SQLパフォーマンス、実行プランのほとんどがインデックスの代わりにインデックススキャンを表示します。シーク

Question

私は以下のクエリを実行しています。これは主に25レコードを返します。しかし、それは約20秒かかる。また、テーブル内のレコードの総数は400,000未満です。以下は

SELECT * FROM Tickets 
LEFT OUTER JOIN HouseAccounts ON (Tickets.lHouseAccount_ID = HouseAccounts.lAccountID) 
LEFT OUTER JOIN Customers ON (Tickets.lCustomerID = Customers.lCustomerID) 
LEFT OUTER JOIN Vehicles ON (Tickets.lVehicleID = Vehicles.lVehicleID) 
WHERE (Tickets.sTicket_Number) NOT LIKE 'ADJ%' AND dbo.DateOnly(Tickets.dtCreated) between DATEADD(day, -60, dbo.DateOnly(GETDATE())) 
and dbo.DateOnly(GETDATE()) AND (Tickets.bDeleted = 0 or Tickets.bDeleted IS NULL)

Answer 1

可能な場合、彼らは遅いので、あなたは、スカラーと複数ステートメントのUDFを避ける必要があります。そして、あなたは絶対に避けなければなりません。 dbo.DateOnly(をConvert(date,に置き換えると役立ちます。

私が興味があるのは、将来のチケットはありますか？そしてもしあれば、あなたは本当にそれらをスキップしたいですか？チャンスは、betweenを簡単にTickets.dtCreated >= convert(date, DATEADD(day, -60, GETDATE()))に置き換えることができます。
