Answer 1

好的，检查有几个问题。

1 - 您不应将数字与字符串进行比较，以便

  HOLIDAY_MULTIPLIER <='1.00' and >='3.50'

应该是：

  HOLIDAY_MULTIPLIER <=1.00 and  >=3.50

2 - Sintaxis错误，你不能以这种方式写条件，你需要：

  HOLIDAY_MULTIPLIER <=1.00 and HOLIDAY_MULTIPLIER >=3.50

3 - 范围没有意义，因为HOLIDAY_MULTIPLIER不能同时小于1且大于3.50，所以你需要反转<=或使用{{ 1}}

OR

最后，您可以使用HOLIDAY_MULTIPLIER >=1.00 and HOLIDAY_MULTIPLIER <=3.50代替

between

Answer 2

HOLIDAY_MULTIPLIER BETWEEN 1.00 and 3.50 =＆gt; HOLIDAY_MULTIPLIER <='1.00' and >='3.50'

使用数字文字而不是字符串 - HOLIDAY_MULTIPLIER <='1.00' and HOLIDAY_MULTIPLIER >='3.50'

在oracle中挣扎的表达缺失
