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: * 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 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 formating. 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. :-) AUTHOR
