Ethereum JDBC driver implements a pure java, type 4 JDBC driver that executes SQL queries on Ethereum blockchain. It facilitates getting the data in and out of ethereum in JDBC compliant manner. The Ethereum JDBC driver can be used to  perform ETL, BI reporting and analytics using the familiar SQL language.

It uses [blkchn-sql-driver](https://github.com/Impetus/blkchn-sql-driver) to parse the query and create corresponding logical plan. This logical plan is then converted into an optimized physical plan. The driver extends and implements the physical plan using corresponding [web3j](https://github.com/web3j/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.

Building ethereum-jdbc-connector

==========================

- [Download](https://github.com/Impetus/blkchn-sql-driver/archive/master.zip) or clone blkchn-sql-driver project `git clone https://github.com/Impetus/blkchn-sql-driver.git`

- build blkchn-sql-driver using `mvn clean install -Pgen-sources`

- [Download](https://github.com/Impetus/eth-jdbc-connector/archive/master.zip) sourcecode or use `git clone https://github.com/Impetus/eth-jdbc-connector.git`

- build it using `mvn clean install` 

# Getting Started

- Navigate to [examples](https://github.com/Impetus/eth-jdbc-connector/tree/master/eth-jdbc-examples) folder

- Run [`Query.java`](https://github.com/Impetus/eth-jdbc-connector/blob/master/eth-jdbc-examples/src/main/java/com/impetus/blkchn/eth/Query.java) and [`Insert.java`](https://github.com/Impetus/eth-jdbc-connector/blob/master/eth-jdbc-examples/src/main/java/com/impetus/blkchn/eth/Insert.java) for quick start

To use Ethereum JDBC connector in a maven project, add the following maven dependency in your project:

 

  

  ```

  

    com.impetus.eth

    eth-jdbc-driver

    ${ethjdbcdriver.version}

  

  ```

Build your project with the above changes to your pom.xml.
