Login Failed when there are 2 connections in SubReports - even when applying table wise correct connection info

Posted on 2004-08-03
Last Modified: 2008-01-09
Hi Expert,

I have created a Report with a Sub report and both have 2 connection information. Viz. Main Report has 2 connections - 1
Connection to data source using Stored Procedure (SQL Server) and second connection to data source which provides fields
based upon Language selected say English, Spanish etc. so we have one separate Language Database. Similar is the case with
Sub Report. Now when I am passing the connection info as shown below in Steps to reproduce, then 1st page gets displayed
perfectly but clicking on the second page gives the Login Failed Error, but if I have only 1 connection in both main
Report and sub report the same code works fine. Is there any resolution to this???

What version of Crystal.  Version before CR9 did not like multiple sources for the data thus the need for subreports.  CR9 supposedly allows multiple ources but only if they are the same database type.  It may be that a stored proecedure and your othewr connection are viewed as different types.

Does the report run from the Crystal designer?

I agree with mlmcc and I can confirm from my own experience that CR9 doesn't like combination of SP and db table even if they're on the same database.  

I suggest that you either modify the SP to return the information from the ancillary table as well as the data currently being sent back or have your main report connect only to the SP and make a subreport to connect only to the table.

Hi Frodoman and Mlmcc,

I am using CR10.

Further to make it more clearer,

Eg. 1. Crystal report without sub report :

1 connection to DB1 and another connection to DB2 - working perfectly both in Designer and Viewer.

Eg. 2. Crystal report with sub report :

Main Report - Connection to DB1
Sub report - Connection to DB2

Working perfectly in Designer....but causing problems in Viewer (.NET), also first page works perfectly 7/10 times, while clicking 2nd page give me the Login fail error.

Thanks for help....waiting for reply.

It looks like you're using multithreading in your application.  Have you verified that the database drivers you're using are thread safe?  If not that would explain the intermittent errors.

I don't have CR10 but I know in CR9 the ODBC drivers were thread-safe only for SQL Server and Sybase.  Most but not all native drivers are thread-safe.  You can probably check your CR help for a list of them - I found it in CR9 help searching for "thread-safe".
