DBD::Excel - A class for DBI drivers that act on Excel File.
This is still alpha version.
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();
This is still alpha version.
The DBD::Excel module is a DBI driver.
The module is based on these modules:
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.
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
$hSt->execute; undef for Non-Select statements.
These attributes and methods are not supported:
bind_param_inout
CursorName
LongReadLen
LongTruncOk
Additional to the DBI attributes, you can use the following dbh
attribute:
- xl_fmt
-
This attribute is used for setting the formatter class for parsing.
- xl_dir
-
This attribute is used only with
data_sources on setting the directory where
Excel files ('*.xls') are searched. It defaults to the current directory (``.'').
- xl_vtbl
-
assumes specified area as a table.
See sample/tex.pl.
- xl_skiphidden
-
skip hidden rows(=row height is 0) and hidden columns(=column width is 0).
See sample/thidden.pl.
- xl_ignorecase
-
set casesensitive or not about table name and columns.
Default is sensitive (maybe as SQL::Statement).
See sample/thidden.pl.
- data_sources
-
The
data_sources method returns a list of '*.xls' files of the current
directory in the form ``DBI:Excel:xl_dir=$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');
- 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.
-
There are too many TODO things. So I can't determind what is BUG. :-)
