誤差變換數據類型爲varchar到數字和varchar爲datetime

Question

錯誤數據類型爲varchar轉換爲數字

一個char數據類型到datetime數據類型的轉換導致外的範圍內的日期時間值。

declare @rsnMain numeric, @rsnAcnt numeric, @rsnRel numeric; 
set @rsnMain = (select max(record_serial_number) 
       from sdg_aaismain) 
set @rsnAcnt = (select max(record_serial_number) 
       from sdg_aaisacnt) 
set @rsnRel = (select max(record_serial_number) 
       from sdg_aaisrel)

以上代碼是較長更新語句的示例。我有2列給我「錯誤轉換數據類型varchar數值」錯誤。這是因爲有些記錄有字符數據。

超出範圍的錯誤發生在4個不同的varchar列上，日期都是'00000000'作爲某些行的值。

如何從我的選擇查詢中排除字符數據和零點？

感謝， 斯科特

如果要完全排除該行，那麼你可以做：

WHERE ISDATE(someColumn)=1 

如果你想此行，但是駕駛零到日期即可做：

INSERT INTO someTable (datecolumn) 
SELECT CASE WHEN ISDATE(someColumn)=1 THEN CONVERT(DATETIME,someColumn) ELSE NULL END 
FROM someOtherTable
