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();
}
