Question

有没有办法在SQL 2014中获取插件上发生错误的字段名称。我插入了30多个字段，并且浪费了数小时试图找出错误发生的位置。看起来像一个简单的调试功能，但我得到的错误是

Msg 8114，Level 16，State 5，Line 2

将数据类型nvarchar转换为数字时出错。

我已经通过插入表中的每个数字列，并尝试将相应的数据转换为正确的数据类型，但无法找到问题。

解决问题的最佳方法是使用ISNumeric函数

检查字段

SELECT ID, field1, field2 .., fieldN
FROM yourTable
WHERE 
     ISNUMERIC(field1) = 0
OR   ISNUMERIC(field2) = 0
...
OR   ISNUMERIC(fieldN) = 0

如果您使用INSERT进行CASE尝试并将其更改为默认值。

INSERT INTO YourTable
Values (
      CASE 
          WHEN ISNUMERIC(field1) = 0 THEN -999
          ELSE CAST (field1 as numeric) 
      END as field1,
      CASE 
          WHEN ISNUMERIC(field2) = 0 THEN -999
          ELSE CAST (field2 as numeric) 
      END as field2,
      ...

然后搜索YourTable -999

我知道并不是很好，但是要做好这份工作。
