NAME

DBI::ResultPager - creates an HTML-based pager for DBI result sets.

SYNOPSIS

 # Create a pageable result set
 my $rp = DBI::ResultPager->new;
 $rp->dbh($dbh);
 $rp->query('select books.title, authors.name
             from books
	     inner join (books.author_id = authors.id)');
 $rp->display();

 # The same result set, but sorted with nicer column headings
 my $rp = DBI::ResultPager->new;
 $rp->dbh($dbh);
 $rp->query('select books.title as "Title", 
             authors.name as "Author"
             from books
	     inner join (books.author_id = authors.id)');
 $rp->defaultOrder('Title');
 $rp->display();

 # Adding a custom formatter to build links
 my $rp = DBI::ResultPager->new;
 $rp->dbh($dbh);
 $rp->query('select books.title as "Title", 
             books.isbn as "ISBN",
             authors.name as "Author"
             from books
	     inner join (books.author_id = authors.id)');
 $rp->addColumnFormatter('ISBN', \&linkISBN);
 $rp->display();

 sub linkISBN {
     my($isbn) = shift;
     return '<a href="http://isbndb.com/search-all.html?kw=' .
         $isbn . '">ISBNdb</a>';
 }

 # Adding a custom column and hiding an identity column
 my $rp = DBI::ResultPager->new;
 $rp->dbh($dbh);
 $rp->query('select books.id,
             books.title as "Title", 
             from books');
 $rp->hideColumn('books.id');
 $rp->addCustomColumn('Functions', \&bookFunctions);
 $rp->display();
 
 sub bookFunctions {
   my (@row) = (@_);
   return '<a href="delete.cgi?id=' . $row[0] . '">delete</a>';
 }
 

DESCRIPTION

This class is a quick and easy method of paging result sets returned from the DBI database interface. It takes a standard SQL query along with a database handle and performs the query, inserting the resultant rows into a pageable HTML table. Various options such as sort order can be adjusted, and columns can have formatters attached. Columns can also be hidden, and custom columns can be added to the output.
