SQL where子句未得到過濾

Question

我有以下查詢，但它沒有考慮p.created_by =@searchBy where子句中的如何更正它，以便根據@searchBy過濾結果。

ALTER PROC [dbo].[Rptcashcollectionouter] @branchId INT, 
              @searchBy INT, 
              @strDate DATETIME=NULL, 
              @endDate DATETIME=NULL 
AS 
    BEGIN 
     SELECT DISTINCT p.created_on AS paid_date 
     FROM reading re 
      JOIN billing_gen bg ON re.id = bg.reading_id 
      JOIN customer_registration cr ON bg.account_number = cr.account_number 
      JOIN payment p ON bg.bill_number = p.bill_number 
      JOIN customer_category cc ON cr.customer_category_id = cc.id 
     WHERE p.created_by = @searchBy 
      AND ((@strDate IS NULL) 
        OR Cast(Floor(Cast(p.created_on AS FLOAT)) AS DATETIME) >= 
         Cast(Floor(Cast(@strDate AS FLOAT)) AS DATETIME)) 
      AND ((@endDate IS NULL) 
        OR Cast(Floor(Cast(p.created_on AS FLOAT)) AS DATETIME) <= 
         Cast(Floor(Cast(@endDate AS FLOAT)) AS DATETIME)) 
      AND cr.branch_id = @branchId 
     ORDER BY p.created_on ASC; 
    END; 

Answer 1

檢查您的過程中的值如下。

SELECT @branchId, @searchBy, @strDate,@endDate 

然後嘗試使用相同的值手動運行SQL。另外，請確保您的表格中的數據符合您的標準。

此外，你究竟在嘗試什麼？

Cast(Floor(Cast(p.created_on AS FLOAT)) AS DATETIME) 

Answer 2

1. 在執行過程中，請確保您傳遞正確的值。

2. 打印所有即將到來的值（僅用於測試）。

3. @searchBy INT是整數類型。但我認爲「p.created_by = @ searchBy」是一種日期時間或日期類型，所以它也可能在這裏發生衝突，或顯示錯誤的結果。在下面一行。 p.created_by被視爲日期時間或日期，以@searchby爲整數。

   WHERE p.created_by = @searchBy
