SQL DISTINCT

SQL > SQL Commands > Distinct

The SELECT keyword allows us to grab all information from a column (or columns) on a table. This, of course, necessarily means that there will be redundancies. What if we only want to select each DISTINCT element? This is easy to accomplish in SQL. All we need to do is to addDISTINCT after SELECT. The syntax is as follows:

SELECT DISTINCT "column_name"
FROM "table_name";

For example, to select all distinct stores in Table Store_Information,

Table Store_Information

Store_Name	Sales	Txn_Date
Los Angeles	1500	Jan-05-1999
San Diego	250	Jan-07-1999
Los Angeles	300	Jan-08-1999
Boston	700	Jan-08-1999

we key in,

SELECT DISTINCT Store_Name FROM Store_Information;

Result:

Store_Name

Los Angeles

San Diego

Boston
