Upgrade CE 3.1 To 3.5 Why So Difficult?
Jan 6, 2008
I Installed CE 3.1 months ago to play around with it to see how easy or difficult it would be to move from SQL Express to CE. Got it all to work with SQL Managment and VS 2005. Now, months later I am back to really upgrading my product to use CE. Oops, now we are on version 3.5. Decided to stay with 3.1 until I realized transact-sql command "TOP" is not supported in 3.1. So, onto the hours of research to do a simple upgrade. Here's where I stand:
1. Uninstalled CE 3.1. Installed CE 3.5. Oh, if only it were that easy. Visual Studio 2005 is still using the dll from 3.1 and still can only see reference to 3.1 in the GAC.
2. SQL Management Studio now cannot open the .sdf database.
3. There is no mention of using CE 3.5 with VS 2005, only VS 2008. Is VS 2008 a requirement to be able to work with .sdf file in VS? I remember I had to install "Microsoft SQL Server 2005 Compact Edition Tools for Visual Studio 2005" when I went through the first installation of CE. Is this now obsolete if I want to use 3.5? I don't even remember what its purpose was other than I needed it.
It seems there is and upgrade.exe file that need to be run command line to updgrade my .sdf file. Are you kidding?
Has anyone upgraded while still using VS 2005? Any advice is greatly appreciated.

I'm pretty new to this so I'll explain as best I can.
I am building a small DB which will track attendance for employees based on a point system. I believe I'm almost there (with this piece) but am stuck.
The basic concept:
1. Collect all records from the attendance table for the previous 14 day period
2. sum the points column in the attendance table and group by UID, storing in a new table called TOTAL_POINTS ONLY for those UID's which have a value > 0
3. Perform a basic insert into statement on the attendance table for each UID matching those found in the previous TOTAL_POINTS table
Number 3 is where I'm failing and could really use some help.
My code thus far...
-------------------------------
/*Declare local variables for current date and start date.*/
--
DECLARE @DateNow DATETIME
DECLARE @StartDate DATETIME
SET @DateNow=getdate()
SET @StartDate = DATEADD(Day, -14, @DateNow)
--
/*Create table to hold totals for future calculations*/
CREATE TABLE POINT_TOTALS
(UID int, TOTAL float)
/*select ALL records from the table within the above defined date range
and group them by UID tallying the score column*/
--
INSERT INTO POINT_TOTALS
SELECT UID, SUM (POINTS) AS TOTAL_POINTS
FROM attendance
WHERE date >= @StartDate
GROUP BY UID
--
/*If the TOTAL_POINTS > 0 for the 14 day period, insert a record in to the
attendance table which deducts .5 points for the UID in question*/
*** This is where I'm failing ***
--This was just to make sure I was returning the correct results to the POINTS_TOTAL table.
SELECT UID FROM POINT_TOTALS
WHERE TOTAL > 0
/*All I want to do now is for each of the UID's in the POINT_TOTALS table,
I want to perform a basic insert on the ATTENDANCE table where the UID's in both
match. I would think this to be fairly simple but I can't seem to figure it out.
*/
DROP TABLE POINT_TOTALS

--This is works
SELECT *

WHERE age like '18'
--This gives me an error
SELECT clientId, firstName, age
from vwClientsByAge
WHERE age < CONVERT(int, '18')
Error: The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.
Whats wrong with the conversion?
However, this works:
SELECT age
from vwClientsByAge
WHERE age < CONVERT(int, '18')
What is wrong?

Hey i have a query i need help with.
I have a table where i have 4 columns in it which i need to group together and then sum up a cost column also. I want to sum up the columns where i have a parent and and child and then i want to sum up the other column where i have only a child.

HiI am trying to produce an update trigger. I understand the concept ofdelete and insert triggers without a problem. Unfortuantely, theupdate triggers do not have particularly simple documentation in BoL.So, can someone please explain to me, quite simply how I would producea trigger on the following:I have table 1 which we'll call simon. In here are various columns androws. I also have table 2, called simon_a, my audit table.Whenever anything is updated or deleted in simon, I want it sent tothe simon_a table. Delete, as above, is fine since it's conceptual buthelp me out on the update one. I cannot seem to figure out how to getthe information from the table before it's updated.As ever, champagne and beer for the successful answer.With thanksSimon

suppose I have the following table:CREATE TABLE (int level, color varchar, length int, width int, heightint)It has the following rows1, "RED", 8, 10, 122, NULL, NULL, NULL, 203, NULL, 9, 82, 254, "BLUE", NULL, 67, NULL5, "GRAY", NULL NULL, NULLI want to write a query that will return me a view collapsed from"bottom-to-top" in order of level (level 1 is top, level 5 is bottom)So I want a query that will returnGRAY, 9, 67, 25The principle is that looking from the bottom level up in each columnwe first see GRAY for color, 9 for length, 67 for width, 25 forheight. In other words, any non-NULL row in a lower level overridesthe value set at a higher level.Is this possible in SQL without using stored procedures?Thanks!- Robert

Why have you made connecting to a sql server express database so difficult?
I have it working locally, but going to production has been nothing but a nightmare.
I can't even connect locally on the production box.
I am on a dedicated server and my login is an Admin on the box. I have just installed SQL Express + the fancy management interface.
I have made a copy of my database that I was connecting to dynamically (which was failing remotely) and I have attached it to the server. I have made myself a user of the database and granted my self evey permission available.
I have turned on impersonation in my web.config. The database knows it's me trying to connect and STILL denies me when I'm actually ON the production server. It is not even a remote connection problem.
How can I sit there an look at myself as a user of the database in the admin interface, yet I cannot connect via a web app. With SQL server 2000 and MSDE it was soooo simple....
Here is a snippet from my web.config
<connectionStrings>
<remove name="LocalSqlServer"/>
<add name="LocalSqlServer" connectionString="Data Source=localhost;Integrated Security=True;Initial Catalog=TEST" providerName="System.Data.SqlClient"/>
...
</connectionStrings>
Here is the error:
Cannot open database requested in login 'TEST'. Login fails.
Login failed for user 'DEDICATEDquick'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: Cannot open database requested in login 'TEST'. Login fails.
Login failed for user 'DEDICATEDquick'.
I have a screen shot of the admin interface to prove I am a user.
This should be a 5 minute task that has eaten up days.
So frustrated...

Hi.
I am developing for a system that receives an input from an external modem.
The Transaction is split into 2 sections,
Section 1 = grants the transaction ID,
Section 2 = deliver the transaction Data.
I have 2 corresponding tables,
One called tblremoteunitrequestID (Where the transaction ID is granted)
The other called tblremoteunitrequests (Where the transaction is completed, about 1 second later)
I am writing a diagnostic report that determines if the first part of the transaction completes but the second part fails.
I am having difficulties designing the SQL for this.
Here is some sample data for tblremoteunitrequestID: (The first stage of the transaction)
RecordDate | Serial
13/11/2006 14:00:36 0000-0000-0000-0006
13/11/2006 14:00:30 0000-0000-0000-0004
13/11/2006 13:59:04 0000-0000-0000-0092 (This didtn transaction didnt complete)
13/11/2006 12:15:22 0000-0000-0000-0092 (nor did this one)
13/11/2006 10:31:54 0000-0000-0000-0092
13/11/2006 10:00:29 0000-0000-0000-0006
Here is some sample data for tblremoteunitrequests: (The second stage of transaction, 1st stage has to be completed beforehand)
DateReceived | Serial
13/11/2006 14:00:37 0000-0000-0000-0006
13/11/2006 14:00:31 0000-0000-0000-0004
13/11/2006 10:31:56 0000-0000-0000-0092
13/11/2006 10:00:31 0000-0000-0000-0006
13/11/2006 10:00:25 0000-0000-0000-0004
13/11/2006 07:19:13 0000-0000-0000-0020
From this data I can see that serial number 0000-0000-0000-0006 Successfully completed part 1 and part 2 of the transaction, as did serial number 0000-0000-0000-0004.
Serial number 0000-0000-0000-0092 had trouble, it connected at 13:59:04 (tblremoteunitrequestID) but part 2 didnt complete, so it wasent saved in tblremoteunitrequests. The same happened at 12:15:22 but at 10:31:54 it was successful so it was saved.
I Only want to display the transactions that didnt complete, sounds easy huh?
This is what I hope to get in my Results table:
DateReceived | Serial
13/11/2006 13:59:04 0000-0000-0000-0092
13/11/2006 12:15:22 0000-0000-0000-0092
I was experimenting with T-SQL today, this is what I have done so far:
SELECT DISTINCT
TBLRemoteFeildUnitRequestID.Serial, TBLRemoteFeildUnitRequestID.RecordDate,
CASE WHEN TBLRemoteUnitRequests.DateReceived BETWEEN DATEADD(SECOND,-1,TBLRemoteFeildUnitRequestID.RecordDate) AND DATEADD(SECOND,10,TBLRemoteFeildUnitRequestID.RecordDate)
THEN ' Ok'
ELSE ' Not ok'
END AS PROBLEM
FROM TBLRemoteFeildUnitRequestID LEFT OUTER JOIN
TBLRemoteUnitRequests ON TBLRemoteFeildUnitRequestID.Serial = TBLRemoteUnitRequests.Serial
WHERE TBLRemoteFeildUnitRequestID.RecordDate BETWEEN DATEADD(WEEK, - 2, GetDate()) AND GetDate()
ORDER BY RecordDate DESC
This kinda worked, but it caused records that satisfied the between condition to be displayed twice, once as "Ok" and once as "Not ok".
Heres a sample of the result I got:
Serial | RecordDate (1st part of transaction) | Status
0000-0000-0000-0006 2006-11-13 14:00:36.000 Ok (Duplicated)
0000-0000-0000-0006 2006-11-13 14:00:36.000 Not ok
0000-0000-0000-0004 2006-11-13 14:00:30.000 Not ok (Duplicated)
0000-0000-0000-0004 2006-11-13 14:00:30.000 Ok
0000-0000-0000-0092 2006-11-13 13:59:04.000 Not ok (Correct) (Not duplicated)
0000-0000-0000-0092 2006-11-13 12:15:22.000 Not ok (Correct) (Not Duplicated)
0000-0000-0000-0092 2006-11-13 10:31:54.000 Not ok (Duplicated)
0000-0000-0000-0092 2006-11-13 10:31:54.000 Ok
0000-0000-0000-0006 2006-11-13 10:00:29.000 Ok (Duplicated)
0000-0000-0000-0006 2006-11-13 10:00:29.000 Not ok
I have just about had enough, I have wasted an entire day on this

Hello:
I am working with an application in mssql 65.5, with sp4.
I have the database option 'truncatelog on checkpoint' set, there are no transaction log dumps taken at this time.
We plan now that y2k is over to upgrade to sp 5a. I am not not sure the new configuration
parameter 'logLRU buffers'(I don't have the sp5a readme text with me now) in our situation.
Here is our situtation with the transaction logs: The log, mostly with month-end high actvity,
fills up when long-running, high activity transactions are run.
The log gets to 100% sometimes rather quickly and sometimes near that or above 80%easily.
We check with dbcc open tran and there are no current transaction running. We expand the log just a little.
But it still shows 100@ used when we run dbcc sqlperf (logspace).
Here's the rub: when we try to dump the log, with wither or both back-to-back: dump tran abcdb
with truncate_only and then dump tran with no_log still nothing happens.
Sometimes we stop and start the mssql server and that helps but not always and sometimes when
we are really desperate we stop/start the NT server box(at off hours). Sometimes, the transaction log
reduces to nearly 0% used when we run dbcc sqlperf (logspace) and sometimes not. So we run dump tran
a couple of more times. We wait for several minutes usually to if the dump tan started and if it shows up
under EM under curent activity
This is becoming very frustrating and dangerous as well.
1) has any one had similar experiences with mssql 6.5 sp4?
2) Can anyone advise what we can do to more easily to dump the transaction log? Are we doing
any thing really wrong?
3) Would upgrading to sp 5a really help or should we just start planning upgrading to mssql 7.0?
Any suggestiosn you can furnish will be helpful. Thanks.

I'm writing a workflow management application for my work, and its somewhat complicated, here's a general idea of how it works:
- Anything that a company does is defined by a workflow.
- A workflow consists of tasks.
- Some tasks in a workflow can't be started until other tasks have been completed. If task A can't be started until tasks B and C are finished, then task A depends on B and C.
You might imagine that a bank has a workflow for handling a house loan. Before a bank could sign a contract with an applicant, they'd need proof of house ownership, but before they could get proof of house ownership they need an applicant's proof of identity like a driver's license or military ID.
Here's an oversimplified visual:
Each arrow points to its dependency. Each task can have multiple dependencies.
The setup above is represented in the database by a Tasks and a Dependencies table. Tasks has an ID field, and Dependencies has a TaskID and DependencyID field which are both foreign keys to Tasks.ID.
Code:
[Tasks]
ID Status Name
-- ------ ----
1 Done Start Processing Loan Application
2 Done Photocopy applicant's driver's license
3 NotDone Photocopy proof of house ownership
4 NotDone Get a copy of applicant's W-2 forms
5 NotDone Perform credit check on applicant
6 NotDone Sign loan contract
[Dependencies]
TaskID DependencyID
------ ------------
1 0
2 1
3 1
4 2
5 2
5 3
6 4
6 5
Tasks has a many-to-many relationship with itself.
Here's the hard part:
- A task can't be started until all of its dependencies have been completed.
- after a task is completed (meanings its status is marked "done"), I need to return a list of all the new tasks that are ready to be started.
When TaskID 2 is marked "Done", then TaskID 4 is ready to begin; however, TaskID 5 is not ready to begin since it depends on 2 and 3, and 3 hasn't been completed yet.
The requirements of the query are very simple, but the implementation is difficult.
I'll post a prelimenary solution in the next post:

Hello,Here is a brief summary:Table 1 = All Accounts- with fields such as Customer ID and Account #Table 2 = Deposit Balance Table- with fields such as Account #, BalanceTable 3 = Loan Balance Table- with fields such as Account #, BalanceAll accounts are either deposit accounts or loan accounts. What I needto do is to gather information about total balances in both depositsand loans for each customer. I haven't been able to hit the right queryfor doing this. I can easily get information about one or the other,such as the following:SELECT All_Accounts.Customer_ID, COUNT (DISTINCT(Deposit_Balance_Table.Account_Number)), Sum(Deposit_Balance_Table.Balance)FROM Product_Table, Deposit_BalanceWHERE (Product_Table.Account_Number=Deposit_Balance.Acco unt_Number)GROUP BY Product_Table.Customer_ID ORDER BY 1Which will give me one row for each user, and show me the total numberof deposit accounts each customer has and a sum of the balances in eachof those accounts. I can make a similar query involving Loan Accounts.As soon as I try to draw both, however, I wind up below my depth.Something to do with the handedness of my joins, I believe. Often Iwill get one column of information (either deposits or loans), or thequery will fail because the join I'm attempting is invalid, etc. I needto take every row in the All_Accounts table, match each one to itsbalance in either the Deposit or Loan table, and then group them all bythe Customer ID and sum them, so that I can find out the totalrelationship balance per customer. Any help would be appreciated.

Hi all,
i have a table containing 24 columns, i would like to generate a new table by input the program gets from the user concurning of the columns he would like to see.
sound like an easy "select ? from table", but the thing is that how can the function know how to get a different number of variables, i mean, one time the user will want to see one column, and afterwards he will want to see 10 columns, is there a solution except generating 24 functions?.
i looked in all kinds of SQL tutorials and nothing came up so i came here, tnx for your help!.

I created a package from an Import Data Wizard, in 2000 you had the option to schedule that job, right then and there, but apparently that was too convenient, anyway... After creating my stored package within the database, I try to set up a job to run that package, it is pretty straightforward and I think it is going well until I try to execute the job and I get the following error.
Message
Executed as user: servernamesystem. The package execution failed. The step failed.
So after some investigation, I believe it is a permissions issue, and at that time (default install) all services were running under "Local System". I had created the package with my domain account which is in the administrators group of the server. So, I added another service domain account in the administrators group and changed the services to run under that account. Again. No Dice, now I get this error...
Message
Executed as user: domainservice_account. The package execution failed. The step failed.
Any help would be appreciated at this point in time.
Thanx

How do you shrink the tempdb in SQL Server 7 after you allocated a large space to it but later realized you allocated too much.... I need to reclaim the space allocated to it but when I try to change the size or do a shrinkdb it either tells me I cannot shrink it smaller than allocated size or it shrinks tempdb to current (which is too large)... I looked online but could not find anything...
Any suggestions or assistance would be much appreciated... up to my eyes in tempdb..... Bill.

Hi! I am rather new to SQL, and could use some help. I have a table with lots of records, with fields like this:
TableA.Batch
TableA.Wafer
TableA.DieID
TableA.Param
TableA.Value
For each batch, there are ~25 wafers. For each wafer, there are thousands of dies. For each die there are several parameters, and for each die and parameter there is a value.
I want to calculate the median and robust sigma (inter-quartile range/1.35) per wafer, for a parameter. The following code works perfectly for me:
DECLARE @Q1 FLOAT, @MEDIAN FLOAT, @Q3 FLOAT, @SIGMA FLOAT, @x INT, @y INT, @z INT
SET @Q1 = SELECT TOP 1 value FROM (
SELECT TOP 25 PERCENT value
FROM TableA
WHERE batch=@x
AND wafer=@y
AND param=@z
ORDER BY value) Quartile1
ORDER BY value DESC
SET @MEDIAN = SELECT TOP 1 value FROM (
SELECT TOP 50 PERCENT value
FROM TableA
WHERE batch=@x
AND wafer=@y
AND param=@z
ORDER BY value) Median
ORDER BY value
SET @Q3 = SELECT TOP 1 value FROM (
SELECT TOP 25 PERCENT value
FROM TableA
WHERE batch=@x
AND wafer=@y
AND param=@z
ORDER BY value DESC) Quartile3
ORDER BY value
SET @SIGMA = (@Q3-@Q1)/1.35
SELECT @MEDIAN, @SIGMA
Ok, if you are still there: I need to do this for hundreds of wafers, and hopefully without having to manually set the batch and wafer numbers. I'm using MS SQL server by the way. As far as I've understood, there is no for-loop in SQL, and I can't see how I can do this by using GROUP BY.
Any help is very appreciated.

Hi,I have a table as followingaa Text1 aa, Join Bytes!, 15267aa Text1 aa, Join Bytes!, 16598aa Text1 aa, Join Bytes!, 17568aa Text2 aa, Join Bytes!, 25698aa Text3 aa, Join Bytes!, 12258I have to write a query as follows ...SELECT DISTINCT TOP 500 fldText, fldContact, fldItemidFROM tableWHERE fldCat = 10 AND CONTAINS (fldText, 'Text1')In the example you can see the table has rows in which text and contact ordouble but with different itemid's. Now my employer wants me to show only 1row when text and contact or the same. He doesn't mind which itemid I show.... but I have to show one.I've an idea of how to do this using a cursor and a temporary table but Iguess that will be fatal for the performance because then I have to loopthrough all selected rows, check each row with all other rows and store theprimary key in the temporary table if dedected it isn't double. AfterwardsI can execute ... SELECT ... FROM TABLE where primary key in (selecttemp_primarykey from #temptable).I hoped I could do everything in 1 "easy" SELECT but I should not know how?Any ideas are much appreciated.Thanks a lot.Perre Van Wilrijk.

If you know the answer please explain what you're doing if possible, that'll help me :)I have the following tables:CREATE TABLE [dbo].[tblUserData]( [UserCode] [int] IDENTITY(1,1) NOT NULL, [UserName] [nvarchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL, [DisplayName] [nvarchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,) ON [PRIMARY]CREATE TABLE [dbo].[tblFriends]( [UserCodeOwner] [int] NOT NULL, [UserCodeFriend] [int] NOT NULL, [createdate] [datetime] NOT NULL CONSTRAINT [DF_tblFriends_createdate] DEFAULT (getdate())) ON [PRIMARY]in tblFriends relations are stored twice, so for a relation between user 5 and 6, there will be 2 rows: 5-6 and 6-5Now, I want to get the columns (UsercodeOwner,UsercodeFriend,createdate,username,displayname) for relations that were created in tblFriends in the last 10 days for the FRIENDS of a person with usercode 5.Example:tblUserdata5 peter Petertje6 john Johnny11 simon SimonSays15 monique MontjetblFriends5 6 'createdate 30 days ago'5 11 'createdate 5 days ago'6 5 'createdate 30 days ago'6 11 'createdate 3 days ago'6 15 'createdate 7 days ago'11 5 'createdate 5 days ago'11 6 'createdate 3 days ago'15 6 'createdate 7 days ago'The resultset for a query on usercode 5 would now be (usercode1, username1, displayname1,usercode2, username2, displayname2,createdate):6 john Johnny 11 simon SimonSays 'createdate 3 days ago'6 john Johnny 15 monique Montje 'createdate 7 days ago'As you can see each relation is only returned twice even though there are always two entriesWhat would be the SQL statement, if possible without temp table..Thanks!

Our customer (of our ecommerce system) wants to be able to preservedeleted entities in the database so that they can do reporting,auditing etc.The system is quite complex where each end user can belong to multipleinstitutional affiliations (which can purchase on behalf of the user).The end user also has a rich trail of past transactions affiliationsetc. Thus in the schema each user entity is related to many otherswhich in turn relate to yet others and so on.In the past when a user was deleted all of his complex relationshipswere also deleted in a cascading fashion. But now the customer wantsus to add a "deleted" flag to each user so that a user is never_really_ deleted but instead his "deleted" flag is set to true. Thesystem subsequently behaves as if the user did not exist but thecustomer can still do reports on deleted users.I pointed out that it is not as simple as that because the user entityis related to many, many others so we would have to add this "deleted"flag to every relationship and every other entity and thus have"deleted" past purchases, "deleted" affiliations - a whole shadowschema full of such ghost entities. This would overtime degradeperformance since now each query in the system has to add a clause:"where deleted = 0".I assume this is a standard problem since many organizations must havethis need of preserving deleted records (for legal or other reasons).I tried to talk them into creating a simple audit file where all thedeletions will be recorded in XML but they were not too happy withthat.Is there a more satisfying solution to this than have this "deleted"flag?Thanks for your help,- robert

Hi All,I have what seems to me to be a difficult query request for a databaseI've inherited.I have a table that has a varchar(2000) column that is used to storesystem and user messages from an on-line ordering system.For some reason (I have no idea why), when the original database wasbeing designed no thought was given to putting these messages inanother table, one row per message, and I've now been asked to providesome stats on the contents of this field across the recordset.A pseudo example of the table would be:custrep, orderid, orderdate, comments1, 10001, 2004-04-12, :Comment 1:Comment 2:Comment 3:Customer askedfor a brown model2, 10002, 2004-04-12, :Comment 3:Comment 4:1, 10003, 2004-04-12, :Comment 2:Comment 8:2, 10004, 2004-04-12, :Comment 4:Comment 6:Comment 7:2, 10005, 2004-04-12, :Comment 1:Comment 6:Customer cancelled orderSo, what I've been asked to provide is something like this:orderdate, custrep, syscomment, countofsyscomments2004-04-12, 1, Comment 1, 12004-04-12, 1, Comment 2, 22004-04-12, 1, Comment 3, 12004-04-12, 1, Comment 8, 12004-04-12, 2, Comment 1, 12004-04-12, 2, Comment 3, 12004-04-12, 2, Comment 4, 22004-04-12, 2, Comment 6, 22004-04-12, 2, Comment 7, 1I have a table in which each of the system comments are defined.Anything else appearing in the column is treated as a user comment.Does anyone have any thoughts on how this could be achieved? The endresult will end up in an SQL Server 2000 stored procedure which willbe called from an ASP page to provide order taking stats.Any help will be humbly and immensely appreciated!Much warmth,Murray

Hello,
I am fairly new to SSIS and do not have a wealth of 'in-depth' knowledge of it and I am running into some problems.
I am part of a team that is using Agile techniques (Scrum based) to implement a reasonably complicated system. This system has the requirement for numerous file feeds and multiple transactional database instaces whos base data is driven from a master seed database.
We are getting to a point where we are starting to hook up alot of the infrastructure and I am running into problems. Especially with the continous evolution of the database. Every iteration, the SSIS packes break because of DB changes. This is a little scary to me because I am starting to see SSIS as adding multiple points of failure to the system. Agile is based on refactoring often and that includes the database for this project. Every database change either breaks or requires a change to the SSIS packages that moves data from file feeds and staging databases to the master seed database. This problem is even more pronounced when considering the processes that move data from the seed database to the transactional databases. It discourages changing the database which is a really bad thing because that can lead to code archtecture smells and adds fragility.
Anyone have any input on this subject?

Hi Guys!
I have created a big list of packages, some calling others. They all work fine from my computer using Visual Studio.
When I try to deploy them (building them with deployment turned on and running them either directly from Management Studio or as a job) I get the errors with the password of connection strings. From what I read so far its the encryption process that kills it.
I have tried to add a password to some packages, but it still didnt work (only when run directly on my computer in management studio after deploying to SQL Server, but not as a job).
I have tried to change ProtectionLevel to SecurityStorage, wouldnt let me save in Visual Studio (I understand it is ot allowed in VS because you are saving to File System, how the hell am I supposed to save it to anything else? why is it showing there if its not even valid?).
If anyone can please give me the steps to doing it properly, that would be awesome. I simply need to run the packages from SQL Server! thats all! I have no idea why it has to be soooo difficult :/

Expression-based connection strings are great but they are specific to each report which makes them difficult to maintain. Shared expression-based connection strings are not supported.
I'm looking for a way around this. I'm hoping to write a custom data extension, and in the custom data extension, do all the "dynamic" logic that sets the connection string (which you normally would be doing in your expression-based connection string).
I know the above can be done. What I don't know is how, inside a custom data extension, to get the value of expressions like User!UserID? (I want the connection to run under stored credentials, but I want to customize the connection string and add a property to it based on the UserID who is logged into Report Manager.)

Let's say I have a list of IDs called EntryID and each EntryID can belong to ONE table out of a group of six, what is the best way to get a listing of these?
For example:
select r.*
from #Reminders r
left join mytable1 mt1 on (r.EntryID = mt1.EntryID)
left join mytable2 mt2 on (r.EntryID = mt2.EntryID)
left join mytable3 mt3 on (r.EntryID = mt3.EntryID)
left join mytable4 mt4 on (r.EntryID = mt4.EntryID)
As you can see, #Reminders has one field called EntryID (and many rows).
In my example above, only ONE of those tables will actually be able to join but I have no idea which one has the matching EntryID.
What is the best way for me to do this? I want to grab "ReportStatus" from the corresponding "mytable"... (each "mytable" has a ReportStatus column)
