I wanted to do a similar thing to put all the transactions in the database (it was PostgreSQL for me, but you can use anything). After some research ended up using [bitcoin abe](https://github.com/jtobey/bitcoin-abe) and it worked great for me. Be patient though, it does take a long time - was several days in my case.
