Hello,
I have a database I would like to know how to locate the FILESTREAM data
For a row in a table I want the physical location:
D:\Test_FSss\e0b4921f-8cb2-49c1-b4e7-f01a7376cac1
I tried patshname function but it does not give me the desired result.
Thank you in advance.

This sort of information is internal to the database and will be dependent on the type of database system.

there is no one thing is very important for my project.
|
|
|
|
|
Even if this is very important for your project, the fact is, for all the major database vendors there is no API call that will give you this information.
|
|
|
|
|
|
There is no need for anyone to know this information. Perhaps your question is not clear, please explain what you are trying to achieve.

I have a Cust table that exceeds 10T partitioned over several Filegroup, Filestream and includes the information of customers, my boss asked me to locate him physical location to make archiving and backup by another application
I hope to be clear.
thank you.

This is a Database issue and nothing to do with .NET. You should be talking to your Database administrator, or the company that produces the database. Also, you should use the Database administration tools for backup.

Err no. That's nothing to do with the question that was asked.
|
|
|
|
|
Why? Because "ImageSaveInDataBase.zip" doesn't exist on the CodeProject server?
|
|
|
|
|
No, because saving and retrieving an image from a database has absolutely nothing to do with getting the names of database filestreams.
|
|
|
|
|
No. It's not the answer because the OP is asking how to open up database filestreams.

What is the problem?
Is something happening that shouldn't?
does it error? if so what is the error message?

The code i posted works fine. But i need to use SQL instead of Access.
And i am not an expert in SQL.
So , if possible, can you tell me what to change and how in order to use SQL instead of Access?

I started by doing this:
imports system.data.sqlClient
Public Sub Form1
Dim _DataAdapter As New SqlDataAdapter
Dim _CommandBuilder As SqlCommandBuilder
Dim _DataSet As New DataSet
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim _cnstring As String = "Data Source=Eliane-VAIO\SQLEXPRESS;Initial catalog=ADOnet;Integrated Security=True;"
Dim _cn As New SqlConnection(_cnstring)
Dim _cmd As New SqlCommand("select * from tblCutomer", _cn)
_cn.Open()
Dim reader As SqlDataReader = _cmd.ExecuteReader()
Try
_DataAdapter.Fill(_DataSet)
Catch eror As Exception
MsgBox(eror.Message)
End Try
End Sub
But i am feeling a bit lost. And an error occurs:
the select command property has not been initialized before calling "Fill".

assuming you are using SQL Server I would have a read of these
ADO.NET Code examples[^]
connectionstrings[^]
but a simple example would be as follows
string Query = "select * from someTable where id = @id";
using(SqlConnection dbase = new SqlConnection("ConnectionString"))
{
dbase.Open();
SqlCommand cmd = new SqlCommand(Query, dbase);
cmd.Parameters.AddWithValue(@id, 10);
SqlDataReader rdr = cmd.ExecuteReader();
if(rdr.HasRows)
{
while(rdr.Read())
{
}
}
}
if you want to use datatables its very similar
string Query = "select * from someTable where id = @id";
DataTable dt = new DataTable();
using(SqlConnection dbase = new SqlConnection("ConnectionString"))
{
dbase.Open();
SqlCommand cmd = new SqlCommand(Query, dbase);
cmd.Parameters.AddWithValue(@id, 10);
dt.Load(cmd.ExecuteReader());
}
hope this helps you start to convert your rountine to work with SQL Server

Thank you for your help. I am new to SQL
I am trying to assemble the code. It's a bit hard for me, since it's my first time with SQL.
If you can assemble the code for me I will be more than thankfull 
Thanks again.

I am afraid to say that I wont write your code for as how would you learn if I did it for you. I have given links to examples on the web that will help you learn what you are after doing.

Nobody is going to do your work for you. We all have our own code to write.
The conversion from Access to SQL is rather simple. Wherever you have "OleDb..." you replace with "Sql". That includes OleDbConnection, ...Command, DataReader, ...
