== Try It! Pulling data from other tables

Lets try to exploit a join to another table.  One of the tables in the WebGoat database is:

-------------------------------------------------------
CREATE TABLE user_system_data (userid int not null primary key,
			                   user_name varchar(12),
			                   password varchar(10),
			                   cookie varchar(30));
-------------------------------------------------------

*6.a)* Execute a query to union or join these tables.  +
*6.b)* When you have figured it out.... What is Dave's password?
