在C＃中的FROM子句中的語法錯誤（MS Access）

我在從子句中訪問數據時從MS Access數據庫中的語法錯誤但如果我在訪問中運行相同的查詢我得到所需的結果沒有任何錯誤。在C＃中的FROM子句中的語法錯誤（MS Access）

任何幫助表示讚賞。這是我的代碼

string strQuery = string.Empty ; 


      strQuery = "SELECT TUCLRII.LUSID,TUCLRII.UserID,TUCLRII.LastName,TUCLRII.FirstName,TUCLRII.MI,TUCLRII.Sex,TUCLRII.WhichEye,TUCLRII.Memo1,TUCLRII.Memo2,TUCLRII.CreationDT, TUCLRII.LastModifiedDT,TUCLRII.CardID,TUCLRI.UCID,TUCLRII.WiegandData,TUCLRII.LIrisCodeID,TUCLRII.LWhichEye,TUCLRII.LIrisCode,TUCLRII.RIrisCodeID,TUCLRII.RWhichEye,TUCLRII.RIrisCode,TUCLRII.LIrisImage,TUCLRII.LImageFormat,TUCLRII.LImageSize,TUCLRII.LWhichEye,TUCLRII.RIrisImage,TUCLRII.RImageFormat,TUCLRII.RImageSize,TUCLRII.RWhichEye,TIM.ImageFormat,TIM.ImageSize,TIM.FaceImage,TIM.PictureTakenDT";

多個FROM子句？ – 2011-05-17 06:41:38

@ Will A：是的...... – user662285 2011-05-17 06:55:23

你錯過了在JOIN子句括號周圍的一些空間。不過，我不確定這是否是問題。

我把你的字符串陳述，放入Instant SQL Formatter

，並得到這個

這樣看來，你創造了每加入一個內嵌視圖。

句法上看起來很好，但也許Access不喜歡它。當你可以使用標準連接時，它是一種非常低效的加入方式
