一連の出席記録に基づいて、正しいログインとログアウトを取得しようとしています。これがサンプルデータです。

TKSTYPE = 0 - 入力 1 - 出力

私のジレンマは、ユーザー クエリの日付に基づいて次のログインを取得することです。ユーザーの正しいログアウトを取得できるようにします。たとえば、ユーザー PH120013 のログインを確認したいのですが、日付は 2012-08-26 です。私の望ましい出力は次のようになります。

          IN                              OUT

PH120013 2012-08-26 02:30:00.000 2012-08-27 15:00:00.000

ここに私の完全なクエリがあります:

データベースについてよくわからないので、これは一般的なソリューションであり、ほとんどすべてのデータベースで機能します。

select * from (
select logi_in.logdatetime as 'IN' , logi_out.logdatetime as 'OUT' 
from MSTR_ATTENDANCE logi_in
left outer join MSTR_ATTENDANCE logi_out

and logi_in.tkstype=0
and logi_out.logdatetime =(
