PASSING parameter to store procedure using qlikview Interface

[#1]

HI

i'm using a stored procedure in qlikview which takes date as input parameter to generate a resultset.

wanted to know how can we pass parameter using qlikview to external program like stored procedure .

following is the procedure we use @ backend in sql

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER procedure [dbo].[BOMofAllItems]
as
begin
create table #aa(item varchar(5))
create table #ItemP(mitem varchar(5),sitem varchar(5),qty real,price real,basic real,tax real,curr varchar(10),cfactor varchar(5))

declare @item varchar(5)
declare @cdate datetime

set @cdate = getdate()

insert into #aa(item)
select distinct ltrim(t_mitm) from ttibom010111

select top 1 @item = item from #aa order by item
while(@item <> '' )
begin
insert into #ItemP(mitem ,sitem ,qty ,price ,basic ,tax ,curr ,cfactor)exec BOMofItem @item,@cdate
delete from #aa where item = @item
set @item = ''
select top 1 @item = item from #aa order by item
end
drop table #aa
select * from #ItemP
drop table #ItemP
end
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

and in qlikview

SQL

Declare

@cdate datetime

execute dbo.[BOMofAllItems]

@cdate = <parameter required>

store BOM into ..\QVD\Purchase_qvd\BOM.qvd;

in this case @cdate requires a date for which the procedure will be executed ....

when i'm passing value thru a variable declared in qv environment its not accepting that value ................

i'm wondering if there is any other method to pass input parameter to SP.

thanks in advance

Hi,

Its been a long time, but may be useful if someone search this again.

The date parameter need to be passed wrapped within the square bracket []. Set a variable which will give your date as [YYYY/MM/DD] and evaluate that date after SQL Exec and pass with stored procedure.

See below the sample script which I pull the modelled calendar from our SQL data warehouse based on fact table's max and min date:

FS:
SQL

EXEC [INFO].[dbo].[spQV_RTT_FreeSlots];

Temp_Calendar_Range:
LOAD

Min

(num

([FS.AppointmentDate]

))as

MinDate

,
Max

(num

([FS.AppointmentDate]

)) as

MaxDate

RESIDENT

[FS];

LET

vMindateFS

='['&date

(Peek

('MinDate',0,'Temp_Calendar_Range'),'YYYY/MM/DD')&']';
LET

vMaxdateFS

='['&date

(Peek

('MaxDate',0,'Temp_Calendar_Range'),'YYYY/MM/DD')&']';

//*/

Calendar:
NOCONCATENATE

LOAD

*,
[date]

as

[FS.AppointmentDate]

;
SQL

EXEC [INFO].[dbo].[spQV_Calendar_date_Between] $(vMindateFS)

, $(vMaxdateFS)

;

DROP

TABLE

Temp_Calendar_Range;
