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 which will give me the direct result
SELECT
CASE
WHEN FRUIT = 'A' THEN FRUIT ='APPLE'
ELSE WHEN FRUIT ='B' THEN FRUIT ='BANANA'
FROM FRUIT_TABLE;
But I'm not getting the correct result, please help me..
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).
Try this.
SELECT
CASE
WHEN FRUIT = 'A' THEN 'APPLE'
WHEN FRUIT = 'B' THEN 'BANANA'
ELSE 'UNKNOWN FRUIT'
END AS FRUIT
FROM FRUIT_TABLE;
Change to:
SELECT
CASE
WHEN FRUIT = 'A' THEN 'APPLE'
WHEN FRUIT = 'B' THEN 'BANANA'
END
FROM FRUIT_TABLE;
which platform ?
SELECT
CASE
WHEN FRUIT = 'A' THEN 'APPLE'
ELSE FRUIT ='B' THEN 'BANANA'
END AS FRUIT
FROM FRUIT_TABLE;
