This may be a stupid question but I can't find an easy answer for what I
want to do. I need a blob data field that can store both binary and text
data like the sql_variant field. I am using vb.net to populate a sql table.
I want to store both string and binary data.
i need to store a bmp or zipped file in a field of a ms sql db. i read the file using vb6 o.net, and in my mind i think sto store it in binary mode. the files could be more of 12 mega. whitch kind of field a could use?
View 1 Replies View RelatedHi. how can i store binary data to another field with image data types.
here is my sample code

I want to store Images as binary data in SQL table and compare it each time with a image file I am getting. I've tried below approach but getting error:
DROP TABLE #BLOBTest
CREATE TABLE #BLOBTest
(
TestID int IDENTITY(1,1),
BLOBName varChar(50),
BLOBData varBinary(MAX)
);
[Code] ....
Error: Msg 4861, Level 16, State 1, Line 10
Cannot bulk load because the file "C:Files12656.jpg" could not be opened. Operating system error code 3(failed to retrieve text for this error. Reason: 15105).
Application is ocr'ing tiff image files and then storing the resultant text data in a text field in SQL 2005 database. This field is then used with the full text catalog.
All works fine,
However, am I using the correct field type to store the text files for efficiency and space saving?
If I use a binary field, does this reduce the size of the database by compressing the text data in the binary field? Also, is there a limit as to the size of text file that I could store in a binary field?
It would be good to get feedback on this before I go too far down the wrong road.
So, text field to store the text data or binary field to store the actual text file?
hello dear friends
I am trying to save a binary file to database with the following code:
public static void memorystreamToDb()
{
MemoryStream mst = new MemoryStream();
UnicodeEncoding u = new UnicodeEncoding();
string Textn = "Test";
byte[] b = u.GetBytes(Textn);
mst.Write(b ,0,Textn.Length );
BinaryReader reader = new BinaryReader(mst);
byte[] file = reader.ReadBytes((int)mst.Length);
using (SqlConnection connection = new SqlConnection("Some Connection String"))
{
SqlCommand command = new SqlCommand("INSERT INTO temp (examplefile) Values(@File)", connection);
command.Parameters.Add("@File", SqlDbType.Binary, file.Length).Value = file;
connection.Open();
command.ExecuteNonQuery();
}
reader.Close();
mst.Close();
}
or with the other method from a real file (not memory stream)
public static void Addfile(string path)
{
CommonMethods_class k = new CommonMethods_class();
byte[] file = GetFile(path);
using (SqlConnection connection = new SqlConnection(k.Get_connection_string()))
{
SqlCommand command = new SqlCommand("INSERT INTO temp (examplefile) Values(@File)", connection);
command.Parameters.Add("@File", SqlDbType.Binary, file.Length).Value = file;
connection.Open();
command.ExecuteNonQuery();
}
}
and after running each of them seams that the file have been saved; but I can not retrive the files. I have tried some solutions from msdn but inside the created file is empty. the point that i really look for it is to just working with memory not in the disk before saving. and then retriving each field that I want.
looking forward your points
thank you in advance

Is there any way to store a binary or image file into a database record / save a binary or image record back into a file using Transact SQL? If yes, would the "image" data type be most suitable?
(As a background, I am working on a process that deals with incomign emails, and I am using SQL Mail for that purpose. The above is needed to deal with attachments that may come with emails, and which are saved in a physical file on the HDD).
Thanks a lot in advance...

View 3 Replies View RelatedHi 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!

Hey everyone,
I'm deploying a desktop application with Sql CE 3.5. I have a collection of files that I would like to be save as a binary format in SQL CE. These files range from 1KB to 5MB. I know I cannot use varbinary(max) , instead I am limited to varbinary(8000), but this obvisously comes short of 5MB. There are articles stating to use the image datatype to get around this. Is this just bad practice, should I keep the files on the file system or take advantage of this work around? Do you have any suggestions?
Thanks in advance,

View 1 Replies View RelatedHello there,I just want to ask if storing data in dbase is much better than storing it in the file system? Because for one, i am currenlty developing my thesis which uploads a blob.doc file to a web server (currently i'm using the localhost of ASP.NET) then retrieves it from the local hostAlso i want to know if im right at this, the localhost of ASP.NET is the same as the one of a natural web server on the net? Because i'm just thinking of uploading and downloading the files from a web server. Although our thesis defense didn't require us to really upload it on the net, we were advised to use a localhost on our PC's. I'll be just using my local server Is it ok to just use a web server for storing files than a database?

The problem field is of type ntext, and the length is 16. We've tried changing it to varchar of length of 8000, and this didn't help either. Text datatype didn't work either.When the user pastes a word document or enters more than 11 lines of text, the field in the database goes plank.Here's the subroutine for the Insert.

Hello,
I have an Excel spreadsheet that contains 100,000 + rows of data. Two of the columns in the spreadsheet are date fields that are sent over in the yyyymmdd format (no separators such as "-" or "/"). I tried converting these fields into dates using the Data Conversion task in SSIS. This doesn't work as it appears that SSIS cannot map a string in the format of yyyymmdd to a valid date. In lieu of this, I have added a Script Component to my transformation which can take the string and convert it to a date value using some Substring() calls on the source yyyymmdd string.
A few questions for the group ...
1. Is this there a more efficient or "better" way of performing this transformation?
2. I can also use OLE DB Command task in my transformation and make a call that might do something like this: select convert(datetime, convert(varchar(10), [@yyyymmddValue])) but how would this perform related to the Script Component task? My guess is that this would be slower since the transformation would make a database call for every record.
3. Are there any plans for the SQL team to make these types of conversions easier to implement in the future? It seems to me that this is a pretty common scenario for integrating date data.
Thanks!

how can i insert a carriage return when i update the field?
say i want to put the following inside a field:
firstline
secondline
how can i update/insert a column to have a return carriage inside it?
UPDATE table SET column = 'firstline secondline'
the reason i want this is because when using a program (Solomon, by microsoft, purchasing software) to grab a field out of the database and when it displays that field in the programs textbox, i want it to be displayed on two separate lines
i tried doing
UPDATE table SET column = 'firstline' + char(13) 'secondline'
but when in the solomon program, it displays an ascii character between firstline and secondline like: firstline||secondline
thanks

View 1 Replies View RelatedHi,
I have asked this question on 3 forums now and never get an answer, I don't know what is so hard about this question but I will try it here.
I am using SHA512 in C# to convert a password and its salt to hashed. I need to store the password hash and the salt hash in the database in two fields. I was told to use binary field to store the hash data and that the output of SHA512 would ALWAYS be the same no matter how long the password is.
I modified this hash example to use only SHA512 and to work with byte array instead of plain text.
All I need to know now is what size I need to make my binary field to hold this password that is hashed.
http://www.obviex.com/samples/Code.aspx?Source=HashCS&Title=Hashing%20Data&Lang=C%23
Say I have a password which is 30 characters max, and a salt which is 16 characters max. The password and the hash are stored in seperate fields in the same table. They are both hashed using SHA512 and are both being stored as byte arrays in C#, what size to I need to make the binary data type in order to hold the password, and to hold the salt.
Thanks!

Can anyone point me in the right direction to find documentation for the problem below?I need to store and retrieve ten fields of 16-bits each for testing 16 true-false conditions (a total of 160 bits in each record) so I think I'd like to use ten 2-byte binary fields (160 "bit" fields would be quite unmanageble, if even possible [I think there is some kind of limit to the number of fields in a single record]). I'm not quickly finding in the SQL Server's online documentation how to test for, use and update binary fields. I'll keep looking, but can anyone point me in the right direction? I'm using VB, if that makes any difference.
