java plsql 調用oracle數組類型

首先當然是在oracle中建立type

CREATE OR REPLACE TYPE cux_proxy_bid_award_rec IS OBJECT
(
  trading_partner_id NUMBER,
  bid_price          NUMBER,
  bid_publish_date   DATE,
  bid_award_flag     VARCHAR2(10)
);

再建立引用type

CREATE OR REPLACE TYPE cux_proxy_bid_award_tbl IS TABLE OF CUX_PROXY_BID_AWARD_REC;

 

java中調用

import java.util.ArrayList;
import java.sql.SQLException;

import oracle.sql.ARRAY;
import oracle.sql.ArrayDescriptor;
import oracle.sql.STRUCT;
import oracle.sql.StructDescriptor;

import oracle.jdbc.OracleCallableStatement;
import oracle.jdbc.OracleConnection;



    public void crtSuppResponseAndBidAward(String auctionHeaderId){
         java.util.ArrayList  array = new  java.util.ArrayList();
        
        PonSourceProxyBidVOImpl vo  = this.getPonSourceProxyBidVO1();
        vo.first();
        vo.previous();
        while(vo.hasNext()){
            Row row = vo.next();
            Object[] obj = new Object[4];
            obj[0] = (Number)row.getAttribute("TradingPartnerId");
            obj[1] = (Number)row.getAttribute("BidPrice");
            obj[2] = (Date)row.getAttribute("BidPublishDate");
            obj[3] = (String)row.getAttribute("BidAwardFlag")!=null?row.getAttribute("BidAwardFlag"):"N";
            //構造ArrayList
            array.add(obj);
        }
        
        OracleCallableStatement statement = null;
        OracleConnection oracleConnection = (OracleConnection)this.getOADBTransaction().getJdbcConnection();
        try{
            //將arraylist解析為STRUCT
            STRUCT[] arrayOfSTRUCT = createMyRows(oracleConnection, array);
            
            //此處使用引用的TYPE
            //不能調用在PACKAGE中定義的TYPE
            ArrayDescriptor tableOfBidDescriptor = 
                                          ArrayDescriptor.createDescriptor("CUX_PROXY_BID_AWARD_TBL", 
                                                                                      oracleConnection);
                                                                                              
            ARRAY localARRAY = new ARRAY(tableOfBidDescriptor, oracleConnection, arrayOfSTRUCT);
            
           OracleCallableStatement stmt = (OracleCallableStatement)getOADBTransaction().createCallableStatement("{ call CUX_PON_SOURCING_PUB.AUTO_CRT_BID_AWARD(:1, :2, :3, :4, :5) }", -1);
           
            String  aucHeaderIdEncrypt = SourcingServerUtil.URLEncrypt(getOADBTransaction(), auctionHeaderId );
            stmt.setString(1, aucHeaderIdEncrypt);
            stmt.setString(2, auctionHeaderId);
            stmt.setARRAY(3, localARRAY);
            stmt.registerOutParameter(4, Types.NUMERIC);
            stmt.registerOutParameter(5, Types.VARCHAR);
            stmt.execute();
            oracle.sql.NUMBER retState = stmt.getNUMBER(4);
            retState.toString();
            System.out.println("stmt.getNUMBER(4)  "+stmt.getNUMBER(4));
            LogUtil.of(" String.valueOf(stmt.getNUMBER(4))  "+String.valueOf(stmt.getNUMBER(4))+" retState "+retState.stringValue(), this).print(this);
            
            ModelUtil.commit(this, true);
            
            String retStatus = stmt.getNUMBER(4).stringValue() ;
            String retMsg = stmt.getString(5);
            
            
            if( "0".equals(retStatus)){
                OAException dialogMsg = new OAException("決標完成！", OAException.CONFIRMATION);

            }
            
        }catch(SQLException e){
            throw OAException.wrapperException(e);
        }
        
        
    }

    ////將arraylist解析為STRUCT
    private STRUCT[] createMyRows(Connection paramConnection, 
                                   java.util.ArrayList paramArrayList) {
        
        int j = paramArrayList.size();
        STRUCT[] arrayOfSTRUCT;
        try {
            //此處使用定義的原始TYPE OBJECT，或者TABLE
            StructDescriptor localStructDescriptor = 
                StructDescriptor.createDescriptor("CUX_PROXY_BID_AWARD_REC", 
                                                  paramConnection);
            int k;
            arrayOfSTRUCT = new STRUCT[j];

            for (k = 0; k < j; k++) {
                arrayOfSTRUCT[k] = 
                        new STRUCT(localStructDescriptor, paramConnection,

            }

        } catch (Exception localException) {

如何把java中的arrayList轉化為oracle中的數組(array)

在PL/SQL中直接使用ORACLE數組

DECLARE

  l_rec cux_proxy_bid_award_tbl := cux_proxy_bid_award_tbl();
BEGIN
  FOR i IN 1 .. 5 LOOP
    l_rec.extend; -- 必須指定，否則會報指針越界
    l_rec(i) := cux_proxy_bid_award_rec(i, 100, SYSDATE, 'Y'); -- 如果是record也可以直接賦值cux_proxy_bid_award_rec,record的方式僅限於在PACKAGE中定義的TYPE，獨立的TYPE只能是OBJECT
  END LOOP;

  dbms_output.put_line(l_rec.count);
  dbms_output.put_line(l_rec(3).trading_partner_id);

END;
