oracle通过存储过程上传list保存功能

太阳不下山

一、创建oracle 需要保存的数据类型type和存储过程produce

create TYPE "AL01TYPE"                                                                                                                  as object
(

  aac003     NVARCHAR2(100), 
  aac002     NVARCHAR2(50), 
  aat001     NVARCHAR2(50), 
  aat002     NVARCHAR2(50), 
  aat013     NVARCHAR2(20), 
  aae011     NVARCHAR2(20), 
  aae036     NVARCHAR2(20), 
  aah002     NVARCHAR2(100) 
);
 
create type AL01TYPELIST as table of AL01TYPE;
 
-- auto-generated definition
create PROCEDURE SP_HFSZHDA_DOUPLOADAL01(LIST   IN   AL01TYPELIST,
                     po_message OUT VARCHAR) IS

  v_object  AL01TYPE;
  le_error EXCEPTION;
  P_renum number(20);
 
  v_aah002  VARCHAR(100);
  ls_count number;
  ls_aaf025 VARCHAR(50);
 
BEGIN
  P_renum  := 0; --初始化
 
  FOR I IN 1 ..  LIST.count LOOP
  P_renum := 1 + P_renum;
 
    v_object := LIST(I);
 
 
     select   replace(utl_raw.cast_to_varchar2(utl_raw.cast_to_raw(v_object.aah002)),unistr('\0000'))  into  v_aah002 from   dual;
 
    begin
    Select count(0) into ls_count from az03 where aat001 = v_object.aat001 AND aat012 = '1';
    if ls_count=0 then
       po_message := '号：'||v_object.aat001||' 状态异常请核对后再上传！';
       RAISE le_error;
       end if;
 
     Select count(0) into ls_count From AL01 where aaj022='1' and aat001=v_object.aat001 and aah002=v_aah002;
     if ls_count =0 then
    -- 开始插入信息
    select  SQ_AAF025.nextval into ls_aaf025 from dual;

二、通过过程上传list

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

import java.sql.Connection;
import java.util.List;
 
/**

public class OracleUtil {
  /**
   * 根据数据库中你的type将List组装成Array
   * @param con
   * @param OracleObj
   * @param Oraclelist

   */
  public static ARRAY getArray(Connection con, String OracleObj, String Oraclelist, List<Object[]> objlist) throws Exception {
    ARRAY array=null;
    C3P0NativeJdbcExtractor cp30NativeJdbcExtractor = new C3P0NativeJdbcExtractor();
    OracleConnection connection = (OracleConnection) cp30NativeJdbcExtractor.getNativeConnection(con);
 
 
    if (objlist != null && objlist.size() > 0) {
      StructDescriptor structdesc = new StructDescriptor(OracleObj, connection);
      STRUCT[] structs = new STRUCT[objlist.size()];
      for (int i = 0; i < objlist.size(); i++) {
        Object[] result= (Object[]) objlist.get(i);
        structs[i] = new STRUCT(structdesc, connection, result);
      }
      ArrayDescriptor desc = ArrayDescriptor.createDescriptor(Oraclelist,connection);
      array = new ARRAY(desc, connection, structs);
    }
 
    return array;
  }
 
}

List<Object[]> arrList = new ArrayList<>();
    //解析数据datamap
    for (Map<String, String> dataMap : dataMaps) {
      //创建保存对象
      Object[] objects =new Object[]{
 
          dataMap.get("aac003"),
          dataMap.get("aac002"),

      };
      arrList.add(objects);
 
    }
 
 
 
//开始调用过程
    long startTime=System.currentTimeMillis();
    Connection connection = null;
    CallableStatement sqlres = null;
    String sql = "call SP_HFSZHDA_DOUPLOADAL01(?,?)";
    String msg = "";
    try {
      connection = dataSource.getConnection();
      ARRAY paramArr = OracleUtil.getArray(connection,"AL01TYPE","AL01TYPELIST",arrList);
 
      sqlres = connection.prepareCall(sql);
      sqlres.setArray(1, paramArr);
      sqlres.registerOutParameter(2, Types.VARCHAR);
      sqlres.execute();
      msg = sqlres.getString(2);
 
      long endTime=System.currentTimeMillis()-startTime;
      System.out.println("上传后获取的返回参数为："+msg+"||耗时："+endTime/1000+"秒");
 
    } catch (SQLException e) {
      e.printStackTrace();
    } catch (Exception e) {
      e.printStackTrace();
    }finally {
      try {
        if (sqlres != null) {
          sqlres.close();
        }
        if (connection != null) {
          connection.close();
        }
      } catch (SQLException e) {
        e.printStackTrace();
      }
      if (!"ok".equals(msg)){
        throw new BusinessException("上传失败！"+msg);
      }
    }
