Hello, Is there any way to connect mysql or any other database directly with a solidity smartcontract?

i think via oracle api

great, thanks bro

but only if you have a database which you don't want to lose your data? because blockchain itself is a verifiable and decentralized database already

Can a contract handle and store a huge quantity of data?

Yea thats my concerns also

why not use store the hash of the data by using IPFS

i think pancakeswap is a good example that yea, it can

very interesting

in theory you can store 2^261 bytes but in practice you can never get anywhere near that limit. As Vitalik points on in his post in that link the blockchain will cease to function before you reach that hard limit ;)

I must study a lot now, I have so many new things to do with blockchain. IPFS is new for me

its very powerful what blockchain can do, and yet on a simple way

yea that is interesting approach

you can't pass gas limit though , adding data is limited per transaction/interaction

The gas fees to store all the information would be very expensive

exactly

so normally applications which each user adds and handle its data is the best to work with.

In my case it's better to try IPFS

No u cant connect my sql directly with solidity u can use react js for connect database and using abi u can get all method which u mentioned in solidity contract
