Hi Everyone, I wrote a for loop to build several select
statements that are combined with a UNION. When I execute
one of the queries separately, it works, but when I execute
the query with a UNION it returns:
ERROR 2013 (HY000): Lost connection to MySQL server during query
I am able to run additional queries after I get the error, so
the connection is not lost. I have tried running the query
with the union on MySQL Query Browser and also on the
command prompt and I get the same results.
Here is my query:
SELECT DATE_ADD(units_next_bill, INTERVAL 0 MONTH), fees_name AS
Name, IF(fees_percent = 'T', IF(fees_round = 'T', ROUND(fees_amount *
units_pay_amount), ROUND(fees_amount * units_pay_amount, 2)),
fees_amount) AS Amount
FROM unit_dtl
INNER JOIN fees ON unit_dtl_name = fees_name AND unit_dtl.facilityID
= fees.facilityID AND fees_discount = 'T'
INNER JOIN units ON units.facilityID = unit_dtl.facilityID AND
units_unit_id = unit_dtl_unit_id
WHERE (unit_dtl.facilityID = 'matt1' AND unit_dtl_unit_id = 'A3' AND
unit_dtl_active = 'T') AND ((unit_dtl_expires = 'T' AND NOW() <
unit_dtl_exp_date) XOR (unit_dtl_expires = 'F'))
UNION
SELECT DATE_ADD(units_next_bill, INTERVAL 1 MONTH), fees_name AS

units_pay_amount), ROUND(fees_amount * units_pay_amount, 2)),
fees_amount) AS Amount

I am using the MySQL (rpm version) 4.1.10a on a linux system
Linux nighthawk 2.4.21-27.0.2.ELsmp #1 SMP Wed Jan 12 23:35:44 EST 2005
i686 i686 i386 GNU/Linux
Any help would be appreciated.
Thanks,

Here' is the error log. There are some suggestions written
in the log on how to investigate this more in detail. I think
I will start by increasing the key_buffer_size.
mysqld got signal 11;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help diagnose
the problem, but since we have already crashed, something is definitely wrong
and this may fail.
key_buffer_size=268435456
read_buffer_size=1044480
max_used_connections=4
max_connections=100
threads_connected=3
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 466543 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
