目前，我正在执行以下查询并收到上述错误消息：

SELECT dbo.qryOtherFieldDataVerifySource.ItemID,
       dbo.qryOtherFieldDataVerifySource.EDGRDataID,
       dbo.qryOtherFieldDataVerifySource.LineItemID,

       CASE
         WHEN DataTypeID = '{5951994B-BF47-4117-805D-B8F85FAB76A8}'
              AND ISNUMERIC(DataValue) = 1 THEN ( CASE
                                                    WHEN CAST(DataValue AS FLOAT(8)) >= 0 THEN 1
                                                    ELSE 0
                                                  END )
         ELSE 0
       END AS ValidPositiveNumericValue,
       CASE DataTypeID

         WHEN '{5951994B-BF47-4117-805D-B8F85FAB76A8}' THEN ISNUMERIC(DataValue)
         ELSE 1
       END AS ValidDataType,
       dbo.tblZEGCode.ZEGCode,
       dbo.qryOtherFieldDataFieldName.FieldName
FROM   dbo.qryOtherFieldDataVerifySource
       LEFT OUTER JOIN dbo.qryOtherFieldDataFieldName
         ON dbo.qryOtherFieldDataVerifySource.ItemID = dbo.qryOtherFieldDataFieldName.ItemID
       LEFT OUTER JOIN dbo.tblBC
                       RIGHT OUTER JOIN dbo.tblZEGCode
                         ON dbo.tblBC.BCID = dbo.tblZEGCode.BCID
         ON dbo.qryOtherFieldDataVerifySource.ZEGCodeID = dbo.tblZEGCode.ZEGCodeID

有没有人有什么建议？

我建议寻找阻止您转换为 float 类型（又名真实）的错误值，并e0在测试之前使用连接到该值的技巧：

SELECT *
FROM dbo.YourTable
WHERE
   DataTypeID = '{5951994B-BF47-4117-805D-B8F85FAB76A8}' -- the type for float
   AND IsNumeric(
      DataValue + CASE WHEN DataValue NOT LIKE '%[ed]%' THEN 'e0' ELSE '' END
   ) = 0
   AND IsNumeric(DataValue) = 1
;

这适用于 SQL Server 2000 及更高版本。

更新1：由于您分享了您只想找到那些不容易检测到的，而不是所有那些不是真正数字的，我添加了第二个IsNumeric。

更新2：你终于告诉我你的一些价值观已经有了科学记数法。这很容易处理。我已经更新了上面的查询。请试穿尺寸。

对于使用 SQL Server 2012 或更高版本的任何人，此问题可能最好使用TRY_PARSE解决：

SELECT TRY_PARSE(Value AS float)

这会将任何值转换为可能的浮点数，但会为其他任何值返回 NULL。因此，您可以使用它来检查转换为浮点数是否会失败，方法是检查这个表达式IS NULL。

试试这个——

SELECT
      s.ItemID
    , s.EDGRDataID
    , s.LineItemID
    , s.ZEGCodeID
    , s.DataValue
    , t.AcceptableValues
    , s.DataUnitID
    , s.DataDate
    , t.DataTypeID
    , ValidPositiveNumericValue =
        CASE WHEN DataTypeID = '{5951994B-BF47-4117-805D-B8F85FAB76A8}' AND ISNUMERIC(DataValue) = 1 
            THEN CASE WHEN CAST(DataValue AS FLOAT(8)) >= 0 THEN 1 ELSE 0 END
            ELSE 0
        END
    , ValidDataType =
       CASE 
        WHEN DataTypeID = '{A6317BA5-F8FB-4866-A26B-24594650C2DC}'
            THEN CASE WHEN UPPER(DataValue) IN ('TRUE', 'FALSE', 'YES', 'NO', 'Y', 'N', '0', '1') THEN 1 ELSE 0 END 
        WHEN DataTypeID = '{5951994B-BF47-4117-805D-B8F85FAB76A8}' 
            THEN ISNUMERIC(DataValue)
         ELSE 1
       END
    , c.ZEGCode
    , f.FieldName
FROM dbo.qryOtherFieldDataVerifySource s
LEFT JOIN dbo.qryOtherFieldDataFieldName f ON s.ItemID = f.ItemID
RIGHT JOIN dbo.tblZEGCode c ON s.ZEGCodeID = c.ZEGCodeID
LEFT JOIN dbo.tblBC t ON t.BCID = c.BCID

创建了以下游标以使查询一次执行一行，这使我能够识别问题数据行：

SET ARITHABORT OFF
SET ARITHIGNORE ON
SET ANSI_WARNINGS OFF

    DECLARE @itemid AS NVARCHAR(255);

    SELECT ItemID AS itemid

FETCH NEXT FROM C INTO @itemid;

WHILE @@fetch_status = 0
