SQL Select Column

You can retrieve not all the data, but only some columns. For this, you should specify column name, for example, singer or title.

This query returns all the data containing in the title column:


              1
            
SELECT title FROM songs

You can also choose two or more columns:


              1
            
SELECT title, singer FROM songs

Now you selected all records from the table, but only title and singer columns.
