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.
Show quoted text
DELETE FROM TableName
WHERE
column = value1 ||
column = value2 ||
column = value4 ||
column = value5

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);'
