我最近切换了作业，因此也从oracle切换到sql server。我正在尝试编写一个存储过程，它将按需生成报告。该报告将显示每月金额和这些金额的总和。我在解决这个问题的主要部分时遇到了麻烦。完整查询位于本文的最底部。 正如您将从我的超长查询中看到的那样，我基本上已经写了两次以获得Total_Current_Plus_Archived列中的总和。我正在考虑为此使用局部变量（@totalReportSum）。我希望每次计算总列时更新此变量，但无论我使用何种语法，都会收到错误。以下是我尝试过的几件事：
尝试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,
尝试2。
--March total
@totalReportSum = (SELECT 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,
如果可能的话，我还想了解如何解释闰年的问题。
非常感谢任何帮助或提示。感谢。
