Oracle存储过程java 调用

1、nest表组合成结果集，然后以游标变量的形式返回

--创建类型

create or replace package mytest is

  -- Author  : ADMINISTRATOR
  -- Created : 2008-5-13 11:19:28
  -- Purpose : test
 
TYPE record_type IS RECORD(
      code   VARCHAR2(18),
      p_name VARCHAR2(16));

TYPE ref_cur_type IS REF CURSOR;
end mytest;

CREATE OR REPLACE TYPE table_type IS TABLE OF record_type;

--创建过程

CREATE OR REPLACE PROCEDURE testproc( v_ref_cur out mytest.ref_cur_type) IS

   v_record record_type;

   v_table table_type := table_type();

BEGIN
   FOR i IN 1 .. 9 LOOP
      v_record := NEW record_type('45212319830810435' || i, '侯廷文' || i);
      v_table.EXTEND;
      v_table(i) := v_record;
   END LOOP;

   OPEN v_ref_cur FOR
      SELECT * FROM TABLE(CAST(v_table AS table_type));

END testproc;

--java代码：

OracleCallableStatement cstmt = (OracleCallableStatement) con
                .prepareCall(&{call testproc(?)}&);
        cstmt.registerOutParameter(1, OracleTypes.CURSOR);
        cstmt.execute();
        ResultSet rs = (ResultSet) cstmt.getObject(1);
        while (rs.next()) ...{
            System.out.print(rs.getString(1) + & &);
            System.out.print(rs.getString(2) + & &);
            System.out.println();
        }

2、PL/SQL varray数组类型的形式返回结果

--创建类型
CREATE OR REPLACE TYPE myarr IS VARRAY(200) OF VARCHAR2(256);

--创建过程

CREATE OR REPLACE PROCEDURE testvarray(thearr OUT myarr) IS

BEGIN
   thearr := myarr();
   FOR i IN 1 .. 100 LOOP
      thearr.EXTEND;
      thearr(i) := '我是侯廷文'||i;
   END LOOP;
END testvarray;

--java代码：

OracleCallableStatement cstmt = (OracleCallableStatement) con.prepareCall(&{call testvarray(?)}&);
        cstmt.registerOutParameter(1, OracleTypes.ARRAY, &MYARR&);

　　  cstmt.execute();
        ARRAY array = cstmt.getARRAY(1);
        Datum[] datas = array.getOracleArray();

        for (int i = 0; i < datas.length; i++) ...{
            System.out.println(i + &:& + new String(datas[i].getBytes()));
        }

3、PL/SQL 的Object类型返回，对应jdbc的Struct

--创建类型

CREATE OR REPLACE TYPE record_type as object(code VARCHAR2(18),
                                             p_name VARCHAR2(16));

--创建过程

create or replace procedure testStruct(theObj OUT record_type) is
begin
  theObj:=record_type('452134198308104351','侯廷文');
end testStruct;

--java代码：

 OracleCallableStatement cstmt = (OracleCallableStatement) con
                .prepareCall(&{call testStruct(?)}&);
        cstmt.registerOutParameter(1, OracleTypes.STRUCT, &RECORD_TYPE&);
        cstmt.execute();
        STRUCT struct = cstmt.getSTRUCT(1);
        Datum[] datas = struct.getOracleAttributes();
      for (int i = 0; i < datas.length; i++) ...{
            System.out.print(i + &:& + new String(datas[i].shareBytes()));
            System.out.println();
        }

4、PL/SQL 的table类型返回，对应jdbc的ARRAY

--创建类型

create or replace type nest_table_type IS TABLE OF VARCHAR2(200);

--创建过程

CREATE OR REPLACE PROCEDURE testtable(thetable OUT nest_table_type) IS
BEGIN
   thetable := nest_table_type();
   FOR i IN 1 .. 100 LOOP
      thetable.EXTEND;
      thetable(i) := dbms_random.STRING('X', 3) || '侯廷文' || i;
   END LOOP;
END testtable;

--java代码：

 OracleCallableStatement cstmt = (OracleCallableStatement) con
         .prepareCall(&{call testtable(?)}&);
         cstmt.registerOutParameter(1, OracleTypes.ARRAY, &NEST_TABLE_TYPE&);
         cstmt.execute();
         ARRAY array = cstmt.getARRAY(1);
         Datum[] datas=array.getOracleArray();
         for (int i = 0; i < datas.length; i++) ...{
         System.out.print(i + &:& + new String(datas[i].shareBytes()));
         System.out.println();
         }
 

5、PL/SQL 的Index table类型,注意该类型只能在
   oci8方式连接下使用,所需要的动态连接库文件（ocijdbc9.dll）要在环境变量里进行设置
   （例如：path=D:oracleora90BIN），在不同的环境下OCI驱动还可能出现类装载异常，
   所以返回索引表尽管方便，但偶尔会出现意想不到的错误

--创建类型

CREATE OR REPLACE PACKAGE p_type IS
TYPE index_table_type IS TABLE OF VARCHAR2(256) INDEX BY BINARY_INTEGER;
END;

--创建过程

create or replace procedure testIndexTable(v_iTable OUT p_type.index_table_type) is
begin
  FOR i IN 1 .. 100 LOOP
  v_iTable(i):=dbms_random.string('X',5)||'侯廷文'||i;END LOOP;
end testIndexTable;

--java代码：

 OracleCallableStatement cstmt = (OracleCallableStatement) con
                .prepareCall(&{call testindextable(?)}&);
        cstmt.registerIndexTableOutParameter(1, 200, OracleTypes.VARCHAR, 256);
        cstmt.execute();
        String[] strs = (String[]) cstmt.getPlsqlIndexTable(1);
        for (int i = 0; i < strs.length; i++) ...{
            System.out.println(i + &:& + strs[i]);
        }

6、nestTable里装的是Person Object

--创建类型

CREATE OR REPLACE TYPE Person AS OBJECT
(
       p_code VARCHAR2(32),
       p_name VARCHAR2(16),
       p_age NUMBER,
       p_birthday DATE
);

CREATE OR REPLACE TYPE person_table_type IS TABLE OF Person;

--创建过程

CREATE OR REPLACE PROCEDURE testtableofobject(v_table OUT person_table_type) IS
BEGIN
   v_table := person_table_type();
   FOR i IN 1 .. 5 LOOP
      v_table.EXTEND;
      v_table(i) := NEW person('45212319880810435' || i,
                               '侯廷文' || i,
                               20 + i,
                               to_date('1985-08-1' || i, 'YYYY-MM-DD'));
   END LOOP;
END testtableofobject;

--java代码：

OracleCallableStatement cstmt = (OracleCallableStatement) con
                .prepareCall(&{call testtableofobject(?)}&);
       cstmt.registerOutParameter(1, OracleTypes.ARRAY, &person_table_type&
                .toUpperCase());
        cstmt.execute();
        ARRAY array = cstmt.getARRAY(1);
        Datum[] datas = array.getOracleArray();
        for (int i = 0; i < datas.length; i++) ...{
            System.out.print(i + &: &);
            Datum[] personAttributes = ((STRUCT) datas[i])
                    .getOracleAttributes();
            System.out.print(&p_code:&
                    + new String(personAttributes[0].getBytes()) + & &);
            System.out.print(&p_name:&
                    + new String(personAttributes[1].getBytes()) + & &);
            System.out.print(&p_age:& + personAttributes[2].intValue() + & &);
            System.out.print(&p_birthday:& + personAttributes[3].dateValue()
                    + & &);
            System.out.println();
        }

7、输入参数为nestTable里装的是Person Object
   注意要将nls_charset12.jar放入ClassPath中，否则报SQLException:
   Non supported character set: oracle-character-set-852

--创建类型

CREATE OR REPLACE TYPE Person AS OBJECT
(
       p_code VARCHAR2(32),
       p_name VARCHAR2(16),
       p_age NUMBER,p_birthday DATE
);

CREATE OR REPLACE TYPE person_table_type IS TABLE OF Person;

CREATE TABLE personTable OF person;

--创建过程

CREATE OR REPLACE PROCEDURE testInPersons(persons IN person_table_type) IS
BEGIN
FORALL i IN persons.first .. persons.count
INSERT INTO personTable VALUES(persons(i));
COMMIT;
END testInPersons;

--java代码：

OracleCallableStatement cstmt = (OracleCallableStatement) con
                .prepareCall(&{call testInPersons(?)}&);
        StructDescriptor sd = new StructDescriptor(&PERSON&, con);
        Object[] personAttrs1 = new Object[] ...{ &This is code11&, &侯廷文11&,
                new NUMBER(32), new Date(new java.util.Date().getTime()) };
        STRUCT person1 = new STRUCT(sd, con, personAttrs1);

        Object[] personAttrs2 = new Object[] ...{ &This is code22&, &侯廷文22&,
                new NUMBER(33), new Date(new java.util.Date().getTime()) };
        STRUCT person2 = new STRUCT(sd, con, personAttrs2);

        ArrayDescriptor ad = new ArrayDescriptor(&person_table_type&
                .toUpperCase(), con);
        ARRAY persons = new ARRAY(ad, con, new STRUCT[] ...{ person1, person2 });
        cstmt.setARRAY(1, persons);
        cstmt.execute();
    }
