Question 1 – Table Selection in SQL
Question 1: Select the Products table from the 'Base' Database.

In MySQL and in data management programs in general, we can view the list of databases on the left side. By clicking on the database, we can see all the tables present in it.

Database
Selecting our Products table from this database is simple. First, we make sure the database is active. To do this, we right-click on the database name and select “ Set Default Schema ”.

Set Default Schema
Then, we use the SELECT command (can be written in upper or lower case), followed by an asterisk and the table name:

SELECT * FROM produtos
This way, we are selecting all the content of the products table, which will be displayed in our results.

Table
Another way to solve this issue without having to define the database manually is to declare the database name in the code before the table name.
