(20分)求一个insert语句!
insert   into   tb_Ref_know2cate
(Category_id,Knowledge_id)
values( '123 ', '234 ')

234=select   Category_id   from   tb_Category   where   Category_name= 'java '

插入一个表tb_Ref_know2cate   需要取到2个值,假设分别为123,234

其中234的值是由select   Category_id   from   tb_Category   where   Category_name= 'java '   得到的.

我的问题是如何把这2个语句写在一起,或者写成一个存储过程.

------解决方案--------------------
insert into tb_Ref_know2cate
(Category_id,Knowledge_id)
select top 1 '123 ', Category_id from tb_Category where Category_name= 'java '

insert into tb_Ref_know2cate
(Category_id,Knowledge_id)
