MySQL should be suitable for most modern Linux distributions (I'm not

Mysqldump has where condition, you may have to segment your data and dump
it in diferents files
Mysqldump --where='date between \'dateStart\' and \'dateFinish\' ' (for
example)

The output of mysqldump is standard output, not a file. You can pipe
it into another program, or redirect the output to a file, but
mysqldump does not make a file. Therefore, there is no option in

Do I need to learn C/C++ to have a UDF?
