ORA-06550、PLS-00103、ORA-06512 函数

Question

我不知道该怎么办。我写了一个函数，编译它没有错误，但是当我运行我得到的代码时：

ORA-0650: line 3, column 14:

PLS-00103: Encountered the symbol "/" when expecting one of the following:

:= . ( @ % ; not null range default character

ORA-06512: at line 58

Vendor code 6550

这是函数：

create or replace 
FUNCTION "GET_MUSICIAN_FUN" 
( 
i_mus_id IN musicians.id%type
)
RETURN musicians%ROWTYPE
AS
o_mus_rec musicians%ROWTYPE;
BEGIN
  SELECT m.id, m.first_name, m.last_name, m.born, m.died , m.picture_path, m.bio
  INTO o_mus_rec
  FROM musicians m
  WHERE id = i_mus_id;
  RETURN o_mus_rec;
EXCEPTION
  WHEN NO_DATA_FOUND THEN
    RAISE_APPLICATION_ERROR(-20005, 'Found nothing.');
  WHEN TOO_MANY_ROWS THEN
    RAISE_APPLICATION_ERROR(-20006, 'Found too many.');
  WHEN OTHERS THEN
    RAISE_APPLICATION_ERROR(-20007, 'Cannot get musician.');
END GET_MUSICIAN_FUN;

编辑：

当我调用它时：

declare 
result musicians%rowtype;
begin
result := get_musician_fun(53); 
end;
/

我明白了："anonymous block completed"

但是当从 PHP 调用它时：

$con = oci_connect("yoni", "yoni", "//localhost/xe");
$s = oci_parse($con, "begin :rc := GET_MUSICIAN_FUN(53); end;");
$rc = oci_new_cursor($con);
oci_bind_by_name($s, ":rc", $rc, -1, OCI_B_CURSOR);
oci_execute($s); // line 41
oci_execute($rc, OCI_DEFAULT);
oci_fetch_all($rc, $res, null, -1, OCI_FETCHSTATEMENT_BY_ROW); // line 43
return $res;

我明白了：

Warning
:  oci_execute(): ORA-06550: line 1, column 14:
PLS-00382: expression is of wrong type
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored in... on line 41 

Warning
:  oci_fetch_all(): ORA-24338: statement handle not executed in... on line 43

我不是 php 专家，但您尝试将 oracle 行对象提取到 php 中。 rowtype 仅在 oracle pl/sql 代码中使用。

试试这个方法

create or replace function get_musician_fun( i_mus_id in musicians.id%type)
return varchar2
as
    musician_row varchar2(32000);
begin
  select m.id||','|| m.first_name||','|| m.last_name||','|| m.born||','|| m.died ||','|| m.picture_path||','|| m.bio
  into o_mus_rec
  from musicians m
  where id = i_mus_id;
  return musician_row;
exception
  when no_data_found then
    raise_application_error(-20005,'found nothing.');
  when too_many_rows then
    raise_application_error(-20006,'found too many.');
  when others then
    raise_application_error(-20007,'cannot get musician.');
end get_musician_fun;

并像 csv 一样在您的 php 上拆分结果。

• 查看修改后的raise_application_error 位上面的代码。
• 您可能会更好地查询数据库并获取行 没有存储过程。
