Question

Hi i am trying to compile my jsp page and jave page is coming up with an error on this method.
can some1 tell me if i have written this incorrectly.     
     public ResultSet getCampaign(String userId, String campId) throws SQLException
          sqlers = "SELECT *, Clients.Name FROM Campaigns, Users, Clients WHERE Campaigns.UserId = Users.UserId and Campaigns.ClientId=Clients.ClientId AND Campaigns.UserId="+userId +" and Campaigns.CampId="+campId+";";
          ResultSet rs = stmt.executeQuery(sqlers);
          return rs;
this is wot my compiler says:
[javac] symbol : variable sqlers
[javac] location: class sales.Sales
[javac] sqlers = "SELECT *, Clients.Name FROM Campaigns, Users, Clients WHERE Campaigns.UserId = Users.UserId and Campaigns.ClientId=Clients.ClientId AND Campaigns.UserId="+userId +" and Campaigns.CampId="+campId+";";

Answer 1

Did you declare sqlers as a String somewhere?
String sqlers = "SELECT *, Clients.Name FROM Campaigns, Users, Clients WHERE Campaigns.UserId = Users.UserId and Campaigns.ClientId=Clients.ClientId AND Campaigns.UserId="+userId +" and Campaigns.CampId="+campId;
ResultSet rs = stmt.executeQuery(sqlers);
return rs;Also, you shouldn't put that semi-colon at the end of your SQL.
