Actually I am wondering how can we use Other Data manipulation statements like INSERT and UPDATE statements inside iReport designer. I have been searching the solution for very long time but could not find anything which can actually help me.
I know even in Ireport I cant use multiple select statements separated with " ; ".
Is it possible to use these statements in Ireport?
IReport is for report creation only. If it can execute insert or update to database then its no longer for report. A report is something that presents meaningful data based on the user requirements. Whatever data you pass them, it can only format it, add some cosmetics, then make it printable. If you need something that inserts or updates data to the database, IReport is not what you want, but a software itself.

I am currently using crystal reports to create a price list which MUST have a table of contents. The report is passed a dataset from a stored procedure, though I don't think anything I can do server-side will be able to achieve this.
What my question is really is, is there any way of finding what page a particular value in a group header is on, if I can do this I can obviously create an index page with dynamic page numbers easily.
I used to create crystal reports by going into database expert, selecting tables and specifying the link manually. As I get a bit more comfortable with CR, there is a need for me to put the underlying SQL query into a store procedure to provide data to the report. But doing so will require me to rewrite the whole report which is time consuming.
So, my question is if there are any guru in the community that could and/or have tried to replace the underlying SQL (created by manually add table and links) with a store procedure or cmd without having to rewrite the whole report? I would love to get some hint of how to do that as I have a couple dozen of reports that need "adjustments" and time does not permit me to rewrite them all.
My Crystal Report versions are CR 2008 and CR 2012.
Thank you in advance.
In case you can use an existing software : this feature is available in a free Crystal reports viewer. Here is the documentation, which explains the use :

Crystal does an absolutely horrible job of migrating from many tables to a single DB object, be it a Command or stored procedure.
You might be able to Database | Set datasource location... to map your SP to one of the many tables in the report (choose the one that has the most fields in use); I've never been able to get this feature to work trying to map a Command to a table.
'Best practice' for a really-poor 'feature' set:
create a formula field for each field that will be on the canvas, but isn't grouped (these fields won't be removed when you change datasources)
add the Command to the report; link tables if desired
manually switch grouping, record-selection formula, sorting, etc.
We are generating reports based on iReports and JasperReports for web application.
Using iReports I found I am struck with big problem.
I want to use two SQL query to fill up my main report...
In query designer I can only write one query..
For another query I cannot use sub-reports...
How do I write second query which will return different fields and include them in my report..
Please guide...
I cannot use sub-reports...
Yes, adding a table to your report is as easy as adding a field. Just drag it from the palette and drop it in the report where you need to have it.
Add a new Table data source. I assume this was done.
Once the data source is configured, you could design your table UI using the wizard.
just click on next or finish to close the wizard.
To add a parameter in data set (if needed), Navigate to your data set using the report inspector. Expand your data set. You would find the parameters menu. Right click to add the new parameter.
Now right click on your table and select edit table data source. Here you will find options to pass parameters to your table from the main report. Passing parameters to your table should be as simple as you do in sub reports. Select the parameter just created from the drop down list box and pass the required value.
In the Data set run Dialog box that appears, please make sure of the data set and the report connection you are using.
You are done configuring the table with this, next you will place the fields in the cells of table for displaying the data.
You are getting your document has no pages since the main report query does not return any rows i guess. For your table to be executed your main report must return at least a row
Hope this helps you.
Good Luck!!
As far as Ireports are concerned, the main report can comprise only one query. And if you wanna use multiple queries in your report, it is possible in the following ways.
Sub Report
Table Dataset.
sub Dataset.
since you don wish to use a sub report, you can go for a Table Dataset. Anything you would do with a sub report is possible with table dataset too(Except for returning variables). You can use sub datasets with charts and graphs. Table set will be of use to you i hope.
Issue
I have a report in CR 2008 that I inherited from someone else
A sub-report in the report pulls its data from a database view
A field exists, "TRANSCBFLAG" in the view -- it's a string with values of "Y", "N", or "D"
The view has these values
The report displays every other value, but not this one field.
Attempted Resolutions
Suppression attribute? -- No, it's unchecked
Field type issue? -- No, it's a string
Font and background? -- No, it's black font / white background
Suppression / formatting formulas? -- no formulas on display or suppression in subreports or report
Space constraints? -- stretched the field out below all other fields -- still shows as blank
Check to make sure Crystal can see the data -- right-clicked field, select "Browse Field Data", and it came back with the three potential values. So, it can see them in the DB at least, and potentially even in the fields itself.
Just a local Crystal Issue? -- No; I uploaded the report to Business Objects XI for a test and all fields still display except that one.
Question
Where in the process could I be going wrong? It shows when I run the view directly from the database, and every other field shows perfectly in Crystal the first time.
I would assume you did 'Verify Database' but if not that's the first thing I would have tried.
And just a piece of advice... always, always, always run your reports off of a command you write yourself instead of using Crystal's GUI to let you select tables/views/procs. This allows you to make pretty much any kind of change to the query you want and even completely change the source from where your data is coming without wiping all your report controls away. If the modified query has the same field names it will always work seemlessly and if not it will give you a chance to redirect which fields are supposed to come from where. Otherwise... you will have to recreate everything as you just experienced.
There may be a more correct answer, but in a pinch, removing the view from my report (thus removing all fields), adding the view again, and redoing all fields caused the field to display correctly. Not sure how or why.
A further explanation would be appreciated, but for now, that's all I've got.
I had the same issue on a new report I'd created and finally found that the issue was in one of the parameters I used in my command SQL - it had double }} at the end. Eliminating one of the }s allowed the query to return data.
That said, go over the SQL in your database expert with a fine toothed comb, and you'll likely find the issue!
I have some big reports. What I need is the list of 'displayed' column names - not the actual fields(that I know how to get). Is there a way to get that info programmatically? I need to get them so end user can decide what columns can be deleted. I am using crystal report 8.5.
Thanks
This might be worth a shot. First, export the report's definition ('File' -> 'Export' -> 'Export Report' -> 'Format': Report Definition). That should kick out a text file with quite a bit of information about the report, including all the data fields referenced. You could write a simple script to parse the file and spit out all of these fields.
I've never tried this before, so your mileage may vary. One thing to think about is what you mean by "displayed" fields. Fields could not be directly displayed on the report, but be used to calculate formulas or summaries which are displayed. You'll need to think about this along with how your specific reports are written when writing your script.
