Get all Persons via Database select

Question

Hello all,
if you ever need to get all Persons and its string values in an easy way directly from your database such as the xpath select
" Select * from /Person" use following Database select against your FimService Database:
--determine dynamically the columns for pivot
DECLARE @cols AS NVARCHAR(MAX),
@query  AS NVARCHAR(MAX)
select @cols = STUFF((SELECT ',' + QUOTENAME(Name)
                    FROM [fim].[ObjectValueString] AS [o]
                    INNER JOIN [fim].[AttributeInternal] AS [ai]
                    ON [ai].[Key] = [o].[AttributeKey]
                    WHERE            
                    [o].[ObjectTypeKey] = 24   
                    group by Name FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'),1,1,'')
set @query = N'SELECT ' + @cols + N' from
             (SELECT        
                [ai].[Name],
                CAST ([o].[ValueString] AS NVARCHAR(MAX)) as Value,
                ROW_NUMBER() over(partition by [ai].Name order by [o].[ValueString]) rn
                FROM [fim].[ObjectValueString] AS [o]
                INNER JOIN [fim].[AttributeInternal] AS [ai]
                ON [ai].[Key] = [o].[AttributeKey]
                WHERE       
                [o].[ObjectTypeKey] = 24 --Type for Persons
             ) x
             pivot
                Max(Value)
                for Name in (' + @cols + N')
             ) p '
exec sp_executesql @query;

Answer 1

You could create new stored procedures which do not use the additional search criteria.
For example: sp_get_all_room_names()
or: sp_get_all_room_numbers()
Alternately, when searching by ints, your stored procedure could accept a max and a min value. Your Java class which calls this stored proc could intelligently search for one value (both min/max the same) or all values (pick decent min/max values).
For example: sp_get_room_numbers(min, max)
I hope this gives you a few ideas to run with.
