SQLException未找到列

Question

也许这是一个愚蠢的问题，但我真的试图解决问题而没有成功，我有一个名为StockNivSens的方法如下：

public void StockNivSens(){
    int nbrRoles = getNbrRoles();
    String objID;
    int sumPerm = 0, pName = 0;
    String sql = "SELECT objectdwID, peName "
            + "FROM permissiondw pdw, securityrole sr "
            + "WHERE pdw.securityPropertyID = sr.securityPropertyID "
            + "AND pdw.RoleID = sr.RoleID";
    try {
        pst = conn.prepareStatement(sql);
        res = pst.executeQuery();
        while(res.next()){
            objID = res.getString("objectdwID").toString();
            pName = Integer.parseInt(res.getString("peName"));
            ....

当我执行它时，它会给我一个SQLException错误：

java.sql.SQLException: Column 'peName' not found.

但是当我在Mysql Workbench上执行它时它会起作用：

也许解析是导致错误的原因，但我需要 int 格式的变量pName（它在数据库中是 varCHAR ）

编辑1：

当我添加：

System.out.println(objID);
System.out.println(pName);

它显示了结果。

16
3

然后打印错误。

编辑2：

我用明确的一个替换了impecit sql：

String sql = "select objectdwID, peName "
                + "from permissiondw pdw inner join securityrole sr "
                + "WHERE pdw.securityPropertyID = sr.securityPropertyID"
                + "AND pdw.RoleID = sr.RoleID";

错误仍然存​​在。
