sql2008 中TSQL 增强

-- 增加了调试功能  有错误提示  
select * from codedm   -- 不存在这个表 有波浪线.

-- 指定默认值
declare @myname varchar(20)='yangze'
select @myname

-- 跟VS一样有自己提示功能
select master.dbo.spt_fallback_db.name from dbo.spt_fallback_db

-- 高级运算符
declare @n int =8
set @n+= @n
select @n

-- 一次插入多行
use Sql2008Test
insert into T values(1,'jack'),(2,'yangze')
select * from T

这样开发方便了很多呀 ！
