EF Core 存储过程错误：'@p1' 附近的语法不正确 [关闭]

Question

在执行 API 调用时，我收到以下错误：

Microsoft.Data.SqlClient.SqlException (0x80131904): Incorrect syntax near '@p1'

所以，我有以下存储过程：

/****** Object:  StoredProcedure [dbo].[sprocGetDataForSummaryTable]    Script Date: 30-Nov-21 00:23:17 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE   PROCEDURE [dbo].[sprocGetDataForSummaryTable] @StartDate datetime2(7), @EndDate datetime2(7), @AccountName nvarchar(50) AS BEGIN
                                        SET
                                          NOCOUNT ON;

                                        SELECT
                                          a.Name,
                                          DATEPART(YEAR, t.TransactionDate) AS Year,
                                          DATEPART(MONTH, t.TransactionDate) AS Month,
                                          SUM(t.Value) AS TotalValue,
                                          c.Name AS CategoryName,
                                          s.Name AS SubcategoryName
                                        FROM
                                          [PersonalMoneyTrackerDb].[dbo].[Transactions] AS t
                                          INNER JOIN Categories AS c ON t.CategoryId = c.id
                                          INNER JOIN Subcategories AS s ON t.SubcategoryId = s.Id
                                          INNER JOIN Accounts as a ON t.AccountId = a.Id
                                        WHERE
                                          t.Type = 'Expense'
                                          AND t.TransactionDate < @EndDate
                                          AND t.TransactionDate > @StartDate
                                          AND a.Name LIKE '%' + @AccountName + '%'
                                        GROUP BY
                                          a.Name,
                                          DATEPART(YEAR, t.TransactionDate),
                                          DATEPART(MONTH, t.TransactionDate),
                                          c.Name,
                                          s.Name
                                        ORDER BY
                                          DATEPART(YEAR, t.TransactionDate),
                                          DATEPART(MONTH, t.TransactionDate),
                                          c.Name;

                                        END
GO

以及以下 .NET 6 EF 核心调用：

public async Task<List<SummaryTableEntity>> GetSummaries(string startDate, string endDate, string accountName)
    {
        return await _dbContext.SummaryTableEntities
            .FromSqlInterpolated($"sprocGetDataForSummaryTable {startDate} {endDate} {accountName}")
            .ToListAsync();
    }

通过使用 SQL Server Profiler，我注意到它被翻译成：

exec sp_executesql N'sprocGetDataForSummaryTable @p0 @p1 @p2
',N'@p0 nvarchar(4000),@p1 nvarchar(4000),@p2 nvarchar(4000)',@p0=N'01/01/2020',@p1=N'01/01/2022',@p2=N''

我完全不知道这是什么问题，请帮忙。

看起来你缺少逗号来分隔参数：

return await _dbContext.SummaryTableEntities
            .FromSqlInterpolated($"sprocGetDataForSummaryTable {startDate}, {endDate}, {accountName}")
            .ToListAsync();
