sql server使用全局临时表的Jsp页面出现 TDSExecuteRequest(TDSRequest).processReply(BaseWarning

连接数据库的文件源码： dataconn.java
package dataconn;
import java.sql.*;public class  dataconn{

String sConnStr = "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=BugFree";

}
catch(java.lang.ClassNotFoundException e) {
System.err.println("news_conn(): " + e.getMessage());
}
} public ResultSet executeQuery(String sql) {
rs = null;
try {

} 
catch(SQLException ex) {

System.err.println("aq.executeQuerystrSQL: " + sql);

//执行一些创建Table 的语句。
public void execute(String sql){

try{

}
catch(SQLException ex) { 
System.err.println("aq.executeUpdate: " + ex.getMessage());
System.err.println("aq.executeUpadatestrSQL: " + sql);
}
}

   public void closeStmt()
{
try{
stmt.close();
   }
catch(SQLException e){
e.printStackTrace();
   }
}
public void closeConn()
{

conn.close();
   }
catch(SQLException e){
e.printStackTrace();

一个使用全局临时表的jsp页面，源码
<%
    dataconn conn=new dataconn();
    
   conn.execute(" if object_id('#temp') is not null drop table #temp");    conn.execute("create table #temp(BugID int,BugTitle varchar(100)) ");
    conn.execute("insert into #temp select BugID,BugTitle from BugInfo");
    ResultSet rs=conn.executeQuery("select * from #temp where BugID>42");
   if(rs!=null)
   {
   
     while(rs.next())
     {
       out.print(rs.getString("BugID"));
       out.print(rs.getString("BugTitle"));
       out.println();
     }
   
   
   }
  
  rs.close();
  conn.close();
  
      %> 
  
只要连续刷新两次这个jsp页面，myeclipse 会自动跳动debug，出现下面提示
