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 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 calls to connect to Ethereum. The driver then converts the returned objects to a JDBC compliant result set and return it to the user.

Tested with

Features Added with Release 1.1.0

• Smart contract support -User can deploy smart contract and run its fuctions by using jdbc driver
• Ethereum with Spark
• Batch Transaction- Initiating multiple transactions in a batch

Building ethereum-jdbc-connector

• Download 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 sourcecode or use git clone https://github.com/Impetus/eth-jdbc-connector.git
• build it using mvn clean install

Getting Started

• Navigate to examples folder
• Run Query.java and Insert.java for quick start

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

<dependency>   <groupId>com.impetus.eth</groupId>   <artifactId>eth-jdbc-driver</artifactId>   <version>${ethjdbcdriver.version}</version> </dependency> 

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

简介

加入谷歌集团

以太坊ethJDBC驱动程序实现了一个纯java类型4 JDBC驱动程序，在以太坊eth区块链blockchain上执行SQL查询。它有助于以JDBC兼容的方式从以太坊eth获取数据。以太坊ethJDBC驱动程序可用于使用熟悉的SQL语言执行ETL、BI报告和分析。

它使用blkchn sql驱动程序解析查询并创建相应的逻辑计划。然后，该逻辑计划将转换为优化的物理计划。驱动程序使用相应的web3j调用来扩展和实现物理计划，以连接到以太坊eth。然后，驱动程序将返回的对象转换为JDBC兼容的结果集，并将其返回给用户。

测试的

添加了1.1.0版的功能

• 智能合约支持-用户可以使用jdbc驱动程序部署智能合约并运行其功能
• Ethereum with Spark
• 批量事务启动多个事务

构建以太坊ethjdbc连接器

• 下载或克隆blkchn sql驱动程序项目git clonehttps://github.com/pulse/blkchn-sql-driver.git
• 使用mvn clean install-Pgen源代码构建blkchn sql驱动程序
• 下载源代码或使用git clonehttps://github.com/pulse/eth-jdbc-connector.git
• 使用mvn clean install构建它

入门

• 导航到examples文件夹
• Run查询.java以及插入.java要快速启动，请检查如何连接以太坊eth

要在maven项目中使用以太坊ethJDBC连接器，请在项目中添加以下maven依赖项：

<dependency>   <groupId>com.impetus.eth</groupId>   <artifactId>eth-jdbc-driver</artifactId>   <version>${ethjdbcdriver.version}</version> </dependency> 

使用对pom.xml文件.
