I am using sql server 2008 r2 and I have two database, which is one have 11.000 record and another is just 3000 record, when i do run this query
SELECT Right(rtrim(tbltransac.No_Faktur),6) as NoUrut,
tbltransac.No_Faktur,
tbltransac.No_FakturP,
tbltransac.Kd_Plg,
Tblcust.Nm_Plg,
GRANDTOTAL AS Total_Faktur,
tbltransac.Nm_Pajak,
tbltransac.Tgl_Faktur,
tbltransac.Tgl_FakturP,
tbltransac.Total_Distribusi
FROM Tblcust
INNER JOIN ViewGrandtotal AS tbltransac ON Tblcust.Kd_Plg = tbltransac.Kd_Plg
WHERE tbltransac.Kd_Trn = 'J'
and year(tbltransac.tgl_faktur)=2015
And ISNULL(tbltransac.No_OPJ,'') <> 'SHOP'
Order by Right(rtrim(tbltransac.No_Faktur),6) Desc
It takes me 1 minute 30 sec in my server (I query it using sql management tool) that have 3000 record but it only took 3 sec to do a query in my another server which is have 11000 record, whats wring with my database?
I've already tried to backup and restore my 3000 record database and restore it in my 11000 record server, it's faster.. took 30 sec to do a query, but it's still annoying if i compare to my 11000 record server. They are in the same spec
How this happend? what i should check? i check on event viewer, resource monitor or sql management log, i couldn't find any error or blocked connection. There is no wrong routing too..
Please help... It just happen a week ago, before this it was fine, and I haven't touch the server more than a month...
as already mentioned before, you have three issues in your query.
Just as an example, change the query to this one:
SELECT Right(rtrim(tbltransac.No_Faktur),6) as NoUrut,
tbltransac.No_Faktur,
tbltransac.No_FakturP,
tbltransac.Kd_Plg,
Tblcust.Nm_Plg,
GRANDTOTAL AS Total_Faktur,
tbltransac.Nm_Pajak,
tbltransac.Tgl_Faktur,
tbltransac.Tgl_FakturP,
tbltransac.Total_Distribusi
FROM Tblcust
INNER JOIN ViewGrandtotal AS tbltransac ON Tblcust.Kd_Plg = tbltransac.Kd_Plg
WHERE tbltransac.Kd_Trn = 'J'
and tbltransac.tgl_faktur BETWEEN '20150101' AND '20151231'
And tbltransac.No_OPJ <> 'SHOP'
Order by NoUrut Desc --Only if you need a sorted output in the datalayer
Another idea, if your viewGrandTotal is quite large, could be an pre-filtering of this table before you join it. Sometimes SQL Server doesn't get a good plan which needs some lovely touch to get him in the right direction.
Maybe this one:
SELECT Right(rtrim(vgt.No_Faktur),6) as NoUrut,
vgt.No_Faktur,
vgt.No_FakturP,
vgt.Kd_Plg,
tc.Nm_Plg,
vgt.Total_Faktur,
vgt.Nm_Pajak,
vgt.Tgl_Faktur,
vgt.Tgl_FakturP,
vgt.Total_Distribusi
FROM (SELECT Kd_Plg, Nm_Plg FROM Tblcust GROUP BY Kd_Plg, Nm_Plg) as tc -- Pre-Filter on just the needed columns and distinctive.
INNER JOIN (
-- Pre filter viewGrandTotal
SELECT DISTINCT vgt.No_Faktur, vgt.No_Faktur, vgt.No_FakturP, vgt.Kd_Plg, vgt.GRANDTOTAL AS Total_Faktur, vgt.Nm_Pajak,
vgt.Tgl_Faktur, vgt.Tgl_FakturP, vgt.Total_Distribusi
FROM ViewGrandtotal AS vgt
WHERE tbltransac.Kd_Trn = 'J'
and tbltransac.tgl_faktur BETWEEN '20150101' AND '20151231'
And tbltransac.No_OPJ <> 'SHOP'
) as vgt
ON tc.Kd_Plg = vgt.Kd_Plg
Order by NoUrut Desc --Only if you need a sorted output in the datalayer
The pre filtering could increase the generation of a better plan.
もう1つの問題は、マルチスレッドだけである可能性があります。クエリは、11.000行のためにコストのしきい値に達すると、並列プランを取得する可能性があります。もう1つのクエリは、行が低いため、通常の計画にヒットします。SSMSクエリ内に実際の実行プランを含めることで、生成されたプランを確認できます。
たぶん、あなたは手がかりを得るためにそれらの計画を比較することができます。これで問題が解決しない場合は、ここに投稿して、フィードバックを受け取ることができます。
これがお役に立てば幸いです。テーブルの構造、テーブルのサイズ、パフォーマンスカウンターなどを知らずに、良いヒントを与えるのは簡単ではありません。:-)
