Multi parameter values selection problem in Report

Hi,

I am using parameter selection in my Report which i am connecting to Oracle through Linked SQL Server.

The following works well when selecting parameter value:

SELECT * FROM OPENQUERY(DATAINT,'SELECT * FROM GSM_NODES') WHERE TECHNOLOGY=@TECHNOLOGY

I have problem when i am selecting multiple values, the following query used which I used "IN" instead of "=".

Found out error while running this query.

SELECT * FROM OPENQUERY(DATAINT,'SELECT * FROM GSM_NODES') WHERE TECHNOLOGY IN @TECHNOLOGY

Please let me know what's wrong with my query.

Thanks.
