Question

My code times out on the ExecuteNonQuery line below. I don’t know why. I’ve increased the timeout to 900 and it still times out.

using (var conn = new SqlConnection(localConnection))

        {
            var command = String.Format(@"UPDATE dbo.Documents SET DocFile = {0} WHERE ID = '{1}'", @"BulkColumn from Openrowset(Bulk 'C:\Work\Document.docx', Single_Blob) AS DocFile", projID);
            using (var sqlWrite = new SqlCommand(command, conn))
            {
                conn.Open();
                sqlWrite.Parameters.Add("@File", SqlDbType.VarBinary, file.Length).Value = file;
                sqlWrite.ExecuteNonQuery();
            }
        }

Since this is a bulk activity, which I imagine is updating many many rows, it’s probably legitimately taking that long. Try setting the timeout to 0 for “No timeout” and see if it will complete.
