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.
