VB中的存储过程
我在看别人的代码，有一个存储过程，我在数据库中右键存储过程--修改后打开是这样的：

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go

ALTER PROCEDURE [dbo].[ReverseForm]
@CreatorID int,
@FID int OUTPUT,
@FormNumber int=0 OUTPUT
AS
DECLARE @FormTypeID tinyint
DECLARE @MaxID int
DECLARE @SystemDate DateTime
DECLARE @StoreID int


-- Find the current formtype and storeid
SELECT @StoreID=StoreID, @FormTypeID=FormTypeID FROM Form WHERE FID=@FID


-- Find the store's systemdate
SELECT @SystemDate=Convert(char(10),getdate(),120)

-- Get the next formnumber for the current store and current formtype
SELECT @MaxID = MAX(FormNumber) FROM Form WHERE FormTypeID=@FormTypeID AND StoreID=@StoreID

IF @MaxID is NULL
SET @FormNumber = 1
ELSE
SET @FormNumber = @MaxID + 1

INSERT INTO Form (StoreID, FormTypeID, FormNumber, RelatedFID, ContractNumber, ClientID,
WarehouseID, WarehouseID2, CreatorID, SalesID, NoTaxSum, TaxSum, SystemDate,
SystemTime)SELECT StoreID, FormTypeID, @FormNumber, RelatedFID, ContractNumber, ClientID,
WarehouseID, WarehouseID2, @CreatorID, SalesID, 0, 0, @SystemDate, GETDATE() FROM Form WHERE FID=@FID


SELECT @FID = @@IDENTITY


我看不懂了，文中红色字体不是插入一条语句的意思吗？怎么没Value(......)这些？ 他这个是什么意思？

哪个知道？教一下我这个初学者。


[解决办法]
这个是把SELECT StoreID, FormTypeID, @FormNumber, RelatedFID, ContractNumber, ClientID,
WarehouseID, WarehouseID2, @CreatorID, SalesID, 0, 0, @SystemDate, GETDATE() FROM Form WHERE FID=@FID
筛选出来的结果插入Form表中,不需要values. insert into table(Fields) select Fields from anthorTable
