【中文标题】ORA-00947: 将值放入过程中的类型时没有足够的值【英文标题】:ORA-00947 : Not Enough Values while putting values into a type inside a procedure 【发布时间】:2015-06-14 05:18:09 【问题描述】:我创建了一些 Oracle 类型:
create or replace TYPE "RESULTS_ADMIN" AS OBJECT
(
ROWNUMBER NUMBER,
ASSET_ID VARCHAR2(1000 CHAR),
BOOK_ID VARCHAR2(10 CHAR),
asset_name VARCHAR2(50 CHAR) ,
book_author VARCHAR2(30 CHAR) ,
asset_location VARCHAR2(30 CHAR),
asset_cat VARCHAR2(50 CHAR),
asset_type VARCHAR2(10 CHAR),
publisher_name VARCHAR2(50 CHAR),
books_available NUMBER
);
create or replace TYPE "RESULT_ADMIN_TEMP" is table of LMS.results_admin;
这是一个使用它们的过程:
create or replace PROCEDURE "RETRIEVE_ASSET_ADMIN" (
aid IN asset_details.asset_id%TYPE,
aname IN asset_details.asset_name%TYPE,
acat IN asset_details.asset_cat%type,
atypeid IN asset_details.asset_type_id%type,
bauthor IN asset_details.book_author%type,
aloc IN asset_details.asset_location%type,
pub IN asset_publisher.publisher_name%type,
pagenumber IN number,
asset_cur OUT SYS_REFCURSOR )
is
v_fpgnbr number;
v_pgsize number;
v_frec number;
v_lrec number;
v_totrows number;
result_admin_temp_table result_admin_temp;
begin
v_fpgnbr := pagenumber;
v_pgsize :=10;
v_frec := (v_fpgnbr - 1 ) * v_pgsize;
v_lrec := ( v_fpgnbr * v_pgsize + 1 );
select row_number() over (order by a.asset_id) as rownum,
a.asset_id,
a.book_id,
asset_name ,
book_author ,
asset_location,
asset_cat ,
l.asset_type,
p.publisher_name,
c.books_available
bulk collect into result_admin_temp_table
from asset_details a join asset_count c
on a.book_id=c.book_id
join asset_lookup_details l
on a.asset_type_id=l.asset_type_id
join asset_publisher p
on a.book_id = p.book_id
where (aid is NULL or a.asset_id = aid ) and
(aname is NULL or asset_name like '%'||aname||'%') and
(bauthor is NULL or book_author like '%'||bauthor||'%') and
(aloc like '%SELECT%' or asset_location like '%'|| aloc ||'%') and
(acat like '%SELECT%' or asset_cat like '%'||acat||'%') and
(atypeid = 0 or a.asset_type_id = atypeid) and
(pub is NULL or p.publisher_name like '%'||pub||'%');
open asset_cur for
select
asset_id,
book_id,
asset_name ,
book_author ,
asset_location,
asset_cat ,
asset_type,
publisher_name,
books_available
from table(result_admin_temp_table)
where
rownum > v_frec and rownum < v_lrec
order by rownum asc;
end RETRIEVE_ASSET_ADMIN;
在编译代码时,我收到了ORA-00947: Not enough values error at the "bulkcollect into result_admin_temp_table" point
。我已经尝试了很多在互联网上搜索以找到解决此问题的方法。
你能告诉我哪里出错了吗?
【问题讨论】:
【参考方案1】:这就是您收到该消息的原因:您正在选择嵌套表。 Oracle 不会为您将结果集转换为类型:您需要自己做。
select RESULTS_ADMIN(
row_number() over (order by a.asset_id),
a.asset_id,
a.book_id,
asset_name ,
book_author ,
asset_location,
asset_cat ,
l.asset_type,
p.publisher_name,
c.books_available )
bulk collect into result_admin_temp_table
from asset_details a join asset_count c
on a.book_id=c.book_id
join asset_lookup_details l
on a.asset_type_id=l.asset_type_id
join asset_publisher p
on a.book_id = p.book_id)
一些额外的观察:
-
不要使用
rownum
作为别名。 ROWNUM 是 an Oracle keyword,因此您的查询不会像您想象的那样工作。
您正在使用整个结果集填充嵌套表。集合位于会话内存中。如果查询返回许多结果 - 并且考虑到参数的模糊性,我猜有时它会返回 - 集合可能会变得太大并超过 PGA 限制。
在数据库中运行分页查询是个坏主意。没有人愿意将业务逻辑放入数据库中,但每个人都希望将表示逻辑放在那里。 摇头
最后,您可以通过简单的内联查询来避免集合的开销:
open asset_cur for
select
asset_id,
book_id,
asset_name ,
book_author ,
asset_location,
asset_cat ,
asset_type,
publisher_name,
books_available
from ( select row_number() over (order by a.asset_id) as rn,
a.asset_id,
a.book_id,
asset_name ,
book_author ,
asset_location,
asset_cat ,
l.asset_type,
p.publisher_name,
c.books_available
bulk collect into result_admin_temp_table
from asset_details a join asset_count c
on a.book_id=c.book_id
join asset_lookup_details l
on a.asset_type_id=l.asset_type_id
join asset_publisher p
on a.book_id = p.book_id
where (aid is NULL or a.asset_id = aid ) and
(aname is NULL or asset_name like '%'||aname||'%') and
(bauthor is NULL or book_author like '%'||bauthor||'%') and
(aloc like '%SELECT%' or asset_location like '%'|| aloc ||'%') and
(acat like '%SELECT%' or asset_cat like '%'||acat||'%') and
(atypeid = 0 or a.asset_type_id = atypeid) and
(pub is NULL or p.publisher_name like '%'||pub||'%')
) t
where t.rn > v_frec and t.rn < v_lrec
order by t.rn asc;

以上是关于ORA-00947: 将值放入过程中的类型时没有足够的值的主要内容,如果未能解决你的问题,请参考以下文章
oracle创建存储过程时,提示错误是:错误(5,18): PL/SQL: ORA-00947: 没有足够的值?代码如下:
Oracle 选择变量,错误 ORA-00947 没有足够的值
ORA-00947 当 UPDATE 返回 BULK COLLECT INTO 用户创建的 TYPE TABLE 时出现“没有足够的值”
