SQL Server加入不起作用

Question

我有3个表Worker，Worker_issue和Worker_receipt

Worker主键为id，Worker_issue和Worker_receipt有外键worker id。

当worker_issue的行数超过Worker_receipt时，我会从查询中获得准确的结果，但当worker_receipt的行数超过Worker_issue时，我的结果为空查询。

以下是我在SQL Server 2008 Express中的存储过程

ALTER PROCEDURE dbo.WorkTDS
   @id int
AS  
   WITH WorkerIssue AS (
     SELECT
         ROW_NUMBER() OVER (ORDER BY [Worker_issue_temp].id) RowNum, *
     FROM 
         [Worker_issue_temp] 
     WHERE 
         [Worker_issue_temp].workerid = @id),
    WorkerReceipt AS (
     SELECT
         ROW_NUMBER() OVER (ORDER BY [Worker_receipt_temp].id) RowNum, *
     FROM 
         [Worker_receipt_temp] 
     WHERE 
         [Worker_receipt_temp].workerid = @id),
    WorkerTable AS (
      SELECT * 
      FROM [Worker])
   SELECT
       w.id AS ID,
       w.labour AS Labour,
       w.waste AS Waste,
       IssueDate,
       IssueParticular,
       CASE WHEN IssueWeight IS NULL THEN 0 ELSE IssueWeight END AS IssueWeight,
       CASE WHEN I_Rate IS NULL THEN 0 ELSE I_Rate END AS I_Rate,
       ReceiptDate,
       ReceiptParticular,
       CASE WHEN R_Rate IS NULL THEN 0 ELSE R_Rate END AS R_Rate,
       CASE WHEN ReceiptWeight IS NULL THEN 0 ELSE ReceiptWeight END AS ReceiptWeight
   FROM
       (SELECT 
            f.date AS IssueDate, f.id AS IssueID,
            f.particular AS IssueParticular, f.rate AS I_Rate,
            f.weight AS IssueWeight,
            f.workerid AS IssueWorkerID,
            u.weight AS ReceiptWeight, u.rate AS R_Rate, u.date AS ReceiptDate,
            u.id AS ReceiptID, u.isDeleted AS ReceiptIsDeleted,
            u.particular AS ReceiptParticular, u.weight, 
            u.workerid AS ReceiptWorkerID
        FROM
            WorkerIssue f 
        FULL OUTER JOIN
            WorkerReceipt u ON u.RowNum = f.RowNum) AS abc,
      WorkerTable AS w 
   WHERE
       abc.ReceiptWorkerID = w.id

   RETURN
