【SQLSerrver】游标的使用（游标循环遍历一个表中的数据）

drop table aa
go
create table aa
(
[name] nvarchar(20),
[language] nvarchar(20)
)
go

insert into aa([name],[language]) values ('张学友','zh');
insert into aa([name],[language]) values ('张学友','en');
insert into aa([name],[language]) values ('刘德华','zh');
insert into aa([name],[language]) values ('黎明','jp');
insert into aa([name],[language]) values ('刘德华','jp');
go

declare  curaa cursor
