how to save or retrieve data from mysql when we cannot open it anymore?

I am trying to save or retrieve data from my co-worker开发者_Python百科s computer. Her MySQL instance does not work anymore (cannot figure out the reasons). I would like to know if there is a way to save all the data from the databases present in her computer.

Any suggestions on how to save the data, and maybe re-install MySQL again?

You can copy the tables to another computer with a working MySQL instance, as long as the floating point format is the same on both computers (see this page for reference, covered in the first paragraph).

As long as you copy the .frm, .myd and .myi files somewhere safe, you can also try reinstalling MySQL and see if that works for you.

First of all, errors may be recoverable. If you do not have ability to recover from errors, you can try to make a plain copy of MySQL data. BUT! If tables used InnoDB engine, that will be not so easy and chance of recovery will be not so big.
