我怎样才能null在上面的语句中添加一个,因为我正在使这个字段自动增加.

    for (int i =0 ; i < [jsonArray count]; i++) 
    // while (i < [jsonArray count])
{ 
 dictionary = [jsonArray objectAtIndex:i];
 char *errorMsg;

 sqlite3_stmt *statement;
 if(sqlite3_prepare_v2(database, [insertQuery UTF8String], -1, &statement, nil) == SQLITE_OK) 
 {
 // NSLog(@"%@",[dictionary valueForKey:@"text"]);
 sqlite3_bind_null(statement, 1);
 sqlite3_bind_text(statement, 2, [[dictionary valueForKey:@"date"] UTF8String], -1, NULL);
    // NSLog(@"date %@",[dictionary valueForKey:@"date"]);

 sqlite3_bind_text(statement, 3, [[dictionary valueForKey:@"text"] …
