According to the Peoplebook here, CreateRowset function has the parameters {FIELD.fieldname, RECORD.recname} which is used to specify the related display record.
I had tried to use it like the following (just for example):
&rs1 = CreateRowset(Record.User, Field.UserId, Record.UserName);
&rs1.Fill();
For &k = 1 To &rs1.ActiveRowCount
MessageBox(0, "", 999999, 99999, &rs1(&k).UserName.Name.Value);
End-for;
(Record.User contains only UserId(key), Password.
Record.UserName contains UserId(key), Name.)
I cannot get the Value of UserName.Name, do I misunderstand the usage of this parameter?
Fill is the problem. From the doco:
Note: Fill reads only the primary database record. It does not read
any related records, nor any subordinate rowset records.
Having said that, it is the only way I know to bulk-populate a standalone rowset from the database, so I can't easily see a use for the field in the rowset.
Simplest solution is just to create a view, but that gets old very soon if you have to do it a lot. Alternative is to just loop through the rowset yourself loading the related fields. Something like:
For &k = 1 To &rs1.ActiveRowCount
&rs1(&k).UserName.UserId.value = &rs1(&k).User.UserId.value;
&rs1(&k).UserName.SelectByKey();
End-for;

Looks like a silly question, but I can't find a way to access the DataViews in my DataViewManager.
I can see it in the DataViewManager Visualizer window, so there must be a way.
What am I doing wrong?
dvm = New DataViewManager(MyDS) ''-- MyDS is a strongly typed dataset
dvm.CreateDataView(MyDS.Company)
dvm.CreateDataView(MyDS.Sites)
MsgBox(dvm.DataViewSettings.Count) ''-- shows 7, even though I added only 2.
For Each view As DataView In dvm ''-- Error!
MsgBox(view.Table.TableName)
Next
I also observed that irrespective of how many DataViews I create, data the DataViewManager Visualizer shows all DataViews in my dataset. Why?
how do I hide those rows in parent whose child data view returns 0 rows after applying RowFilter on child
I've done it like this, but it feels like a nasty hack; I've never read the source deeply enough to know if there is a better way:
Add a column to your child datatable: Name: IsShowing, Type: Int, Expression: 1, ReadOnly: True
Put the following code:
ChildBindingSource.RemoveFilter()
ParentBindingSource.RemoveFilter()
YourDataSet.ChildDataTable.IsShowingColumn.Expression = ""
YourDataSet.ChildDataTable.Expression = $"IIF([SomeColumn] Like '{SomeFilterText}',1,0)"
ChildBindingSource.Filter = "[IsShowing] > 0"
ParentBindingSource.Filter = "Sum(Child.IsShowing) > 0"
The removal and re-add triggers a re-evaluation of the expression and the filters. There is probably a way to do this without removing/re-adding but I haven't yet found it.. Expressions are normally only re-evaluated when row data changes; changing an expression doesn't seem to recalculate all the row values/trigger a refresh of the relations and BS filters
It would be great if the parent filter supported complex expressions like SUM(IIF(Child.SomeColumn = 'SomeFilter',1,0)>0 but the SUM operator expects only a column name in the parent or child. As such, the circuitous route of having a column with an Expression be the part inside the SUM is the only way i've found to leverage the built in filtering
Remember when you test that the search is case sensitive. If you want it not to be you might have to have another column of data that is the lowercase version of what you want to search and lowercase your query string
I'm triying to retrieve a ClassDescription symbolicName of an IDocument object. It seems that i have to fetch its ClassDescription even if I just want the symbolicName.
Is there a way to do it ? I just want to avoid doing a fetch for every browsed document...
(Also IDocument.GetClassName doesn't help, it returns "Document")
I finally found a way, by making an SQL SELECT request retrieving the classDescription ID (which is not the symbolicName ID, but rather an "internal" one) :
Select This, d.Id, d.ClassDescription
From Document d
where d.Id = ID
It seems to be lighter than a line like document.fetch(classDescription) (pseudo call) cause it should just retrieves the ID.
I thought it worth mentioning a problem regarding the accepted answer.
There are times that doing a query would be "lighter" however I believe you are missing something involving fetching a document.
FileNet's fetchInstance command can take in a PropertyFilter.
In your case you could do something along the lines of:
PropertyFilter pf = new PropertyFilter();
pf.AddIncludeProperty(new FilterElement(null, null, null, "ClassDescription", null));
doc = Factory.Document.FetchInstance(os, new Id("doc.ID()"), pf);
You would probably want to look at your original fetch of this document and make sure to specify the full list of property filters at that point.

I am missing the SQL out of this to Bulk update attributes by SKU/UPC.
Running EE1.10 FYI
I have all the rest of the code working but I"m not sure the who/what/why of
actually updating our attributes, and haven't been able to find them, my logic
is
Open a CSV and grab all skus and associated attrib into a 2d array
Parse the SKU into an entity_id
Take the entity_id and the attribute and run updates until finished
Take the rest of the day of since its Friday
Here's my (almost finished) code, I would GREATLY appreciate some help.
/**
* FUNCTION: updateAttrib
*
* REQS: $db_magento
* Session resource
*
* REQS: entity_id
* Product entity value
*
* REQS: $attrib
* Attribute to alter
*
*/
See my response for working production code. Hope this helps someone in the Magento community.
While this may technically work, the code you have written is just about the last way you should do this.
In Magento, you really should be using the models provided by the code and not write database queries on your own.
In your case, if you need to update attributes for 1 or many products, there is a way for you to do that very quickly (and pretty safely).
If you look in: /app/code/core/Mage/Adminhtml/controllers/Catalog/Product/Action/AttributeController.php you will find that this controller is dedicated to updating multiple products quickly.
If you look in the saveAction() function you will find the following line of code:
Mage::getSingleton('catalog/product_action')
->updateAttributes($this->_getHelper()->getProductIds(), $attributesData, $storeId);
This code is responsible for updating all the product IDs you want, only the changed attributes for any single store at a time.
The first parameter is basically an array of Product IDs. If you only want to update a single product, just put it in an array.
The second parameter is an array that contains the attributes you want to update for the given products. For example if you wanted to update price to $10 and weight to 5, you would pass the following array:
array('price' => 10.00, 'weight' => 5)
Then finally, the third and final attribute is the store ID you want these updates to happen to. Most likely this number will either be 1 or 0.
I would play around with this function call and use this instead of writing and maintaining your own database queries.
General Update Query will be like:
UPDATE
catalog_product_entity_[backend_type] cpex
SET
cpex.value = ?
WHERE cpex.attribute_id = ?
AND cpex.entity_id = ?
In order to find the [backend_type] associated with the attribute:
SELECT
backend_type
FROM
eav_attribute
WHERE entity_type_id =
(SELECT
entity_type_id
FROM
eav_entity_type
WHERE entity_type_code = 'catalog_product')
AND attribute_id = ?

I'm trying to generate a new SharePoint list item directly using SQL server. What's stopping me is damn tp_DirName column. I have no ideas how to create this value.
Just for instance, I have selected all tasks from AllUserData, and there are possible values for the column: 'MySite/Lists/Task', 'Lists/Task' and even 'MySite/Lists/List2'.
MySite is the FullUrl value from Webs table. I can obtain it. But what about 'Lists/Task' and '/Lists/List2'? Where they are stored?
If try to avoid SQL context, I can formulate it the following way: what is the object, that has such attribute as '/Lists/List2'? Where can I set it up in GUI?
Just a FYI. It is VERY not supported to try and write directly to SharePoint's SQL Tables. You should really try and write something that utilizes the SharePoint Object Model. Writing to the SharePoint database directly mean Microsoft will not support the environment.
I've discovered, that [AllDocs] table, in contrast to its title, contains information about "directories", that can be used to generate tp_DirName. At least, I've found "List2" and "Task" entries in [AllDocs].[tp_Leaf] column.
So the solution looks like this -- concatenate the following 2 components to get tp_DirName:
[Webs].[FullUrl] for the web, containing list, containing item.
[AllDocs].[tp_Leaf] for the list, containing item.
Concatenate the following 2 components to get tp_Leaf for an item:
(Item count in the list) + 1
'_.000'
Regards,
Well, my previous answer was not very useful, though it had a key to the magic. Now I have a really useful one.
Whatever they said, M$ is very liberal to the MOSS DB hackers. At least they provide the following documents:
http://msdn.microsoft.com/en-us/library/dd304112(PROT.13).aspx
http://msdn.microsoft.com/en-us/library/dd358577(v=PROT.13).aspx
Read? Then, you know that all folders are listed in the [AllDocs] table with '1' in the 'Type' column.
Now, let's look at 'tp_RootFolder' column in AllLists. It looks like a folder id, doesn't it? So, just SELECT the single row from the [AllDocs], where Id = tp_RootFolder and Type = 1. Then, concatenate DirName + LeafName, and you will know, what the 'tp_DirName' value for a newly generated item in the list should be. That looks like a solid rock solution.
Now about tp_LeafName for the new items. Before, I wrote that the answer is (Item count in the list) + 1 + '_.000', that corresponds to the following query:
DECLARE #itemscount int;
SELECT #itemscount = COUNT(*) FROM [dbo].[AllUserData] WHERE [tp_ListId] = '...my list id...';
INSERT INTO [AllUserData] (tp_LeafName, ...) VALUES(CAST(#itemscount + 1 AS NVARCHAR(255)) + '_.000', ...)
Thus, I have to say I'm not sure that it works always. For items - yes, but for docs... I'll inquire into the question. Leave a comment if you want to read a report.
Hehe, there is a stored procedure named proc_AddListItem. I was almost right. MS people do the same, but instead of (count + 1) they use just... tp_ID :)
Anyway, now I know THE SINGLE RIGHT answer: I have to call proc_AddListItem.
UPDATE: Don't forget to present the data from the [AllUserData] table as a new item in [AllDocs] (just insert id and leafname, see how SP does it itself).
I use jqGrid to display data which is retrieved using NHibernate. jqGrid does paging for me, I just tell NHibernate to get "count" rows starting from "n".
Also, I would like to highlight specific record. For example, in list of employees I'd like a specific employee (id) to be shown and pre-selected in table.
The problem is that this employee may be on non-current page. E.g. I display 20 rows from 0, but "highlighted" employee is #25 and is on second page.
It is possible to pass initial page to jqGrid, so, if I somehow use NHibernate to find what page the "highlighted" employee is on, it will just navigate to that page and then I'll use .setSelection(id) method of jqGrid.
So, the problem is narrowed down to this one: given specific search query like the one below, how do I tell NHibernate to calculate the page where the "highlighted" employee is?
A sample query (simplified):
var query = Session.CreateCriteria<T>();
foreach (var sr in request.SearchFields)
query = query.Add(Expression.Like(sr.Key, "%" + sr.Value + "%"));
query.SetFirstResult((request.Page - 1) * request.Rows)
query.SetMaxResults(request.Rows)
Here, I need to alter (calculate) request.Page so that it points to the page where request.SelectedId is.
Also, one interesting thing is, if sort order is not defined, will I get the same results when I run the search query twice? I'd say that SQL Server may optimize query because order is not defined... in which case I'll only get predictable result if I pull ALL query data once, and then will programmatically in C# slice the specified portion of query results - so that no second query occur. But it will be much slower, of course.
Or, is there another way?
Pretty sure you'd have to figure out the page with another query. This would surely require you to define the column to order by. You'll need to get the order by and restriction working together to count the rows before that particular id. Once you have the number of rows before your id, you can figure what page you need to select and perform the usual paging query.
OK, so currently I do this:
var iquery = GetPagedCriteria<T>(request, true)
.SetProjection(Projections.Property("Id"));
var ids = iquery.List<Guid>();
var index = ids.IndexOf(new Guid(request.SelectedId));
if (index >= 0)
request.Page = index / request.Rows + 1;
and in jqGrid setup options
url: "${Url.Href<MyController>(c => c.JsonIndex(null))}?_SelectedId=${Id}",
// remove _SelectedId from url once loaded because we only need to find its page once
gridComplete: function() {
$("#grid").setGridParam({url: "${Url.Href<MyController>(c => c.JsonIndex(null))}"});
},
loadComplete: function() {
$("#grid").setSelection("${Id}");
}
That is, in request I lookup for index of id and set page if found (jqGrid even understands to display the appropriate page number in the pager because I return the page number to in in json data). In grid setup, I setup url to include the lookup id first, but after grid is loaded I remove it from url so that prev/next buttons work. However I always try to highlight the selected id in the grid.
And of course I always use sorting or the method won't work.
One problem still exists is that I pull all ids from db which is a bit of performance hit. If someone can tell how to find index of the id in the filtered/sorted query I'd accept the answer (since that's the real problem); if no then I'll accept my own answer ;-)
UPDATE: hm, if I sort by id initially I'll be able to use the technique like "SELECT COUNT(*) ... WHERE id < selectedid". This will eliminate the "pull ids" problem... but I'd like to sort by name initially, anyway.
UPDATE: after implemented, I've found a neat side-effect of this technique... when sorting, the active/selected item is preserved ;-) This works if _SelectedId is reset only when page is changed, not when grid is loaded.
UPDATE: here's sources that include the above technique: http://sprokhorenko.blogspot.com/2010/01/jqgrid-mvc-new-version-sources.html
