Accessing Data with SELECT * in SQL 

What do we do if we want to access all columns in the table, not specific columns? Are we going to write all column names one by one? Of course not! We will use the above command structure again, but we will make a slight change. After the SELECT command, instead of writing the column names, we will put a * sign. With this sign, we will indicate that we want to access all columns. With the following command structure, we can access all columns in the table and the data in these columns.
