将数组中的对象插入sql

Question

我的代码

public void commitContractor()
     {
         for (Contractor c: Contractor.contractorArray)
         {
             String dbHolder = "";
             dbHolder = "INSERT INTO SYSTEM.CONTRACTOR(CONTRACTORID, FIRSTTNAME, LASTNAME, MIDDLEINITIAL, HOUSENUMBER, STREET, CITYCOUNTY, STATEABB, COUNTRYABB, ZIPCODE, FEE, LASTUPDATEDBY, LASTUPDATED) VALUES(";
             dbHolder += c.getContractorID() + ", ";
             dbHolder += "'" + c.getFirstName() + "', ";
             dbHolder += "'" + c.getLastName() + ", ";
             dbHolder += "'" + c.getMiddleInitial() + "', ";
             dbHolder += c.getHouseNumber() + ", ";
             dbHolder += "'" + c.getStreet() + "', ";
             dbHolder += "'" + c.getCityCounty() + ", ";
             dbHolder += "'" + c.getStateAbb() + "', ";
             dbHolder += "'" + c.getCountryAbb() + ", ";
             dbHolder += c.getZipcode() + "', ";
             dbHolder += c.getFee() + ", ";
             dbHolder += "'" + c.getLastUpdatedBy() + "', to_date(";
             dbHolder += c.getLastUpdated() + "','yyyy-MM-dd'),')";

             System.out.println(dbHolder);

                sendDBCommand(dbHolder); // sends sql line to db
//                dbHolder = ""; 
         }
     }

在此结束
