Re: Looks are important

MessageHi Louise, Josh,

Thanks for the suggestions.

What I'm trying to accomplish is to have a space between no and kind. Length(no) can vary. I would like all the kinds to line up evenly when displayed, with a space between no and kind. But when I RPAD no (to try and get an even starting point for kind), the ' 's are not quite the same width as an ordinary number or letter. Thus the physical display length of "30 characters" (padded) can vary from row to row. The result is that the kinds don't necessary line up neatly. I need to concatenate the two as they are being displayed as one column in a drop down combobox.

Is what I'm trying to do possible???

George

Try the TRIM function or the LTRIM function:

SELECT RPAD(no,30,' ') || TRIM(tableb.kind) FROM tablea
WHERE tablea.kind = tableb.kind

Hi Everyone,

I am trying to concatenate two fields through a query:

SELECT RPAD(no,30,' ') || tableb.kind FROM tablea
WHERE tablea.kind = tableb.kind

The result gives (for example):

4595448 Green
5966 Yellow
106-60033 Green
15-94-387 Red
217-991173 Blue

What I would like to have is better alignment:

4595448 Green
5966 Yellow
106-60033 Green
15-94-387 Red
217-991173 Blue

Is there some kind of encoding or other string options that will result in better alignment than what I've tried with Rpad?

Thanks in advance,
George
