PlSql %type

%type变量:用户事先并不清楚检索的数据列的数据类型,则可以使用%type定义变量

declare

name student.sname %type;

no student.sno %type;

begin

select sno,sname into no,name from  student where sno="soo1"

dbms_output.putline(name || '' ||no);

end;

 

 

%rowtype

delare 

id student%rowtype;

begin

select  * into id from student where sn0 ="s001";

dbms_output.put_line(id.name ||''||id.sage)

end;
