Question

declare @company_branch_id uniqueidentifier = 'd3534ff2-b2b2-473f-9be1-e03069bf5c87' 
declare @dateFrom date = '10/8/2013' 
declare @dateTo date = '11/9/2013' 


DECLARE @tbl TABLE(
    tbl_Ref varchar(50) 
    , Reference varchar(100) 
    , customer_branch_id uniqueidentifier 
    , trans_date datetime 
    , duedate datetime 
    , Charge decimal(18,4) 
    , Credits decimal(18,4) 
    , Allocated decimal(18,4) 
    , Outstanding decimal(18,4) 
    , pay_amount decimal(18,4)) 

Insert into @tbl 
Exec [dbo].[usp_getCustomerBalanceRpt] @company_branch_id, @dateFrom, @dateTo 

UPDATE @tbl 
SET trans_date = (SELECT tbl_Rental_InvoiceMaster.Date 
        FROM tbl_Rental_InvoiceMaster 
        INNER JOIN @tbl ON @tbl.Reference = tbl_Rental_InvoiceMaster.Reference 
        WHERE tbl_Rental_InvoiceMaster.Reference= @tbl.Reference 
        AND @tbl.tbl_Ref='Rental Invoice') 
SELECT * FROM @tbl 

@company_branch_id，@dateFrom，@dateTo是傳遞給sp的參數。 當執行被顯示在上面的代碼ERROR鄰近

INNER JOIN @tbl ON @tbl.Reference = tbl_Rental_InvoiceMaster.Reference 
WHERE tbl_Rental_InvoiceMaster.Reference= @tbl.Reference 
AND @tbl.tbl_Ref='Rental Invoice' 

爲'Must declare the scalar variable "@tbl".'

Answer 1

當我們在一個連接使用表變量，我們需要別名表，以執行該查詢。

以下查詢應該工作：

UPDATE @tbl 
SET trans_date = (SELECT tbl_Rental_InvoiceMaster.Date 
        FROM tbl_Rental_InvoiceMaster 
        INNER JOIN @tbl t ON t.Reference = tbl_Rental_InvoiceMaster.Reference 
        WHERE tbl_Rental_InvoiceMaster.Reference= t.Reference 
        AND t.tbl_Ref='Rental Invoice') 
SELECT * FROM @tbl
