如何使以下包装器选择所有列*而不是 if_type 和 number_infected ?
How do i make the following wrapper select all columns "*" instead of just if_type, and number_infected?
--spec create or replace package WrapperSample is type TResultRow is record( if_type codes.cd%type ,number_infected Integer); type TResultRowList is table of TResultRow; function GetADedIcWarningsProv ( p_hos_id in work_entity_data.hos_id%type ,p_date in date ) return TResultRowList pipelined; end WrapperSample; / --body create or replace package body WrapperSample is function GetADedIcWarningsProv ( p_hos_id in work_entity_data.hos_id%type ,p_date in date ) return TResultRowList pipelined is v_refcur eOdatatypes_package.eOrefcur; currentRow TResultRow; begin v_refcur := YourSchema.getADedIcWarningsProv(p_hos_id, p_date); loop fetch v_refcur INTO currentRow; exit when v_refcur%NotFound; pipe row(currentRow); end loop; close v_refcur; return; end; end WrapperSample; /推荐答案
请了解您的问题和要求。
I am not sure if I do understand your question and requirement.
但是,如果您正在寻找一种获取表格内容或其中一部分的方法,这可能是您如何处理:
But if you're looking for a way to get a table's content, or a portion thereof, this is probably how you would approach it:
create table tq84_test_table ( col_1 number, col_2 varchar2(10), col_3 date ); insert into tq84_test_table values (1, 'one' , sysdate); insert into tq84_test_table values (2, 'two' , sysdate+1); insert into tq84_test_table values (3, 'three', sysdate-1); create or replace package tq84_sss as type record_t is table of tq84_test_table%rowtype; function GetADedIcWarningsProv return record_t; end; / create or replace package body tq84_sss as function GetADedIcWarningsProv return record_t is ret record_t; begin select * bulk collect into ret from tq84_test_table; return ret; end GetADedIcWarningsProv; end; /然后您可以使用此功能:
You would then later use this function like so:
declare table_content tq84_sss.record_t; begin table_content := tq84_sss.GetADedIcWarningsProv; for i in 1 .. table_content.count loop dbms_output.put_line(table_content(i).col_1 || ' ' || table_content(i).col_2 || ' ' || table_content(i).col_3 ); end loop; end; /更多推荐
