Answer 1

Try to use parameterized query

conn.Open();
string query = "SELECT * FROM " + TableName + " WHERE [TIME_STAMP] =@date "
+" AND [Slave_Id]=@sid AND [Parameter] =@param  "
+" AND [Status] =@status AND [Reading] = @reading"
qlCommand cmd = new SqlCommand(query,conn);
cmd.Parameters.AddWithValue("@date", TimeStamp);
cmd.Parameters.AddWithValue("@sid", SlaveUnitID);
cmd.Parameters.AddWithValue("@param", Param);
cmd.Parameters.AddWithValue("@status", Status);
cmd.Parameters.AddWithValue("@reading", Reading );
dr = cmd.ExecuteReader();
