PL\SQL基础(三)

PL/SQL中sql语句
declare
tmpname emp.ename%type;
tmpsal  emp.sal%type;
begin
select ename,sal into tmpname,tmpsal from emp where empno=8321;
dbms_output.put_line(tmpname||' '||tmpsal);
end;
或者使用rowtype简化
declare
tmpemp emp%rowtype;
begin
select *  into tmpemp from emp where empno=8321;
dbms_output.put_line(tmpemp.ename);
end;
inset,update之类一样
declare
tmpno dept.no%rowtype :=40;
tmpname dept.name%type :='tom';
tmploc dept.loc%type :='nj';
begin
insert into dept1 values(tmpno,tmpname,tmploc);
commit;
end;
