         We have an if condition in programming sector to handle the conditional operation. Like that in SQL conditional operation done by using CASE statement. A sample example of CASE statement in sql is given below,

       syntax,


    SELECT CASE ("column_name") 
    WHEN "value1" THEN "result1"
    WHEN "value2" THEN "result2"
        ...
       [ELSE "resultN"]
     END
    FROM "table_name";

    eg:

         SELECT Store_Name, CASE Store_Name
          WHEN 'Los Angeles' THEN Sales * 2
          WHEN 'San Diego' THEN Sales * 1.5
          ELSE Sales
          END
          "New Sales",
          Txn_Date
          FROM Store_Information;
