I want to store a binary string in SqlServer from VB .NET through a
stored procedure. I have been storing the binary data in a BitArray
which I am not set on by any means. When I pass the BitArray into a
stored procedure, which is looking for a variable of type binary, it
throws the following: "Object must implement IConvertible." BitArray
obviously does not implement IConvertable.
If anyone has a good way of passing binary data into a stored
procedure through a parameter array I'd appreciate it.
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)
I'm using a bit-wise comparison to effectively store multiple values in one column. However once the number of values increases it starts to become too big for a int data type.you also cannot perform a bitwise & on two binary datatypes. Is there a better way to store the binary data rather than int or binary?
i am using asp.net 2.0 with c#. i have database - mssql server. in that i have tuser table in that table i have password feild which datatype is Binary. when i am entered password in asp.net application that time runtime error is convert the string to binary. my code is---string myByte = Stingtest; System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();Byte[] bytes = encoding.GetBytes(myByte);myByte = ""; myByte = encoding.GetString(bytes);
Hello,I am trying to serialize (binary) a class and save it in a database. I followed a few examples I found in internet and this is what I came up with: 1 ' Rows 2 <Serializable()> _ 3 Public Class Rows 4 Implements ISerializable 5 6 Private _Rows As New Generic.List(Of Row) 7 Public Property Rows() As Generic.List(Of Row) 8 Get 9 Return _Rows 10 End Get 11 Set(ByVal value As Generic.List(Of Row)) 12 _Rows = value 13 End Set 14 End Property ' Rows 15 16 ' New 17 Public Sub New() 18 End Sub ' New 19 20 ' New 21 Public Sub New(ByVal siRows As SerializationInfo, ByVal scRows As StreamingContext) 22 End Sub ' New 23 24 ' GetObjectData 25 Public Sub GetObjectData(ByVal siRows As SerializationInfo, ByVal scRows As StreamingContext) Implements ISerializable.GetObjectData 26 27 siRows.AddValue("Rows", Me.Rows) 28 29 End Sub ' GetObjectData 30 31 Public Sub Serialize(ByVal filename As String) 32 33 Dim sRows As Stream = Stream.Null 34 Try 35 sRows = File.Open(filename, FileMode.Create, FileAccess.ReadWrite) 36 Dim bfRows As New BinaryFormatter 37 bfRows.Serialize(sRows, Me) 38 Finally 39 sRows.Close() 40 End Try 41 42 End Sub ' Serialize 43 44 Public Shared Function Deserialize(ByVal filename As String) As Rows 45 46 Dim sRows As Stream = Stream.Null 47 Try 48 sRows = File.Open(filename, FileMode.Open, FileAccess.Read) 49 Dim bfRows As New BinaryFormatter 50 Return CType(bfRows.Deserialize(sRows), Rows) 51 Finally 52 sRows.Close() 53 End Try 54 55 End Function ' Deserialize 56 57 End Class ' Rows After serializing the class I need to save it in an a SQL 2005 database.But all the examples I followed use the filename ... Anyway, do I need to do something to save this into an SQL 2005 database or can I use it as follows? And how can I use this?This is the first time I do something like this so I am a little bit confused.Thanks,Miguel

Hello, I have a table which uses binary data to store passwords. How do I view the contents of the "binary data" column, ie. the passwords? It just shows it as <binary data>?
I have a binary column with length 20 in SQL server table. I store dynamically C# byte[] value range from 0 to 19. So for example, If I store length of 16 and when I try to retrive it back into byte [] in C# it returns whole length 20. When I see in debug it has value from 0 to 15 which I want to use but from 16 to 19 is zero. How can I get just length value which I stored.
I use DataRow to get whole row and from the row object I extract byte [] based on column name.

Quick question here. I am working with a database which uses Binary(8) as an id(ie, contact_id is binary(8), and connects 2 tables). I can already extract the binary data (in the form 00-00-00-00-00-00-ab-cd). I know that there exists a contact_id 0x0000000000001989 (hex) however, when I attempt this query...
"SELECT * FROM Support_Incident where Contact_Id = '0x0000000000001989'". I get no results. What have I done wrong?
I would like to drop the leading 0x on a binary value so I can do abitwise operation.Here is simplified code:select right(0x88186000,8)I expected to get back 88186000, this was not the case. The commandreturned some wierd characters.Am I missing something?

Hello All, I am using a stored procedure.

I am trying to store a byte array in a database. I want to use binary to store the data but I am confused about the type. The byte array I am trying to store is a password hash from SHA512. I hash a plain text value then store the result in a byte array. I then want to store the byte array in the database as binary but I am confused when its asking for the size of the binary field. In nvarchar a size of 2 would mean 2 characters. How should I choose the size of this binary field, and what does the size mean. If I choose a size of 6 does that mean 6 characters, like 010110. Or is it stored differently? The maximum size of a plain text password is 30 characters, and the salt used to generate the SHA512 hash has a maximum size of 16, but I don't know the exact size of the salt because its randomly picked when the salt is generated. I need to make sure the size of my binary field will hold the largest possible password hash, but I don't want it too large so its never completely used. How is this data stored in the binary field, and what size binary field should I choose to make sure there are no problems with the password hash being truncated, yet making sure I'm not just wasting by creating a field thats too large. Thanks!

In MSDB, all job_ID are uniqueidentifier data type, sometimes Job_ID is binary datatype. I need to print 'job_ID: ' + cast(@job_ID as varchar(100)). It prints nothing...
How could I convert and print the contents of Job_ID?
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?
