The article offers key constraints on railroads in Great Britain pointed out by Steer Davies Gleave. He notes that the sharing of routes between express, semi-fast and local passenger services and freight constrains the timetable and could result in extended journey times. He emphasizes that there...
It is important to understand that there exists no significant difference between a primary key or unique key constraint and a unique index. To implement the concept of primary and unique key constraints, the database manager uses a combination of a unique index and the NOT NULL constraint. The...
SQL Server Primary Key Constraints SQL Server主键约束定义唯一约束,同时也会创建一个唯一索引(Unique index),同时这个字段不允许有NULL值存入。 一个表中,只能定义一个主键约束,一旦定义了主键,那它就自动拥有UNIQUE的唯一约束。 下面是在创建表时,定义主键:...
