NAME
       DBD::Excel -  A class for DBI drivers that act on Excel File.

       This is still alpha version.

SYNOPSIS
           use DBI;
           $hDb = DBI->connect("DBI:Excel:file=test.xls")
               or die "Cannot connect: " . $DBI::errstr;
           $hSt = $hDb->prepare("CREATE TABLE a (id INTEGER, name CHAR(10))")
               or die "Cannot prepare: " . $hDb->errstr();
           $hSt->execute() or die "Cannot execute: " . $hSt->errstr();
           $hSt->finish();
           $hDb->disconnect();

DESCRIPTION
       This is still alpha version.

       The DBD::Excel module is a DBI driver.  The module is based on these modules:

       o   Spreadsheet::ParseExcel

           reads Excel files.

       o   Spreadsheet::WriteExcel

           writes Excel files.

       o   SQL::Statement

           a simple SQL engine.

       o   DBI

           Of course. :-)

       This module assumes TABLE = Worksheet.  The contents of first row of each worksheet as
       column name.

       Adding that, this module accept temporary table definition at "connect" method with
       "xl_vtbl".

       ex.
           my $hDb = DBI->connect(
                   "DBI:Excel:file=dbdtest.xls", undef, undef,
                               {xl_vtbl =>
                                   {TESTV =>
                                       {
                                           sheetName => 'TEST_V',
                                           ttlRow    => 5,
                                           startCol  => 1,
                                           colCnt    => 4,
                                           datRow    => 6,
                                           datLmt    => 4,
                                       }
                                   }
                               });

       For more information please refer sample/tex.pl included in this distribution.

   Metadata
       The following attributes are handled by DBI itself and not by DBD::Excel, thus they all
       work like expected:

           Active
           ActiveKids
           CachedKids
           CompatMode             (Not used)
           InactiveDestroy
           Kids
           PrintError
           RaiseError
           Warn                   (Not used)

       The following DBI attributes are handled by DBD::Excel:

       AutoCommit
           Always on

       ChopBlanks
           Works

       NUM_OF_FIELDS
           Valid after "$hSt->execute"

       NUM_OF_PARAMS
           Valid after "$hSt->prepare"

       NAME
           Valid after "$hSt->execute"; undef for Non-Select statements.

       NULLABLE
           Not really working, always returns an array ref of one's.  Valid after
           "$hSt->execute"; undef for Non-Select statements.

       These attributes and methods are not supported:

           bind_param_inout
           CursorName
           LongReadLen
           LongTruncOk

       Additional to the DBI attributes, you can use the following dbh attribute:

       xl_fmt
           This attribute is used for setting the formatter class for parsing.

       xl_dir
           This attribute is used only with "data_sources" on setting the directory where Excel
           files ('*.xls') are searched. It defaults to the current directory (".").

       xl_vtbl
           assumes specified area as a table.  See sample/tex.pl.

       xl_skiphidden
           skip hidden rows(=row height is 0) and hidden columns(=column width is 0).  See
           sample/thidden.pl.

       xl_ignorecase
           set casesensitive or not about table name and columns.  Default is sensitive (maybe as
           SQL::Statement).  See sample/thidden.pl.

   Driver private methods
       data_sources
           The "data_sources" method returns a list of '*.xls' files of the current directory in
           the form "DBI:Excel:xl_dir=$dirname".

           If you want to read the subdirectories of another directory, use

               my($hDr) = DBI->install_driver("Excel");
               my(@list) = $hDr->data_sources(
                               { xl_dir => '/usr/local/xl_data' } );

       list_tables
           This method returns a list of sheet names contained in the $hDb->{file}.  Example:

               my $hDb = DBI->connect("DBI:Excel:file=test.xls");
               my @list = $hDb->func('list_tables');

TODO
       More tests
           First of all...

       Type and Format
           The current version not support date/time and text formatting.

       Joins
           The current version of the module works with single table SELECT's only, although the
           basic design of the SQL::Statement module allows joins and the likes.

KNOWN BUGS
       o       There are too many TODO things. So I can't determind what is BUG. :-)
