java plsql 调用oracle数组类型

首先当然是在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中调用

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";
            //构造ArrayList
            array.add(obj);
        }

        OracleCallableStatement statement = null;
        OracleConnection oracleConnection = (OracleConnection)this.getOADBTransaction().getJdbcConnection();
        try{
            //将arraylist解析为STRUCT
            STRUCT[] arrayOfSTRUCT = createMyRows(oracleConnection, array);

            //此处使用引用的TYPE
            //不能调用在PACKAGE中定义的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("决标完成！", OAException.CONFIRMATION);
                this.getOADBTransaction().putDialogMessage(dialogMsg);
            }else{
                throw new OAException(retMsg);
            }

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

    }

    ////将arraylist解析为STRUCT
    private STRUCT[] createMyRows(Connection paramConnection,
                                   java.util.ArrayList paramArrayList) {

        int j = paramArrayList.size();
        STRUCT[] arrayOfSTRUCT;
        try {
            //此处使用定义的原始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++) {

        }

        return arrayOfSTRUCT;

如何把java中的arrayList转化为oracle中的数组(array)

在PL/SQL中直接使用ORACLE数组

DECLARE

  l_rec cux_proxy_bid_award_tbl := cux_proxy_bid_award_tbl();
BEGIN
  FOR i IN 1 .. 5 LOOP
    l_rec.extend; -- 必须指定，否则会报指针越界
    l_rec(i) := cux_proxy_bid_award_rec(i, 100, SYSDATE, 'Y'); -- 如果是record也可以直接赋值cux_proxy_bid_award_rec,record的方式仅限于在PACKAGE中定义的TYPE，独立的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;
