How to create a table report with alphabetic link at the top

Question

Hello,
I have a db table of users, and have created a report based on this table, however I want to have each aphabet letter at the top of the report so that users can click on the letter and see all records where the username field starts with that letter.
How can I achieve this?
Thanks,

Hello user11243298 (please tell us your name),
Your report query would look something like this (assuming page number is 1):
select some_column1, some_column2
from your_user_table
where username like :P1_INITIAL || '%'
For the letters at the top of the report, here's a couple options:
- If you want all letters to appear whether or not there are any rows, you can create a series of buttons or links, one for each letter, and specify the target URL to submit back to the report page, setting the item P1_INITIAL to each letter.
- If you want only letters that have rows, one way is to create a dynamic LOV based on a query like this:
select distinct upper(substr(username, 1, 1)) d, distinct upper(substr(username, 1, 1)) v
from your_user_table
order by upper(substr(username, 1, 1))
Then use that for a select list with submit, again targeting the report page and setting P1_INITIAL to the selected value.
Hope this helps (if it does, please reward it),
