函數調用參數是一個未初始化的值？

我一直在試圖弄清楚爲什麼Xcode中的分析器似乎喜歡這個代碼，所以也許有人可以看到什麼是錯的。給我這個消息：「函數調用參數是一個未初始化的值」。函數調用參數是一個未初始化的值？

它有一個問題，這條線和抱怨的「聲明」：

if (sqlite3_exec(MysDB, delete_stmt, NULL, statement, NULL) == SQLITE_OK) {

實際代碼：

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { 
if (buttonIndex == 1) { 
    sqlite3_stmt *statement; 
    const char *dbpath = [databasePath UTF8String]; 

    if (sqlite3_open(dbpath, &MyDB) == SQLITE_OK) 
    { 
     NSString *deleteSQL = [NSString stringWithFormat:@"DELETE FROM DATATABLE WHERE ID = %d", recordID]; 

     const char *delete_stmt = [deleteSQL UTF8String]; 
     if (sqlite3_exec(MysDB, delete_stmt, NULL, statement, NULL) == SQLITE_OK) { 

      NSLog(@"Deleted");    
     }else{ 
      NSLog(@"Not Deleted"); 
     } 
     sqlite3_close(MyDB); 
    } 
}
