In the salesInvoice ssrs Report i have added a table called carTableEquipTmp which is not there by default, which I insert into along with the other tables(SalesinvoiceTmp and SalesinvoiceHeaderFooterTmp) in SalesInvoiceDP.InsertIntoSalesInvoiceTmp().
Even though my table carTableEquipTmp is getting successfully inserted into, the data doesn't show up on the report if i print a proforma report.
If i add test values to the carTableEquipTmp table in SalesInvoiceDP.processReport() they show up on the proforma invoice, but there's no way for me to get any parameters needed to set in the correct data into the table at this point. If i stop at this point in the debugger none of the data is present because processreport() is being called from a lower level in the code.
I think it might be a problem with maybe pack/unpack or that the proforma code runs from a server instance as the code run when it is proforma is quite different.
I can see that SalesInvoiceJournalPostBase.CreateReportData() creates an instance of salesInvoiceDP
salesInvoiceDP = new SalesInvoiceDP();
salesInvoiceDP.parmDataContract(salesInvoiceContract);
salesInvoiceDP.parmUserConnection(new UserConnection(true));
salesInvoiceDP.createData();
And that this might have something to do with it... but i still cant get the data i want in the carTableEquipTmp table.
So any idea on how to make Ax 2012 accept this new table i have added as it gets inserted into just like the other tables and there seems to be no problem...
I hope you guys can help.
The SalesInvoice report has two data classes you need to look at for the data provider, SalesInvoiceDP and SalesInvoiceDPBase. SalesInvoiceDPBase extends SrsReportDataProviderPreProcess, so there are a couple extra steps you need to take in order to add new datasources to the report.
In the salesInvoiceDP class, there is a method called useExistingReportData(), which re-inserts the pro-forma temp table data under a user connection, so the SrsReportDataProviderPreProcess framework will pick it up in your report. When the pro-forma process creates the report data, it doesn't insert with a user connection so it doesn't get added to the report. This method only gets called when the report is being run pro-forma.
You will need to add your temp table to this method, and follow the pattern for the other tables, so your code will look something like this:
//this is different from the buffer you insert your data with
CarTableEquipTmp localCarTableEquipTmp;
...
recordList = new RecordSortedList(tableNum(carTableEquipTmp));
recordList.sortOrder(fieldNum(carTableEquipTmp, RecId));
//You will need to add a field to relate your temp table
//to the current invoice journal, and insert it in
//InsertIntoSalesInvoiceTmp() if thats where you're inserting your table.
while select localCarTableEquipTmp
where localCarTableEquipTmp.JournalRecId == jourRecId
{
recordList.ins(localCarTableEquipTmp);
}
delete_from localCarTableEquipTmp
where localCarTableEquipTmp.JournalRecId == jourRecId;
recordList.insertDatabase(this.parmUserConnection());
This method re-inserts your data under the framework and deletes the original data. The data that was re-inserted will then get picked up by the framework and show in your report. If you open CarTableEquipTmp in the table browser, you will most likely see data still there from all the times you have tried running the report. This is why we have the delete_from operation after we re-insert the data. When data is inserted under a userConnection, it is automatically deleted when the report is finished
The other method you will want to modify is SalesInvoiceDP.setTableConnections(), and you will just need to add the following line:
CarTableEquipTmp.setConnection(this.parmUserConnection());
This will set the user connection for your table when running regular (not pro-forma). You will probably want to delete the data that is stored currently in your temp table using alt+F9 from the table browser.
Other than that it's all standard RDP stuff, but it sounds like you have that part working fine. Your temp table must be of type "Regular" for this to work.

I have created sales master and sales detail (master/detail) relationship form.
I have entered record and saved it ...
Through another form, i hv updated few fields of sales_master table .. see below example
During data entry - Like ... Sal_OrdStatus = 'Open' and CashRcvd_Status='P'
Updating these fields through payment form Sal_OrdStatus = 'Closed' and CashRcvd_Status='R'
After this, when I am entering/execute those records where both fields are updated
then see below error even record is available in the database/table
frm-40301 query caused no records to be retrieved, re-enter
enter image description here
Please advise solution/ guideline
Thanks

Querying data block won't return anything if there are no rows in the table at all, or if condition you set prevents any rows to be retrieved.
As some rows obviously exist (you updated them, not deleted), then it is the latter.
Use get_block_property built in and its last_query property (you can try default_where as well) to see which query was really executed; you'll see the where clause, and that should help you find the culprit. Once you know it, you'll be able to fix it.
is there a way to rollback a specific change. I have a button that creates a row in two different tables. I want the changes in one of the tables to be rolled back before the committing so that only the second table is committed. How would this be done? Running normal rollback rollbacks both table iterators.
Ive been trying different methods and nothing is working, Please help before I go insane.
find out the corresponding 'VO' row which you want to rollback .
#1. row.setNewRowState(Row.STATUS_INITIALIZED) ;
or
#2. row.revertRow() ;
or
#3. row.remove() ;
The closest thing to rolling back a row would probably be calling refresh on the view row with the appropriate parameters, something like this:
//Obtain app module
DCBindingContainer dcb = (DCBindingContainer) BindingContext.getCurrent().getBindingsEntry();
ApplicationModuleImpl am = (ApplicationModuleImpl) dcb.getDataControl().getDataProvider();
//Get your view
ViewObjectImpl vo = am.getMyView1;
ViewRowImpl row = vo.getCurrentRow(); //alternately use vo.findByKey to lookup a row or simply iterate through every row if dataset is sufficiently small
//rollback the row
row.refresh(Row.REFRESH_REMOVE_NEW_ROWS | Row.REFRESH_UNDO_CHANGES | Row.REFRESH_CONTAINEES);//review modes for ideal combination for use case
Note that rather than a refresh, a row.remove() would probably be sufficient for what it sounds like you are trying to do. In any case, you will need to keep track of the rows you do not want to commit.
While this solution would work, it does not sound ideal for your use case. If you never commit data in the other table, there is no reason to link it to a database table. I would probably do something like one of the following instead:
If the fields are the same in both tables (or similar) and it will be an all-at-once action, create a transient attribute on the ADF view object to denote whether or not the row is approved. Use view criteria on different instances of the view object (add to your application module twice) to display/process the rows you want. Remove not approved rows prior to committing.
If the fields needed are too different or you want to be able to handle one row at a time, make you history view object a programmatic view object with transient attributes, rather than basing it on the table/Entity. When a row is approved remove it from your history view and add it to your approved view.
Let's imagine we have a web-page with the content and one of the elements is table where we have couple of columns. It is done with Joomla, so basically I am working with the web-page constructor if I can call it like this and not with code. In the last column I have a link with query parameters, so something like this: link?qparam1=sth1&qparam2=sth. The values for these query parameters should be taken from the first and second column and inserted in this link. Otherwise I need manually to copy those values to each and every link which makes in very slow and inefficient especially when table values are changed, the link must be updated as well.
Is it possible to fetch the data from columns and include into the link?
Write a system plugin, Get data from a table, insert/update data to request
$app = JFactory::getApplication();
$app->input->set('qparam1','<value from table>');
it will update request data.
Im working on an online store project where I have already made it possible for an administrator to update different table entries via the store gui (like items, user profiles, orders etc). SaveChanges(); is used to save the changes.
Im currently trying to figure out how to make this work:
An entry in table "items" gets updated.
Before the entry in the table "items" gets updated, a copy of the old entry gets saved into a table named "history-items".
The copy that is saved to "history-items" preferably has a timestamp.
How would I go about doing this? (As you might tell, I just recently picked up visual studio, and am pretty new to everything)
Thank you.
There are atleast 3 ways to do this:
If you are using SQL Server 2008 or newer this is now built in functionality, see: http://msdn.microsoft.com/en-us/library/bb933994.aspx
If you opt not to use that then the simplest solution is to use database triggers.
If you want to do it in C# code, then you need to read the original values before saving, and save these original values to the history table. For reading original values see: How to get original values of an entity in Entity Framework?
I would go for option 1 if possible.
Basically, I have a LINQ database context and its model. As usually, I create the DB in the SQL context if the DB does not exist (the context is a singleton and on every access to it, this is checked).
Everything works well if I add data to the DB on the first launch. But if I don't insert any data during the first start of the app, on successive launches I get
SqlCeException:The specified table does not exist [TableName]
I don't know how more specifically I can explain it, but the exception comes immediately whenever I do a LINQ query on the second launch of the app if I don't insert any data on the first launch. If i do insert some data during the first launch, all is fine for the rest of the app's life time. Why would it be a bad thing to create the DBs and introduce the DB context, but not insert any data?
Here's my LINQ DB model:
https://github.com/kypeli/Podcatcher/blob/master/wp7/Podcatcher/ViewModels/PodcastSubscriptionModel.cs
Here's where I get the exception on second start if I didn't insert any data on the first launch:
https://github.com/kypeli/Podcatcher/blob/master/wp7/Podcatcher/PodcastSqlModel.cs#L64
It also strikes me that there's no API call to check if a table exists or not in LINQ, so I would have to assume "this should just work" - but it doesn't.
Any ideas? Thanks! :)
Update: I verified analyzing the .sdf file that indeed there are no tables created if I don't insert any data upon first launch of the app. As I see it:
This is a bug in LINQ-to-SQL. It should not crash if there are no tables present, but know that it should create them. Or deal with the case and create tables only when data is inserted.
I would need to insert some dummy data into SQL always on first launch, or...
Check if a table exists, if not, react to it by forcing LINQ-to-SQL to create them. But how?
I've dealt with this problem also, I've fixed it this way:
get the data context:
dbDataContext = new DBDataContext(DBConnectionString);
if( dbDataContext.DatabaseExists() == true)
//then try to get an entity:
System.Data.Linq.Table<Entity> entities = dbDataContext.Tablename;
//try to get an element from the entity:
IEnumerator<Entity> enumEntity = entities.GetEnumerator();
entities.GetEnumerator(); will always raise the exception "Table not found."
Just use a try/catch and in the catch scope delete the db and recreate it, because your DB is empty anyway :)
dbDataContext.DeleteDatabase();
dbDataContext.CreateDatabase();
dbDataContext.SubmitChanges();
