How to convert Numbers to Words in Pentaho

Que - What I understand is that you want to fetch the Numbers and convert it into Words automatically using Pentaho, right?

Ans - Not sure if Penatho can convert numbers into words.But you could convert it through mysql stored routines/functions and fetch result into pentaho. To do that, Please follow steps as mentioned below:- Step 1 - Go to Heidisql tool, Select database then right click on that and click on Create new - Stored routine. Then update the values as mentioned below:

a) Under Options:-

Name - number_to_word

Definer - root@localhost

Type - Function (returns as result)

Data access - Contains SQL

Returns - text SQL security - Definer

b) Under Routine body:- Copy and replace below content

BEGIN
-- This function returns the string representation of a number.
-- It's just an example... I'll restrict it to hundreds, but
-- it can be extended easily.
-- The idea is:
-- For each digit you need a position,
-- For each position, you assign a string

c)Under Parameter:- Click on Add button and type n

d) Click on Save button.

Step 2 - Test if the value in number converts into word by using select query:-

select number_to_word(round(x.principal_amount)) from m_loan x where x.id=5

Output will show in words for example- fifty thousand.

Step 3- Now you could write your sql query and use that in pentaho designer and generate pentaho report.
