How to insert Data from a function on server A into a table on Server B.

Question

Hi,
I have a function which is like this
DECLARE @oldmax bigint, @newmax bigint
SELECT @oldmax = max(exportTimestamp) FROM EXPORT_TIMESTAMPS
IF @oldmax IS NULL
SET @oldmax = 0
SELECT * FROM ServerA.TableA.fnExportTrafficTS(@oldmax) ORDER BY storeID, TrafDate
SELECT @newmax = max(timestamp) FROM TRAFFIC t
IF @newmax > @oldmax
INSERT INTO EXPORT_TIMESTAMPS
VALUES(@newmax, GETDATE())
And now i need to insert the data coming out of this function into ServerB Table B
And the column names and everything coming out of the function is the same columns in Table B.So, no need to worry there.
I have never worked with inserting data from function through linked server.
Can someone please help me with this?
Thanks,
Sujith

Well, first of all, your table structure doesn't match the structure of returned table by your table-valued function.
This is what table valued function returns:
[storeID] varchar(32) default('noRefID'),
[TrafDate] [datetime] default(NULL),
[QtyTraffic] [float] default(0)
And this is what your table structure is:
[tUTL_JobLogging_Key] [int] NOT NULL,
[StoreId] [varchar](10) NULL,
[TrafDate] [datetime] NULL,
[Visits] [numeric](8, 2) NULL
Apart from different size for the StoreID and using float vs. numeric and different name for the last column, there is one extra column in your table.
So, this is the first problem you need to correct.
Also, please post how exactly you're calling your procedure? E.g. the procedure has 2 parameters, but the values of them are not used as you're calculating them in the code. So, I assume they should not be parameters for the procedure.
