在編寫select...into...from 的語句中,如果返回的結果集爲空，就會出現ora-1403 :no data found，解決方法如下：
exception
when NO_DATA_FOUND etc etc etc.
end;
You Asked
Tom,
We´ve just migrated from Oracle 9.0.1 to 9.2 and, coincidence or not, I´m facing
a problem I had never faced before.
The NO_DATA_FOUND exception is not being raised from my PL/SQL functions
anymore!!! If I put a exception block to handle the excpetion, it´s trapped and
all the instructions in the block are executed. But if I remove the exception
block, no exception is raised to the caller.
In procedures, this doesn´t happen.
Some examples of this strange behavior follows:
create or replace procedure proc_foo is
l_value varchar2(1);
begin
select dummy
into l_value
from dual
where dummy = '-';
DBMS_OUTPUT.Put_Line(l_value);
end;
/
Procedure created.
create or replace function func_foo return varchar2 is
l_value varchar2(1);
begin
select dummy
into l_value
from dual
where dummy = '-';
return l_value;
end;
/
Function created.
-- This one raises an error
begin
proc_foo;
end;
/
begin

-- This one does not
select func_foo from dual;
FUNC_FOO
----------------------------------------------
Is there some parameter (or anything else) that controls this?
Thanks.

no data found in a function called from sql just says "ok, no more data, please
stop"
this is true for 71, 72, 73, 80, 8ir1, 8ir2, 8ir3, 9ir1, 9ir2....
