Dear Experts,

I have some knowledge of T-SQL.
I have created a select query which suits my needs.

However, I would like to convert this select query to function / stored procedure (?)
and pass @dzien as variable so that I can call it from e.g.
Visual Basic in Excel or even join with other tables.

Something like

1.

{CALL dbo.returnmyview (2015-01-01)}

or better
 
2. select * from dbo.returnmyview (2015-01-01) join XXXXX

I am sorry for my crazy syntax but I hope you get the point.

The select query has been uploaded here:

thank you in advance!
best regards
Jarek

My work spam filter prevented me from viewing the outside link, so here's a mockup
CREATE PROC returnmyview (@dzien date) AS

/*
Looky here, meaningful code comments!

02-09-15  ja-rek  Completely original work
*/

SELECT bingo, bango, bongo
FROM SomeTable
WHERE dzien = @dzien
GO

Hi Jim,

thanks a lot - that works!
that's the simpler version, can you please convert it to version 2? (as I have it described in my question)

so that I can use join, union etc on the output, something like

select * from dbo.returnmyview (2015-01-01) join XXXXX

I recommend against a tvf, as the Query Compiler can't incorporate table-valued functions into a query plan, so execution will be off.

Explain why you need it.

You need to use an in-line table-valued function, not a multi-line TVF.

Please post the actual code so that such a function can be written.

But just post the query directly.  NO chance I'm downloading anything from a site with that many flashing colors!!

Hello and thanks for help!

declare @dzien DATETIME --@dzien is my parameter that I want to pass
set @dzien = {ts '2015-01-31 00:00:00'}

select 
PRE_Kod,
PRE_Imie1,
PRE_Nazwisko,
dkm_nazwa,
PRE_DataUr,
PRE_Plec,
left(pre_kategoriaopis, 2) CAT,
CAST (pre_etaetatl as decimal) / CAST (pre_etaetatm as decimal) MANYEARS,
case when pra_parentid is null then 1 else 0 end HEADCOUNT,
case when PRE_ZatrudnionyDo< {ts '2999-12-31 00:00:00'} then 1 else 0 end TEMPORARIES,
PRE_MLDWojewodztwo,
PRE_ETAStawka, 
PRE_ETAWymiar, 
PRE_DataOd, 
PRE_DataDo, 
PRE_ZatrudnionyOd, 
PRE_ZatrudnionyDo
from cdn.pracetaty
JOIN CDN.Pracidx ON PRI_PraId = PRE_PraId
join cdn.prackod on pra_praid = pre_praid
left join cdn.DaneKadMod on DKM_DkmId = PRE_ETADkmIdStanowisko 
where pri_typ = 1
and PRE_DataOd<@dzien and (PRE_DataDo is null or PRE_DataDo>=@dzien)
and PRE_ZatrudnionyOd<@dzien and (PRE_ZatrudnionyDo>=@dzien or PRE_ZatrudnionyDo is null)

Open in new window



why I need it?
a pro would find a more efficient workaround, but for me the possibility to use select instead of exec is more convenient.
the table/database is rather small and I don't think I will suffer from a loss in speed (it this troubles you).
