how to execute multiple query in single database connection ?

I have created a test for the following

a. Add a name
b. Send an email

I need to verify the values against the database.  I have written two queries one for getting the name and other for getting the email id from the database.  In Coded step i have given the connection string and executed one query (retrieving a name).  To get the email id (retrieving an email) do i need to declare connection string again or add another coded step?  Both tables are in the same database.
