Tip : Usage of COLUMN_NUMBER variable in Jaspersoft Studio reports

Hi folks,

Recently, I wrote about the usage of horizontal display (looks like vertical display) of sql output in jaspersoft studio at read it here.

At report level to display the row number with detail band we use "REPORT_COUNT" variable, what if you want to display the column numbers when displaying the records in horizontal view(looks like vertical) ?

Use "COLUMN_NUMBER" variable in a text expression. i.e., ${COLUMN_NUMBER}.


Watch video tutorial for the same example below(with voice)


Sample screenshot is shown in below: (An example of fixed number of customers to display)

JRXML: ( Supports in 6.4.2 Pro or later) - The example uses "foodmart" db of postgresql.
