AnyData::Format::CSV(3pm)				User Contributed Perl Documentation				 AnyData::Format::CSV(3pm)

NAME
AnyData::Format::CSV - tiedhash & DBI/SQL access to CSV data SYNOPSIS
use AnyData; my $table = adTable( 'CSV', $filename,'r',$flags ); while (my $row = each %$table) { print $row->{name}," " if $row->{country} =~ /us|mx|ca/; } # ... other tied hash operations OR use DBI my $dbh = DBI->connect('dbi:AnyData:'); $dbh->func('table1','CSV', $filename,$flags,'ad_catalog'); my $hits = $dbh->selectall_arrayref( qq{ SELECT name FROM table1 WHERE country = 'us' }); # ... other DBI/SQL operations DESCRIPTION
This is a plug-in format parser for the AnyData and DBD::AnyData modules. It will read column names from the first row of the file, or accept names passed by the user. In addition to column names, the user may set other options as follows: col_names : a comma separated list of column names eol : the end of record mark, by default quote_char : the character used to quote fields " by default escape_char : the character used to escape the quote char, " by default If you are using this with DBD::AnyData, put ad_ in front of the flags, e.g. ad_eol. Please refer to the documentation for AnyData.pm and DBD::AnyData.pm for further details.
