java怎样将一组对象传入Oracle存储过程
java怎样将一组对象传入Oracle存储过程。须要注意的是jar包是有要求的,假设使用不当会导致仅仅有数字能传过去,字符串传只是去。
假设是Oracle11g则须要选用例如以下的jar包,F:\app\Administrator\product\11.2.0\dbhome_1\jlib\orai18n.jar、D:\program\weblogic\oracle_common\modules\oracle.jdbc_11.2.0\ojdbc6.jar
1:存储过程
1 CREATE OR REPLACE TYPE TEST_OBJECT AS OBJECT 2 ( 3 id number, 4 name varchar2(32) 5 ); 6 CREATE OR REPLACE TYPE TABLES_ARRAY AS VARRAY(100) OF TEST_OBJECT; 7 drop table test purge; 8 create table test 9 ( 10 id number, 11 name varchar2(32) 12 ); 13 create or replace procedure t_list_to_p(arr_t in tables_array) 14 is 15 begin 16 for i in 1..arr_t.count loop 17 insert into test values(arr_t(i).id,arr_t(i).name); 18 end loop; 19 commit; 20 end t_list_to_p;
2:Java 实现逻辑代码
1 import java.sql.CallableStatement; 2 import java.sql.Connection; 3 import java.sql.DriverManager; 4 import java.sql.SQLException; 5 import java.util.ArrayList; 6 import java.util.List; 7 import oracle.sql.ARRAY; 8 import oracle.sql.ArrayDescriptor; 9 import oracle.sql.STRUCT; 10 import oracle.sql.StructDescriptor; 11 12 public class TestListToProcedure { 13 static final String driver_class = "oracle.jdbc.driver.OracleDriver"; 14 static final String connectionURL = "jdbc:oracle:thin:@10.150.15.150:1521:orcl"; 15 static final String userID = "test"; 16 static final String userPassword = "test"; 17 public void runTest() { 18 Connection con = null; 19 CallableStatement stmt = null ; 20 try { 21 Class.forName (driver_class).newInstance(); 22 con = DriverManager.getConnection(connectionURL, userID, userPassword); 23 StructDescriptor tDescriptor = StructDescriptor.createDescriptor("TEST_OBJECT", con); 24 List<STRUCT> structs = new ArrayList<STRUCT>(); 25 Object[] tObject = null ; 26 //能够将系统中VO,DTO转化成Object对象,先创建struts 27 for(int i = 0; i<10; i++){ 28 tObject = new Object[2]; 29 tObject[0] = i; 30 tObject[1] = "name"+i; 31 STRUCT tStruct = new STRUCT(tDescriptor, con, tObject); 32 structs.add(tStruct); 33 } 34 ArrayDescriptor arrayDescriptor = ArrayDescriptor.createDescriptor("TABLES_ARRAY", con); 35 ARRAY tArray = new ARRAY(arrayDescriptor, con, structs.toArray()); 36 stmt = con.prepareCall("{call t_list_to_p(? 37 )}"); 38 stmt.setArray(1, tArray); 39 stmt.execute(); 40 } catch (SQLException e) { 41 e.printStackTrace(); 42 } catch (Exception e) { 43 e.printStackTrace(); 44 }finally{ 45 if(stmt != null){ 46 try { 47 stmt.close(); 48 } catch (SQLException e) { 49 e.printStackTrace(); 50 } 51 } 52 if(con != null){ 53 try { 54 con.close(); 55 } catch (SQLException e) { 56 e.printStackTrace(); 57 } 58 } 59 } 60 } 61 public static void main(String[] args) { 62 TestListToProcedure testListToProcedure = new TestListToProcedure(); 63 testListToProcedure.runTest(); 64 } 65 66 } 67 68
