What can be done to resolve the exception:
CrystalDecisions.CrystalReports.Engine.InternalException: Failed to open a rowset.
This is a generic error in Crystal Reports whenever the report query fails. There can be a number of causes. If your report was targeted to a specific database and then the database was changed without updated the report, this can cause it. It can also be caused by something in the query itself failing, such as if the report is based on a stored procedure that doesn't exist on the database against which the report is running. Try verifying the database for the report.
As said this is a generic error, and like all such errors it's a very frustrating one. The problem is that VS 2003 has no preview option for crystal reports so it's hard to track down the source of the problem. So best way to solve this is to create a blank project in vs 2005 or later, import the crystal report, and run preview. You will get a more specific error then.
I had the same issue, and received this error message:
One ore more fields could not be found in the result set. Use Verify Database to update the report.
Error in File filename {9FEE6406-1613-409A-B9BD-C5FDA24E3DEE}.rpt:
The rowset column could not be found.
I was using a stored procedure to collect data for the report, and sure enough I was passing an invalid parameter for the SP. Double check the type and value of the parameters if you are using a SP to populate the report data.
Good luck!
I have also gone through same error with report having sub reports. Issue resolved as i switch to each sub report and make it verify again with database/tables/views.
This is caused by some discrepancy in your relations, like opposite left joins or something similar. CR has also the bad habit to create 'default' links each time you modify the list of tables and views needed for the report. It can even sometimes automatically create recursive links that might not be viewable 'at once' in the relations screen.
If you cannot find which relation(s) is causing the trouble (sometimes it is not so obvious), you'll have to make some trial & errors test by adding/removing tables from your report.
Every time you add a new table in crystal it adds its own links on already linked tables, some times it even links the 2 fields from the same table.
Make sure you know your links in order to go through after you add a table and scroll all tables to see for any links create from to the same table
I received :
CrystalDecisions.CrystalReports.Engine.InternalException was unhandled
Message=The Report Application Server failed
Google brought me here. For those that have similar problems.
For the record: I had a byte[] array with an image and removed the log from the report and the error stopped. I now have to figure out what I have done wrong with the logo.
I had this problem - we use SQL logins for our security (not integrated / DSN connections)
By granting execute permissions to the user for my stored procedure I fixed the problem.
Really, really couldn't hate Crystal more for their exception masking - let this be a lesson to all programmers;
Try
'your code here
Catch
Throw new exception("Hey, here's a really friendly but completely useless error message")
End Try
will result in pain for future developers - DON'T DO IT!
When you verify your database it might tell you that it is up to date, in that case you have two more options to check for:
a) Refreshing the report (a lightning-shaped icon), if you have a problem with a field, such as a SQL Field, it will give you the error and then show you the edit window for the field.
b) Running the query directly on SQL, if there is a problem with the query itself you will also get this message in Crystal but SQL will tell you exactly what went wrong.
Check Changing Crystal Report Database logon information at runtime in VS2005 for help.
Important line in it is:
table.Location = Database & ".dbo." & table.Name
For me, the problem was fixed when I logged of and logged back to the SQL server that the report was connecting to
In your store procedure If you are using
SET NOCOUNT ON;
Then just remove this
--SET NOCOUNT ON;
Now verify your report database, build & run your solution.

I have crystal report that was working before database upgrade. It is only one report that doesnt work. So I would not think of a driver issue.
I am able to test this report using CRs client tools, design and then preview. The preview does not bring any data. A single parameter is used and I am sure there is data because the data is retrieved if I create a new crystal report and also verified the SQL. (So there is no question about the no data or any missing links -- its a simple view).
This cannot be a driver issue as well, as all other old reports still work.
Have also tried deleting all the field's from the report, then add a single/simple new table and preview, still no data is showing.
Are there any logs inside crystal to investigate ? have tried ODBC.logs doesnt help as doesn't say what happens inside crystal reports after retrieving the data from database.
Thanks.

I've had this problem multiple times where my report comes up with empty fields. This may not be your cause, but what fixes it for me is to make sure that the dataset/table matches is referred to by the same name everyplace. In the xxxxxxDataset.xsd file, that table that's pictured should be the same name that's used in the function GetData() As System.Data.DataSet in your .NET object that uses the stored procedure to get the data. (You may call your function something other than GetData().) So try changing the ds.Tables(0).Tablename = "xxxxxxxTable" to match what the table in the xsd file is called.
I have performed this process numerous times with other Reports but this one Report is not working as it should.
Essentially, I am trying to point a report at a new server where the stored procedure is EXACTLY the same as on the previous server. I am using the Verify Database functionality to do this. But when I point at the new server and enter parameters, CR prompts me to re-map the fields. This would be only slightly annoying if the Map Fields window actually displayed the returned columns from the new server.
But, as you can see from the image, even with the 'Match type' unchecked, no columns from the stored procedure display to be mapped. I have clicked on every field in the report but none of them show any columns to map to.
I have also tried changing the Database Location first before trying to verify, but that doesn't make any difference.
Has anybody else seen this? Is there any sort of workaround?
I found my solution. Kinda dumb, really.
My stored procedure calls another stored procedure. I commented that call out and tried to Verify the Database and it worked.
Apparently Crystal Reports doesn't handle procedures that call other procedures very well when trying to map fields.
I'm creating a 'SectionReport' (Active Reports V.9), and am dragging bound fields from the 'Report Explorer' directly onto the report. I've written the SQL query, which executes and returns the correct results as expected.
However, only a small portion of the bound fields are displaying data from the table.
Again, when I execute this in the 'Query Designer', I see all data. When I save that exact query, only some of the data is populated on the report.
This process seems so straight forward and yet I seem to be missing something.
Please help and thanks in advance!
So you're saying the data is returned but not showing up in some of the fields? Have you checked the binding for each of those fields?
Can you step with the debugger and verify that in the detail_format even there is data in report.fields for those records that have missing values.
can you add debug statements that print each field value in the detail_format event.
based on what you described all I can offer is some diagnostics techniques. If you'd like please send your report to our support team and we can properly inspect it and help you out http://arhelp.grapecity.com/
If you are using the enduserdesigner sample or the pre-compiled exe that comes with the installer, can you please make sure that the PreviewPages to a larger number instead of 10.
You can change the value by follwing these steps. in report exploer, double click the settings node. go to gloabal settings tab and change the previewpages value.
If this is not the case, please attach the report. There are no other settings that will cause this.
I've just begun using the BIRT report designer for Eclipse to create reports from data in a MySQL database. When attempting to preview the result set from a created data set, I receive the following error:
SQL error #1:You have an error in your SQL syntax; check the manual
that corresponds to your MySQL server version for the right syntax to
use near 'OPTION SQL_SELECT_LIMIT=500' at line 1
I understand that this syntax is invalid with MySQL, as it should be
SET SQL_SELECT_LIMIT=500
However, I cannot figure out if/where I can make this correction, as it is added automatically by the report builder when generating the preview.
Furthermore, in the IDE preferences, I have selected the 'No Limits of number of rows to display' option, trying to bypass this statement altogether, but continue to receive the same error, indicating that it still is trying to preview 500 or less rows, even after deleting the first data set definition and remaking it after the option was changed and restarting Eclipse.
If anyone has any suggestions for either changing the syntax or getting the No Limits option to work correctly, I would greatly appreciate it.
Was actually able to figure out the issue with getting the correct syntax thanks to this SO post regarding Netbeans. The MySQL JDBC driver simply needed to be updated. Preview no longer generates depreciated syntax.
I'm currently modifying an existing report and replacing the data source used in the report. The reason I'm not creating a new report is because the report is laid out exactly how I would like it to be laid out. I've updated every field with the new data source fields and checked that the formulas are all correctly formatted.
Everytime I attempt to view the report (I'm using the Crystal Reports tool in VS 2010), I get the error "The group section cannot be printed because its condition field is nonexistent or invalid. Format the section to choose another condition field."
I've read another question from stackoverflow but still can't seem to find out what is wrong with my report.
First of all, why doesn't Crystal tell you more specifically what is wrong?
Any suggestions or hints?
My first thought is that you didn't update the Groups correctly when you switched backends. Go into your Group Expert. Do you see any groups simply labeled with question marks? If so, there's your problem. Go into the options for that group and choose an appropriate grouping field.
Also, use the Database->Verify Database command to look for other possible errors.
As for your question about Crystal's design, I believe that it does give reasonably accurate error messages, especially considering everything that can go wrong with any one report.
