

  my $sqldb = DBIx::SQLEngine->new( 'dbi:CSV:f_dir=my_data_path' );

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 some of DBD::CSV's idiosyncrasies.

Note that DBD::CSV does not support the normal full range of SQL DBMS functionality. Upgrade to the latest versions of DBI and SQL::Statement and consult their documentation to understand their current limits.

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_seq_increment

Overrides behavior of DBIx::SQLEngine::Driver::Trait::NoSequences.

sql_detect_table

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

Implemented using DBD::CSV's "select * from $tablename where 1 = 0".

dbms_null_becomes_emptystring

  $sqldb->dbms_null_becomes_emptystring () : 1

Capability Limitation: This driver does not store real null or undefined values, converting them instead to empty strings.
