NAME ^

Querylet::Output::Excel::OLE - output query results to Excel via OLE

VERSION ^

version 0.143

SYNOPSIS ^

 use Querylet::Output::Excel::OLE;
 use Querylet;

 database: bogosity

 query:
   SELECT detector_id, measurement
   FROM   bogon_detections

 output format: excel

DESCRIPTION ^

Querylet::Output::Excel::OLE provides an output handler for Querylet that will create a new instance of Microsoft Excel using Win32::OLE and populate a worksheet with the query results.

METHODS ^

This module isa Querylet::Output, and implements the interface described by that module.

default_type

The Excel::OLE handler is by default registered for the 'excel' type.

handler

The Querylet::Output::Excel::OLE handler returns a coderef that, when called, will create an Excel.Application object, then create a workbook, and then populate its worksheet with the querylet's results.

If the "excel_workbook" and "excel_worksheet" options are set, it will attempt to open the named workbook file and put its results into the named worksheet, creating it if necessary. If the workbook, but not worksheet, is set, it will create a new worksheet in the named workbook.

If the "excel_postprocessing_callback" option is set, the handler will try to evaluate it into a code reference, the code reference will be called after all other processing is done. It will be passed a hash reference with the following keys:

 query     - the Querylet::Query object being output
 excel     - the Excel.Application object
 workbook  - the Workbook object
 worksheet - the Worksheet object

FUNCTIONS ^

column_name

  column_name($column_number)

This converts a column number to a column name, Excel style. In other words:

    1 -> A
   26 -> Z
   27 -> AA
 2600 -> CUZ
