我正在使用的程序有一个以逗号分隔的input
变量。就在我现在运行测试脚本的时候,我没有得到任何价值。这是我到目前为止所拥有的。
procedure get_patient(
p_statusmnemonic_in in membermedicalreconcilationhdr.reconciliationstatusmnemonic%type,
p_return_cur_out out sys_refcursor,
p_err_code_out out number,
p_err_mesg_out out varchar2)
is
begin
open p_return_cur_out for
select h.primarymemberplanid,
h.assigneduserid,
h.accountorgid,
h.reconciliationstatusmnemonic,
h.estimatedenddt,
h.actualenddt,
h.inserteddt,
h.insertedby,
h.updateddt,
h.updatedby
from membermedicalreconcilationhdr h
where h.reconciliationstatusmnemonic in (p_statusmnemonic_in);
p_err_code_out := 0;
exception
when others then
p_err_code_out := -1;
p_err_mesg_out := 'error in get_patient=> ' || sqlerrm;
end get_patient;
以下是测试脚本:
set serveroutput on
declare
type tempcursor is ref cursor;
v_cur_result tempcursor;
errcode number;
errmesg varchar2(1000);
p_primarymemberplanid_in membermedicalreconcilationhdr.primarymemberplanid%type;
p_assigneduserid_in membermedicalreconcilationhdr.assigneduserid%type;
p_accountorgid_in membermedicalreconcilationhdr.accountorgid%type;
p_reconstatusmnemonic_in membermedicalreconcilationhdr.reconciliationstatusmnemonic%type;
p_estimatedenddt_in membermedicalreconcilationhdr.estimatedenddt%type;
p_actualenddt_in membermedicalreconcilationhdr.actualenddt%type;
p_inserteddate_in membermedicalreconcilationhdr.inserteddt%type;
p_insertedby_in membermedicalreconcilationhdr.insertedby%type;
p_updateddate_in membermedicalreconcilationhdr.updateddt%type;
p_updatedby_in membermedicalreconcilationhdr.updatedby%type;
begin
get_patient
('COMPLETE,SUSPENDED_PRIOR_TO_COMPARE',v_cur_result, errcode, errmesg);
--('COMPLETE',v_cur_result, errcode, errmesg);
loop
fetch v_cur_result into p_primarymemberplanid_in,p_assigneduserid_in,p_accountorgid_in,p_reconstatusmnemonic_in,
p_estimatedenddt_in,p_actualenddt_in,p_inserteddate_in,p_insertedby_in,
p_updateddate_in,p_updatedby_in;
dbms_output.put_line(' planid '||p_primarymemberplanid_in||' userid '||p_assigneduserid_in);
exit when v_cur_result%notfound;
end loop;
dbms_output.put_line(' error code '||errcode||' message '||errmesg);
end;
到目前为止,当我只有一个输入值时,我会得到值,但是当我尝试做两个时,我什么也得不到。我做过研究,看起来我的select
陈述是正确的,所以我不知道我做错了什么。感谢任何帮助。谢谢。

如果您可以更改程序的定义,则可以通过合适的集合获得更好的服务。
CREATE TYPE status_tbl IS TABLE OF VARCHAR2(100);
procedure get_patient(
p_statusmnemonic_in in status_tbl,
p_return_cur_out out sys_refcursor,
p_err_code_out out number,
p_err_mesg_out out varchar2)
is
begin
open p_return_cur_out for
select h.primarymemberplanid,
h.assigneduserid,
h.accountorgid,
h.reconciliationstatusmnemonic,
h.estimatedenddt,
h.actualenddt,
h.inserteddt,
h.insertedby,
h.updateddt,
h.updatedby
from membermedicalreconcilationhdr h
where h.reconciliationstatusmnemonic in (SELECT *
FROM TABLE(p_statusmnemonic_in));
...
否则,您将不得不求助于使用动态SQL(这会产生安全性和性能影响),或者您需要编写代码来将逗号分隔的字符串解析为集合,然后使用TABLE
运算符在查询中使用该集合。
假设您修改了过程的签名,则还必须更改调用,以便传入集合。
get_patient
(status_tbl('COMPLETE','SUSPENDED_PRIOR_TO_COMPARE'),
v_cur_result,
errcode,
errmesg);
只是指出它,编写具有错误代码和错误消息OUT
参数而不是抛出异常的过程通常是非常不满意的。消除这些参数并在遇到错误时抛出异常更有意义。否则,您依赖于每个过程的每个调用者来正确检查返回的状态代码和消息(您的示例代码不执行此操作)。而且你正在丢失大量有价值的信息,比如错误发生在哪一行,错误堆栈是什么等等。
由于您不发布表定义或样本数据,因此我们无法测试此代码。不过,这是一个快速演示,它将如何运作
SQL> create table patient (
2 patient_id number primary key,
3 status varchar2(10),
4 name varchar2(100)
5 );
Table created.
SQL> insert into patient values( 1, 'COMPLETE', 'Justin' );
