我有一个表值函数.我还有一个标量值函数,我已经声明了一个临时表.我想在标量值函数内部执行表值函数,并在临时表中设置该值,如下所示

 **Exec @tempTable=TableValuedFunction**

我怎么能这样做？

这是表值函数

ALTER FUNCTION [dbo].[fn_Functiont]()
RETURNS TABLE 
AS
RETURN 
(   
SELECT d.*, b.Name AS Name, ps.Name AS PaymentSystemName, c.UserName AS UserName, c.FirstName AS ClientFirstName, c.LastName AS LastName, c.Number AS DocumentNumber, c.Id
FROM Document AS d
JOIN System AS ps ON d.SystemId = ps.Id
JOIN Client AS c ON c.Id = d.ClientId
LEFT JOIN Shop AS b ON b.Id = d.ShopId
WHERE d.OperationTypeId IN (2, 4, 5) AND c.Type = 1
)

我试图访问我的XML文件中的一些节点,但我不能让它工作,因为我可能不理解Delphi中的XML-Namepsaces.

我正在努力在我的TComoBox中获取我的一个Item的ItemIndex ...通常这对我来说似乎不是一件难事......但不知怎的,当我尝试施放我的String(我从一个SQL select)到TObject.这似乎不起作用.我尝试通过手动将String写入Object来调试我的代码,如下所示:

TObject('U');

那不知何故确实有效,我无法解释......

我填写ComoBox的方式:

for i := Low(_VerkaufTypenBez) to High(_VerkaufTypenBez) do
begin
    CBBelegart.AddItem(VerkaufTypenBez(i), Tobject(VerkaufTypenShort[i]));
end;

我尝试设置索引的方式:

CB.ItemIndex := CB.Items.IndexOfObject(TObject(SetIndexWithSQL('select top 1 * from KOMSAconfig_Allgemein', 'Belegart'))); //index = -1
helper := 'U';
CB.ItemIndex := CB.Items.IndexOfObject(TObject(helper)); //index = -1
CB.ItemIndex := CB.Items.IndexOfObject(TObject('U')); //index = 1

有什么建议？
