Error in update statement, confused with insert? - sql

Question

UPDATE KopierenJPGs
SET(IdImage, Path, Date)
VALUES (115,'\fantasy\5.jpg', '22/02/2015 18:08:28')
WHERE IdImage = 30
And
WHERE Path = '\fantasy\6.jpg'
AND
WHERE Date = '22/02/2015 18:10:28'
I was taught to execute update statements like this, though not a single site gives this example.
It seems to me that my teacher confused an insert command with an update command?
Do I have it wrong here? Is there an actual error in this statement?
I am aware there are three where clauses, I need them for my program. I cannot update a fixed ID since the column names are variable, this is intentional.
Thank you.

Answer 1

I doubt your teacher made the confusion. Use the correct syntax for update:
UPDATE KopierenJPGs
SET IdImage = 115,
Path = '\fantasy\5.jpg',
Date = '2015-02-22 18:08:28'
WHERE IdImage = 30 And Path = '\fantasy\6.jpg' and Date = '2015-02-22 18:10:28';
Note that I also changed the date formats to ISO standard formats. You should use these in code to avoid ambiguity and future problems.

If you want to insert a new row, then yes instead of update you need insert statement like:
INSERT INTO KopierenJPGs (IdImage, Path, Date)
VALUES (115,'\fantasy\5.jpg', '22/02/2015 18:08:28')
If you want to update an already existing row, you could do something like:
UPDATE KopierenJPGs
SET IdImage = 115,
Path = '\fantasy\5.jpg',
Date = '22/02/2015 18:08:28'
WHERE IdImage = 30
AND Path = '\fantasy\6.jpg'
AND Date = '22/02/2015 18:10:28'
