我只想知道這個錯誤是什麼意思？ INSERT語句與FOREIGN KEY約束「FK__thumbnail__instr__160F4887」衝突。數據庫「MusicStoreDB」，表「dbo.instrumentItem」，列'instrumentId'發生衝突。 該聲明已被終止。asp.net中的服務器錯誤？
這裏是堆棧跟蹤：
Server Error in '/' Application.
The INSERT statement conflicted with the FOREIGN KEY constraint
"FK__thumbnail__instr__160F4887". The conflict occurred in database
"MusicStoreDB", table "dbo.instrumentItem", column 'instrumentId'.
The statement has been terminated.

異常消息是不言自明的。確保您存儲在instrumentItem表中的instrumentId是有效的（它應該存在於Instrument表中） – Shyju
您是否熟悉外鍵約束是什麼？這是在Google上查找的好用語。基本上錯誤是告訴你，你試圖插入一個值，只允許某些值的列（基於相關表中的值），並且你插入的內容不是允許的值之一（doesn在相關表格中不存在）。 – David
