将 SQL 存储过程转换为 Linq

Question

我创建了以下存储过程：

PROCEDURE [dbo].[LeadScoring_CountClosedActions]
    (@UserId INT,
     @StartDate INT,
     @EndDate INT)
AS
BEGIN
    SET NOCOUNT ON

    SELECT TOP 1 
        COUNT(l.Extra) OVER () AS TotalRecords
    FROM 
        [dbo].[LeadScoringActions] AS a
    INNER JOIN 
        [dbo].[LeadScoringLeads] AS l ON a.LeadId = l.LeadId
    WHERE 
        a.AssignedToUserId = @UserId 
        AND a.DateCompleted > DATEADD(DAY, @StartDate, GETDATE())
        AND a.DateCompleted <= DATEADD(DAY, @EndDate, GETDATE())
        AND a.ActionResultType != 'System Closed'
        AND l.Extra IS NOT NULL
    GROUP BY 
        l.Extra
END

我尝试在 EF Core 中使用以下命令来执行它：

var count = await _context.Database.ExecuteSqlRawAsync($"exec LeadScoring_CountClosedActions @UserId={userId}, @StartDate={request.StartDate}, @EndDate={request.EndDate}");

但它总是返回 -1，所以我环顾四周，似乎我应该将存储过程转换为 Linq（请参阅这个问题的评论之一）

我想知道我会怎么做 - 我知道如何做一般的事情：

var count = await _context
                    .Actions
                    .Include(a => a.Lead)
                    .CountAsync(a => a.ActionResultType != LeadScoringConstants.SystemClosed &&
                                     a.DateCompleted > DateTime.Today.AddDays(request.StartDate) &&
                                     a.DateCompleted <= DateTime.Today.AddDays(request.EndDate) &&
                                     a.AssignedToUserId == userId &&
                                     a.Lead.Extra != null);

但我不确定如何执行

GROUP BY

- 在 linq 中，它将按

a.Lead.Extra

分组，或者是否可以执行

COUNT OVER

？

使用 linq 更好还是有办法执行存储过程并获得正确的结果？

最后我使用 linq 通过从数据库获取匹配操作来解决它，然后我从结果中获得了不同的额外属性并计算了它们：

var actions = await _context
                .Actions
                    .Include(a => a.Lead)
                .Where(a =>
                    a.ActionResultType != LeadScoringConstants.SystemClosed &&
                    a.DateCompleted > DateTime.Today.AddDays(request.StartDate) &&
                    a.DateCompleted <= DateTime.Today.AddDays(request.EndDate) &&
                    a.AssignedToUserId == userId &&
                    a.Lead.Extra != null)
                .ToListAsync();

var projectIds = actions.Select(a => a.Lead.Extra).Distinct().Count();
