​
Usage

A text example of usage of this handler and connect to DB2 in MindsDB can be seen below,

CREATE DATABASE DB2_datasource
WITH
engine='DB2',
parameters={
    "user":"db2admin",
    "password":"1234",
    "host":"127.0.0.1",
    "port":25000,
    "schema_name":"db2admin",
    "database":"BOOKS"
};

Now, you can use this established connection to query your database as follows,

SELECT * FROM DB2_datasource.AUTHORS;
