您可以删除逗号，然后将值转换为数字数据类型：
DECLARE @Number VARCHAR(50); SET @Number = '-128,533.74'; SELECT CONVERT(DECIMAL(16,4),REPLACE(@Number,',',''))You can remove the comma and then convert the value to a numeric data type:
DECLARE @Number VARCHAR(50); SET @Number = '-128,533.74'; SELECT CONVERT(DECIMAL(16,4),REPLACE(@Number,',',''))

至少在.NET中，数字格式与文化有关，而不是符号。 默认货币符号是与该文化相关的主要货币符号。 符号可以根据需要重写。 就像你的例子一样，如果我在一个字符串中嵌入一个货币值，那么我使用该字符串的文化作为格式，但是适当地覆盖货币符号。 其余格式保持原样。 另一方面，如果我正在做一个报告，所有的值都使用相同的文化进行格式化。 在这种情况下，我通常使用ISO 3字符代码而不是货币符号，尤其是涉及超过2种货币时，以避免字体问题。 Ryan对另一个问题的回答描述了C＃中货币格式化的最佳实践。 At least in ...
