from (select E.grade,
E.TestLevel,
(select AA * 2 BB
from (select avg(Salarys) AA
from andy_shen_salary_information S)) Avgsalary

open cr1;
for i in cr1 loop
select decode(AA,' ',i.Avgsalary),Salarys,salarymonth,Id from (select A.*, ' ' AA from andy_shen_salary_information A where Id in

pls 00428:an INTO clause is expected in this SELECT statement的错误

------解决方案--------------------单独的select语句需要跟into配合。。基本常识了
------解决方案--------------------这个查询返回是多行的记录
bulk collect
------解决方案--------------------
