Question

我一直在尝试为我的表编译此触发器，并且我继续收到此错误：

错误消息 ：

 Compilation failed, line 4 (19:39:58) The line numbers associated with
 compilation errors are relative to the first BEGIN statement. This
 only affects the compilation of database triggers. PL/SQL: ORA-00923:
 FROM keyword not found where expected

 Compilation failed, line 4
 (19:39:58) The line numbers associated with compilation errors are
 relative to the first BEGIN statement. This only affects the
 compilation of database triggers. PL/SQL: SQL Statement ignored

这是我的 触发器 ：

Create or Replace Trigger NEWSALARY 
  before insert or update on CREW
  for each row
Declare 
  v_emphours AIRPLANE. EMPWORKINGHOURS%TYPE;
Begin
  select EMPWORKINGHOURS into v_ emphours 
    from "AIRPLANE" 
   where  AIRPLANEID =:NEW."AirPlaneID";
  if v_emphours > 8 then 
   :NEW."Salary":= :NEW."Salary"* 50;
  end if;
End;

Answer 1

声明部分有一个空格（下面是灰色的一个字符长度区域）

v_emphours AIRPLANE。 EMPWORKINGHOURS％TYPE;

在这里

v _ emphours

删除这些空格并删除无用的引用，您可以运行此语句而不会出现错误：

create or replace TRIGGER  NEWSALARY 
before insert or update on CREW
for each row
Declare 
v_emphours AIRPLANE.EMPWORKINGHOURS%TYPE;
BEGIN
select EMPWORKINGHOURS into v_emphours from AIRPLANE Where  AIRPLANEID =:NEW.AirPlaneID;
if 
v_emphours > 8
then 
:NEW.Salary:= :NEW.Salary* 50;
END IF;
End;
