C＃（MS Access）中FROM子句中的語法錯誤

Question

從MS Access數據庫訪問數據時，from子句中出現語法錯誤，但是如果我在Access中運行相同的查詢，則會得到所需的結果，而不會發生任何錯誤。

任何幫助表示贊賞。 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";

我將您的字符串語句放入了Instant SQL Formatter中

並得到這個

看來您為每個聯接創建了一個內聯視圖。

從語法上看，對我來說不錯，但是Access可能不喜歡它。 當您僅可以使用標准聯接時，這是一種非常低效的聯接方式

您在JOIN子句的括號中缺少了一些空格。 不過，我不確定這是否是問題。
