Я пишу начало SP для SQL-сервера, используя несколько операторов case и temp-таблиц с условным аргументом else else в конце, чтобы вычесть значения друг от друга на основе условное дело else.Microsoft SQL server CASE ELSE CASE не закрывается справа
Все работает нормально, пока не дойду до условного случая else, где по какой-то причине END не совсем прав.
Как вы можете видеть из инструкции условного case else, только одна синтаксическая ошибка в скобке после END.
Любые советы были бы весьма полезными.
Заранее спасибо.

Спасибо за помощь Гордон, оценить его. Также очень хорошая точка о одиночных кавычках. Лень с моей стороны. –
