Database

I have a SQL query connected to a data source and to a database component on a form.
I have turned the login prompt to false on the database component so I dont receive a login box when I activate the query.

My problem is that I still receive a login box even though I have carried out the above. Am i missing something?

I am using Delphi 5 Professional and the query is performing a select on a SQL Server system.

Any suggestions would be great.
Thanks

is your query bound to the tdatabase?
(property databasename -> select here the name of the tdatabase)

Thats because your database requires a login, even though you shut it off, by telling the LoginPrompt = false


Try passing the login info using the Params property of the database.

You can set it at design time,

or

runtime

here is an example:

{------------------------------------------------------------------------------}
function TAdmin_DataModule.Connect_Database(aServer, aUserName,
aPassword : string; aDatabase : TDatabase) : Boolean;
var
 TmpStrList : TStringList;
begin
 TmpStrList := nil;
 Result := True;
   try
    TmpStrList := TStringList.Create;
    TmpStrList.Add('SERVER NAME=' + aServer);
    TmpStrList.Add('USER NAME=' + aUserName);
    TmpStrList.Add('PASSWORD=' + '');
    aDatabase.Params.Assign(TmpStrList);
   finally
    try
     aDatabase.Connected := True;
     Result := aDatabase.Connected;
     TmpStrList.Free;
    except
     Result := False;
     aDatabase.Connected := False;
     TmpStrList.Free;
    end; {try except}
   end;

end;

You probabely placed the Database component on a form ... and not on a DataModule and you probabely placed another query component on another form. You should place all the data acces components (query, table, database, datasources) in a DataModule and try to see if you get the login prompt.

And of course you must obviously link the form that uses the query with the data module.

Also if your dbms requires a uname and password then you will have to set those properties for the database.  I think you can set them at design time but I know you can set them at run time like was poseted above.

SCOTT78, yoy might want to try being a liitle more hospitable with your grading.

If you didn't get the answer you wanted, hold off until you get it. ( question = 1 day old)
