表名 tbltest
字段(id,name,age)
我想批量插入个人的名字和年龄,这存储过程怎么写?名字和年龄之间用逗号隔开,即 name('张,王,李,赵') age('18,20,21,22')
name 和age 是传过来的变量,这个存储过程怎么写??
谢谢谢谢
create sp_name9
@name varchar(200),
@age varchar(200)
as
begin...
end
中间的咋写??谢谢谢谢

标题:分解字符串并查询相关数据
作者:爱新觉罗.毓华(十八年风雨,守得冰山雪莲花开)
时间:2008-03-18
地点:广东深圳
说明:通过使用函数等方法分解字符串查询相关数据。问题:通过分解一个带某种符号分隔的字符串在数据库中查找相关数据。
例如 @str = '1,2,3',查询下表得到记录1,4,5,6
ID TypeID
1 1,2,3,4,5,6,7,8,9,10,11,12
2 2,3
3 3,7,8,9

5 4,5
6 6,7
