Hello,
I'm looking for a tutorial or some sample code to save a file in sql server with c#. So far I have not been able to find a anything I could use as most tutorials are in VB. I'm using the varbinary max type to store the file. The part I need help with is selecting the file and converting it using the Stream object, not the SQL insert statements.
Thanks,
Arnold
Hi There,
I am new to VC# and SQL Express. I am currently trying to find a way to store user selected files into SQL Express. I am using a column with the varbinary(MAX) data type. My current thought is to give the user a open file dialog box, and let them select the file they want to upload. On closing this dialog box, I convert the file selected into a file stream and insert into SQL Express.
Is this method a good one? If anyone else can give me pointers or hints to better methods, please do!
Thanks,
Ke
Hi experts;
I have a problem with unicode character 0x2300
I created this table
create table testunicode (Bez nchar(128))
Insert Data
insert into testunicode (Bez)values('¢')
with 2 Unicode characters
= 0x2300
¢ = 0x2122
Selecting the data
select Bez from testunicode
I see
"?¢"
¢ = 0x2122 is ok but instead of 0x2300 there is 0x3f
When I modify the insert statement like that ( 8960 = 0x2300 )
insert into testunicode (Bez)values(NCHAR(8960)+'¢')
and select again voila i see
"¢"
Does anyone have an idea?
Thanks
I am trying to 'load' a copy of a SQLServer 2000 database to SQLServer 2005 Express (on another host). The copy was provided by someone else - it came to me as a MDF file only, no LDF file.
I have tried to Attach the database and it fails with a failure to load the LDF. Is there any way to bypass this issue without the LDF or do I have to have that?
The provider of the database says I can create a new database and just point to the MDF as the data source but I can't seem to find a way to do that? I am using SQL Server Management Studio Express.
Thanks!!
I have a table that I'm inserting a file into and using the Image data type to store the binary object. Now the code below works fine for files around 1.5 MB, but anything larger and it's like the code won't even execute and I get a Page Not found error.
I'm in the process of running some traces to find out what's going on in the backend, but I'm assuming there's something amiss with my code. The Image data type should handle files that size with no problem but for some reason it isn't.
Does anyone see anything wrong?
Thanks

I did some quick Googling and didn't find the article of my dreams here. Any experience with storing files in the db in 2005? Any opinions?
Here's the deal. We have our new 'Enterprise' software being designed and written in St. Petersburg (not FL) and I'm reviewing the design for dealing with letters and forms that are generated as hard copy from our business (by the thousands per month) and sent to clients for review, signature etc. Then they are returned by fax or snail mail.
The current design has all of these being stored in image data type columns in the database--storing saved files of the actual outgoing stuff and saved files of the stuff that comes in (scanned copies or the files from our fax server).
This screams 'BAD IDEA' based on our experience doing this in SQL Server 2000. We get things like 23 page faxes from Dr's offices, large packets of FMLA forms returned, etc. In 2000 they tended to get rather large when stored in the DB and caused us all kinds of headaches when Microsoft changed how it recognized and displayed certain types of files, e.g. tiffs.
Further, the outgoing stuff is largely boilerplate with added fields from the db--name, address, a few dates. My proposed design for outbound notifications and forms was to keep only references to the template used, the date created, and an id to link it to the personal info of the schmoe to whom it was sent--essentially, store which document template and then just enough data to map to the variable content that is pulled from the db. Then you can recreate the file that was printed and mailed at any time in the future, but you don't actually save the .doc (or Word .xml) anywhere, not in the file system, not in the db.
The current developers feel this is way too much work to design--and it is certainly more effort than just generating .docs/.xml files via a merge with Word and then stuffing those into the database. They also argue that having them in the db makes them 'more secure' and more 'accessible' to users around the globe.
Does anyone know if the image storage is any better in 2005 than 2000? The .docs & .tifs we used to store just about tripled in size when we put them in the db in 2000. Plus there were the defrag issues and generally it was an unsatisfying experience.
Does anyone know what the advantages/disadvantages of generating Word .xml files might be? Can they be stored as xml data type in SQL Server? Perhaps this is a better option?
If anyone has the time to digest this, please send opinions.
Thanks!
Hi There,
Can I store flash files in the database. I have a table with one of the columns as varbinary datatype. Previously, I was saving images (as filebytes) into this column. But now I need to implement something to store the flash file. So, is it possible to store flash files in the database and retrieve them and display them in an asp.net page?
Thanks a lot for your suggestion!!
I have an app that uses a sqlserver 2000 jdbc driver to connect to a sqlserver 2000.
Is it possible to do a direct replacement of sqlserver 2000 with sqlserver 2005 express just by reconfiguring the app to point to the express? The app would still be using the sqlserver 2000 jdbc driver to try and make the connection.
If that is a possibility, what can be some differences in the configuration? Previously with 2000 the config information I entered is:
server name: "machinename"( or ip). I've also tried "machiname/SQLEXPRESS"
DB name: name of db instance
port: 1433(default)
user and pass.
My attempts so far results in
"java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket."
and
"java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Unable to connect. Invalid URL."
I want to store a Zip file as a BLOB, but I get an error:
"File 'C:<path of mdf file> ' appears to have been truncated by the operating system. Expected size is 2560KB but actual size is 1536KB "
whenever the BLOB exceeds 1MB.
Any suggestions? How can I store larger .ZIP files to the Database?
I am using MS SQL 2005 Express and the data type that I gave for the column to store Blob is "varbinary(MAX)".
I am inserting byte array in to this field.
It works fine for a zip file less than 1MB but as soon as the zipped file size increases beyond 1MB, lots of error pop-up and then the database is not readable. Its says that, the data in the data base may have been corrupted...
Hello all
I built an application that connect to MS SqlServer2005 using Native driver (sqlncli.msi) I install that file from MS site, I need to deply my application to the end-user, and I would like to know what files do I need to deploy to make sure the application is gona run okay on the client PC's.

Any recommendations on the best way to do this would be greatly appreciated.
thanks!
Hi to all GURUS,
I am very (almost two days) new to SQL Server Express (in fact SQL Server). In my old applications I am using VB.Net 2005 Express with MS Access database and now I wants to go for SQL Server Express.
One thing I am unable to find till now is : if SQLServer Express is installed on my Server machine (say ServerPC) with attached database (say MyDB.mdf), how I can access it through ADO.Net 2.0 from client machine. (using VB.Net Express)
Thanks and hope you will encourge me to use SQL Server .
Ok from what I understand, sqlserver 2005 is FREE, and it is not limited by the number of concurrent connections etc etc.
So this means you can put sqlserver 2005 express on a dedicated server, and it can pretty much handle all the load you can throw right? (except if your say running myspace hehe)
Comments?
I would really like to be using SQLServer Express 2005 for some desktop database applications and replace MSDE. However, I am using VS.NET 2003 and so far I have not been able to discover if that combination will work.
Thanks,
Sid.
I have followed the link to download SP1 of SQLServer 2005 Express Edition, but, on that page nowhere it is mentioned that downloads offered are of SP1, it simply says that SQLServer 2005 Express edition.
What is the correct link and am I really on the correct page of SP1 ?
When I try to run the install it detects some previous versions
components. The remove all previous beta components fails and I have
removed everything from the Add/Remove Programs.
Any advice would be helpful

I am building a Visual Web Developer site with a SQL Server 2005 Express backend. I am trying to create the login page, I have written a stored procedure that takes in the username and password and returns a value which indicates whether the user is valid or not.
My problem now is integrating this stored procedure into the page. In Visual Studio 2003 you could just drag and drop the stored procedure from the Database Explorer window and it would create the neccessary SQLCommand which you can then pass parameters too and recieve return values, i.e:
sqlcommand1.Paramters[ "@username" ].value = TextUsername.Text;
sqlcommand1.Paramters[ "@password" ].value = TextPassword.Text;
sqlConnection1.Open();
sqlCommand1.ExecuteNonQuery();
Int Result = (int)sqlcommand.Parameters["@returnvalue"].value;
sqlConnection1.Close();
I see in VWD there are SqlDataSource's etc, is this what I need to use to do what I'm looking for and how do they exactly work? Ideally what I'm looking for is when a user clicks login, the contents of the 'username' and 'password' text boxes are queried against the database. What controls and configuration is required to achieve this?
Many thanks in advance,
Mervski
Iām working with an Sqlserver 2005 Express database on my local machine, and using vs.net 2005.I need to enable the sqlserver cache by the way:
aspnet_regsql -E -d Northwind -ed
I encountered the remote connection problem(error:40).The northwind database was restored to the sqlserver 2005 express by the db file downloaded,and I added the ASPNET user.I also enabled the TCP/IP by using SQL Server Configuration Manager.
But all the web application connected to the Northwind database is working through the connection string:
"Data Source=WKS-DEV-04SQLEXPRESS;Initial Catalog=Northwind;Integrated Security=True"
Any help will be much appreciated, thank you very much for reading my post

Bummer. I can't remember the SA password. I had setup a user account, but I can't change anything or add any new accounts using this login. I can't get in using the windows authentication method no matter how I am logged into this machine.
Any suggestions? I have never been able to use Windows Authentication. There must be something I'm missing here. I have spent hours and hours trying to get into this machine. I just want to replicate a database. This is very frustrating.
Thanks guys.
Hi,
I can't seem to set up SQL server authentication for SQLserver 2005 Express edition..
I simply can't find the settings for that. I have Management Studio Express installed and I can see the SA user but I can't login using that user.. I know that there's supposed to be a setting for turning on SQL auth. but it's not like it used to be in Enterprise manager :) so I can't find it.. ;/ I couldn't find any documentation on how to do this so I thought I'll try here..
(I need SQL auth for my project :) - it must be done with that..)
Thanks in advance,

pls help
Hi,
Apologies if this has been asked before, i've done a search but can't find a definitive answer.
I've created a table in an SQLExpress 2005 db using Server Managment Studio Express.
My intention is to use GUID fields as surrogate PK's. I therefore wanted to add a additional index to prevent duplicate records being added to the table. Not having used SQLServer before could someone confirm or deny that this is the correct way to do this. The PK field [EPISODEID{unique identifier}] is set as a non-clustered index. And i've created a second clustered index using the two fields that create a unique record. I've added a screen shot if that is any help.
Thanks
Chris

Is there a way to store a time in the SQLServer database, without the date? (e.g. just simply "HH:MM" instead of "HH:MM DD/MM/YYYY" which it stores it in)
View 1 Replies View Relatedhi,
i would like to store just the time part in sqlserver 2000. time part with default date which is 1899 - 12- 30 in my sql server. but i read some articles which mentioned default date as 1900 - 01 - 01. i am not sure which one but if i enter just the time part in my sql server and do the query i get 1899 -12-30 and (time part). anyway, i am just wondering whether it is possible to set the trigger or constraints to strip off the date part of entered value and replacing it with default is ok.
the reason is i need to some queries on time part only which is giving some problem now.

View 2 Replies View RelatedApparently you cannot go backwards. Once 2005 Express is installed, even removing it does not allow you to setup MSDE 2000 again. So there is no "trying it out" option.
Unfortunately, our software does not use 2005 Express. I tried it out, and now have a useless testing workstation that can't have MSDE 2000 installed again.
Any ideas on how to break the chain here are welcome.
