If you see the customer data returned, you have successfully imported the sample database into the MySQL database server. We will start by defining the primary components of this schema design. CAUTION: The first step in installing sample schemas is to drop user accounts with the... 3. The following query will generate two additional tables, and should constrain the data in all three. There’s a lot of confusion about schemas when it comes to databases. Good analytics is no match for bad data.
