proc sql preserve_comments option inside a macro

hi.

im using the sql procedure to retrieve data from an oracle server, and im trying to use Hints .

The problem is that the proc sql is inside a macro. When i run the SQL procedure not as part of the macro statement it works just fine ,

but when it is inside the macro it looks like the Oracle query optimizer is ignoring the Hints.

Is there a problem to use preserve_comments inside a macro ? or am i doing anything wrong?

thanks

gil
