需要存储包示例中的Oracle存储过程接受array(table)参数 [英] An Oracle stored procedure accept array(table) parameter in package example needed

问题描述

此问题是我的问题的一部分

This question is a part of my question how to pass javascript array to oracle store procedure by ado parameter object

我认为将其分为三个小部分可以更快地得到答案.

I think divide it to 3 small parts will get answer faster.

这个问题.

我知道我们可以声明一个表类型并使用

I know we can declare a table type and use

select last_name 
from employees in (select * from table(cast(my_table_type_var as my_table_type));

但是从创建包含程序的新程序包中我总是会出错.我读了一个线程说我需要清除一个sql(在模式中)类型，因为sql和pl/slq没有使用相同的引擎.我尝试通过spl * plus在架构中创建类型，但仍然遇到相同的错误 所以请首先为此提供一个工作包示例.

but I always get error from create new package which include a procedure has this. and I read some thread said I need to declear a sql(in schema) type because sql and pl/slq are not using same engine. I try create type in schema by spl*plus, but still get same errors so I need a working package example for this first please.

推荐答案

您需要一个SQL对象才能从SELECT调用TABLE运算符.这是一个小例子(9iR2):

You need a SQL object to call the TABLE operator from a SELECT. Here's a small example (9iR2):

SQL> CREATE TYPE table_number is TABLE OF NUMBER;
  2  /

Type created.

SQL> SELECT * FROM TABLE(table_number(1,2,3));

COLUMN_VALUE
------------
           1
           2
           3

您可以在此处改用函数(请注意，我的TYPE仍在包外部定义):

You can use a function here instead (note that my TYPE is still defined outside the package):

SQL> CREATE OR REPLACE PACKAGE pkg AS
  2     FUNCTION f RETURN table_number;
  3  END;
  4  /

Package created.

SQL> CREATE OR REPLACE PACKAGE BODY pkg AS
  2     FUNCTION f RETURN table_number IS
  3     BEGIN
  4        RETURN table_number(4,5,6);
  5     END;
  6  END;
  7  /

Package body created.

SQL> SELECT * FROM table(pkg.f);

COLUMN_VALUE
------------
           4
           5
           6
