Question

我是否可以通过调用存储过程获取临时表的值？由于@productTable是一个临时表，我可以EXEC [dbo.FindProductTotal] 并获取[dbo.updateProductTotal]中的值？在我看来它不起作用。如果没有，有没有办法获得价值从第一个临时表的结果在第二个存储过程中执行？真正的编码更复杂，所以我不知道只是做简单的插入和更新表。我需要知道这种编码方式是否适用于我的实际编码。

ALTER PROCEDURE dbo.FindProductTotal (@ProductID int)
AS

DECLARE @productTable TABLE (subProductID int, productCode varchar(10), productDesc varchar(25), chargeAmt money)

    insert into @productTable 
    select productID, productCode, productDesc, chargeAmt
    from   product
    where region='CA'

--calculate charge here

    UPDATE @productTable 
    SET chargeAmt = (calculation here)
    where ProductID = @ProductID


ALTER PROCEDURE dbo.updateProductTotal (@ProductID int)
AS

DECLARE @productTable TABLE (subProductID int, productCode varchar(10), productDesc varchar(25), chargeAmt money)

EXEC dbo.FindProductTotal @ProductID = 123456

    UPDATE dbo.Manufacture
    SET    productChgAmt = p.chargeAmt 
    FROM   @productTable p
    WHERE  productID = @ProductID

    CREATE PROCEDURE dbo.FindProductTotal (@ProductID int)
AS
    IF SELECT OBJECT_ID('tempdb..##productTable') IS NULL
    DROP TABLE ##productTable

    CREATE TABLE ##productTable(subProductID int, productCode varchar(10), productDesc varchar(25), chargeAmt money)

    --DECLARE @productTable TABLE (subProductID int, productCode varchar(10), productDesc varchar(25), chargeAmt money)

    insert into ##productTable
    select productID, productCode, productDesc, chargeAmt
    from   product
    where region='CA'

--calculate charge here

    UPDATE ##productTable
    SET chargeAmt = (calculation here)
    where ProductID = @ProductID


CREATE PROCEDURE dbo.updateProductTotal (@ProductID int)
AS

EXEC dbo.FindProductTotal @ProductID = 123456

    UPDATE dbo.Manufacture
    SET    productChgAmt = p.chargeAmt 
    FROM   ##productTable p
    WHERE  productID = @ProductID
