Hi, Sorry to disturb but Mysql 4.1.4 gamma goes down when executing this
query.
I've tryed the same query without the coalesce function and the problem
persists.
select
coalesce(viehc,0),
coalesce(vieapellido,0),
coalesce(vienombres,0),
coalesce(viedoc,0),
coalesce(numero,0),
coalesce(apellido,0),
coalesce(nombres,0),
coalesce(f_nacimiento,0),
coalesce(sexo,0),
coalesce(doc_numero,0)
from zzg_int.compara
into outfile "/tmp/compa.txt"
fields terminated by ','
lines terminated by '\r\n';
This is what the error log shows.
Version: '4.1.4-gamma-standard-log' socket: '/tmp/mysql.sock' port:
3306 Official MySQL-standard binary
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=16777216
read_buffer_size=258048
max_used_connections=13
max_connections=100
threads_connected=10
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections
= 92783 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...
Cannot determine thread, fp=0xbfddeb68, backtrace may not be correct.
Stack range sanity check OK, backtrace follows:
0x808a183
0x82d3cb8
0x80ae46f
0x809d894
0x8097e4f
0x80977d8
0x8096f17
0x82d146c
0x82fa9fa
New value of fp=(nil) failed sanity check, terminating stack trace!
Please read http://www.mysql.com/doc/en/Using_stack_trace.html and
follow instructions on how to resolve the stack trace. Resolved
stack trace is much more helpful in diagnosing the problem, so please do
resolve it
