Oracle SQL Developer is a very powerful open source SQL development tool, but recently I began to study it, just installed Oracle SQL Developer is not supported to connect MySQL, need to download the JDBC driver formysql from the MySQL official website.
Oracle SQL Developer Official website:
Http://www.oracle.com/technetwork/cn/developer-tools/sql-developer/downloads/index.html
JDBC for MySQL official website:
http://www.mysql.com/downloads/connector/j/
The file name is roughly mysql-connector-java-5.1.18.zip, extracted after the download is complete, extract the Mysql-connector-java-5.1.18-bin.jar file, and put it in sqldeveloper\ Under the Jlib directory, then start Oracle SQL Developer, click menu tools->preferences, locate Database->third party JDBC Drivers, click Add Entry. : To create a MySQL connection, load the Mysql-connector-java-5.1.18-bin.jar file just now .
