SLQLite'更新時出錯。 '約束失敗''

Question

已經嘗試了8個小時，不太確定哪個部分出了問題。我知道是我試過最後一張唱片時的ID問題。它應該是ID 5，但是NSlog顯示6。 我刪除了所有的唯一ID，所以不保留關鍵問題。

感謝您的期待。

請幫幫忙，我快瘋了........

Answer 1

sqlite3_bind_text(addStmt, 1, [TypeName UTF8String], -1, SQLITE_TRANSIENT); 
sqlite3_bind_text(updateStmt, 2, [DateStr UTF8String], -1, SQLITE_TRANSIENT); 
sqlite3_bind_text(updateStmt, 3, [Location UTF8String], -1, SQLITE_TRANSIENT); 
sqlite3_bind_text(updateStmt, 4, [GeoCode UTF8String], -1, SQLITE_TRANSIENT); 
sqlite3_bind_text(updateStmt, 5, [Note UTF8String], -1, SQLITE_TRANSIENT); 

您肯定是第一個被前人的精力addStmt？

鑑於這就是它在所示的代碼中使用的只有的地方，在顯然是爲了填充八個updateStmt變量一節，我會說這是最有可能的一個錯字或剪切和粘貼錯誤。
