MySql查詢創建的所有表，但有一個錯誤1146

Question

我有一個mySql查詢來爲類寫入，但我得到錯誤1146，客戶表不存在，我的客戶表。我修復了所有其他問題，但無法看到客戶表的問題。這裏是我的代碼：

同樣，除非我沒有看到的東西，似乎所有表和刀片是設置類似，但客戶卻似乎不存在。爲什麼它不創建表或存在？任何幫助是極大的讚賞。

Answer 1

您試圖在創建Location表之前在Customer中創建引用Location表的外鍵。

語句SET FOREIGN_KEY_CHECKS=0爲您提供了一些靈活性，例如您可以加載所引用父表的數據值尚未具有相同值的數據值。這允許用循環引用加載數據。

但是它不允許您在FK約束中引用表，如果該表尚不存在。

將FK約束的所有定義推遲到腳本末尾是正常的。在創建完所有表後，使用ALTER TABLE將FK約束添加到表中。

Answer 2

用不存在的東西創建鏈接。那是位置表...
