This topic describes how you can add RDBMS datasources to your data service. RDBMS datasources are used to service enable data from a relational database. 

Note that the instructions given here explains how to create RDBMS datasources that are specific to the data service. Alternatively, RDBMS datasources can be defined for your server using the instructions given here, which you can add to any data service as a Carbon datasource.

Follow the steps from 1 to 3 in creating a data service using various data sources to get the Add New Data Source screen shown below. Then, select RDBMS as the datasource type, to open the RDBMS-specific options as shown below: 

The options in the above window are described below:

datasource type

There are two types of RDBMS datasources as follows:

  • Default
    For the default type, connection properties such as driver class, URL and credentials must be entered as shown in the example above.

  • External datasource
    If you need to add a datasource supported by an external provider class such as com.mysql.jdbc.jdbc2.optional.MysqlXADataSource, select the external option and enter the name and value of connection properties by clicking Add Property. For example,
    After an external datasource is created, it can be used as a usual datasource in queries.

Database engine

The database management system. In the above example, we take MySQL.

Driver class/URL

Depending on the database engine, copy the relevant JDBC driver to the <PRODUCT_HOME>/repository/components/lib directory. For example, cp mysql-connector-java-5.XX-bin.jar /home/user/wso2ds/wso2-dataservices-XX/repository/components/lib.

If the driver class does not exist in the relevant folders when you create the datasource, you get an exception. For example, 'Cannot load JDBC driver class com.mysql.jdbc.Driver'.

Use as secret alias
