I tried the following but it fails on the line 7.

How can I write the data from sql to my computer?

Here is my table in sql:

[AttachType] [nvarchar](255) COLLATE Hebrew_CI_AS NULL,

[AttachSize] [int] NOT NULL DEFAULT (0),

[AttachCompSize] [int] NOT NULL DEFAULT (0),[AttachData] [image] NOT NULL

) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]1 Dim s As New _
2 System.IO.FileStream("c:emails" _

Backup Master Key, Cannot Write Into File 'c: Empmaster'. Verify That You Have Write Permissions, That The File Path Is Valid.

Jul 12, 2006

Hi,



I tried to backup the master key by the following syntax :

OPEN MASTER KEY DECRYPTION BY PASSWORD = 'mypassword'

BACKUP MASTER KEY TO FILE = 'c: empmaster' ENCRYPTION BY PASSWORD = 'mypassword'

but it failed and i got the following message:

Cannot write into file 'c: empmaster'. Verify that you have write permissions, that the file path is valid, and that the file does not already exist.

NB: I am using the "sa" user to execute this command.

I know that we have a security permission issue , but where and how ?

Dtsconfig File Is Binary?

Feb 16, 2006

Hello all,

I'm trying to easily change a value in 80 ssis configuration files from "localhost" to "myservername". I downloaded WinGrep to do this, but it's balking on some of the files, saying that they are binary files.

Does anyone know how to make the *.dtsconfig files NOT binary in SSIS?

Any suggestions GREATLY appreciated.

I won't go into the reason I have my servername in 80 places...

Import From Binary File

Feb 17, 2006

I am importing data from binary data files into SQL Server. This is the code I am using:

Do While Not EOF(1)
Get #1, , NonStdCurrRecord
adoRS.AddNew
adoRS!Field1 = CDate(NonStdCurrRecord.Field1)
adoRS!Field2 = CSng(NonStdCurrRecord.Field2)
adoRS!Field3 = CSng(NonStdCurrRecord.Field3)
adoRS!Field4 = CSng(NonStdCurrRecord.Field4)
adoRS!Field5 = CSng(NonStdCurrRecord.Field5)
adoRS!Field6 = CSng(NonStdCurrRecord.Field6)
adoRS!Field7 = CSng(NonStdCurrRecord.Field7)
adoRS.Update
Loop


Unfortunately, it takes about 8 mins to import a file with 180k records. Is there a faster way to do this?

Retrive A File From A Binary Data Field

Nov 6, 2006

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

String Or Binary Data Would Be Truncated (from Xml File)

Apr 13, 2005

Hello all,
I am exporting data from AS/400 into an xml file and then importing the data from the xml file into an SQL database. I am getting the error: "The statement has been terminated. String or binary data would be truncated" when there are characters like "," or "&" in the xml. How can i solve this problem? Almost all my records have characters like that because they include comments and i can't disallow the users from entering these characters (especially ",").

How To Store File Attachments (text And Binary).

Nov 9, 2006

I need to store several different types of documents (text, MS Word, PDF, etc.) in SQL Server 2005. What is the best way to store file attachments that have different MIME types?

Currently I'm using a table with a varbinary(max) column which works for binary files but not for text files. Do I need to have multiple columns in the table for different file types? Thanks in advance for your help.


CREATE TABLE dbo.[CM_Attachment] (
[Id] int IDENTITY (1, 1) NOT NULL ,
[Change_Request_Id] int NOT NULL ,
[Attachment] varbinary(max) not null,
[Created_Date] datetime NOT NULL DEFAULT GetDate() ,
[Created_By] varchar(30) NOT NULL ,
[Modified_Date] datetime NOT NULL ,
[Modified_By] varchar(30) NOT NULL
)
GO


INSERT INTO CM_Attachment(Change_Request_Id, Attachment, Created_By, Modified_Date, Modified_By)
SELECT 6, BulkColumn , '', GetDate(), ''
FROM Openrowset( Bulk 'C:TestingTest Doc #1.txt', SINGLE_CLOB) -- Does not work
-- FROM Openrowset( Bulk 'C:TestingTest Doc #2.xls', Single_Blob) -- Works
-- FROM Openrowset( Bulk 'C:TestingTest Doc #3.jpg', Single_Blob) -- Works

Binary Column Or Flat File Best Practices?

Jul 17, 2007

I have a design oriented question for a system I am developing. Because of various business concerns and issues we have been moving towards as desing that brings files into the SQL 2005 system as binary columns in a database. These files will then be processed at a later time using SSIS into relation model tables.



Normally I would just have the process be files are placed on a FTP location (or other drive path) and a location is stored in the database versus the storing of them as binary rows in the database. Then later the SSIS package runs using the path information for the conneciton manager.



Based on the proposed binary design I have two questions.

1. Can anyone speak to the advantages, disadvantages, issues they have had, etc to the binary storage method?

2. Can anyone make a suggestion on how they would handle the pulling of the file out of SQL when the file is ready to process? Do you stream it to a file and rebuild it on the physical disk, to then just import it with a connection manager for the flat file structure.... or can you stream it directly into a conneciton manager that reads it like a flat file and parses the file without ever going to disk? Any information on suggested implementations would be helpful.



Thanks.

Using The File Connection Manager To Write To A File

Jan 7, 2008

Is there any real purpose to the File Connection Manager? Not the Flat File Connection Manager, just the plain old File Connection Manager.

I have one in my SSIS package because I thought it might make writing to a file easier. But from what I can tell, it doesn't really do much. I have to pull the file name from the connection manager and basically open and manage the file myself in my scripts.

I went this route because I have two scripts that write to the file in turn... one writing out parent records and the other inserting the child records after each parent.

The script looks like this:




Code Block
Dim outFile As String
outFile = Dts.Connections("TestFile.LDIF").AcquireConnection(Dts.Transaction).ToString()

Dim sw As New StreamWriter(outFile, True)
sw.WriteLine()
sw.WriteLine("dn: " & Dts.Variables("GroupID").Value.ToString())
sw.WriteLine("changeType: add")

sw.Close()

I have to close the connection every time because the other script uses the file. It seems that this is quite inefficient. Am I using the File Connection Manager incorrectly? What's a more appropriate way to do this?

I could open the file in a different script and store the StreamWriter object in a global variable, I suppose...

Thoughts, suggestions?

Thanks.

J

Writing Binary Data To Database Only To Refrence A File Location?

Sep 29, 2006

Hey everyone I've got this question that has me stuck for the last few days but its an important part of my website.....What I am trying to do is basicly have a user be able to upload a file, have that uploaded file plus some other info automaticly display on other parts of my site, and have a different user eventually be able to download that file....I have thought about allowing the file upload as a BLOB but still cannot find a proper way to execute this using VB, plus I have heard that this way of doing it is not reccommeneded cause databases were not designed to store large files like this, lots of articles recommened having the file upload to a Folder on your server then get the binary data for the file that can be placed in a database to refrence that particular file.....Well this also proves to be a lot harder then said here is what I got so far (written in C#) protected void UploadBtn_Click(object sender, EventArgs e)
{
if (FileUpLoad1.HasFile)
{

FileUpLoad1.SaveAs(@"C:Documents and SettingsAdamMy DocumentsVisual Studio 2005ProjectsWebsiteFiles" + FileUpLoad1.FileName);
Label1.Text = "File Uploaded: " + FileUpLoad1.FileName;
}
else
{
Label1.Text = "No File Uploaded.";
}
}
and here is the asp part of the code that goes with it<asp:FileUpLoad id="FileUpLoad1" runat="server" />

<asp:Button id="UploadBtn" Text="Upload File" OnClick="UploadBtn_Click" runat="server" Width="105px" />

<asp:Label ID="Label1" runat="server" Text=""></asp:Label>
 Now from what I know is I need to get the binary of the file which I have read you can do with the Page.Request.Files statement but again not sure how I would impliment this.  Does anyone have any suggestions on which way I should take when dealing with this should I try and just use the BLOB method or use the binary refrence method? and if so how would I impliment this, heck even some good tutorials on the subject would be great... Thanks.....Adam

Concatenate All Binary Columns Into Single Binary Column?

May 22, 2014

Server is SQL 2000

I have a table with 10 rows with a varbinary column

I wish to concatenate all the binary column into a single binary column and then write that to another table within the database. This application splits a binary file (Word or PDF document) into multiple segments (this is Column2 as below)

example as follows

TableA

Column1 Column2 Column3
aaa 001 <some binary value>
aaa 002 <some binary value>
aaa 003 <some binary value>
aaa 004 <some binary value>
aaa 005 <some binary value>

desired results in TableB

Column1 Column2
aaa <concatenated value of above binary columns>

SQL Server 2008 :: Large Binary Dataset - Database Or File System?

Jun 2, 2015

I have a well-structured but also very large binary data-set that is generated by a C++ application every five minutes. The data needs to be accessed by SQL applications. Since data is generated every five minutes, performance is key, both for write and read. The data set is about 500MB.If data is written to the file system, the write performance doesn't involve SQL server. For reading it, I have a CLR to read the portions of the data that I need based on offset and length. That works and is very fast. The problem is that data is stored in the file system, so it is not self-contained within the database.

A second option that I haven't explored yet, is to write the data into a table as VARBINARY(MAX). I would read the data using SUBSTRING with appropriate offset and length. Performance of SQL write/read of binary data of this size, and whether there is a third option I haven't thought off. I'm using SQL Server 2014.
