Dates Format in Promts using Session Variables

Question

Hi Experts,
I have an issue in controlling date format in prompts using session variable which I am using to set default value.
By default date format is timestamp E.g '2010-12-19 12:00:00 AM'.
As per requriement(s) I customized the date format in Reports as 19-Dec-2010 and I saved it as "System Wide Default for <Date Column Name> "
So, I got desired format in Reports and Date Prompts.
Now, I need to set a default value in Date Prompt. So, in RPD I created a Session Variable which returned me date in
DD-MON-YYYY format. Using follwing SQL :
SELECT REPLACE(CONVERT(VARCHAR(11), Getdate (), 106), ' ', '-') AS [DD-Mon-YYYY]
But in reports takes this value as string and not Datetime. So i got an error message.
A datetime value was expected (received "19-Dec-2010").
If i do not use above SQL to CONVERT date then default date in prompt get displayed as timestamp format and give me desired results but Formatting looks very odd in prompt
Is this a way so I can persist the [DD-Mon-YYYY] Formatting for default value which comes using variable and still run the report.
Above problem also exist vice versa that is if i SET that session variable and pass the datetime value to server. But there i guess I can use ToDate or some Casting in RPD column expression to handle that. Tell me if i am right ?
Thanks

That almost works. I had to adjust the syntax to the following...and then there are other issues doing this.
select cust_no, name,'@{session.currentUser}' from customersMy write-back SQL is this:
UPDATE customers SET NAME='@{c1}',LAST_EDITED_BY='@{c2}' WHERE CUST_NO=@{c0}But I don't want to display the cust_no column to the user. So I hide it in the UI. But if I do that I get the below error during write-back. Apparently sometimes when you hide a column on a direct query (numeric maybe?) the value doesn't transfer over to the write-back. If that's the case, this won't work for me. Hmm...
