oracle和SQL SERVER的多字段赋值简析
[sql]
create table tablea(id int,ip varchar(15),apps varchar(10))
insert into tablea select 23,'127.0.0.1','aaa'
go www.2cto.com
declare @Variable1 varchar(15),@Variable2 varchar(10)
select @Variable1 = ip ,@Variable2 = apps from tablea where id = 23
select @Variable1,@Variable2
/*
--------------- ----------
127.0.0.1 aaa
(1 行受影响)
*/
go
drop table tablea
SQLSERVER的多字值赋值方式如上所示，直接SELECT就可以
但在ORACLE的PLSQL下 select into 只能赋值单个变量，不能进行多变量同时赋值。
如 : select count(*) into nb_count from t_khz where fzbh=V_fzbh;
多变量赋值一般采取游标FETCH的方式：
[sql]
cursor c_rw is
select * from t_kh
www.2cto.com
r_rw c_rw%rowtype;
open c_rw;
loop
fetch c_rw into r_rw;
exit when c_rw%notfound;
dbms_output.put_line(r_rw.khbh||' '||r_rw.khxm||' '||r_rw.yzbm);
end loop;
close c_rw;
还有就一种方式就是用ROWTYPE
[sql]
-- Local variables here
i integer;
v_kh t_kh%rowtype;
gin
-- Test statements here
www.2cto.com
select * into v_kh from t_kh where rownum=1;
dbms_output.put_line(v_kh.khbh||' '||v_kh.khxm||' '||v_kh.yzbm);
d;
