Hello:
I am in process of re-writing an old Delphi app that ran CR reports via the VCL component to a .Net app that uses the .Net CR components.
As for versions, I am using VS 2013, .Net 4.5.1 and I installed CRforVS_13_0_14. The reports connect to an Oracle 10g database. The reports that I am testing haven't been created by me. Some of them are very old.
I am experiencing a weird behavior in the .Net version where the CR runtime uses tables from the wrong schemas while the designer (11.0.0.895) works fine.
At runtime I am using the following code to set the connection information:
| private ConnectionInfo CreateConnectionInfo() | |
| { | |
| ConnectionInfo connectionInfo = new ConnectionInfo(); | |
| connectionInfo.UserID = _reportRequestInfo.ReportRunUser; | |
| connectionInfo.Password = _reportRequestInfo.ReportRunPassword; | |
| connectionInfo.ServerName = _reportRequestInfo.ReportRunInstance; | |
| return connectionInfo; | |
| } |
| private static void SetDbLogonForReport(ConnectionInfo connectionInfo, ReportDocument reportDocument) | |
| { | |
| Tables tables = reportDocument.Database.Tables; | |
| foreach (CrystalDecisions.CrystalReports.Engine.Table table in tables) | |
| { | |
| TableLogOnInfo tableLogonInfo = table.LogOnInfo; | |
| tableLogonInfo.ConnectionInfo = connectionInfo; | |
| table.ApplyLogOnInfo(tableLogonInfo); |
| } | |
| } |
So, the report accesses a bunch of tables all in the same schema, let's say SCHEMA1. In design mode all works fine. However, at runtime, somehow CR assigns a different schema (or schemas) to some of the tables. The problem is that there is another schema in the database - let's call it SCHEMA2 - that contains some tables with the same names as in SCHEMA1. I used a session browser to see the open cursors that the CR runtime runs and I can see that it runs queries such as this one:
SELECT owner, object_type
FROM sys.all_objects
WHERE OBJECT_NAME = 'TABLE1'
ORDER BY object_type ASC
In some cases this returns more than one row, and unfortunately the first row is for the wrong schema, i.e. SCHEMA2.
What can I do to fix this? I have to admit, I am freaking out a bit. So far, I tested about 100+ reports, they all seemed fine, until today, when I compared the results for one report and the rows returned by the different versions of CR didn't match. I looked then at the queries both runtimes executed, the old version was fine, but the new one had used the wrong schemas for some of the tables.
Thanks
