You only have to know the total number of record ,which I think you can easily get SELECT id,lot_id,lot_type FROM scrap_table ORDER BY id DESC limit TOT - 1932,10 at the present time I don't remember if ther is a way to do it directly from SQL, but I don't think it's such a great effort ^^ > What I was actually hoping for was something I could add to my original > SELECT statement to perform the task if someone entered the ID but would > show all (limit 10) if there was no entry.

Re: Display information
Hello all again. I think I need to be a little more specific in describing my problem. So, let me try again. I have a database of scrap records. There are currently over 2000 records in this database. I have a web page that queries this database and displays the records in reverse order, newest to oldest. I use this query to do that... SELECT id,lot_id,lot_type FROM scrap_table ORDER BY id DESC LIMIT 0,10 which displays the last 10 records. If I want the next 10 records, I change the limit statement to look like this... LIMIT 10,10 which starts at the 10th record recovered and displays another 10, again from newest to oldest. I have a button on my web page that increments the number of records (LIMIT <##>,10) with each click on the "Pg Up" or "Pg Dn" button. Now, I don't want to page through eight or nine pages to get down to the record I'm looking for. I want to generate a query to display a range of 10 records starting with my entry. Now, the following query will work... SELECT id,lot FROM scrap_table WHERE id >=1880 and id <= 1890 ORDER BY id desc; but I don't always have the starting record number to work with. Now, the following suggestion seemed promising... SELECT id,lot_id,lot_type FROM scrap_table ORDER BY id limit 1932,10; seemed promising but it put them in oldest-to-newest order (ascending), not newest-to-oldest order (desc). When the "desc" qualifier was added, I got records 122 thru 113. Again, not exactly what I was looking for. What I was actually hoping for was something I could add to my original SELECT statement to perform the task if someone entered the ID but would show all (limit 10) if there was no entry. And, I wanted to do it without rewriting my code. Unfortunately, it looks like I may have to do a code rewrite for that section, which means documenting, testing, acceptance... Anyway, thanks for all the suggestions Ron suggestions vie email * > select id,lot_id,lot_type from scrap_table where id >= 1932 order by id > limit 10; > select id,lot_id,lot_type from scrap_table order by id limit 1932,10; > > either should work, i think the first would be faster but I'm not positive > how MySQL would handle the second in terms of optimization. > > -jm ** > If you simply needed the exact result here's the query > > SELECT id,lot_id,lot_type FROM scrap_table WHERE > id BETWEEN 1932 AND 1942 > ORDER BY id DESC ** > isn't it as simple as... > > select id,lot_id,lot_type from scrap_table > where id >= 1932 and id <= 1942 > order by id limit 10; > > ? > > cheers, > > P *** > Have a look in the manual, it says LIMIT [offset], rows, so you should say: > > order by id limit 1932, 10; > - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail Trouble unsubscribing?

AW: Display information
Have a look in the manual, it says LIMIT [offset], rows, so you should say:
order by id limit 1932, 10;
SELECT [STRAIGHT_JOIN] [SQL_SMALL_RESULT] [SQL_BIG_RESULT] [HIGH_PRIORITY]
[DISTINCT | DISTINCTROW | ALL]select_expression,...
[INTO OUTFILE 'file_name' export_options][FROM table_references
[WHERE where_definition][GROUP BY col_name,...]
[HAVING where_definition]
[ORDER BY {unsigned_integer | col_name | formula} [ASC | DESC] ,...]
[LIMIT [offset,] rows]
Tobias.

Hello all,
I have a database with a little over 2000 records. I want to be able to
construct a query that says something like this...
select id,lot_id,lot_type from scrap_table
(part I need help with)
order by id limit 10;
which should give me records 1932 - 1942 like this...
+--+--+--+
| id | lot_id | lot_type |
+--+--+--+
| 1942 | 0034906 | F|
| 1941 | 0100308 | F|
| 1940 | 0036309 | S|
| 1939 | 0033503 | F|
| 1938 | 0034108E | D|
| 1937 | 0034712 | F|

Re: Display information
isn't it as simple as... select id,lot_id,lot_type from scrap_table where id >= 1932 and id <= 1942 order by id limit 10; ? cheers, P > > which should give me records 1932 - 1942 like this... > > +--+--+--+ > | id | lot_id | lot_type | > +--+--+--+ > | 1942 | 0034906 | F| > | 1941 | 0100308 | F| > | 1940 | 0036309 | S| > | 1939 | 0033503 | F| > | 1938 | 0034108E | D| > | 1937 | 0034712 | F| > | 1936 | 0029404 | F| > | 1935 | 0032706 | F| > | 1934 | 0029404 | F| > | 1933 | 0100307 | F| > | 1932 | 0100404 | F| > +--+--+--+ > > > any suggestions? > > Ron > > - > Before posting, please check: >http://www.mysql.com/manual.php (the manual) >http://lists.mysql.com/ (the list archive) > > To request this thread, e-mail <[EMAIL PROTECTED]> > To unsubscribe, e-mail <[EMAIL PROTECTED]> > Trouble unsubscribing?
