是否有方法在不删除从属项的情况下更改(删除/创建)用户定义的表类型

是否有一种方法可以更改(删除并创建)用户定义的表类型而不删除依赖对象。

我有这种桌子类型

CREATE TYPE [dbo].[ttOrderItems] AS TABLE(
    [Position] [int] NULL,
    [ItemCode] [varchar](16) NULL,
    [QtyOrdered] [int] NULL,
    [UOM] [varchar](2) NULL,
    [PriceQuoted] [decimal](10, 2) NULL
)

和依赖表类型函数

CREATE function [dbo].[ftCatalogItems](@comno varchar(3),@cuno varchar(6),@items  ttOrderItems readonly) returns table as
/*-------------------------------------------------------
DECLARE @COMNO VARCHAR(3)='010',@CUNO VARCHAR(6)='000164'
declare @items ttOrderItems;
select * from @items
insert @items
select '1231-221',1,'EA',20.20
union  select '110223-245',10,'EA',2001.20
--------------------------------------------------------*/
return(
    select Position,ItemCode,QtyOrdered
        ,PriceQuoted
        ,Net
        ,t$qanp QtyApplicable
        ,Status=case 
                when t$item is null then 'Not in Catalog' 
                when t$stdt > getdate() then 'Availle only on or after '+Convert(varchar(30),t$stdt,106)
                when  datediff(DD,getdate(),isnull(nullif(t$tdat,''),'4712-01-01')) < 1 then 'EXPIRED'
                when items.PriceQuoted != Net then 'Quoted Price do not match Catalog price'
                else Null
            end 
    from @items items
    Left Join ediCatalog c on ltrim(c.t$item)=ItemCode AND COMNO=@COMNO AND T$CUNO=@CUNO  and c.[Server]=dbo.fsBaanServer()
)

现在我想更改(删除/创建)ttOrderItems类型,。如何在不首先删除ftCatalogItems的情况下执行此操作?
