Crosstab problem: Any workaround for that?

Question

Hi,
I've got a mater report, in which I use a subreport as detail. My subreport consist as a crosstable. For each record of the master report, I pass in parameter a key to the subreport to get the appropriated crosstable. The problem is that for one crosstable, I can get multiple page, and when printing/previewing the master report, if the record row returns a crosstable on multiple page, I only got one page print: the next ones are missing.
Is there a way to prevent that? Is there any workaround? maybee its my method that is not the best one to use in this case...
Thanks!

Define working perfectly.
Just because it's using an index doesn't mean it's efficient.
One proper solution here is to create a function-based index to reverse the string.
You could use the undocumented, unsupported REVERSE function to test but as a proper implementation you should probably implement your own reversing function.
That way, instead of a leading wildcard, you end up with a trailing wildcard and you can use an appropriate index when suitable.
e.g. something like
CREATE INDEX i1 ON t1 (REVERSE(col1));
SELECT *
FROM    t1
WHERE REVERSE(col1) LIKE REVERSE('%Value');
