Embedded Database Or Runtime Solution
Jul 28, 2006
Hello,
Im doing research for my company for a project we are about to start, but the more I find, the more Im confusing myself. Maybe someone would be so nice to help me a little.
We need a database solution, either licensing (ISV) or i think maybe an embedded database. if its licensing, its not a problem, but after research, im thinking licensing would be a waste of time or too much and theire not enough information to go by just that.
Problem: Need to develop software for a client where there will be around 300 users using the system (not all at once neccisarrily). We are creating this software for them and they want to re-sell it after completion, but they do not want to make their customers purchase a database for the purchase of their software. (because of all types of licensing). We need the database RUNTIME to run on the customers machine to make the software work.
Is there a RUNTIME license for Independant-Software-Vendor(IVS) for redistribution? or would it make sense to embed a database ( for example, the free edition of sql server;embeeded feature :), or maybe firebird embedded database?) We are developing in Visual Studio 2005.
This might sound confusing, thats where im at. For those of you with more experience, hopefully you understand what im talking about.
Thank you. I have 2 days to find a solution. Ill continue looking and post in thread if i find anything new or clearify my problem.

I inherited an existing database application about 6 months ago. I'vefinished converting it to use SQL Server 2000 as the backend (MS Access2002 frontend w/ Userforms+VBA code pointing to the backend).In its current state the application makes use of a ton of embedded SQLstatements and I'm thinking about the best way to clean this up. Itseems like the best way would probably to encapsulate each of the SQLstatements into its own stored proc and then have the MS Accessapplication call the sp. However, this would result in a very largenumber of stored procedures.Anyone have any links or suggestions regarding best practices onremoving embedded SQL scattered throughout a DB app? Thanks.

Is it possible to deploy SQL Server CE "baked into" a DLL? For example, instead of setting the build option to "Content", can I set it to "Embedded Resource"?

Good Afternoon.
I am trying to write a short application within which I would like to embed a SQL Server Express database, all of which would be deployed via ClickOnce through a web site. The installation process seems to be working without trouble, including installation of the .NET Framework 2.0 and SQL Server Express 2005.
When the application launches on the new machine, however, I get a big Microsoft .NET Framework "Unhandled exception" error dialog box that indicates the database already exists and that the database file could not be attached. I am working with a clean virtual machine that I know has never had the database installed on it.
I fear I am overlooking something quite straightforward, but since this is the first time I have ever attempted to build a data-bound application, I am not sure where I am going wrong.
Perhaps the source of the problem, or a related problem, might be revealed even when I run the application in debug mode from within Visual Studio. I can run the application once, but if I try to run it again, I get an error when I try to open the database connection that is similar in content (database already exists...could not attach). I can run the SSEUtil and detach the database and then run the application again in debug mode and it works no problem (the first time!).
Lastly, if I install the application on the machine on which it was developed and make sure the database is detached, it will run without any trouble (even repeatedly). But, on a new blank machine, there is no database listed that matches my database name, so I cannot try to detach anything!?
My apologies for such a novice question!

I'm running VS 2005 Enterprise, and SQL Server 2005 Developer / workgroup edition.I'm trying to follow a few online examples to play around, and some of these examples require that you add a SQL DB to your solution by going:-right click on website-Add new Item-Add SQL DataBase.WHen I do that, I get the error that SQL Express isn't installed. Now the question is, why would I want SQL Express installed when I have SQL server 2005 already installed? My Machine can support it, but it's sort of a waste when I need to run SQL Server 2000, SQL Server 2005 and then SQL Server express all at the same time.Any advice?

I volunteer for a non-for profit group and they have alot of names in amultiple databases. the problem is that some people are in multipledatabases. and if they send out a mailing from multiple databases somepeople get 2 and 3 of the same thing. my idea was to either make or find aprogram that has everyone is 1 database and then make the people part ofmultiple groups. (ex: bill is part of group a and b and im doing a mailingfrom both group i only want 1 piece of mail to go to him).It can be a separate program or with access. that use access now but i cantfigure out how to make my idea work.any question please ask.tiaStephen

Hi Everybody:
We now host 200 G data in SQL Server 7.0 in MSCS. The data will be 1 terabyte at end of the year. The possible solution to host large data with good performance is to migrate data to Oracle or UDB in Unix platform. But we would like to try any possibility in Microsoft world before we decide to migrate data to the other databases.
I need your experience and recommendation about hosting large database in SQL Server with good web performance. Somebody mentions Microsoft tera server. Who has experience using tera server which is still in the beta release? I would like to hear some successful story to handle the large data and understand precisely hardware, software, performance moitoring requirement.
Thank you very much.

Hi
I have been asked to create an archive database which we can use for reporting purpuse . The idea is to have a seperate data base which is an exact copy of the current production database , Once we setup the archive DB . we will remove all 40 days old data from Production database and form that day on should have archive DB with full data and production DB with 40 days old.
I thought go going log shipping or back up restor or snapshortor something but the problem is with all these technology the both data base will come in sync . If i delete data from production that will reflect in arvhive also .
I thought of keeping the 40 days only in production and the rest in archive . But they want to wiew the both data together in one aspx page . so i had think of some joint view . But when the archive data gets grow this would be the main perfomence bottlentck
Can any one help me to select a good solution for this, thanks in advance

Hi, I am noob, so excuse me if this is a stupid question, but I just bought a Learn HTML in 3 Hours book and a learn SQL in 10 minutes book and I was wondering how I would start to go about to build a super flexible enterprise wide web based database application, that is so flexible the users can put in any old crap in the front end and make up new fields as they go. Another one of my requirements is that it perform super fast and be distributed securely across my international multi billion dollar a year company.
So like I know Excel and a little VBA and I know how to use the query builder in Access and I landed this big old contract to revamp this old comapny's infrastructure. Should be pretty easy, right? Everyone is doing it.
So can you guys like help me out for free and stuff?

Hi All,
I have a c# project with an sql express database which is bound to a datagridview via a dataset.
I would like to allow the users to import data into the database from a text file.
How does one go about adding rows and filling in the column data programatically? Do I add the to datagridview? the database? the bindingsource?
Thank you,
Paul

I have a solution with a couple of ssis projects in it. Everytime I open the solution, Visual Studio creates an extra .database file for the project's existing xxx.database file. The solution is under VSS control and VS2005 checks out the project and shows the file as a newly added file.
What causes this and how can I prevent this from occurring?
The files contain this:
<Database xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dwd="http://schemas.microsoft.com/DataWarehouse/Designer/1.0" dwd:design-time-name="d3ce9653-3ac5-4ee5-85c3-7d60b2e5f109" xmlns="http://schemas.microsoft.com/analysisservices/2003/engine">

<CreatedTimestamp>0001-01-01T00:00:00Z</CreatedTimestamp>
<LastSchemaUpdate>0001-01-01T00:00:00Z</LastSchemaUpdate>
<LastProcessed>0001-01-01T00:00:00Z</LastProcessed>

<LastUpdate>0001-01-01T00:00:00Z</LastUpdate>
<DataSourceImpersonationInfo>
<ImpersonationMode>Default</ImpersonationMode>
<ImpersonationInfoSecurity>Unchanged</ImpersonationInfoSecurity>
</DataSourceImpersonationInfo>
</Database>
There are 2 of us working on the solution and the other fellow does not see this behavior.
The files do not show up in the VS2005 solution explorer. If they are user specific as I suspect (impersonation info?), then they should not be added to the .dtproj project file.
Thanks!

VB.NET 2005 Express and SQL Server 2005 Express - NOT saving updates to DB - SOLUTION!
-----------------------------------
The following article is bogus and confusing:
How to: Manage Local Data Files - Setting 'Copy to Output Directory' to 'Do not copy'
http://msdn2.microsoft.com/en-us/library/ms246989.aspx
You must manually copy the database file to the output directory
AFTER setting 'Copy to Output Directory' to 'Do not copy'.
Do not copy
The file is never copied or overwritten by the project system. Because your application creates a dynamic connection string that points to the database file in the output directory, this setting only works for local database files when you manually copy the file yourself.
You must manually copy the database file to the output directory
AFTER setting 'Copy to Output Directory' to 'Do not copy'.
-----------------------------------
The above article is bogus and confusing.
This is rediculous!
This is the most vague and convoluted bunch of nonsince I've ever come accross!
Getting caught out on this issue for the 10th time!
And not being able to find an exact step-by-step solution.
--------------------------
I've tried it and it doesn't work for me.
Please don't try what the article eludes to as I'm still sorting out exactly what is supposed to be happening.
If you have a step-by-step procedure that can be reproduced this properly please PM me.
I would like to test its validity then update this exact post as a solution rather than just another dicussion thread.
Many thanks.
This is the exact procedure I have come up with:
NOTE 1: DO NOT allow VB.net to copy the database into its folders/directorys.
NOTE 2: DO NOT hand copy the database to a folder/directory in your project.
Yes, I know its hard not to do it because you want your project nice and tidy.
I just simply could NOT get it to work.
You should NOT have myData.mdf listed in the Solution Explorer. Ever.
Create a folder for your data following NOTE 2.
Copy your data to that folder. * mine was C:mydatamyData.mdf
Create a NEW project.
Remove any Data Connections. ( no matter what)
Save it.
Data | View Data Sources
Add New Data Source
select NEW CONNECTION ( No Matter what, do it!
Select the database. * again mine was C:mydatamyData.mdf
Answer NO to the question:
Would you like to copy the file to your project and modify the connection?
- NO ( no matter what - ANSWER NO ! - Absolutely NO )
Then select the tables you want in the DataSet.
and Finish.
To Test ----------
From the Solution Explorer | click the table name drop down arrow | select details
Now Drag the table name onto the form.
The form is then populated with a Navigation control
and matching Labels with corresponding Textboxes for each field in the table.
Save it.
1) Run the app.
Add one database record to the database by pressing the Add(+) icon
Just add some quick junk data that you don't mind getting lost if it doesn't save.
YOU MUST CLICK THE SAVE ICON to save the data you just entered.
Now exit the application.
2) Run the app again.
And verify there is one record already there.
Now add a second database record to the database by pressing the Add (+) icon.
NOW add some quick junk data that you WILL intentionally loose.
*** DO NOT *** press the save icon.
Just Exit the app.
3) Again, Run the app.
Verify that the first record is still there.
Verify that the Second record is NOT there.
Its NOT there because you didn't save the data before exiting the app.
Proving that YOU MUST CLICK THE SAVE ICON to save the data you just entered.
Also proving you must add your own code to catch the changes
and ask the user to save the data before exitiing or moving to another record.
As a side note, since vb.net uses detached datasets,
(a copy/snapshot of the dataset in memory and NOT directly linked to the database)
the dataset will reflect all changes made when moving around the detached datasets.
YOU MUT REMEMBER TO SUBMIT YOUR CHANGES TO THE DATABASE TO SAVE THEM.
Otherwise, they will simply be discarded without notice.
Whewh!
I hope this saves me some time the next time I want to start a new database project.
Oh, and uh, for anyone else reading this post.
Thanks,
Barry G. Sumpter

In both VB6 and VB2005 Both are loaded on same computer. When attempting to write to an access database table using ADO I get a runtime error: -2147217887(80040e21) "mutiple-step operation generates errors. Check each status value. " Reading the database is no problem. I only get the errors when writting to database. I have used the following code forever in VB6 and never got this error. Now that I have Visual Studio 2005 loaded on the same machine. I get this error. I get the exact same error when using this code in VB2005. I know VB6 but am just learning 2005. The following code is writting to a database table from various user imputed text and combo boxes. I used basicly the same code in VB2005 and get the same exception error. This code works on machines that do not have VB .net loaded. How do I fix this. My application is useless unless the user can make changes to their data.

Hi,
I am having a Data flow task in For each loop which will gets 100 sourcetable names and 100 target table names...
am having a simpleData flow task which trasferes from OLEDBSource to OLEDBDestination.
I am repeating the Dataflow task which transfers from sourcetablename extracted from for loop to a destination table var.
The problem am gettting is for the first table it is able to transfer correcly because I did mapping for those tables at design time...but for the next coming sourcetable-desttable (which r having different no of cols,datatypes) its giving Validation failed...and...needs to refresh metadata....
is there any way to refresh the metadata of Data flow task (I set the property of OLEDBSource validate external meta to false then also same error is coming)
Thanks

I have a DTS package that transfers some columns defined as varchar(8000).
Sometimes, the values in the columns defined this way have embedded CR/LF in them. When they do, DTS does not always transfer the values to the target.
Any idea why? Workarounds? TIA.

Why is using an embedded SELECT statement faster than using an embedded UDF that has the same exact SQL code within?
Example (not syntax corrected)
Ex1:
SELECT myValue1, myValue2 FROM myTable WHERE aValue = (SELECT Value FROM someTable WHERE myIndex = 800)
is much faster than something like
Ex2:
SELECT myValue1, myValue2 FROM myTable WHERE aValue = (dbo.FN_myUDF(@vmyIndex))
Given that dbo.FN_myUDF has the same code as the embedded select in the first example.
TIA,

I'm looking into a problem a friend is having, and I'll say right offthe bat that I work with with php and MySQL, and not MS SQL.What he is attempting to do (in MS SQL) is take two database fieldsfrom a table (string fields), multiply them together, and put them intoa third field. This third column in the table has not yet been createdthe time of running the query.If it needs to be multiple queries, that is fine. My first thought isto use a simple ALTER query to add the column to the table, then tocall a UPDATE function which uses a select statement inside of it. I'mnot sure if something like this can even be done.// ------------ Suggested queryUPDATE chrisslu SET 'discquantity' = '(SELECTchrisslu.quantity*chrisslu.nr_of_discFROM chrissluWHERE (str(period,6)>=? AND str(period,6)<=?))' WHERE(str(period,6)>=?Andstr(period,6)<=?)// ------------ End Suggested queryIt starts with an UPDATE, but replaces the value to be set with aSELECT statement. I honestly don't even think this query issyntactically correct, I'm just trying to get the general concept down:).So, question the first: Is this type of query possible? The reasonI'm doing this is because I was told MS SQL has no way of storingtemporary variables... otherwise I would just call a SELECT statement,store the variable, and UPDATE the new field from the variable afterthe ALTER statement.Second question: If it is possible, am I on the right track, or doesit need to be entered in completely different than what I have?Third: Regarding the 'type'. Do I need to do any kind of typecastingor conversion of the fields? Both chrisslu.quantity andchrisslu.nr_of_disc are string fields (that is what I was told, theymay be varchar of some kind). In order to use them in a mathstatement, do they have to be floats, or doubles, or something similar?I appreciate any response, I know this was a long winded question.Chris

Hey everyone,
Is there any way to embed a video in a report? It doesn't seem like it but I thought I may be missing something. Maybe directly editing the xml code? Thanks.

Hi there!
I've an embedded image (logo) in my report, and in the preview it looks wonderful, but after deploy the logo doesnt appear in the report (report server).
The url of the dead-link-image is http://hamsql1/Reports$BI/Reserved.ReportViewerWebControl.axd?.
I thought that an embedded image is stored "in" the report, but it seems to be an other place. Is it nessecary to deploy an embedded image too? Is it a problem of permissions (i read it in another threat)? How to set these image-see-permission? Or is there an other problem?
Every idea is very welcome!
Thanks,
Torsten

I have a Select statement that was working just fine:
string sSqlCmd = "INSERT INTO SiloKeywords (Silo_ID, Keyword, UserName) SELECT Silo_ID,'" + Keyword + "', '" + strUsername + "' FROM SiloNames WHERE Silo_Name = '" + Uri + "'";
the PM now wants to capture the internal User, which I have done but I am having real problems with the syntax if the internal User exists:
string sSqlCmd = "INSERT INTO SiloKeywords (Silo_ID, Keyword, UserName, IsInternal) SELECT Silo_ID,'" + Keyword + "', '" + strUserName + "', if EXISTS(SELECT * FROM InternalUsersList WHERE Alias = '" + arrResult[1] + "') 1 ELSE 0 FROM SiloNames WHERE Silo_Name = '" + Uri + "'";
I am completely lost here.
Thanks for any help

Hi,
I am trying to find something like a light version of SQL Server 2k to store data for an application that will be distributed through a cd.
Since we also have a web front end for this application when the user is online, we prefer that we can reuse the code for connection on both the cd and the web.
Any idea what will work?
I have come accross MSDE 2k but was not able to find any documentation on the pros and cons for this product regarding its capacity, the type of data it can handle, security, ...
Please give me some pointer.
Thanks very much.
Baoha.

I was wondering if anyone had tried to embed sql server express in a .net application. Specifically, I want to use it from within the app only, similar to embedded mysql (libmysqld) or firebird. I've seen some articles on sql server express saying this can be done, however there is no info on how do to this. Anyone know how it might be done?

What I'd like to do is use the result of one query as the input foranother. eg:INSERT INTO foo VALUES ((SELECT id FROM people WHERE name = "bar"),10,'foobar') WHEREid = 1;Problem is, MSSQL wants a scalar value. Is there a way around this?Can someone tell me the correct syntax for what I want to do, or is thissomething that will have to be done outside SQL?Err. Hope I've been clear. Thanks for any help you folks can give.

We have text files that are comma delimited, use double quotes as text qualifiers and sometimes have embedded double quotes. The embedded double quotes are escaped with an additional double quote like: below.
"123","product q"
"124","product ""a"""
DTS 2000 had no problem with this- it correctly parsed the files. The 2005 SSIS file connection manager correctly parses this in preview mode. But when the task is executed the task fails with the message "The column delimiter for column X was not found".
What is the recommended approach for this - we have alot of files in this format.
thanks

Hi,
I have a report with background embedded image. I have placed few textboxes on top of them to display data. Every time I set the location of the textbox, it is behaving strangely by rendering at one location one time and changing location next time when it is rendered. I am viewing it in PDF format.
How can I fix the location of textboxes that renders at one location all the time ?
Thanks,
Shyamkumar123
