PPAS上以自定义类型数组为入参的函数及调用加java调用

--1

--创建表

CREATE TABLE TABLE_TEST

(

ID NUMBER(10,0) NOT NULL,

NAME VARCHAR2 NOT NULL,

ATTRIBUTE1 VARCHAR2,

ATTRIBUTE2 VARCHAR2,

CONSTRAINT PK_TABLE_TEST PRIMARY KEY (ID)

);

--2. 创建序列 s_TABLE_TEST.

create sequence s_TABLE_TEST start 1;

--3

--创建类型

create or replace type T_TYPE is object (

NAME VARCHAR2(100),

ATTRIBUTE1 VARCHAR2(100),

ATTRIBUTE2 VARCHAR2(100)

);

--4

--因为不支持组合类型做为出、入参数，改为如下：

create or replace procedure POPULATE_TABLE_TEST (example T_TYPE[]) as

type t_tb_seq is table of number;

l_t_seq t_tb_seq := t_tb_seq();

begin

for i in array_lower(example,1) .. array_upper(example,1) loop

l_t_seq.extend;

select s_TABLE_TEST.nextval into l_t_seq(i) from dual;

end loop;

for i in array_lower(example,1) .. array_upper(example,1) loop

insert into TABLE_TEST(id,name,attribute1,attribute2)

values (

l_t_seq(i),

example[i].NAME,

example[i].ATTRIBUTE1,

example[i].ATTRIBUTE2

);

end loop;

end;

--5

--因为不支持结构，创建T_TYPE类并覆盖其toString()方法

class T_Type {

private String name, attribute1, attribute2;

T_Type(String name, String attribute1, String attribute2) {

this.name = name;

this.attribute1 = attribute1;

this.attribute2 = attribute2;

}

@Override

public String toString() {

return "(\"" + name +"\","

+ " \"" + attribute1 + "\","

+ " \"" + attribute2 + "\")";

}

}

--6

--调用存储过程

T_Type[] values = new T_Type[]{new T_Type("obj1_name","obj1_att1", "obj1_att2"),

new T_Type("obj2_name","obj2_att1", "obj2_att2"),

new T_Type("obj3_name","obj3_att1", "obj3_att2")};

CallableStatement cstmt = con.prepareCall("{call POPULATE_TABLE_TEST(?)}");

Array array = con.createArrayOf("t_type", values);

cstmt.setArray(1, array);

cstmt.execute();

--注意

--为了使用方法con.createArrayOf，应该使用JDK1.6+和edb-jdbc16.jar，因为createArrayOf是JDBC4的功能。
