Introduction

Ethereum JDBC driver implements a pure java, type 4 JDBC driver that can execute SQL queries directly on Ethereum. It uses antlr4.j grammar file to parse the query and create corresponding logical plan. This logical plan is then converted in to an optimized physical plan. The physical plan uses corresponding web3j calls to connect to Ethereum. The driver then converts the returned objects to a JDBC compliant result set and return it to the user. It supports Querying over blocks and transactions associated to each block.
