It seems that there is no direct support to limit 'select' to only the
first N rows in a table. Could you let me know what the best way
select rows from the first N rows in a table is?

LIMIT usually works fine ;-)

As Tom Worster said, print($query); would show you what the query was trying
to run.
Without testing it, you also have some other whitespace issues between the
hw.wildlife and FROM, and also, i m unsure of the asterix infront of the
*images.
On another note, when I do my JOINs, I tend to write
Hi All,
I have a query I need to run but can't think how to get this working so I am
hoping someone can advise.
I have a table which logs start and end times of Scheduled jobs. It includes
for simplicity a `DayID`, `StartDateTime` and `EndDateTime` column. Both
`StartDateTime` and `EndDateTime`
Hmm. You seem to have overlap, too. I suspect this would be easiest to do in
code - the data you're looking for doesn't exist in the data you have, only
the opposite of that data does.
You could try populating a table with a full day, using the resolution you
need (1 minute resolution means 1440
Not tested, but I think it can help you or at least give you an ideia on how
to do it.
select
EndDateTime + INTERVAL 1 SECOND as startLazy,
(select StartDateTime - INTERVAL 1 SECOND from table t2 where
t2.StartDateTime t1.EndDateTime limit 1) as endLazy
from
table t1

I have the following statement:
select chart_of_accounts.accountname as Account,
concat('$',format(coalesce(sum(sales_journal_entries.debit),0),2)) as
Debit,
concat('$',format(coalesce(sum(sales_journal_entries.credit),0),2)) as

Hi,
Is it true that the performance of running a query on a live replication
master and slave has to be much slower than running a query on a static
server?
I've tried to run the following query on a replication master and it
takes 1 min 13.76 sec to finish.
SELECT *, ABS(timeA-1266143632)

Try
order by CAST(Balance as decimal(8,2)) asc;
Cast will work in the order by.

Subject: order by numeric value
I have the following
That won't work on a value like $1.00
select CAST('$1.00' as decimal(8,2));
+---+
| CAST('$1.00' as decimal(8,2)) |
+---+
| 0.00 |
+---+
1 row in set, 1 warning (0.00 sec)
But I'd prefer not to see the extra sorting field.

You don't need to select a field in order to be able to order by it.
So
select chart_of_accounts.accountname as Account,
concat('$',format(coalesce(sum(sales_journal_entries.debit),0),2)) as
