Change licensing mode

Hello

Can someone tell me which is the quickest method to change the licensing mode after RS has been installed (per seat -> per processor)

Many thanks!

Worf

Well apparently you can't. The only way you can is by reinstalling RS.

change authentication method in a local database file

I have made a small asp.net project which uses a local database file as a part of the project. The project is running fine om my local machine, but when I upload it to the remote server, the login fails for the server.

I suspect this is can be solved by using sqlserver authentication. But I have now spent a lot of time trying to configure the database file to use this authentication mode. As I see it there are three possible solutions to the problem.

use management studio express to configure the local mdf file (Ecxept that I cant find out how to connect to the mdf-file) and from here change the authentication method to sqlserver authentication. use Visual Web developer to change the authentication method (but how?) make the windows authentication work on the server (this would probably require that mannamgement studio express connects to the remote database. (Same problem as no 1)

Help will be higly appreciated.

hi Bjarke,

to make things run, the account running the application server must be one of the SQL Server registered logins (at the instance level and not database level).. if your solution is hosted, I do think the IT stuff of the hosting company provides that "by default" or nothing would run, and I do not think they will grant you a standard SQL Server login... did you contact them?

Hello Andrea!

Maybe I have misunderstood something?

When you make an asp.net 2.0 project there is a folder (App_Data) where sit is possible via Visual web developer to add a sql database file. As I have understood it this file works as a little database server as well. Does SQL server even have to be installed on the server to make these files work as a database?

I have not contacted the hosting company about this problem, because I didnt consider it a problem. But Maybe I am wrong.

Do you know how to change the autnentication method for a local database file? I have tried a lot of things, and searched the internet for an answer, but without luck.

Thanks Bjarke

perhaps you are intending User Istances "mode", a feature available only with SQLExpress edition of SQL Server 2005.. remember that this feature is not provided by hoster that do not have SQLExpress but "traditional" SQL Server 2005 editions...

Does SQL server even have to be installed on the server to make these files work as a database?

yes, SQLExpress must be installed on the computer running the application, in your case the web application, thus the application server... when the app start's up, a User Instance of SQLExpress is generated (if not already existing)...

Thanks Bjarke

the "traditional" authentication "setting" can be changed using SSMSE, accessing the instance property, in the security tab or modifying a Windows registry key.. stay with the first one

the service must be restarted to use the new settings..

as regard user instances, only Windows authentication can be used with this "access mode"...

if you mean how to modify the authentication settings in the connection strings, you can have a look here..

Change "Output Alias" on synchronous component programatically

Wanted to enquire how this is done. Tried doing it in the setUsageType method I have overwritten but only allows description to be changed. Basically need to change "Name".

Best option would be to change it instantly when a user selects a column from the inputs in the custom component, ie. it changes the Output Alias to a desired value. (Input tab in advanced editor)

All this is being done in a custom component which I would like to be synchronous, can achieve a similar result asynchronously.

Thanks

Not relaly sure if this can be done, as there is no output column, just the upstream input column which has already been named. If you select the column, then can you not change the IDTSInputColumn90 name in SetUsageType? What happens? The other thing to try would be to change the name property on the IDTSVirtualInputColumn90, can you?

You do not really have an output alias. When you see this in the stock UIs it is because you are creating a new output column, which is not what you appear to be doing.

|||

If you change the name is setUsageType you see a change in debug mode but eventually it does not change the column name (strangely description can be changed however), basically change is ignored. When I change the Output Alias in the gui advanced designer (non programatically) it does not create a new output column in the output column tab listing but does successfully change the alias and column name, which is basically the result I want. Have been able to achieve the change with a new output column and asynchronous component but wanted to do it synchronously. Also figured it could be done programatically due to the fact you can do it non-programatically in the gui advanced editor.

Thanks, will try the virtual column thing.

Celko nested sets vs. linked tables

Hi,

I am trying to revamp our product database with a view to making it search-optmised and would like some guidance (or confirmation of method, if you will!!). We currently use a three table structure (Product, Brand, Cat(egory)) along the lines of :

create table product
(prod_id int not null,
brand_id int not null,
cat_id int not null,
other stuff e.g. tech. specs, displayed text on web page, etc...
)

with corresponding brand_id and cat_id in the other tables. While this seems relationally sound I see it as being inefficient for searching, particularly after reading the theory behind nested sets.

A new function I am building will enable users to drill down through the product list or runs searches against all or part of the db :

e.g. all products from one category,
all products fitting certain search criteria,
products from several selected brands fitting certain criteria,
and any combination of the above you can think of!

The problem is, not all products have the same criteria list (in fact I would be surprised if any did) and may also be of more than one category (a digital camera with movie mode might easily fit into the digital camcorder search). I think I am correct in that a nested set would make the structure fit the requirement - things like criteria, displayable text, etc. could be nodes in their own right and each logical level might have its own criteria. For example, if a category is selected then certain text must be displayed and could list further categories or products. The next level down would then require its own displayable text - I am mainly thinking about SEO tags here. Also, I am not precious about retaining the current table structure and would like an open ended solution where I can add further data/functionality in a dynamic fashion, which nested sets seem to embody.

Does this make sense to anybody coz I think I've confused myself even more!!

Thanks in advance,

Gok...a collective ...huh?|||Originally posted by hoyleg

The slightly more complicated problem is how to enable search by brand - if product is the last node in the tree (say) and brand is specific to product then a query to determine which categories to display given a specific brand becomes quite hairy. I guess I'm trying to combine two ways of looking at my data - bottom-up and top-down in one method.|||definitely if category belongs to brand then it's bottom up

and what do you do if a category at a higher level belongs to a different brand than categories at lower levels in its subtree?|||Originally posted by hoyleg

Exactly...Bottom Up...And it sounds like the data is fairly static no?

It's like code tables...

Have a nightl process to rebuild to data. Have the element column 1, column 2 the level, column 3 the lineage of the data...then you'll have it all in one reference...

you can even have the grandady of all in one seoarate column...

granted this will take iterations and a cursor, but it'll be done overinight...

here's another: Multi-Threaded Message Board Solution -- Hierarchical Data without the Adjacency Model (http://morgankelsey.com/code/multi-threaded_board/)|||Very cool...but rank is already associated with the data...without it, won't it be a problem?|||May be a tad out of my depth here, so feel free to give me change for my .02 USD.

I don't see rank as having anything to do with the data. The data could be ordered in any number of ways (price, number of buttons, shininess of casing material, etc.). Because of that, I am not sure a Hierarchical model is going to be so good for the problem at hand. Would it be better to just have a mapping table between the category table and the product table, so you can have different products be members of multiple different categories (as in the digital camcorder example above)?

Not too sure how you mean drill down. Do you mean from category to product? Or are the products grouped in other ways?|||Originally posted by MCrowley

No I think you're correct...it's just that I still don't understand...

What's the goal here?|||ah! a collective ... d'oh!

some good input here - I'm just applying my model to those suggested to work out which is best. my brain really hurts!

I'll try and fill in a few gaps too -

Yes, the data could simply be described in a couple of look-ups but I'm trying to optimise for selects. It might not be a problem initially but when I'm fielding 100k+ records against ~100 brands and ~100 categories (some with subcats) I am worried response times will be poor, especially when I'm specifiying lots of 'where' clauses on top of two joins (+ non-dedicated server). What initially attracted me to nested sets was the fact that because you already know the first and last id for every child/grandchild of a node a select is a one-liner and wheres can be piled on afterward without much worry.

That and the products do appear to be grouped in two ways - by category and by brand. I see category as being the most important as users are more likely to be comparing products of the same type, which would mean brand could then simply be a criteria to search under. OK, I think that's one question answered!

To recap I see a table (nested set) of categories (an example traversal would be: Digital Products -> DVD Equipment -> DVD Recorders -> Products, another: Digital Products -> Digital Cameras -> Products). Everything on a last node is then a product, all others are category and will be used for most display purposes (breadcrumb trails, etc.). Every category/subcategory/product would have displayed text as additional fields (h1, h2, meta tags, etc.) and only product would have manufacturer as an ID against a second, look-up table (to avoid any major data redundancy). Given this setup, where are criteria lists best placed? This would essentially be a list of tech. features a user could specify to narrow their search down a bit and would change with every category/subcategory/product.

Have a look at www.dealtime.co.uk as a nice indication of where I am trying to go with this, only with an additional emphasis on a really powerful search facility to complement. Drill down through the categories and have a look what pops out - products and subcats on the same page, etc. I don't suppose anybody reading this designed this site?? No? Bugger...|||Brett's link to SQLteam.com is informative, but I think their opinions are a little out of date. I've found it easy to navigate adjacency models now that table functions have been implements in SQL Server 2000. Here is a skeleton table function that returns all the progeny for a parent ID, plus their nesting level:

-------------------
create function GetChildren(@.ParentID as int)
returns @.OutputTable Table (ParentID int, ChildID int, NestLevel int)
as

begin
--First ensure the specified ID exists in the table
insert into @.OutputTable (ChildID, NestLevel) select RecordID, 0 from RecordTable where RecordID = @.ParentID

--Then iterate until done
while @.@.RowCount > 0
insert into @.OutputTable (ParentID, ChildID, NestLevel)
select RecordTable.ParentID, RecordTable.RecordID, OutputTable.NestLevel + 1
from RecordTable
inner join @.OutputTable OutputTable on RecordTable.ParentID = OutputTable.RecordID
where not exists(select * from @.OutputTable CurrentIDs where CurrentIDs.ParentID = RecordTable.ParentID and CurrentIDs.ChildID = RecordTable.RecordID)
return
end

------------
I've joined this type of function into statements in procedures many times, and it has always worked effectively.

I've never implemented the Nested Set model. It looks like it might be interesting to play around with, but I've had a hard enough time explaining the adjancency model to beginning-to-midlevel dbas. I don't know that you could ever count on finding a designer to support the nested set model.|||No...but this guy...

http://www.sqlteam.com/forums/pop_profile.asp?mode=display&id=100

Maintains this one...

http://www.sqlteam.com/default.asp

And blindamn may be correct, however it is definetly not set based like Rob is trying to suggest.

Also, YUKON will have this functionality built in...don't know what it's called, but the recursive query paramaters in Oracle are called by using CONNECT BY...

How often is the (category) data updated? Isn't this like an admin function?|||hehe my developer will support nested sets if I tell him to ;)

There's only myself and one other guy to worry about (at the mo!) and by docs/comments I hope to make the code operation obvious.

And yes, the data is largely static and admin functions will handle updates but they don't have to be the slickest code possible - it's just viewer performance I am worried about.|||That's why I guess I'm hinting at a Noramalized set of data for transactional purposes and then a "viewer" set of denormalized data that get's built nightly...|||Ahh, I think I am beginning to see. I would lean toward the nested set only oon the categories table, then the leaf nodes of the categories are mapped to products in a standard mapping table. Yes, you would have a 100k+ map table joined to a 100k+ products table, but the indexes *should* be able to take care of that problem.

But this assumes that the only reason you want the full hierarchy is to display the breadcrumbs on the top of the page? No, you might want to search on a leaf node category right off from the get-go. But that is just as easy with a cat_id, name, parent_id scheme...Maybe I should just let this thread pass by...

I must be missing something here. Just can't tell what it is. What part of the searching is it that concerns you the most?|||The main advantages i can see by using sets would be the lightweight query for page content and link generation (and the extra info would be for all SEO data aswell as breadcrumbs e.g.page title, metas, header tags), nice clean selects (inserts and updates look ugly no matter what the implementation) and easily resizeable node depths (other methods all seem to use recursion which I'm trying to avoid).

The categories do seem ideal for this method and what worries me about the search is attaching search criteria for categories. I need generic criteria for categories (RRP, dimensions, power supply, etc.) and then add-on additional criteria for subcategories (screen size for tvs, zoom for cameras, etc.). As selecting from a set includes all progeny (love that word!) easier than not it again seems to fit the model.

Now I think about it, the bottom node could contain two table refs, one a table of criteria ids, again referencing a look-up of criteria details such as display name and the other a table of productids, each with a manufacturer id ... you can guess the rest. Thus I get no recursion (in select) and a nice clean generic browse along with a quick criteria lookup. Can't avoid the joins but they don't affect a huge chunk of record selection.

Thanks for all the input guys but I think that's it sortd (let me know if there's any glaring holes tho!!). Now I've just got to build the sodding thing.
