I have table and I want to swap the values from two rows. I have the rows IDs of the two rows.
Is there any query to do that? Here is an example. Before the query I have this:

row1 : 5,6,7
row2 : 1,2,3

Trying to get something similar for Firefox extension using XUL. The most difficult part is the grid with unequal number of rows.
I tried <grid> but it didn't work well. Also don't want to use HTML inside of XUL. Any ideas how to build such table?
I'm struggling getting my head around the Django's ORM. What I want to do is get a list of distinct values within a field on my table .... the equivalent of one of the following:
SELECT DISTINCT myfieldname FROM mytable
(or alternatively)
SELECT myfieldname FROM mytable GROUP BY myfieldname
I'd at least like to do it the Django way before resorting to raw sql.

"1" "I am the Top Father" "1"
"2" "My Father Is 1" "1"
"3" "My Father Is 2" "2"
"4" "My Father Is 2" "2"
How is my bean suppose to look like?

How can I change the Default Size of the filterBy text box in Rich Table? In all the columns, it has a same (fix) size.
I used the property width, but it didn't work.
eg:table
pkey --guid
annualpay
datefrom
dateto--if null means current record
percentannualincrease
percent annual increase will be calculated only if there is a difference in newly inserted and previously existing last differing value.
percentannualincrease =
([newannualpay-just previous pay(if different from current)]/newannualpay)*100
eg
newid(),5000,today,null,0--very first row
newid(),5000,today+1,null(*),0
newid,5500,today+2,null(*),?????????????--> need to be calculated before insert
*--insert will close the previous record by updating dateto=null to todays date
How can I do this stuff in a trigger???

We had a process that crashed while trying to manipulate an expected mysql record set, running the offending query from the mysql cli showed the following.
mysql SELECT ...;
ERROR 1030: Got error 127 from table handler
Is there a way to easily recreate this condition so we can validate our fix ? (production DB was already repaired).

I am getting data from a query and processing it using Javascript in the xaction file.
Now I want to pass the processed data (a 2D array) down to a prpt where it will be used to generate graph and table.
What is the format in which Javascript would generate the data and how is it passed to and received by the prpt file from the xaction.
Thanks...
I was trying to run the following query
UPDATE blog_post SET `thumbnail_present`=0, `thumbnail_size`=0, `thumbnail_data`=''
WHERE `blog_post` NOT IN (
SELECT `blog_post`
FROM blog_post
ORDER BY `blog_post` DESC
LIMIT 10)
But Mysql doesn't allow 'LIMIT' in an 'IN' subquery.
I think I can make a select to count the table rows and then make an ordered update limited by 'COUNT - 10', but I was wondering if there is a better way.
Thanks in advance.
can any one explain hiow this query works..It's for getting the Nth largest elemet from a table.here it's 4 th largest
SELECT a.ID
FROM tblitem a
WHERE (4) = (select count(*)
from tblItem b
where b.id < a.id)
Thanks in advance
i am calling the data from xml in table view. after the the first row of data in tableview, my second row is empty in tableview, and from third row data is available. but my last data for row is missing from tableview, because of the second row.

My table looks like this with duplicates in col1
col1, col2, col3, col4
1, 1, 0, a
1, 2, 1, a
1, 3, 1, a
2, 4, 1, b
3, 5, 0, c
I want to select distinct col1 with max (col3) and min(col2);
so result set will be:
col1, col2, col3, col4
1, 2, 1, a
2, 4, 1, b
3, 5, 0, c
I have a solution but looking for best ideas?
