SELECT using 'CASE' in SQL

Question

I have a set of one to one mappings A -> apple, B-> Banana and like that.. My table has a column with values as A,B,C..

Now I\'m trying to use a select statement whi

Answer 1

This is just the syntax of the case statement, it looks like this.

SELECT 
  CASE 
    WHEN FRUIT = 'A' THEN 'APPLE' 
    WHEN FRUIT = 'B' THEN 'BANANA'     
  END AS FRUIT
FROM FRUIT_TABLE;

As a reminder remember; no assignment is performed the value becomes the column contents. (If you wanted to assign that to a variable you would put it before the CASE statement).
