My SQL Workbench Error 1452 - 无法创建源表

【问题标题】：My SQL Workbench Error 1452-source table cannot be createdMy SQL Workbench Error 1452 - 无法创建源表
【发布时间】：2015-10-19 02:13:47
【问题描述】：

在生成源表时无法弄清楚是什么问题。 ins_id 似乎是导致问题的原因。它是自动增量，所以我将其保留为空，机构表中的其他所有内容都与源表中的相同。这是代码。

    【解决方案1】：

    在插入“源”表时，“ins_id”列必须在“institution”表的“ins_id”列中已经存在一个值..... DEFAULT 不在这里提供

    【讨论】：

      【解决方案2】：

      您似乎正在为institution 表的ins_id 列使用AUTO_INCREMENT。

      因此，您的第一个机构的值为 1，然后是第二个机构的 ID 为 2，依此类推。

      但是当您插入source 表时，您使用DEFAULT 表示ins_id，它的值将是0。

      因此，外键约束失败。

      【讨论】：

      • 那么，你建议我在机构表中做些什么来确保自动增量值进入源表？我应该更改代码中的某些内容还是更改源表列中的某些内容？我以前从未遇到过这个问题。
