Hi,
could you help me.

I have DB table tab with column (id, number).
The column number means number of star(*), which is display before every row(DB record).
I'd like to display result of DB query(select * from tab) in this way:
(I used JDBC connection.)

1,0
*2,1
***3,3
**4,2
...

Could you help to beginner.
Thanks

See if the function LPAD works for you.

Quoting from a private message from manu chao:
I'd like to java solution, not DB solution.


Here's how you can pad the left side of a String with a given number of asterisks in Java:

1. You can create a StringBuffer object that is initially empty.
2. Calculate the number of astericks to append. number - string.length()
3. Append the asterisks to the StringBuffer object
4. Append the original String object to the StringBuffer object
5. Convert the StringBuffer to a String with: sb.toString()

I'll leave it up to you to convert this to actual Java code.
