bookRetrieving All Columns

Instead of listing each column, you can use the asterisk * to retrieve all columns from the table at once. This is especially useful when you need to view all the data in a table without manually typing out each column name. Here’s an example:


              
12

            
SELECT * 
FROM table_name;
copy
