Hi,
Where should I increase max_allowed packet??
I get a error from Windows (yes, I know... it's running on a M$-os, not
my bad - not my desicion).
The results is about 2 - 10 Gb of data.
Regards,

Increase max_allowed packet to 1.5 gb and then try to import your data .
eg ;
In mysql prompt run the file as
*use database \. /tmp/filename.txt

Hi,
I need to extract some data to a textfile from a big database.
If I try to do like this:
mysql < queryfile.sql > outfile.txt
"outfile.txt" it looks something like:
"OrderID", "Quant", "OrdrDate", "code1", "code2"...
10021, 12, 20060412, 23, 95...
10022, 5, 20060412, , 75...
But, I never get a complete file. I get a out of memory error after a
hour or 2!!
If I instead insert the following code in queryfile.sql:
"INTO OUTFILE 'outfile.txt'"
Now my outfile.txt don't get the first row with the column names, and
any NULL values are exported as "\N".
This is a big problem, cause the import function that exist where I
send the data only accept the format I get using "mysql <
queryfile.sql > outfile.txt".
Any help??! Ideas??
Can I in any way format my output to print the column names and print
NULL values as 'nothing'??
