There is a HUGE limit on the size of the results of a query but I don't
know exactly what yours will be. I do know it should be more than 2GB so I
don't think your 4500 fields of data (300X15) will meet that limit.
However, there is a practical limit on how many queries can be UNIONed
into one
Works great.
Is the a limit on the size of the query. There are
currently 50 queries (may go upto 300 in future) and
each has 15 cols (250b each query) which makes the
entire query 12kb (250 x 50).
Thanks,
Jay

Right.
(SELECT col1, col2, col3, col4 FROM table1, table2
WHERE table1.col1 = table2.col1 and table1.col2 = 1
ORDER BY col3 DESC LIMIT 5)
UNION
(SELECT col1, col2, col3, col4 FROM table1, table2

I believe you need to combine the results of 3 separate queries (each with
a limit of 5) into a temp table and respond with the contents of the table
you built. If I read this correctly
(http://dev.mysql.com/doc/mysql/en/UNION.html) you could do the same thing
with a UNION query and skip the t
Yes. I want to retrieve 5 of each.
If I put LIMIT 5, the entire query retrieves only 5
for table1.col2 with value of 1 because 1 is the first
in the IN (1,2,3) clause.
If I put LIMIT 15, the query returns 15 rows same as
above instead 5 for each 1, 2, and 3 values. This is
because there are more
Why do you think it doesn't work with LIMIT? Do you want 5 of each?

I have multiple queries like this:

Yes, use LIMIT clause to get only certain number of rows. For example, to retrieve
forst 10 rows use the following statement:
SELECT .. FROM .. ORDER BY .. LIMIT 0,10;
Then to retrieve next 10 rows:
SELECT .. FROM .. ORDER BY .. LIMIT 10,10; retrieve rows 11-20

I am trying to split the results from a select query across several pages.
I have a contacts database and if someone searches for a contact who has a
name like %mith% I want it to return the results with a page across the
bottom, like google.
How do I do this with mySQL and ASP or PHP? I understa
