Which SQL statement is used to return only different values?


 

 

 

 



C


Solution:-

The SQL SELECT DISTINCT Statement
The SELECT DISTINCT statement is used to return only distinct values or different values. Inside a table, the column frequently contains so many duplicate values; and sometimes you only want to list the different (distinct) values.

SELECT DISTINCT Syntax

SELECT DISTINCT column1, column2, ... FROM table_name;

 

SELECT DISTINCT Examples
The following SQL statement selects only the DISTINCT values from the "Courses" column in the "Slightbook" table,

SELECT DISTINCT Courses FROM Slightbook;
