Question

What is the RAS syntax to logon and change the database location when using "Command Table" in the Crystal Report?

Asked by: CDL2

I have a Crystal Report (v10) that uses a Command Table.  The report works fine in Crystal, but I am unable to run the report through my application using RAS.  Normally I use the SetTableLocationByServerDatabaseName command so that I can change the database location from the development database to the production database.  This doesn't seem to be working, presumably because of the command table.  I receive an HTTP 500 error, "The website cannot display the page".

Here is the RAS code, which works fine for the reports that use a view or table.  

clientDoc.DatabaseController.SetTableLocationByServerDatabaseName "commandtable name","servername","","uid", "pwd"

For the table alias I have tried both the command table name, and also leaving it blank.

Any suggestions would be appreciated.

Also, if someone has an example of the code required to put the sql command directly in the code instead of using the command table in crystal, I would appreciate it.

Thank you!

Are you using a COMMAND as the datasource for the report?

by: CDL2Posted on 2008-12-11 at 08:45:00ID: 23149881

Yes.

 

by: mlmccPosted on 2008-12-11 at 09:05:25ID: 23150066

A command is much like a stored procedure.  I am not sure if you can change them at runtime.

I'm not trying to change the command at runtime, just the server name.

A co-worker figured out how to do this.  Instead using SetTableLocationByServerDatabaseName, it is necessary to create a property bag and modify the server name with GetConnectionInfos.

Thanks.

Could you show the code required to do this?

Here's the code:

Set pbag = ObjFactory.CreateObject("CrystalReports.PropertyBag")
Set oDBInfo = clientDoc.DatabaseController.GetConnectionInfos(pbag).Item(0)
oDBInfo.Attributes.Item("QE_ServerDescription") = "servicename"
oDBInfo.Attributes.Item("QE_LogonProperties").Item("Server") = "servicename"
oDBInfo.UserName = "reportuserid"
oDBInfo.Password = "reportpassword"

Set newMainTable = clientDoc.DatabaseController.Database.Tables.Item(0).Clone()
newMainTable.ConnectionInfo = oDBInfo
clientDoc.DatabaseController.SetTableLocation clientDoc.DatabaseController.Database.Tables.Item(0), newMainTable
