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.
