::MySQL/TableInfo version 1.01::..
============================
:DESCRIPTION:.
MySQL::TableInfo is a handy class for getting easy access to MySQL tables' descriptions
which is available via
DESCRIBE table_name, SHOW COLUMNS FROM table_name
queries. It's also handy for constructing form based CGI applications to control HTML forms'
attributes such as C<VALUE>, C<SIZE>, C<MAXLENGTH>, C<TYPE> and so forth.
For example, if you have a ENUM('Yes', 'No') column in your mysql table, then you normally
would present it either as a group of radio buttons, or as a <SELECT> menu. If you modify
the column, and add one more option, ENUM('Yes', 'No', 'N/A'), then you will have to
re-write your html code accordingly. By using MySQL::TableInfo, you can avoide this double
troubles. Consider the following code:
use CGI;
use DBI;
my MySQL::TableInfo;
my $CGI = new CGI:
my $dbh = DBI->connect(....);
my $table = new MySQL::TableInfo($dbh, "bio");
print $CGI->header, $CGI->start_html("MySQL::TableInfo");
print $CGI->start_form,
$CGI->div("Do you wear beard?"),
$CGI->popup_menu(-name=>'has_beard',
-values=>[$table->set('beard')],
-default=>$table->default('beard')),
$CGI->end_form;
print $CGI->end_html;
As you see, modifying 'beard' column, which is an enumeration column, whould
reflect in your CGI too.
