储存过程 in invalid解决思路

储存过程 in invalid
储存过程如下
create or replace procedure IC_GETSEQUENCENUM
(
 SEQUENCENAME in varchar2(100),
 SEQNUM out number
)
as 
begin
  select SEQUENCENAME.nextval into SEQNUM from dual; 
   
end IC_GETSEQUENCENUM;


在PL/SQL里面建了，报上面的错



[解决办法]

SQL code

create or replace procedure IC_GETSEQUENCENUM(SEQUENCENAME in varchar2,--(100), --这里只需要定义变量类型，不需要定义大小                                              SEQNUM       out number) asbegin  select SEQUENCENAME.nextval into SEQNUM from dual; end IC_GETSEQUENCENUM

1,一楼说了定义变量类型，不要加()大小
2,sequence需要定义，不是拿来就可以nextval的
