Hi I've followed a tutorial on how to write and read varbinary(max) data to and from a database. But when i try to read the data i get the error that the data would be truncated, but only when the varbinary(max) is greater then 8kB. I've used a system stored procedure (sp_tableoption) to set the table that holds the data to store data outside rows. To select the data i'm using a stored procedure: SELECT imageData , MIMEType FROM Pictures WHERE (imageTitle = @imageTitle) And then using an .aspx page to Response.Write the data:Using conn As New sql.SqlConnection conn.ConnectionString = ConfigurationManager.ConnectionStrings("myConnectionString").ToString Dim getLogoCommand As New sql.SqlCommand getLogoCommand.CommandType = Data.CommandType.StoredProcedure getLogoCommand.CommandText = "GetPicture" getLogoCommand.Connection = conn Dim imageTitleParameter As New sql.SqlParameter("@imageTitle", Data.SqlDbType.NVarChar, 200) imageTitleParameter.Value = Request("imageTitle") imageTitleParameter.Direction = Data.ParameterDirection.Input getLogoCommand.Parameters.Add(imageTitleParameter) conn.Open() Using logoReader As sql.SqlDataReader = getLogoCommand.ExecuteReader logoReader.Read() If logoReader.HasRows = True Then Response.Clear() Response.ContentType = logoReader("MIMEtype").ToString() Response.BinaryWrite(logoReader("imageData")) End If End Using conn.Close() End Using Can anyone please help me with this?!
I am developing a simple ASP based form, that stores user info in MS SQL server. I have created a table in the SQL server to store the data and defined the body field with this line: `body char(255)`. The problem is that if the user inputs a string longer then 255 characters it gets choped off. How would you suggest solving this problem? Should I use `text` datatype instead?? Any comments are very appreciated !!!

I want to read certain data from the backup file of MS SQL 2000 without restoring the database backup file. Based on the data selected I will manage the further functionality such as restoration of the backup file. Is it possible to read some data from MS SQL 2000 backup file without restoring? If yes then please let me know how?
We have a set of databases some are fully read-only others have read-only file groups, is there any way to restore backups of these taken on an MSDE 2000 to an SQL Express 2005 instance?
When doing the inplace upgrade we change these to read-write before the upgrade and set them back after the upgrade.
These databases are used in the field by customers althought the controlled upgrade requires a backup before (and blocks if it fails) and tries a backup after if the post upgrade backup fails (due to disk space) we might need to recover from this odd situation.
The only solution I have is install MSDE some place restore to this then do the controlled upgrade again, any other ideas?
Could someone please point me in the right direction on how to read ina large query with .net.I am trying to emulate a legacy database system so I don't know theupper bounds of the sql query. An example query would be somethinglike:Select * from invoices where year 1995the query must be updatable and only return say 10 to 100 rows at atime.It should also be forward only and discard rows no longer in use tosave memory.And if at all possible I would like to lock one row at a time as therow is read in.
Hi, I have an issue with an application, and i want to know what sql queries are done by this application. So i need to read the .ldf file, i have do some search on google, but i find nothing thant can be relevant.
I have some problems with our database which is growing too large, and was hoping someone might have some tips on what I can do!
I have about 100 clients, each logging about 10 000 rows of status logs a day. So after just a few days the db is growing very large.
At present it's manageable, since I don't need to "dig" into the logs more than a few times a day. The system it self is not affected by the size of the log or traffic on the server. But it will increase to about 500 clients in 2004, and 1000-1500 in 2005. So I really need a smarter solution than what I have today to be able to use the log efficiently.
98-99% of these rows are status-messages which are more or less garbage during normal operation. But I still need to keep them in case an error occurs, and we need to go back an hour or two (maybe a day) to see what went wrong. After 24-48 hours these 98-99% are of no use. I do however like to keep the remaining 1-2%, they are messages like startup, errors, etc. Ideally they should be logged in two separate tables by the clients, but unfortunatelly I cannot make the clients change their logging.
This presents problems on multiple levels. Mainly in searching, which often times out, but also with backup and storagespace. At the moment I check the system for errors, and every other day I just truncate the log-file. It works, but it's not exacly elegant......
The server is a 1100 MHz P3 / 512MB / Windows 2000 Server / SQL Server 2000. Faster hardware would help, but the problem is more of a "bad design" than "slow hardware" problem.
My log is pretty simple, as follows:
LogId - int - primary key - clustered index ClientId - int - index asc LogTypeId - int - index asc LogValue - nvarchar[2500], ikke index LogTimeStamp- datetime - index asc
I have deducted 3 different solutions:
Method 1: Simply run "Delete from db_log where logtyipeid <> stuff_I_want_to_keep".
This is the simplest and the one i prefer, but it takes too long time to complete. Any tips to speed this process up?
Method 2: Create a trigger which runs something like "Delete from db_log where logtypeid <> stuff_I_want_to_keep and date < today_minus_two_days" every hour or so. This will ensure that the db doesn't grow to large. But if I'm away from work a few days we might loose data we'd wanted to keep.
Method 3:
Copy what I want to keep into another table, and empty the log. Sort of like "Insert into db_log_keep stuff_to_keep; drop db_log; create table db_log; " (or truncate, but that takes a long time too)
But then I would be stuck with two log tables, "48-hour_db_log" and "db_log_keep". I could use a view to "union" them so they would appear as a single table, but that's not ideal either.
However, it seems as this method is what will work best for my set-up, unless there are other suggestions??
Method 4:
...eagerly awaiting ideas!!! :-)
(Also, whatever tips and/or links to info on maintaing VLDB's are greatly appreciated. )
I'm in the process of migrating a lot of data (millions of rows, 4GB+of data) from an older SQL Server 7.0 database to a new SQL Server2000 machine.Time is not of the essence; my main concern during the migration isthat when I copy in the new data, the new database isn't paralyzed bythe amount of bulk copying being one. For this reason, I'm splittingthe data into one-month chunks (the data's all timestamped and goesback about 3 years), exporting as CSV, compressing the files, and thenimporting them on the target server. The reason I'm using CSV isbecause we may want to also copy this data to other non-SQL Serversystems later, and CSV is pretty universal. I'm also copying in thisformat because the target server is remotely hosted and is notaccessible by any method except FTP and Remote Desktop -- nodatabase-to-database copying allowed for security reasons.My questions:1) Given all of this, what would be the least intrusive way to copyover all this data? The target server has to remain running and berelatively uninterrupted. One of the issues that goes hand-in-handwith this is indexes: should I copy over all the data first and thencreate indexes, or allow SQL Server to rebuild indexes as I go?2) Another option is to make a SQL Server backup of the database fromthe old server, upload it, mount it, and then copy over the data. I'mworried that this would slow operations down to a crawl, though, whichis why I'm taking the piecemeal approach.Comments, suggestions, raw fish?
From what I can see, the 'varbinary(max)' data type is not supported, and the 'image' data type is supposed to go away. Is there some other way to store large chunks (10MB to 100MB) of data into an SSEv DB?
If I have to use the 'image' data type to so this, does anyone have a code sample that would let me push an array() of numbers into an 'image' field, and unload an 'image' field into an array()?
I'm running a resource-intensive stored procedure, which reads a filewith about 50,000 lines with a BULK INSERT into a temp table, thengoes through it and inserts a record for each line into another table.While this procedure is running, SQL server stops accepting any otherrequests coming from the website.Question:Is there a way to make SQL server "listen", or emulate an "interrupt"to other requests while in the middle of a long intensive process?I really appreciate your replies.Thank you,Oleg.
Hi all,I am doing some large updates,that may update 10,000 plus rows.This works fine when I execute the SQL directlyin Query Analyzer.If I set the timeout on my VB connection to 0 (zero)the connection should not time out????But it does.If I set the time out to a high value, say 1200,I get the same problem well within 1200 seconds.Also, I am getting the problem that the log fills up,but it is set to auto grow????Any ideas would be appreciated.ThanksGreg

I'm trying to upgrade from SQL Server 2000 to 2005. The problem I am having is that when I try to attach the existing db files I get a message that says "database cannot be upgraded because it is read only or has read only files...."
Thing is... there is no write protection on the files.
Can anyone advise me on how to overcome this problem so that I can attach the db, please?
if it is possible to run a distributed query against 2000 from 2005, what would the OPENDATASOURCE parameters look like? I'd like to be able to pivot without copying my older 2000 db to 2005 or using linked servers..
For reference, here's an example of a distrib query that reads excel...
ie SELECT * INTO XLImport3 FROM OPENDATASOURCE('Microsoft.Jet.OLEDB.4.0', 'Data Source=C: estxltest.xls;Extended Properties=Excel 8.0')...[Customers$]
Hi everybody, On executing the RESTORE command of SQL Server to restore from a backup of 78.3 MB, the "Server Application Unavailable" error message comes up.The error message in the Application log is as follows:aspnet_wp.exe (PID: 2184) was recycled because memory consumption exceeded the 152 MB (60 percent of available RAM). However using Query Analyser of SQL Server I am able to restore the database. What is the solution to this problem?
