IN()子句oracle PLSQL中的数组

Question

我将String数组(plcListchar)传递给Stored Procedure,我想在IN()子句中使用这个String数组.

我不能直接在IN()子句中使用plcListchar.让我展示一下我是如何在JAVA中创建plcListchar字符串数组的.

 String array[] = {"o", "l"}; 
 ArrayDescriptor des = ArrayDescriptor.createDescriptor("CHAR_ARRAY", con);
 ARRAY array_to_pass = new ARRAY(des,con,array);            
 callStmtProductSearch.setArray(4, array_to_pass);

用于装箱CHAR_ARRAY,

create or replace type CHAR_ARRAY as table of varchar2;

我想在IN子句中使用plcListchar.以下是我的存储过程.

CREATE OR REPLACE PROCEDURE product_search(
            status IN varchar2, 
            plcList IN varchar2,
            i_culture_id IN number,
            plcListchar IN CHAR_ARRAY,
            status_name OUT  varchar2, 
            culture_code  OUT varchar2)
AS  
    CURSOR search_cursor IS
    SELECT p.status_name, p.culture_code
                FROM PRISM_ITEM_cultures@prism p
                WHERE p.publishable_flag=1 
                AND p.isroll =0 
                AND status = '-1'
                AND p.plc_status IN (   );
 BEGIN
           OPEN search_cursor;
           FETCH search_cursor INTO status_name, culture_code ;
           CLOSE search_cursor;
 END;

你能否建议我如何使用,如果你想提出任何其他逻辑,那就太好了.

假设您的集合是在SQL中定义的,而不仅仅是在PL/SQL中定义,您可以使用TABLE运算符(您发布的定义在语法上无效 - 您需要为其指定长度VARCHAR2)

AND p.plc_status IN (SELECT column_value
                       FROM TABLE( plcListchar ))

由于我没有您的表,因此使用该SCOTT模式的示例

SQL> create type ename_tbl is table of varchar2(30);
  2  /

Type created.

SQL> ed
Wrote file afiedt.buf

  1  declare
  2    l_enames ename_tbl := ename_tbl( 'KING', 'SMITH' );
  3  begin
  4    for i in (select *
  5                from emp
  6               where ename in (select column_value
  7                                 from table( l_enames )))
  8    loop
  9      dbms_output.put_line( 'ENAME = ' || i.ename );
 10    end loop;
 11* end;
SQL> /
ENAME = KING
ENAME = SMITH
