ошибка преобразования varchar для float ms sql

Question

Я получаю вышеуказанную ошибку в этом SP. (Хранилище таблиц) Столбцы MaxWeight, Высота, Ширина, & Глубина - поплавок. Есть идеи?

Answer 1

ваши isnulls должны быть поплавки не «» пустые строки

(ISNULL(Height,0.0)+ 'x' + ISNULL(Width,0.0) + 'x' + ISNULL(Depth,0.0)) As Dimension 

Я хотел бы проверить ваши другие isnulls, а также убедитесь, что они возвращают тип значения вы хотите.
