Use variable parameter in Execute SQL Task multiple times SSIS - sql

Question

hey guys so i created two variables: startdate and todate and I am attempting to pass them through my SQL query in SSIS and I have added them in my Parameter Mapping but how does SSIS which variable to use after if it sees a third question mark?
for example: so how would SSIS know to use startdate when it inserts into #multileg and not use the todate variable?
e
--Declare #StartDate date
--declare #ToDate date
--set #startdate = dateadd(dd,-10, cast(getdate() as date))
--set #ToDate = dateadd(dd,-9,cast(getdate() as date))
---SSR Table with passenger info, both APAY and PET
create table #SSRData
([ssrfl] int, [ssrcode] char(4), [ssrsequenceid] smallint, [ssrstatuscode]
char(2), [servicestartcitycode] varchar(5),
[ssrstartdate] date, [databasetimestamp] datetime, [pnrlocator] char(8),
[pnrcreatedate] date, [passengersequenceid] smallint,
[namefirst] varchar(250), [namelast] varchar(250), [frequenttravelernumber]
varchar(25)
)
insert into #ssrdata
select distinct ssrfl,
s.ssrcode,s.ssrsequenceid,s.ssrstatuscode,s.servicestartcitycode,
s.ssrstartdate, s.databasetimestamp, s.pnrlocator, s.pnrcreatedate
,s.passengersequenceid, namefirst, namelast,frequenttravelernumber
--into #SSRData
from
(select cast(ssrflightnumber as int)ssrfl,
ssrcode,ssrsequenceid,ssrstatuscode,servicestartcitycode,
ssrstartdate, pnrlocator, pnrcreatedate
,passengersequenceid,databasetimestamp from dwjetblue2.dw.resssr
where SSRCode in ('APAY', 'PETC') and PNRLocator <>'purged'
and ssrstartdate >= ?
and ssrstartdate < ?)s
inner join dw.dw.ResPassenger p
on p.pnrcreatedate=s.pnrcreatedate
and p.pnrlocator=s.pnrlocator
and p.passengersequenceid=s.passengersequenceid
inner join dwjetblue2.dw.ResPassengerFT ft
on ft.pnrcreatedate=s.pnrcreatedate
and ft.pnrlocator=s.pnrlocator
and ft.passengersequenceid=s.passengersequenceid

create table #multi

[pnrlocator] char(8), [pnrcreatedate] date

,[servicestartdate] date
)
insert into #multi
select distinct

Answer 1

Brad's answer is a great way to do it. Another way is to simply add the parameter to your Parameter Mapping a second time.
A third way is to build your SQL statement in a variable with expressions. Then in your Execute SQL Task, your SQLSourceType would be Variable, and then you select the variable that contains your query. This can be an easy way to do it so you avoid messing around with picking the right data types for your parameters.

Answer 2

You wouldnt at the top of your code declare variables for the dates passed and set the values from the paramaters/? makrs to those and just use the variables in your code below
DECLARE #StartDate as Date
DECLARE #ToDate as DATE
SET #StartDate = ?
SET #ToDate = ?
-- so do it like this:
Select * from your table where MyDateColumn Between #StartDate and #ToDate
Then use those in your code below where you need them.
This lets you use the variables more than once and is cleaner and easier to see that your using parameters and how/where.
*** Updated to use your code:
DECLARE #StartDate as Date
DECLARE #ToDate as DATE
SET #StartDate = ?
SET #ToDate = ?
