if you are using ADO, set the ConnectionTimeOut property of the Connection object to a short period (default is 30 seconds).

i'm can't see what programming category you've posted this in .. but in vb

private sub mysubname()
  on error goto err_mysubname
      ' my sql server connection stuff
      exit sub
  err_mysubname
      msgbox "An error occured connecting to SQL Server"
      exit sub
end sub




in java

try{
    // your SQL Server connection stuff.

}catch(SQLException SQLE){
     System.out.println("An error occured connecting to SQL Server");
     throw new Exception("SQL Server connection error");
}catch(Exception e){
     System.out.println("Error : " + e.toString());
     throw new Exception("Error : " + e.toString());
}

either solutions could have worked.. we didn't get a reply for him.  I recommend split.

 

by: emoreauPosted on 2004-02-09 at 17:37:31ID: 10317888

The question is about raising an error IMMEDIATELY if a parameter is invalid. There is nothing in your code snippets that returns the error faster!

 

by: Howie_LyPosted on 2004-02-09 at 17:45:14ID: 10317996

He was rather vague not specifying which language his program was written in or how he was connecting (e.g. ADO or Java).. we couldn't automatically assume it was in ADO.

If comments are not appropriate to the asker, he (she) has to come back and be more specific. Allmost all database access technology has something like the ConnectionTimeOut.

"If comments are not appropriate to the asker, he (she) has to come back and be more specific."

exactly.

 

by: emoreauPosted on 2004-02-09 at 19:09:03ID: 10318726

since he (she) didn't come back, I suppose that the only related comment is the one that answered!

 

by: Howie_LyPosted on 2004-02-09 at 19:19:35ID: 10318778

if it's about the points man geez you can have it ... i just don't agree that yours is the only correct solutin.

 

by: emoreauPosted on 2004-02-09 at 20:00:09ID: 10318993

It's not the points!

The question is : "But i need if i give wrong server name or password immediately rise errror"

Nothing in what you propose raise the error IMMEDIATELY.

 

by: Howie_LyPosted on 2004-02-09 at 20:13:36ID: 10319058

Well if he's using java and tries to log in with an incorrect username/password connection then he'll get a nullpointer exception.. why can't he just catch that?

That's pretty much immediate isn't it?  Never said your solution was wrong .. but there are others.

 

by: emoreauPosted on 2004-02-10 at 02:51:07ID: 10320875

The error is usely triggered after a timeout (normally 30 seconds).
