iphone-sqlite3数据库锁定异常

我试过很多方法，为了摆脱这个错误，但是我没有成功。我是一个新手，我试图找出所有其他问题，并尝试了一些建议，但它没有奏效。iphone-sqlite3数据库锁定异常

下面是代码：

- (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); 
    }

如果我用这个这个方法结束

} 
else sqlite3_finalize(addStmt); 

sqlite3_close(database); 
}

然后我的错误看起来是这样的：

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

如果我使用这个

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

我变得糟糕线程1：

编辑：我解决了我的问题很容易。

我没有最终确定和关闭插入，更新，删除的方法中的数据库，我只是重置语句，然后使其为零。在此之后，我宣布一个方法finalize，在那里我关闭数据库并最终确定语句。也许这个想法会帮助某人。

，请复制粘贴UR错误 – 2013-02-20 08:34:43

你在一个循环中调用-addObiectAsigurat？ – Oleg 2013-02-20 08:53:54

@Oleg是的。在for循环中。我想从nsdictionary中插入对象。 – 2013-02-20 09:03:08

确保您在使用它的其他方法中关闭数据库连接。

既然你打电话给你的方法在一个循环中，有更有效的方式与数据库的工作，当你需要数据的批量插入：通过你的价值观重建您的应用程序循环内INSERT这样的：这只是举例来说，在这里插入正确的价值观

-(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); 
}

谢谢你的回答。我会尝试你的方式。 :) – 2013-02-20 09:25:45

一种可能性是，你是不是犯插入事务。搜索如何提交并尝试一些解决方案。

以下可帮助

SQLite 3 C API Transactions

忽略，如果你已经尝试过....

他正在做一个INSERT，没有TRANSACTIONs所以没有必要使用COMMIT那里:-) – Oleg 2013-02-20 08:53:20
