私は最近転職したため、オラクルからSQLサーバーに切り替えました。オンデマンドでレポートを生成するストアド プロシージャを作成しようとしています。レポートには、毎月の金額とこれらの金額の合計が表示されます。私は主にこれの合計部分に問題があります。完全なクエリは、この投稿の一番下にあります。私の非常に長いクエリからわかるように、Total_Current_Plus_Archived 列の合計金額を取得するために、基本的に 2 回書きました。これにはローカル変数 (@totalReportSum) を使用することを考えていました。合計列が計算されるたびにこの変数を更新したかったのですが、使用する構文に関係なくエラーが発生しました。ここに私が試したことのいくつかがあります：

試行 1。

--March total   
                     (SELECT @totalReportSum  =@totalReportSum + Count(*) AS Expr1 
                      FROM   dbo.accident_information AS ai 
                             INNER JOIN dbo.municipality AS mx 
                                     ON mx.agency_ori = ai.agency_ori 
                      WHERE  ( mx.ram = m.ram ) 
                             AND ( ai.crash_date >= @year + '-03-01' ) 
                             AND ( ai.crash_date <= @year + '-03-31' )) 
                     AS March_Total_Reports,

試行 2。

--March total   
                 @totalReportSum = (SELECT Count(*) AS Expr1 
                      FROM   dbo.accident_information AS ai 
                             INNER JOIN dbo.municipality AS mx

                     AS March_Total_Reports,

可能であれば、うるう年をどのように説明できるかについての提案もお願いします。

ヘルプやヒントは大歓迎です。ありがとう。
