   $dbo_data->execute("sp_FinancialResults 'Q3'");

my $report = new SAL::WebDDR;
   $report->{datasource} = $dbo_data;
   $report->{dfm_column} = '0';			# Data Formatting Markup is in column 0

Eponymous Hash

This section describes some useful items in the SAL::WebDDR eponymous hash. Arrow syntax is used here for readability, but is not strictly required.

Note: Replace $SAL::WebDDR with the name of your database object... eg. $report->{datasource} = $dbo_data

Datasource
$SAL::WebDDR->{datasource} is a reference to a SAL::DBI object
Formatting Control
$SAL::WebDDR->{dfm_column} tells SAL::WebDDR where to look for DFM (Data Formatting Markup) tags
$SAL::WebDDR->{skip_fields} specifies columns you want to skip in the reports output.

Constructors

new()

Builds a data-driven reporting object.

Methods

$canvas = build_window($titlebar, $canvas, $statusbar, $width)

Builds a window-like html table using 3 scalars: $titelbar, $canvas, $statusbar. $width is optional.

$canvas = build_scroll_window($titlebar, $canvas, $statusbar, $width)

Same as build_window() but uses an iframe for the main window content ($canvas). JScript is used to copy the contents of $canvas into the iframe.

$canvas = build_iframe_window($titlebar, $url, $statusbar, $width)

Same as build_scroll_window() but the embedded iframe retrieves it's content from $url.

$canvas = build_data_table($datasource, $commify, $highlight_negatives, $width)

Build's a simple spreadsheet-like table using $datasource (a SAL::DBI object).

NOTE: This method does not use it's internal datasource connection. (~fixme)

If you want your numbers with commas, set $commify to a non-zero value.

If you'd like negative numbers highlighted, set $highlight_negatives to a non-zero value.

$width is optional, defaulting to 100%

$canvas = build_report()

Build's a data driven report. Please see the file 'salreport.cgi' in the samples directory.
