问题描述

我正在查看Microsoft SQL Server Management Studio中的现有数据库，在数据库图中，有一个相对关系，以虚线或虚线显示。其他关系都是实线。虚线代表什么意思？

I'm looking at an existing database in Microsoft SQL Server Management Studio, and in the Database Diagram there is one relatioship that appears with a dashed or dotted line. The other relationships are all solid lines. What does the dashed line mean?

推荐答案

虚线/虚线表示SQL Server不强制此关系的引用完整性。查看此处

The dotted/dashed line means, that SQL Server does not enforce referential integrity for this relationship. Have a look here
