GROUP BY status

Code:

sqlite.Select(
  sm.Columns("status", sqlite.F("avg", "difference")),
  sm.From(sqlite.Select(
    sm.Columns(
      "status",

        fm.Over().PartitionBy("presale_id").OrderBy("created_date"),
      ).Minus(sqlite.Quote("created_date")).As("difference")),
    sm.From("presales_presalestatus")),
  ).As("differnce_by_status"),
  sm.Where(sqlite.Quote("status").In(sqlite.S("A"), sqlite.S("B"), sqlite.S("C"))),

    sm.Where(sqlite.Quote("client_id").EQ(sqlite.Arg("123"))),
  )).As("clients"),
  sm.Where(sqlite.Quote("id").EQ(sqlite.Arg(100))),
)
