How to update a single column with multiple data in oracle 12c
1
I am updating an oracle table, same column with multiple data. How do i write the code?
I run this code but had error..
I am replacing Boy with Girl, Black with White and Green with Color.
UPDATE BIG
SET
FNAME = CASE
WHEN FNAME = 'BOY' THEN 'GIRL'
WHEN FNAME = 'BLACK' THEN 'WHITE'
WHEN FNAME = 'GREEN' THEN 'COLOR'
END;
I need to be able to write a single statement that can update same column with different and multiple data.

You need to handle ELSE(all rows will be updated some using A -> A (identity):
UPDATE BIG
SET
FNAME = CASE FNAME
WHEN 'BOY' THEN 'GIRL'
WHEN 'BLACK' THEN 'WHITE'
WHEN 'GREEN' THEN 'COLOR'
ELSE FNAME
END;
or better filter rows you want to update:
UPDATE BIG
SET
FNAME = CASE
WHEN FNAME = 'BOY' THEN 'GIRL'
WHEN FNAME = 'BLACK' THEN 'WHITE'
WHEN FNAME = 'GREEN' THEN 'COLOR'
END;
WHERE FNAME IN('BOY', 'BLACK', 'GREEN');
<=>
UPDATE BIG
SET FNAME = DECODE(FNAME, 'BOY', 'GIRL', 'BLACK', 'WHITE', 'GREEN', 'COLOR')
WHERE FNAME IN('BOY', 'BLACK', 'GREEN');
