而现在用sql server 2008里的新技术,表变量参数解决了这个问题,先把表值函数的结果放进一个表变量里,然后在游标循环的时候就可以直间使用表变量了,而不用再
查询一次表值函数. 在没有使用表变量为参数时,运行时间为1分34秒,在使用后降为10秒.性能的提升是非常明显的!
注意,在使用表变量参数前,要先定义一个用户自定义数据类型的表结构
CREATE TYPE [dbo].[MCS_ModelList] AS TABLE(
[model] [varchar](20) NULL,
[prime] [varchar](20) NULL,
[item_id] [varchar](20) NULL,
[item_nr] [varchar](20) NULL,
[item_desc] [varchar](80) NULL,
[family] [varchar](20) NULL,
[class] [varchar](10) NULL,
[component_quantity] [tinyint] NULL,
[component_yield_factor] [tinyint] NULL,
[component_sequence_id] [int] NULL
)在存储过程里面定义这个数据类型的变量(这里MCS_ModelList 就是定义的类型名称)
declare @ModelList MCS_ModelList 然后就可以像普通表一样操作它 select * from @ModelList update @ModelList ......
