How to set the SQL Query String in CE 9.0 - CWR url

[Raguna]

Hi,
Currently i am using CE 9.0 - CWR method to access the reports. Most of the reports are filtered by selection formula (SF) command in the URL.

Now i need to pass the SQL statement string in the URL instead of SF. I tried SF does not allowed SQL String.

For example :-

http://<server-name>/viewrpt.cwr?sf={expression}

Please input your valuable ideas or suggestion.
Thanks & Best Regards,
Ragu
