iphone-sqlite3數據庫鎖定異常

我試過很多方法，爲了擺脫這個錯誤，但是我沒有成功。我是一個新手，我試圖找出所有其他問題，並嘗試了一些建議，但它沒有奏效。iphone-sqlite3數據庫鎖定異常

下面是代碼：

- (void) addObiectAsigurat 
{ 
sqlite3 *database = nil; 
sqlite3_stmt *addStmt = nil; 

if(sqlite3_open([[Database getDBPath] UTF8String], &database) == SQLITE_OK) 
{ 

    if(addStmt == nil) { 
     const char *sql = "INSERT INTO ObiectAsigurat (IdIntern, TipObiect, JSONText) Values(?, ?, ?)"; 
     if(sqlite3_prepare_v2(database, sql, -1, &addStmt, NULL) != SQLITE_OK) 
      NSAssert1(0, @"Error while creating add statement. '%s'", sqlite3_errmsg(database)); 
    } 

    sqlite3_bind_text(addStmt, 1, [IdIntern UTF8String], -1, SQLITE_TRANSIENT); 
    sqlite3_bind_int(addStmt, 2, TipObiect); 
    sqlite3_bind_text(addStmt, 3, [JSONText UTF8String], -1, SQLITE_TRANSIENT); 


    if(SQLITE_DONE != sqlite3_step(addStmt)) 
     NSAssert1(0, @"Error while inserting data. '%s'", sqlite3_errmsg(database)); 
    else { 
     sqlite3_finalize(addStmt); 
     sqlite3_close(database); 
    }

如果我用這個這個方法結束

} 
else sqlite3_finalize(addStmt); 

sqlite3_close(database); 
}

然後我的錯誤看起來是這樣的：

Assertion failure in -[YTOObiectAsigurat addObiectAsigurat] 
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Error while inserting data. 'database is locked'' 
*** First throw call stack:

libc++abi.dylib: terminate called throwing an exception

如果我使用這個

sqlite3_finalize(addStmt); 
    } 
sqlite3_close(database); 
}

我變得糟糕線程1：

編輯：我解決了我的問題很容易。

我沒有最終確定和關閉插入，更新，刪除的方法中的數據庫，我只是重置語句，然後使其爲零。在此之後，我宣佈一個方法finalize，在那裏我關閉數據庫並最終確定語句。也許這個想法會幫助某人。

你在一個循環中調用-addObiectAsigurat？ – Oleg 2013-02-20 08:53:54

@Oleg是的。在for循環中。我想從nsdictionary中插入對象。 – 2013-02-20 09:03:08

確保您在使用它的其他方法中關閉數據庫連接。

既然你打電話給你的方法在一個循環中，有更有效的方式與數據庫的工作，當你需要數據的批量插入：通過你的價值觀重建您的應用程序循環內INSERT這樣的：這只是舉例來說，在這裏插入正確的價值觀

-(void)insertValuesFromArray:(NSMutableArray *)array { 

sqlite3 * database; 

const char *dbpath = [[Database getDBPath] UTF8String]; 

if (sqlite3_open(dbpath, &database) == SQLITE_OK) 
{ 
    sqlite3_exec(database, "BEGIN TRANSACTION", 0, 0, 0); 
    const char *sqlStatement = "INSERT INTO ObiectAsigurat (IdIntern) Values(?)"; 
    sqlite3_stmt *compiledStatement; 

    if (sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) { 
     int hasError = 0; 

     for (int i=0; i<[array count]; i++) { 
      sqlite3_bind_text(compiledStatement, 1, [[array objectAtIndex:i] UTF8String], -1, SQLITE_TRANSIENT); 


      if (sqlite3_step(compiledStatement) != SQLITE_DONE) { 
       hasError=1; 
       NSLog(@"Prepare-error %s", sqlite3_errmsg(database)); 
      } 

      sqlite3_reset(compiledStatement); 
     } 

     sqlite3_finalize(compiledStatement); 

     if(hasError == 0) { 
      sqlite3_exec(database, "COMMIT", 0, 0, 0); 
      NSLog(@"inserted successfully"); 
     } 
     else { 
      sqlite3_exec(contactDB, "ROLLBACK", 0, 0, 0); 
      NSLog(@"can't insert:"); 
     } 
    } 
    sqlite3_close(contactDB); 
}

謝謝你的回答。我會嘗試你的方式。 :) – 2013-02-20 09:25:45

一種可能性是，你是不是犯插入事務。搜索如何提交併嘗試一些解決方案。

以下可幫助

SQLite 3 C API Transactions

忽略，如果你已經嘗試過....

他正在做一個INSERT，沒有TRANSACTIONs所以沒有必要使用COMMIT那裏:-) – Oleg 2013-02-20 08:53:20
