Обсуждение: deleting multiple rows

A very simple SQL question, LOL.

If I want to delete multiple rows, I can use '||' to do it like this, right?

DELETE FROM TableName
WHERE
    column = value1 ||
    column = value2 ||
    column = value4 ||
    column = value5
;

|| is generally concatenate.  You'll want to use OR.

Wrong!

 || is for string concatenation.

Possibly you mean:

  WHERE column = value1 OR column = value2 OR ...

As others have pointed out '||' is concatenation, you are looking for
'OR'.
But possibly a nicer way is '... WHERE column IN (value1, value2,
value4, value5);'
