Question

ALTER FUNCTION [dbo].[TabloGetir] (@id  INT,
                                   @ay  INT,
                                   @yil INT)
RETURNS TABLE
AS
    RETURN
      (SELECT ARACKM_ARAC_ID,
              ARACKM_ID,
              ARACKM_TARIHI,
              ARACKM_KM,
              A_PLAKA,
              A_ID
       FROM   VARACKM
       WHERE  A_ID = @id
              AND MONTH(ARACKM_TARIHI) = @ay
              AND YEAR(ARACKM_TARIHI) = @yil)

这是我的表值函数，我一直有这个错误，有人可以帮助我吗？

这就是我所说的：

comm2 = New SqlCommand(@"select ARACKM_TARIHI, SUM(ARACKM_KM) AS TUTAR 
                         from VARACKM 
                         GROUP BY ARACKM_TARIHI 
                         HAVING [dbo].[TabloGetir](@A_ID,@ay,@yil) ",conn2)

comm2.Parameters.Add("@A_ID", plakaId)  
comm2.Parameters.Add("@ay", ay)
comm2.Parameters.Add("@yil", yil)
reader2 = comm2.ExecuteReader()

Answer 1

问题是having条款。

HAVING [dbo].[TabloGetir](@A_ID,@ay,@yil)

首先，您的函数返回一个表，having子句需要一个带有某种比较的标量。其次，你没有比较。也许你的意思是：

HAVING EXISTS (select 1 from [dbo].[TabloGetir](@A_ID,@ay,@yil) )

在期望条件的上下文中指定的非布尔类型的表达式，在'）'附近。错误
