How can I pass a Presentation Variable (Date) into a prompt

Question

Hello
How can I pass a Presentation Variable (date) into a prompt? I seem to be able to do this successfully for a non-date value but have had no luck with a Date variable.
Here's a simplistic version of what I'm trying to do:
1. I have a Presentation Variable called startDate which is a Date that defaults to this SQL - SELECT "Reporting Dates"."Measure Date" FROM Trading WHERE "Reporting Dates"."Date Name" = 'Current'.
2. I now want to pass this variable into a prompt with SQL like this: SELECT "Position Date"."Position Date" FROM Trading where "Position Date"."Position Date" = date'@{startDate}{2009-04-24}'
I get this error: Datetime value @{startDate}{2009-04-24} from @{startDate}{2009-04-24} does not match the specified format.
Now I can use the exact same syntax in a filter. For example, a simple Answers request where I pick Position Date with a filter saying "Position Date"."Position Date" = date'@{startDate}{2009-04-24}' works fine.
What am I doing wrong?
Thanks!

Answer 1

Can you provide more information please?
1. What is the format of the first date prompt, is it YYYY-MM-DD or?
2. Which data type is Position Date."Position Date" in the physical layer, date or date time?
3. What is the column formula in the first prompt?
4. The first prompt is set to drop-down or?
5. If you are using this SQL Results in the second prompt:
SELECT "Position Date"."Position Date" FROM Trading where "Position Date"."Position Date" = date '@{startDate}{2009-04-24}'
then @{startDate} must be in YYYY-MM-DD format to work properly, otherwise (for example):
datetime value 01/01/2000 from 01/01/2000 does not match the specified format.
This doesn't work for example:
SELECT Times.time_id FROM "Normal model" where Times.time_id =date '01/01/2000'
