How to use oracle functions in Crystal Reports XI using Oracle Server

Hi all,
Is it possible to use oracle functions in Crystal Reports XI using Oracle Server as Data Source.
If i try to use a procedure,i am getting error with message "Invalid Arguement Provided".
Functions are not visible objects like tables,views and stored procedures.
The jdbs driver i m using is oracle.jdbc.driver.OracleDriver.

I think it is not possible to add functions in crystal directly for any database. You need to use those functions in a stored procedure and add that storedprocedure as a datasource.

How to call C++ function in Crystal report

Hi,
i am working on serious issue now, i need some help, Could you please tell me how can i call my C++ method in crystal report designer (may be formula editor), i can see only this support VB and Crystal basic.
Regards,
Prabhakar J.

Hi Prabhakar,
The name of the UFL dll must begin with U2L. Rename your and if it's compile properly CR should find it when loading all of it's dependencies.
Check the developers help file and search for Custom User Function Library.
I should also mention that UFL's only support MBCS string formats so if you define them they must be defined this way or CR will have problems passing them from/to your UFL. CR uses UNICODE format internally but the UFL bridge will thunk them to MBCS format on the way out and expect that format on the way in. There is a possibility of data loss in the conversion routines.
Thank you
Don

Using Sql Functions in Crystal Reports

Can SQL table-valued functions be used in Crystal Reports? The only options I see in the Database Expert are Tables, Views, and Stored Procedures.

Hi Dan,
Are you referring to user-defined SQL functions? If yes, then these are not accessible in Crystal Reports.
You would need to create a stored procedure which calls the function and does the processing and use this procedure in CR.

How to implement the Oracle Group by function in Crystal reports?

Hi all,
In SQL, for example we have a group function like:
select district,state, country, continent, sum(no.of people) from world.
Now, How to implement this group function in crystal reports? Please advise.
Thanks in advance..
Regards,
sriram

Hi Vinay,
Thanks for the prompt reply.
In one of our report, we are supposed to perform group by for 14 columns to get sum of 3 columns and there by displaying 17 columns in the report.
When we tried in crystal reports to implement this oracle group by functionality:
1. We created 14 groups from the Insert->Group option.
2. By performing this, we got 14 group sections vertically(one inside the other).
3. Then we created the sum(15th column),sum(16th column), sum(17th column) by Insert->Summary option.
4. We suppresed all the group sections except for the last group.
5. Then, dragged all the groups to the last group section along with the summary fields.
This is how, we tried to acheive the oracle group by function in Crystal reports.
Please advise, whether our approach is right. If not, please suggest the appropriate approach with a bit detailed explanation.
Thanks,
Sriram.

How to publish crystal report designed using SAP Add-on toolbar

we have installed the crystal report designer V10 and the SAP add-on on the desktop.
we have designed a formatted report in crystal report designer using an existing BW report that was created using Bex query designer. After this we saved the crystal report back in BW to a role.
We have not published the report to crystal enterprise server, since the connection to same is not in place.
We would like to know how to publish this report in Enterprise portal ?
Can we bypass publishing the report to crystal enterprise server and publish the report on browser or through EP ?

Using a SQL user-defined function in Crystal Reports XI

Post Author: JoannKarp
CA Forum: Formula
Is it possible to use a user defined function in SQL and use this in multiple Crystal reports?
JoannKarp

SELECT COALESCE(ufn_GetAddressByBusinessEntityIDandAddressTypeID(table1.BusinessEntityID,712),ufn_GetAddressByBusinessEntityIDandAddressTypeID(table1.BusinessEntityID,712)) AS Zipcode
FROM table1
Nope. This is two function calls. coalesce(a, b, c, ...) is just syntatic sugar for
CASE WHEN a IS NOT NULL THEN a
WHEN b IS NOT NULL THEN b
WHEN c IS NOT NULL THEN c
END
But if you use isnull it's a different matter. (But isnull() permits two arguments.)

How to use CRAXDDRT.DLL in crystal report 2008?

Hello All,
We have purchased Crystal report 2008 Full software.
We need to insert BLOB field into Crystal report 2008 at runtime using *CRAXDDRT.DLL*.
How can I insert OLE object and bind it at Runtime using crystal report 2008?
Is it possible to insert Ole Object runtime using crystal report 2008? If yes how and if not is there alternative to perform this job.
Please let me know your feedback.
Thanks

CrxDDrt.dll is only provided in order for the Crystal Reports designer in the .NET IDE.
1) You are not licensed to use this CraxDDrt.dll
2) Even if you were, in previous versions of CR, there were licensing implications to using the craxDDrt.dll (read $$)
3) Once your project would be done, using CR 2008, you would not be able to distribute the runtime as there is no CR MSM or MSI that contains the craxDDrt.dll and it's supporting runtime.
In your original post you say:
"I need to show Word and Pdf file in to Crystal report 2008 using CRAXDDRT.DLL";
I do not understand why you'd need to do this using the craxddrt.dll? You should be able to insert a BLOB field using the RAS SDK for .NET and CR 2008. Now, one hting you will have to keep in mind. If you insert a multipage .doc or .pdf file into the report, you will only get the first page of that document. I suggest you try this in the CR designer first. Always remember that if you can not do a certain thing in the designer, you will not be able to do it at runtime either. Giving all the limitations above, if you are still interested in doing this using RAS, let me know and I'll set you up with some resources to get you going.

Oracle 9 and Crystal Report

I want to run a crystal report against an oracle database procedure. I know that I will have to user REF CURSOR for that purpose. If I try to update a table within that procedure and use REF CURSOR and call the procedure from Crystal report it gives an error that you cannot update in this procedure. I just wonder if that is possible some how.
Basically I want to update a table after I run a Crystal Report but I can only call the crystal report from my application and do not want to run the update procedure seperately.
Thanks,

If the procedures work from SQL*Plus, then there can't be anything wrong with your databases. Also, Crystal should be able to run any procedure that will run from SQL*Plus, so that leaves the ODBC drivers to look at.
Look at the settings for the ODBC DSN. Is the stored procedure in the logged in user's schema, or in a different schema? The CR ODBC drivers default to looking only in the logged in user's schema. To use a stored procedure in someone else's schema, you must uncheck the "Use Current Schema for SQL Procedures" box.
If this is the case, be aware that when designing a new Crystal Report with that option unchecked, you may have to wait a very long time for the Database Expert to populate and display. Is there some reason that you can't use Crystal's native driver for Oracle. It does not have this problem.

Crystal Report with 2 oracle datasources (left outer join) very slow

I've made a crystal report with 2 oracle datasources (2 commands). I'm using crystal 10.
These 2 data sources are linked with a left outer join.
The report takes a while to run (more then one hour).
i can run Both query's in a couple of seconds/minutes, but it looks like crystal is runniing the second query for each record in the first query.
When i make the same report in BO. Just 2 queries with merged dimensions in the report, it is taking a couple of minutes to complete the report.
Question is if somebody knows how crystal is handling these 2 different data sources.
Is there any way to say to crystal to fetch the data of both queries and do the join after that?
At the moment it looks like that crystal is going to the other datasource for each record in the first query, which will cost a lot of time.

Joris,
I've always had a bad time combining a Command with any other object. Performance seems to drop dramatically, just as you've described.
I can't tell you specifically why, it falls off so bad...
The solution I've used is to do a linked server query (at least that's what it's called in MS SQL Server) I've never used Oracle, but I'd be VERY surprised if it didn't have that same feature. This will keep 100% of the processing on the server(s) and will get your run times back to what you would expect.
HTH,
Jason

How to get select query for crystal report in c# code

In C#, (Visual Studio 2008 ) I need to use the native Crystal Reports objects to get the complete SQL statement as it appears when you view it in Crystal Reports.
In Crystal Reports 12.0, Go to "Database > Show SQL Query..." ... That is what I need to get via C# code. I can get bits and pieces of parameter info etc but I just want the whole SQL statement.
How to get this?

Hi Ganesh,
It's simple to use RAS, include the assemblies and use this to open your report document:
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
using CrystalDecisions.ReportAppServer.ClientDoc;
using CrystalDecisions.ReportAppServer.Controllers;
using CrystalDecisions.ReportAppServer.ReportDefModel;
using CrystalDecisions.ReportAppServer.DataSetConversion;
using CrystalDecisions.ReportAppServer.DataDefModel;
        CrystalDecisions.CrystalReports.Engine.ReportDocument rpt = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
        ISCDReportClientDocument rptClientDoc;
To open the report use:
     object rptName = openFileDialog.FileName;
                rpt.Load(rptName.ToString());
                rptClientDoc = rpt.ReportClientDocument;
Then to get the SQL set the log on info:
            rptClientDoc.DatabaseController.LogonEx("10.50.212.77,1433", "xtreme", "sa", "password");
            GroupPath gp = new GroupPath();
            string tmp = String.Empty;
            rptClientDoc.RowsetController.GetSQLStatement(gp, out tmp);
            MessageBox.Show(tmp, "Data Source Set and SQL Statement", MessageBoxButtons.OK, MessageBoxIcon.Information);
Thank you

Step- by- Step on How to Load Excel data into Crystal Reports?

Hi Friends,
Can anyone send me a Step- by- Step on How to Load Excel data into Crystal Reports? Pls help me. Thanks in Advance.
Vijay

It's also important to 'prep' the excel file prior to connecting to it.
Give the data tab a meaningful name
Make sure the column headers are unique and that every column has a header
Delete any blank tabs
If you have trouble with Excel changing the data type of a field (say, a social security number you want to be a string value rather than a number so you don't lose leading zero) an alternative would be to save the spreadsheet file as a CSV, create a schema.ini to specify the data types for each column (example below) and use the same steps to connect except instead of choosing Excel 8.0, scroll to the bottom and choose Text. You have to make sure the CSV file is in the same folder as the schema.ini file that defines the columns.
Schema.ini example:
200912PUSD.csv
ColNameHeader=True
Format=CSVDelimited
MaxScanRows=25
CharacterSet=OEM
Col1=SSN Char Width 9
Col2=LAST_NM Char Width 25
Col3=FIRST_NM Char Width 25
Col4=DOB Date
Col5=STDNT_ID Char Width 10
Col6=SORTKEY Char Width 10
Col7=SCHOOL_NM Char Width 30
Col8=OTHER_ID Integer
Col9=GRADE Char Width 2
The filename in the first line needs to have the [] brackets around it, but I couldn't get it to display in this forum correctly.
