Question

I want to know how to create an image column in a SQL Server table and retrieve it in ASP.NET using VB.NET

create table Tbl(ID int primary key,Name varchar(20),Image ....)

Answer 1

You want to use the VARBINARY(MAX) to store this data.

As to the code side, here is a good, brief answer.

From the answer:

FileStream st = new FileStream(@"C:\filename.jpg", FileMode.Open);
byte[] buffer = new byte[st.Length];
st.Read(buffer, 0, (int)st.Length);
st.Close();

SqlConnection conn = new SqlConnection("...");
SqlCommand cmd = new SqlCommand(
    "UPDATE SomeTable SET image=@image WHERE ID = 1", conn);
cmd.Parameters.AddWithValue("@image", buffer);
conn.Open();
int i = cmd.ExecuteNonQuery();
conn.Close();
