ERROR 1217 (23000): Cannot delete or update a parent row: a foreign key constrain fails。

可能是MySQL在InnoDB中設置了foreign key關聯，造成無法更新或刪除數據。可以通過設置FOREIGN_KEY_CHECKS變量來避免這種情況。

1、set foreign_key_checks=0;

2、刪除要刪除的表;

3、set foreign_key_checks=1;

在MySQL 3.23.44版本後，InnoDB引擎型別的表支援了外來鍵約束。外來鍵的使用條件： 1.兩個表必須是 InnoDB表，MyISAM表暫時不支援外來鍵（據說以後的版本有可能支援，但至少目前不支援）； 2.外來鍵列必須建立了索引，MySQL 4.1.2以後的版

其實這句話的意思就是你新增一個值是一個外來鍵，但是這個外來鍵不在關聯的資料庫中的主鍵中，這樣就導致了新增失敗了，解決辦法就是新增對應關聯資料庫的主鍵的值，不過我要提醒一下！（也就是我採的坑！）一定要看清
