DECLARE @States_For_Interval TABLE

(id integer, Equipment_id integer, Status_Id integer ,reason_id integer, location_id integer, starttime datetime, endtime datetime, Duration integer)



.....Do some stuff...



UPDATE @States_For_Interval

SET Duration = datediff(ss,@starttime,@endshift)

WHERE starttime = (SELECT MAX(endtime) FROM @States_For_Interval)





SELECT * FROM @States_For_Interval

ORDER BY starttime

You have to define the Table structure with the Returns keyword and use that to populate and select.

Attached is the SQL Server Template 
CREATE FUNCTION <Table_Function_Name> 

(

	-- Add the parameters for the function here

	<@param1, sysname, @p1> <data_type_for_param1, , int>, 

	<@param2, sysname, @p2> <data_type_for_param2, , char>

)

RETURNS 

<@Table_Variable_Name> TABLE 

(

	-- Add the column definitions for the TABLE variable here

	<Column_1, sysname, c1> <Data_Type_For_Column1, , int>, 

	<Column_2, sysname, c2> <Data_Type_For_Column2, , int>

)

AS

BEGIN

	-- Fill the table variable with the rows for your result set

	

	RETURN 

END

GO

Thanks,
I tried that before, but was getting another error, I must have resolved that one because it is working now.

Cheer,
