程序错误ORA-06512

Question

您好我有一个oracle数据库，我正在尝试添加一个过程来根据输入选择驱动程序 但是我收到此错误消息

ORA-06502 numeric or value error
ORA-06512: at line 9

create or replace
PROCEDURE "SELECTDRIVE" 
(LicenseNumber in number, FirstNamee out VARCHAR2, LastNamee out VARCHAR2, ContactNumberr out NUMBER)
as
begin

select d.firstname, d.lastname, d.contactnumber 
into   FirstNamee , LastNamee , ContactNumberr
from   Driver d
where d.license = LicenseNumber;
end;

，这是从

中选择的表格

LICENSE         NUMBER(10,0)
FIRSTNAME       VARCHAR2(15 BYTE)
LASTNAME        VARCHAR2(15 BYTE)
PHOTO           BLOB
CONTACTNUMBER   NUMBER(11,0)

任何想法？ 感谢

Answer 1

哪一行第9行？

这段代码没有错，至少在我尝试时是这样：

SQL> create table driver (
  2    LICENSE         NUMBER(10,0),
  3    FIRSTNAME       VARCHAR2(15 BYTE),
  4    LASTNAME        VARCHAR2(15 BYTE),
  5    PHOTO           BLOB,
  6    CONTACTNUMBER   NUMBER(11,0));

Table created.

SQL> insert into driver (license, firstname, lastname, contactnumber)
  2    values (1, 'Little', 'Foot', 1234);

1 row created.

SQL> create or replace PROCEDURE SELECTDRIVE
  2    (LicenseNumber in number,
  3     FirstNamee out VARCHAR2,
  4     LastNamee out VARCHAR2,
  5     ContactNumberr out NUMBER)
  6  as
  7  begin
  8    select d.firstname, d.lastname, d.contactnumber
  9      into   FirstNamee , LastNamee , ContactNumberr
 10      from   Driver d
 11      where d.license = LicenseNumber;
 12  end;
 13  /

Procedure created.

SQL> declare
  2    l_fn driver.firstname%type;
  3    l_ln driver.lastname%type;
  4    l_cn driver.contactnumber%type;
  5  begin
  6    selectdrive(1, l_fn, l_ln, l_cn);
  7  end;
  8  /

PL/SQL procedure successfully completed.

确保输入参数LicenseNumber的值不超过（10,0）的精度。据我所知，当您调用该过程而不是在创建过程时，您会收到错误。 捕获数据库端传入参数的值。
