I have a report that runs one query in 9 different Oracle databases. If one of these databases is down, the whole report bombs. Is there any way to set it so it ignores this failure and proceeds with the rest of the report?
I'm not sure if there is a way to do what you're wanting within RS, but here's my idea:
If you can call from a SQL database -
Set up linked servers on a sql server.
Wrap the call in a stored procedure and return an alternate data set if the call fails to the linked server.
You could probably do something similar if there is an oracle server you can use.

I am developing reports for a system using Workforce Time and Attendance. The system uses an Oracle database, Crystal Reports, and (I think) Business Objects. My reports use parameters. I want to know how those parameters are being used. Is there a way to see the actual SQL that's being sent to the database server?
Please don't respond with Database | Show SQL Query... That shows me the SQL I created (with the parameter names). I want to see what the database server is receiving.
I have a dashboard in Tableau which pulls data from about 10 tables in a SQL database.
These tables are refreshed at various times of day. There are occasions where one of them is not available (or has been deleted and awaiting rebuild)
However when I open my tableau dashboard on the server it wont let me see any of it. Not seeing the data from the missing table is fine but the majority of the data that does not come from that table is unavailable too.
I get this error
An unexpected error occurred. If you continue to receive this error please contact your Tableau Server Administrator.
TableauException: [Microsoft][SQL Server Native Client 11.0][SQL Server]Invalid object name 'dbo.survey_order_info_fy16_TV_L'. The table "[dbo].[survey_order_info_fy16_TV_L]" does not exist. Unable to connect to the server "dbedwro.vistaprint.net". Check that the server is running and that you have access privileges to the requested database.
"survey_order_info_fy16_TV_L" being the missing table but not one I'm bothered about right now.
Is there an option that might help me see all the other data?
I am not sure if it's possible to avoid this behavior.
If there isn't there is a workaround for that by creating extract of these tables and storing them on the Tableau server. You can then use these extracts instead of the tables on the DB and just refresh them either by schedule if you know when the tables are available again or from the SQL server (eg. with SSIS by triggering the refresh once the data is available again).
Advantage of that would be that
you can refresh them independently and always have the latest data
it performs better than an SQL connection
you don't jam your SQL server with connections (in case you have a lot of users accesing)
you can filter and select if you didn't want your users to get access to the full dataset
disadvantages:
you will have to create one extract per table, and replace all data sources in workbooks you already use
It's a matter of creating a workbook, connecting to the source (adding filters or hiding fields) and publishing it to the server. Details of that can be found here:

I wrote a stored procedure that calls openquery to a linked server to get data from a remote postgresql server and fill a table with that data. This is working fine. The stored procedure needs 3 parameters.
When I try to call the stored procedure from Report Builder 3.0 gives me error
7350 (cannot get the column OLE DB provider MSDASQL from linked server "name").
I already verify the allow in-process parameter in MSDASQL.
I can't find a solution for this. If I run the stored procedure from Mgmt Studio, it works fine. I'm using SQL Server 2012.
The report only have to show the file data by row. I can run the stored procedure and the report separately and works but I have to do this manually, my requirement needs a report subscription, so have to be automatic.
Any idea how to solve this or a workaround?
PD: sorry for my english, and thank you in advance.
Well I had to make separates works, so create a job that run the store procedure, generate the info on a table, and then run report reading the info from the table. This works.
Thank you all.
Here's the situation: I receive reports written by a vendor which are all developed on their own Oracle DB. Normally, there is no issue in setting a new datasource to our own Oracle DB, but this one report in particular is not playing nicely.
The report in question has 8 SQL Expressions, and a subreport with an additional 3 SQL Expressions (I mention this because I suspect this may have something to do with it, but not sure. Almost like CR is attempting to verify the SQL Expressions on the old DB). I'm able to update the data source of the subreport just fine, but when I try it with the main report, Crystal prompts me repeatedly for the login to the OLD DB where the report was developed (which I obviously do not have access to). The prompt is inescapable and I have to terminate Crystal's process each time.
I've tried unchecking all report and database checking/verification options in CR to no avail. If anyone has any advice as to what I could try next, it would be greatly appreciated!
EDIT: Well, it looks like all I had to do is close the login window a BILLION times (OK, more like ~16, twice for each SQL Expression?). Leaving the question open, though, to see if there is any way to avoid having to go through this for future reports.
EDIT EDIT: Some more details. This is still happening with CR 2008 SP3 attempting to connect to an Oracle 11g database with 11g R2 client. I'm not sure about how these reports were developed, but it was with CR XI at the earliest.
I have seen this w/ migrated reports before, but it's been loong ago.
If you had to do it a million times, I would have guessed that you actually had 999,999 sub-reports -- all to the same old data source, all needing verification or failure to try the new data source. Sorry, I just re-read... I meant to put 'a BILLION' minus 1.
Did you check your TNSNames against (whatever config supplied by the vendor)?
Are you using the same driver used by the vendor Oracle reports? (Oracle driver vs MS ODBC for Oracle vs CR ODBC for Oracle vs MyPrettyPony ODBC Dri...)
Did you go through the Set DataSource exercise in CR?
Can you save the subreports seperately and run them individually w/out needing the (insert some large number) login window closures?
Can you create a new report, set to your own Oracle data source? (I have to assume this one is ok, based on your comments)
If you copy the Show SQL Query and use that as a Command query in a new report, does that run? (Rinse and repeat as sub-reports).
(I'm stalling for time as I search my memory for the last time I experienced the same...)
Failed to load rowset. Incorrect syntax near...this error comes when I run the program. I want to show report in a crystal report. I have many tables linked by key. Anyone can suggest
I don't know what kind of database you're pulling from, but you may want to do your joins before you pull it into CR.
If that doesn't do it, you may want to save your data to a temporary table as well, then link CR to the temporary table.
In most cases this means that Crystal Reports has build an incorrect SQL statement. This happens sometimes as f.e. with SQLBase. Mostly that is difficult to solve.
Sometimes it can be solved by using a different database driver, f.e. try to use OLEDB instead of ODBC.
If that doesn't help, please provide more details:
Database (SQL Server, Oracle, or ...)
Database driver: ODBC, OLEDB, or ...
Query (via menu [Database, Show SQL Query).
