在netbeans中使用向量填充表

我正在做一个与献血有关的项目，这是我的搜索框架，任何人都可以搜索血液是否可用。问题是我有两张名为user_don的表，其中保存了最后一次捐款的入场号和日月份年份，以及保存了入场号码姓名电话等的name_don_det。我想从两个表中检索数据并显示在同一时间使用矢量或别的东西一起。这是我所：在netbeans中使用向量填充表

user_view(String d1, String d2, String d3) throws ClassNotFoundException, SQLException { 
    initComponents(); 
    int a = Integer.parseInt(d1); 
    int b = Integer.parseInt(d2); 
    int c = Integer.parseInt(d3); 
    int year=a; 
    int month=b; 
    int date=c; 
    String query; 
    String query1; 
    if(b<=6) 
    { 
     year=a-1; 
     month=b+6; 
     query="Select * from user_don_det where Year<="+ year +" and Month<="+ month +""; 
     query1="SELECT * FROM `user_det` WHERE `Admission`=(Select Admission From user_don_det where Year<="+ year +" and Month<="+ month +")"; 
    } 
    else 
    { 
     month=b-6; 
     query="Select * from user_don_det where Month<="+ month +" or Year<="+ year +""; 
     query1="SELECT * FROM `user_det` WHERE `Admission`=(Select Admission From user_don_det where Month<="+ month +")"; 
    } 

    blooddonation.dbconnectivity db=new blooddonation.dbconnectivity(); 
    ResultSet rs=db.q_execute(query);  
    ResultSet rs1=db.q_execute(query1); 

    Vector data=new Vector(); 
    while(rs.next()) 
    { 
     Vector row=new Vector(); 
     row.addElement(rs.getInt(1)); 
     row.addElement(rs.getInt(2)); 
     row.addElement(rs.getInt(3)); 
     row.addElement(rs.getInt(4)); 

     data.addElement(row); 
    } 
    while(rs1.next()) 
    {Vector row=new Vector(); 
     row.addElement(rs1.getString(1)); 
     row.addElement(rs1.getString(2)); 
     row.addElement(rs1.getString(6)); 
     row.addElement(rs1.getInt(8)); 
     data.addElement(row); 
    } 


    Vector head=new Vector(); 
    head.addElement("Admission No"); 
    head.addElement("Date"); 
    head.addElement("Month"); 
    head.addElement("Year"); 
    head.addElement("Name"); 
    head.addElement("Email"); 
    head.addElement("Sex"); 
    head.addElement("Phone"); 

    DefaultTableModel model=new DefaultTableModel(data,head); 
    tab.setModel(model);

}

这是当前的错误状态：

哪行'user_view.java：55'？发布[MCVE]：发布最低限额以显示您的问题。（写一个最简单的案例是一个很好的调试技巧，这样做很可能解决你的问题。） – c0der

错误得以解决.. IN是用来代替=
