這是是我的DAO類：如何解決這個值java.sql.SQLException：語句參數<number>沒有設置
public Map<String, String> issueOrUpdate(Map<String,String> employeeTempcardMap){
SlingDAO slingdao = new SlingDAO();
Map<String, String> issueOrUpdateMap = new HashMap<String, String>();
StringBuffer issueOrReturnTempcardQuery = new StringBuffer();
String empname="",functionkey="",tempcardnumber="",dateofissue="",dateofreturn="";
int empid=0,rowid=0,insertOrUpdateStatus=0;
Connection connection = slingdao.getConnection();
PreparedStatement issueOrReturnPS=null;
if (connection != null) {
try {
if(employeeTempcardMap.get("functionkey").toString().equals("issueTempCard")){
empid =Integer.parseInt(employeeTempcardMap.get("empid").toString()); //empname,tempcardnumber,dateofissue,rowid,dateofreturn
empname =employeeTempcardMap.get("empname").toString();
tempcardnumber =employeeTempcardMap.get("tempcardnumber").toString();
dateofissue =employeeTempcardMap.get("issuedate").toString();
//System.out.println("11111111111111111111111111111111111");
//System.out.println("empid : "+empid+" : empname: "+empname+" : tempcardnumber : "+tempcardnumber+": dateofissue "+dateofissue+"Status : "+applicationConstants.ISSUED);
issueOrReturnTempcardQuery.append(" INSERT INTO acct_tempcardhistory(empid,empname,tempcardnumber,tempcardstatus,issuedate,returndate) ");
issueOrReturnTempcardQuery.append(" VALUES(?,?,?,?,?,?) ");
}else{
dateofreturn = employeeTempcardMap.get("returndate").toString();
rowid = Integer.parseInt(employeeTempcardMap.get("rowid").toString());
issueOrReturnTempcardQuery.append(" UPDATE acct_tempcardhistory SET tempcardstatus=?,returndate=? ");
issueOrReturnTempcardQuery.append(" WHERE id ="+rowid);
}
issueOrReturnPS = connection.prepareStatement(issueOrReturnTempcardQuery.toString());
if(functionkey.equals("issueTempCard")){
//System.out.println("2222222222222222222222");
issueOrReturnPS.setInt(1, empid);
issueOrReturnPS.setString(2,empname.toString().trim());
issueOrReturnPS.setString(3, tempcardnumber.toString().trim());
issueOrReturnPS.setString(4, applicationConstants.ISSUED.toString().trim());

//issueOrUpdateMap.put("message","Temporary Card has been Returned by "+empid);
}
insertOrUpdateStatus = issueOrReturnPS.executeUpdate();
System.out.println(insertOrUpdateStatus + "row(s) affected");
if(insertOrUpdateStatus >0){
issueOrUpdateMap.put("message","Temporary Card has been issued/Returned to "+empid);
}else{
issueOrUpdateMap.put("message","Temporary Card has not been issued/Returned to "+empid);
}
connection.close();
// connection.commit();
} catch (Exception ex) {
ex.printStackTrace();
issueOrUpdateMap.put("message","Temporary Card has not been issued/Returned to "+empid);
} finally {
try {
slingdao.closeConnection(connection, null, issueOrReturnPS);
} catch (Exception ex) {
ex.printStackTrace();
}
}
} else {
issueOrUpdateMap.put("dbmessage","Connection not Established. Please Contact Vendor");
}
return issueOrUpdateMap;
}
}
UPDATE：
堆棧跟蹤：

當我印刷，我看到所有的價值，但仍然表明，
java.sql.SQLException: Statement parameter <number> not set.
相同的工作時更新，但它不適用於插入數據時，我也作爲一個字符串的日期。
請指導我如何去做或在哪裏做mistak？
問候
介意給堆棧跟蹤？有關於代碼中的行號的說明？ – 2012-07-17 08:38:40
請查看更新的stacktrace，它給出了我在DAO方法中調用DAO方法的行號，在DAO中給出了'insertOrUpdateStatus = issueOrReturnPS中的行號。的executeUpdate（）; ' – 2012-07-17 08:40:57
