jdbc从存储过程返回单个对象或PL/SQL表

返回单个PL/SQL表，元素为标量类型
创建类型，包头，包体
create or replace type tab_array is table of varchar2(38);
/

create or replace package addnum
is
procedure abc(e_name in tab_array,t_name out tab_array);
end;
/

create or replace package body addnum is
procedure abc
(e_name in tab_array,t_name out tab_array)
is
begin
for i in 1..e_name.count loop
insert into t(name) values(e_name(i));
end loop;

select name bulk collect into t_name from t;
end;
end;
/

JDBC操作
package com.lovo;

import java.sql.Connection;
import java.sql.DriverManager;

import oracle.jdbc.OracleCallableStatement;
import oracle.jdbc.OracleTypes;
import oracle.sql.ARRAY;
import oracle.sql.ArrayDescriptor;
import oracle.sql.Datum;

public class JDBCMain {
public static void main(String[] args) throws Exception {
new oracle.jdbc.driver.OracleDriver();

Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@192.168.0.99:1521:HXM", "me", "123");
String[] strs = new String[]{"abc","cba"};
OracleCallableStatement call = (OracleCallableStatement) conn.prepareCall("{call addnum.abc(?,?)}");
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor("TAB_ARRAY", conn); /*TAB_ARRAY是类型名，必须大写*/
call.setArray(1, new ARRAY(descriptor,conn,strs));
call.registerOutParameter(2, OracleTypes.ARRAY,"TAB_ARRAY");
call.execute();
ARRAY arr = call.getARRAY(2);
Datum[] dat = arr.getOracleArray();
for(int i=0;i<dat.length;i++){
System.out.println(dat[i]);
}

conn.close();
}
}

返回单个对象
建立对象类型
create or replace type t_obj as object
(id int,
name varchar2(20)
);

建立对象表
create table t of t_obj;

insert into t values(t_obj(1,'abc1'));
insert into t values(t_obj(2,'abc2'));
insert into t values(t_obj(3,'abc3'));
insert into t values(t_obj(4,'abc4'));
insert into t values(t_obj(5,'abc5'));

建立包头和包体
create or replace package addnum
is
procedure abc(e_name in int,t_per out t_obj);
end;
/

create or replace package body addnum is
procedure abc
(e_name in int,t_per out t_obj)
is
begin
select value(p) into t_per from t p where p.id=e_name;
end;
end;
/

jdbc操作
TypeDescriptor td = TypeDescriptor.getTypeDescriptor("T_OBJ", (OracleConnection) conn);
OracleCallableStatement call = (OracleCallableStatement) conn.prepareCall("{call addnum.abc(?,?)}");
call.setInt(1, 3);
call.registerOutParameter(2, OracleTypes.STRUCT, "T_OBJ");
call.execute();

STRUCT str = call.getSTRUCT(2);

Object[] objs = str.getAttributes();
for(int i=0;i<objs.length;i++){
System.out.println(str.getDescriptor().getMetaData().getColumnName(i+1) + "," + objs[i]);
}

返回1个表，元素是对象
建立对象类型，表类型，包头，包体
create or replace type t_obj as object
(id int,
name varchar2(20)
);
/
create or replace type t_table is table of t_obj;
/

create or replace package addnum
is
procedure abc(e_name in int,t_per out t_table);
end;
/

create or replace package body addnum is
procedure abc
(e_name in int,t_per out t_table)
is
begin
select value(p) bulk collect into t_per from t p;
end;
end;
/
jdbc操作
TypeDescriptor td = TypeDescriptor.getTypeDescriptor("T_TABLE", (OracleConnection) conn);
OracleCallableStatement call = (OracleCallableStatement) conn.prepareCall("{call addnum.abc(?,?)}");
call.setInt(1, 1);
call.registerOutParameter(2, OracleTypes.ARRAY,"T_TABLE");
call.execute();

ARRAY arr = call.getARRAY(2);
Datum[] dat = arr.getOracleArray();

for(int i=0;i<dat.length;i++){
STRUCT struct = (STRUCT) dat[i];

Object[] objs = struct.getAttributes();
System.out.println("id:" + objs[0] + ",name:" + objs[1]);
}
