Это устаревший запрос, который я очищаю, и я смущаюсь с этим аргументом case, поэтому любая помощь будет принята с благодарностью.T-SQL Case Statement confusion
SELECT CASE
WHEN bitdelivered = 1 THEN
'' + CONVERT(CHAR(10), deliv.dtmdeliverydate, 101)
+ ' '
+ 'þ' + '
' -- this is a carriage return, do not remove it
WHEN bitdelivered = 0 AND deliv.dtmdeliverydate < Getdate() THEN
'' + CONVERT(CHAR(10), deliv.dtmdeliverydate, 101)
+ ' '
+ '¨' + '
'
ELSE
'' + CONVERT(CHAR(10), deliv.dtmdeliverydate, 101)
+ ' '
+ '¨' + '
'
END
Как я сказал, что это очень грязная, но когда я запускаю весь запрос, если я получаю 0 для bitdelivered, то casestatement работает как следует, однако, если я получаю 1 вернулся, то я возвращаю null вместо блока else. Есть идеи?
EDIT Я редактировал код, как показано ниже, для облегчения читаемости и я все еще получаю пустой ...
select
CONVERT(CHAR(10), deliv.dtmdeliverydate, 101) +
' ' +
CASE
WHEN bitdelivered = 1 THEN 'þ'
ELSE '¨'
END + '
'
EDIT х 2 Здесь все (очень противным я знаю) SQL-запрос Я не пишу это, я просто пытаюсь очистить его ...

Возможно ли, что 'deliv.dtmdeliverydate' является NULL? Я бы надеялся, что с тех пор, как ваш бит-бит будет равен 1 в этом случае. –
