Answer 1

您的语法已关闭：

CREATE OR REPLACE PROCEDURE spInsertSale2(
  SALES_ID in number,PRODUCT in varchar2,UNITCOST in decimal,QUANTITY in number)
AS
BEGIN
    if to_char(sysdate,'mm') = '01' then
        INSERT INTO Studenta_1004195.SALES 
        VALUES(SALES_ID,PRODUCT,UNITCOST,QUANTITY);
    end if;
END spInsertSale2;
/

Answer 2

乍一看，您似乎缺少“选择”一词

AS BEGIN
if
this is where you are missing the word select
to_char(sysdate, 'mm') = '01'
etc
