Re: Re: GROUPING and ORDERING and CONFUSION

Hmm, souynds like you want all the ruples returned, right? Then it's not
really a GROUP problem, just an ORDER BY one. If all your data follows
the example you gave, this should work:


reedstrm=# select * from fred order by text(num); num   |                  name                  
--------+----------------------------------------    15 |  First Category Heading  1510 |  first category subheading
1511|  second category subheading  1560 |  spurious category subheading156010 |  first spurious category
subheading156011|  second spurious category subheading    16 |  Second Category Heading  1610 |  Second category
subheading161010|  Second category subheading subheading
 
(9 rows)

However, I _think_ your deeper question has to do with the indentation
part, right? Are you trying to indent based on category level? If you've got
some sort of programming language between your output and the SQL, then
something like:

reedstrm=# select text(num) as num ,length( text(num))/2 as level, name from fred order by text(num); num   | level |
              name                  
 
--------+-------+----------------------------------------15     |     1 |  First Category Heading1510   |     2 |
firstcategory subheading1511   |     2 |  second category subheading1560   |     2 |  spurious category
subheading156010|     3 |  first spurious category subheading156011 |     3 |  second spurious category subheading16
|     1 |  Second Category Heading1610   |     2 |  Second category subheading161010 |     3 |  Second category
subheadingsubheading
 
(9 rows)

Then use the 'depth' to output the proper indentation level.
