Hi,
I am trying to load data into my table from a very large file but after some
time I get this error:
ERROR 2013 (HY000): Lost connection to MySQL server during query
My file size is around 4G and I have 220M lines in my file which have to be
loaded in to my table.
I have 10 of these

The select concat() works from the command line
I can manually add the file name but would like to automate the process
Lastly, if it makes a difference, I don't use any graphical tools for DB stuff.
Look up the command!
By using your shell's variable substitution, I'm afraid.
export outfile='/path/to/file'
mysql -e select blah into outfile '$outfile'
You'll have to build a shell script or something that generates your filename,
and then do an interactive call.
Maybe you could write a stored procedure that

I would like to eventually move this to a stored procedure but for now I am
using the \. to fire it off.
Here is what I have so far (generating a list of machines missing software)
JW,
Youre correct .. that is what I was getting with the LEFT JOIN and
therefore it wasnt the correct answer.
I was able to get the correct answer using UNION ALL, however, like you
said, I needed 2 queries in that case. One to get the PHONE numbers from
both tables
and a 2nd query to get
SELECT *
FROM CUSTOMERS LEFT JOIN CALLS USING(PHONE) WHERE CUSTOMERS.DATE =
02/28/12 OR CALLS.DATE = 02/28/12
^^^ This is going into an endless loop; I'm not getting any result at all.
I'm not sure why. I haven't used USING before so I need to read up a bit on
that to understand what you're doing

I'm sure it'll allow you to download the 64-bit version of the server
