SQL Server 2012：关键字“order”附近的语法不正确

Question

运行此查询时出现此错误...

select *, stuff(PartNumber,1,3,'') 
from products.products 
where  isnumeric(stuff(partNumber,1,3,'') 
order by cast(Stuff(partNumber,1,3,'')As Float)

有什么想法吗？

谢谢！

Answer 1

where声明不完整：

where  isnumeric(stuff(partNumber,1,3,'')) = 1
-----------------------------------------^

Answer 2

看起来你错过了一个括号：

此：

where  isnumeric(stuff(partNumber,1,3,'') 

应该是：

where  isnumeric(stuff(partNumber,1,3,'')) 

Answer 3

首先是缺少闭括号“）”，另一个是当输入表达式求值为有效数值数据类型时，必须在where子句中指定isnumeric返回1。

   `    select *, stuff(PartNumber,1,3,'') 
        from products.products 
      where  isnumeric(stuff(partNumber,1,3,'')) =1
     order by cast(Stuff(partNumber,1,3,'') As Float)
  `
