SLQLite '更新中にエラーが発生しました。 'constraint failed' '

Question

8時間試していますが、間違っている部分はありません。私は最後のレコードを試したので、IDの問題が分かっています。それはID 5であるはずですが、NSlogは代わりに6を示します。 すべての一意のIDを削除しました。予約キーの問題ではありません。

ありがとうございます。

助けてください、私は狂っ........

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); 

あなたは最初のものはaddStmtことsouldことを確認してくださいていますか？

は、それはそれを示すコードで使われています のみ場所だ、とはっきり8つの updateStmt変数を移入するために設計されたセクションでは、私はそれが最も可能性が高いタイプミスやカットアンドペーストのエラーだと言うだろうと考えます。
