MySQL database with at least one table containing data.Ģ. Spark SQL Python and mySQL Setup Requirementsġ. We’ll make sure we can authenticate and then start running some queries. Then, we’re going to fire up pyspark with a command line argument to specify the JDBC driver needed to connect to the JDBC data source. We’re going to load some NYC Uber data into a database for this Spark SQL with MySQL tutorial. If you are brand new, check out the Spark with Python Tutorial.

But to run the JDBC programs, the JDBC driver's JAR-file must be included in the environment variable CLASSPATH, or in the java's command-line option -cp. You can compile Java database programs without the JDBC driver. The MySQL's JDBC driver is called "MySQL Connector/J" and is available at MySQL mother site.
#Mysql jdbc examples install#
You need to install an appropriate JDBC (Java Database Connectivity) driver to run your Java database programs. Install MySQL JDBC Driver ( IMPORTANT - Don't MISS This Step!) This step is important otherwise, you will be out-of-sync with this article and may not be able to find your files later. I shall assume that you have created a directory called " c:\myWebProject" (for Windows) or " ~/myWebProject" (for macOS) in your earlier exercises.

On MySQL, instead of using the " mysql" command-line client program provided, you can write your own client programs (in Java or other languages) to access the MySQL server. I shall assume that the MySQL server is running on the default TCP port number 3306. Install MySQL (Read " How to Set Up MySQL and Get Started"). For other database systems, read " Other Databases". In this article, I shall describe the MySQL Relational Database Management System. Otherwise, read " Introduction to Relational Database and SQL". I presume that you have some knowledge on Relational Databases and the SQL language. Relational Database and Structure Query Language (SQL)
