RAPI, CCeDBDatabase, EDB, CEDB, And The Future
Jan 15, 2006
Hi,
I'm trying to migrate to VS2005 and prepare for future Windows Mobile releases. My app uses MFC, CCeDBDatabase, and RAPI from the desktop to sync with the device version of the app. Works great now, but I'm worried about how many different ways it will be broken in the future .
My questions - first, are we pretty certain that CEDB will NOT be supported after WM5? Next, is there, or will there be, a CCeDBDatabase class for EDB? VS2005 seems to know nothing about CCeDBDatabase. What should I be doing with the CCeDBDatabase; do I need to re-write everything using only API calls? Also, there is no RAPI for EDB, is this correct? If so how can I switch to EDB and still communicate/sync with the desktop using RAPI? As always, any advice is greatly appreciated, thanks!

My PC app uses RAPI to install files to a CEDB database on Windows Mobile devices.
Works for PPC 2002, 2003 devices, ActiveSync v3.8 and 4.1
On Windows Mobile 5.0 devices with AS 4.1, RAPI fails on CeMountDBVol with an ERROR_INVALID_PARAMETER.
What needs to be done to correct this? I have read about RAPI Security policy, but this case doesn't seem to apply.
I am loading RAPI DLL dynamically.
ex:
bResult = (*pCeMountDBVol)(pDBguid, // guid of mount
DBVolumeFullName, // full path and name of database volume
OPEN_ALWAYS)); // flags
I didn't think that there were security restrictions when mounting your own database volumes.

I have a windows forms application that runs on my PC that populates a SQL Server Compact 2005 database and then transfers that .sdf file to my mobile device. The communication between the mobile device and PC is done using the Desktop RAPI class from OpenNetCF (http://www.opennetcf.com/FreeSoftware/DesktopCommunication/tabid/90/Default.aspx)
Anyway, I was previously using SQL Server Mobile 2005 and my populated .sdf was around 1.7 MB and I could transfer it to my mobile device in a minute. Once I switched to SQL Server Compact 2005, the transfer process began taking 3 minutes with a 1.5 MB .sdf file. The SSCE also got bloated more easily so I added in the Compact operation each time after I fully populate the SDF to keep the file size at 1.5 MB, but even then it still takes 3 minutes.
I've done a few tests where I simply switch between the two database versions and that simple switch of the version changes the transfer time. I am dumbfounded trying to figure out what the cause might be. Since it is just a file transfer, why would the version even matter unless somehow SSCE is really not compacting and lying about its actual size.
Has anyone run into anything similar to this or may have any ideas what might be going on?
Thanks.

Hi,
We have a NT service built via Visual Basic 6 which fires dts processes on demand according some criteria. Well, on the whole and basically only for the following rule:
-dts process is executed when our service recognize a concrete plain file leaved in a folder. It€™s generally generated for a mainframe JCL along with a activator file (.nul file, empty). Each application own a folder and each folder have lots of files as the aforementioned ones. Scheduler for that is an ASP application that lives within a intranet. It also is a monitor and logger
In that schema, keeping on mind that eight out of ten are ETL processes, critical ones and on daily-basis, our question is, how to handle on with this stuff using by sql25k and its powerful SSIS?? Migrating such dts packages to SSIS packages is a piece of cake (now no before; thanks Jamie, Michael and other guys for your awesome help) because of its tipology. However our main concern is what the hell to use. Centralized dtsx package running all day long as a service, listening and checking for files? .Net windows application either vb or c#? aspx solution? Set of .vbs interlinked among them?
This is a old post/goal. In spite of we have not defined any deadline for that, what the heck as time goes by is more urgent for us. A restriction: we can€™t to programme nothing from our sql25k production cluster physically. Any stuff will be done on workstations.
In terms of cost, no problem at all. We are interested in hear thoughts and point of view about which is the most effective way
Thanks in advance,

I have had one tossed at me that I've never dealt with before. While I've done calculations on date parts I'm a little lost on how to proceed. They want a stored procedure that will take date from one field and add three days to it and that would update another field. The three days must account for weekend and holidays.
The date would be receiveddate 12/03/2007 and the due date 12/06/2007. If someone has run into this and has some sample code it would be a great help.
Any help would be appreciated.

Hello,
I just create FLATFILE connection manager from UI, and now I would like save this connection manager for future use. I am not able to do this and now I am really stuck in the middle of coding.
ConnectionManager class has SaveToXML and LoadFromXML methods from IDTSPersist, these methods are not for use, but I am able to save CM to XML, however not load. Every try for loading ends with error 0xC0011008. The XmlNode.Name == "DTS:ConnectionManager"
CM class is not serializable, thus standard .NET feature is not working, also is sealed.
IDTSConnectionManagerFlatFile90 of cm.InnerObject is not serializable either, because it is interface and cm.InnerObject cannot be cast to ConnectionManagerFlatFileClass because is the COM.
Is there any way, how to save and load ConnectionManager besides writing of tons of code for each of connection manager type?
I am able to save and load package with connection manager, but it is not exactly what I want. Also is there possibility to work with XML in packages, but this is not "right".
Thanks
Erik

I need to test an HR application with a future date without changing the system date. If I just rollback the the date fields in the data, it may not work as the application itself might be using getdate() type of functions..
Any thoughts on how to do this w/o touching the system date setting?
Thanks.

Books online "Deprecated Database Engine Features in SQL Server 2005" makes references to "Features not supported in Future SQL Server versions".
http://msdn2.microsoft.com/en-us/library/ms143729.aspx
Will there be an Upgrade Advisor available to help us identify issues with our code any time soon or should we start building our own?

According to SQL Server 2005 Book Online, the following "Important" note applies to SET_ANSI_NULLS and SET_ANSI_PADDING:
"This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature."
However, these options are automatically inserted in the auto-generated scripts (such as CREATE TABLE) in SQL Server 2005 Management Studio.
I am working on new scripts that include these options. What are the replacements for these options? Does the above note apply to ALTER DATABASE options? Please give me advice!
Thanks!

I have a sql server express 2005 database with a table named Events with a column named Date (datetime datatype). I want a query that will display all rows that are either current or future but not past. I suspect there is a simple way of doing this. As a Newbie searching archived threads this is what I have come up with so far. I determine the number of days from present:SELECT DATEDIFF(day, Date, GETDATE()) AS NumberOfDays FROM EventsThis yields number of days from present with positive numbers in the past and negative numbers in the future. Thus setting a WHERE clause to <= 0 would limit my results to present or future events. Something like this:SELECT * FROM EventsWhere DATEDIFF(day, Date, GETDATE()) AS NumberOfDays <= 0The error message states: "Incorrect syntax near the keyword 'AS'"This feels like a clumsy way to approach this problem, but I have to start where I am.Any suggestions on how to proceed will be greatly appreciated.

Hello all!
I want to get into consulting (perhaps a little at first and more once I can support myself on it solely). I am about to start the purchase of a laptop soon, and I want to know which components I should focus on the most. I also want to know which version of SQL Server I should purchase.
From my studies and what I have learned (about to take the test to get my sql server 2005 certificate) I am going to assume that I want to get SQL Server 2005 developer software. However, the part that is not touched on very often, is if I am working with a client that has say, SQL Server 2005 enterprise, x64 exition, and I have developer IA64 edition, would I be able to connect and work on their server?
As far as the hardware is concerned, I am thinking I want a laptop with a large enough screen (I currently get a discount through hp where I currently work and am looking at the models that have a 17 inch screen) so I don't go blind trying to work . I am also thinking I don't need an extremely powerful processor, but I am not sure between athlon and pentium on which I Should choose since I do not have much experience in this area with sql server. I know I want at least 2GB of memory for the simple fact that sql server isnt the only thing I will be doing on the laptop and want some headroom. I also want a large enough hard drive to hold everything, but I definitely want to see if I can get a 7200rpm drive vs a 5400rpm for the simple fact that I have noticed a significant difference in read and write speeds between the 2 drives. I am not too fussed over the video card, as I am not into graphics design or high-end video games (I think world of warcraft is the most intense I have bought in years). I am also thinking that because I wont need to have a very powerful video card, that a mega powerful battery is not super important.
These so far are my thoughts. Please let me know your opinions on what I should focus on/get

I am doing a search on a column of type varchar, the columns all contain dates in the future. When i perform a query
SELECT [CIFPan]
,[CIFMemNum]
,[CIFLName]
,[CIFFName]
,[CIFExpDate]
FROM [FutureSoft].[dbo].[zCIFRecord]
WHERE CAST([CIFExpDate] AS smalldatetime) between '12/01/2000' and '01/30/2015'
I get error:
Msg 295, Level 16, State 3, Line 1
Conversion failed when converting character string to smalldatetime data type.
I can use this same query on an exactly same other field that contains dates in the past. Is there some kind of limitation on the dates as far as them being in the future or past?

Hi,
I've got a time series of the number of new customer subscriptions, which
is the target attribute to predict. The number of subscriptions depends on
various marketing activities, such as mailings, which are known within
the time series for the past.
If I train an ART (MS Autoregression Tree), it learns the trend pattern
as well as the correlations between the marketing activities and the
target (cross-correlations), right?
What I would like to do is, providing the model with some marketing activity
planning for the future and let the model predict the number of new
subscriptions based on a) the past trend pattern and b) the future activities.
Unfortunately a time series algorithm does not provide some kind of scoring for input data.
What would be the best approach to solve this problem? How about linear regression?
But how to train a regression model with trend patterns?
Thanks for your help!

i am trying to find a way to link an 'initial' Sale ID of a product to 'future' Sale IDs of products that will trace back to the original Sale ID.For example, if I call the original sale , 'Sale ID #123', how can i link future Sale ID's (child[ren]) and all future sales to the original Sale ID #123? Can I use a Surrogate Key or similar function?
Parent:Sale ID #123
Children:Â Sale ID # 456,
Sale ID #789,
Sale ID #.....
how I can link the original Sales ID (Parent) to Sale ID's (child[ren]) of future purchases currently existing and in the future going forward?
