data.MakeInParam("@info",SqlDbType.VarChar,50,info),
data.MakeInPa

int i = 0;
SqlCommand cmd = new SqlCommand(sql, conn);
if (sp != null)
{
foreach (SqlParameter parm in sp)

cmd.Parameters.Add(parm);
}
}
cmd.CommandType = commandType;
conn.Open();
try
{
i=cmd.ExecuteNonQuery();
}
catch (SqlException ex)
