oracle - PLS-00103 : Encountered the symbol “)” when expecting one of the following:

Question

我有以下针对Oracle的存储过程:

create or replace
procedure bns_saa_message_get()  <--- PROBLEM IS HERE BC I HAVE NO PARAMS TO PASS
AS
begin
  select HostNumber, SAAMessage from BNS_SAA_MESSAGES where HostNumber=(select max(HostNumber) from BNS_SAA_MESSAGES);
end;

尝试编译时收到以下错误:

Error(2,31): PLS-00103: Encountered the symbol ")" when expecting one of the following:     <an identifier> <a double-quoted delimited-identifier>    current 

问题:
如何在不需要向其传递任何参数的地方创建存储过程？

Answer 1

卸下支架:

CREATE OR REPLACE PROCEDURE bns_saa_message_get
AS
BEGIN
   SELECT hostnumber, saamessage
     FROM bns_saa_messages
    WHERE hostnumber = (SELECT MAX (hostnumber) FROM bns_saa_messages);
END;

编辑:

要回答第二个问题...

CREATE OR REPLACE PROCEDURE bns_saa_message_get
AS
   v_hostnumber bns_saa_messages.hostnumber%TYPE;
   v_saamessage bns_saa_messages.saamessage%TYPE;
BEGIN
   SELECT hostnumber, saamessage
     INTO v_hostnumber, v_saamessage 
     FROM bns_saa_messages
    WHERE hostnumber = (SELECT MAX (hostnumber) FROM bns_saa_messages);
END;

假设您只从查询中返回一行。
如果得到的行不止一个，则必须将 bulk collect放入集合中。
