Using Command blocks in Cognos datasource

[Niranjan81]

Hi,
I am using Cognos JDBC datasource . Due to the complexity of the queries , I need to pass few database hints as part of the cognos query to the datasource.
Can anyone advise , how to pass STRAIGHT_JOIN from Cognos to the database using the command blocks.
I tried to set by opening a command block, but it did not help.
The query from Cognos should form something like this.
select STRAIGHT_JOIN c1, c2, c3 from t1,t2...

Thanks,
NC
