smart contract variables

[bsollenb54]

Hi Xiaoyao,

I'm a big fan of this work! I'm curious if the transaction table has columns to support querying stated variables from a .sol when it's stamped onto an executed transaction. Is this all stored in the hexadecimal-stored input_value column only and indecipherable? Or is it possible to parse the stated variables into unique columns for querying?

Thanks!

Hi, Thanks for the interest :) it's definitely possible, but I believe that would require having an instrumented ethereum client. I heard that's what etherscan did. On the other hand, querying state variables is essentially making eth_call function against a client right? Can you think of a good SQL semantics around this?
