       This is still alphaversion.

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

       •   Spreadsheet::ParseExcel

           reads Excel files.

       •   Spreadsheet::WriteExcel

           writes Excel files.

       •   SQL::Statement

           a simple SQL engine.

       •   DBI

           Of course. :-)

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

       Adding that, this module accepts a temporary table definition in the "connect" method with the  "xl_vtbl"
       option.

       Example:

           my %options = (
               xl_vtbl => { # define temporary tables here
                   TESTV => { # temporary table name => options
                       sheetName => 'TEST_V', # actual Excel sheet name
                       ttlRow    => 5,
                       startCol  => 1,
                       colCnt    => 4,
                       datRow    => 6,
                       datLmt    => 4,
                   }
               }
           );
           my $dbh = DBI->connect("DBI:Excel:file=dbdtest.xls", undef, undef, \%options);

       For more information please refer to the file sample/tex.pl which is 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 "$sth->execute"

       NUM_OF_PARAMS
           Valid after "$sth->prepare"

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

       NULLABLE
           Not really working, always returns an array ref of one's.  Valid after "$sth->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 attributes:

       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.  Seesample/tex.pl.

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

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

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

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

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

       •       There are too many TODO things. So I can't determine what is BUG. :-)

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

       This is still alpha version.

       DBI, Spreadsheet::WriteExcel, Spreadsheet::ParseExcel, SQL::Statement

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

       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.
