特别是在建表建存储过程的时候进场会写到: IF OBJECT_ID('Table_Test','U') IS NOT NULL DROP TABLE Table_Test 这种方式代替了以往所使用的 IF EXISTS (SELECT * FROM SYSOBJECTS WHERE NAME = 'Table_Test') DROP TABLE Table_Test 第一段代码中的 U 可以省略不写, 这样系统就会检索所有的对象名称以找到对应的ID, 但是写出来就可以更加明确是哪一种类型,筛选的…

在SQLServer数据库中,如果查询数据库中是否存在指定名称的索引或者外键约束等,经常会用到object_id('name','type')方法,做笔记如下: ? 语法:object_id('objectname')或object('objectname','type') 作用:该函数会返回指定对象的ID值,可以在sysobjects表中进行验证. 其中objectname数据类型为 char 或 nchar.如果 object 的数据类型是 char,那么隐性将其转换成 nchar. typ…
