I'm not sure what you mean. Each LazReport has a DataSet property, which can be assigned just before the report starts like this:

Code: Pascal  [Select][+][-]

1. frReport1.Dataset := frDBDataSet1;

frDBDataSet1 has a DataSet/DataSource property, you can also change that according to your needs:

Code: Pascal  [Select][+][-]

1. frDBDataSet1.DataSet := SQLQuery1;

The query can be linked to whatever database you like.

On the other hand it's also possible to create a report dynamically from scratch, you can find an example for FortesReport here: http://forum.lazarus.freepascal.org/index.php/topic,43151.msg301584.html#msg301584. You can do the same thing for LazReport, but building a complex report dynamically though it's not particularly hard, it's a time consuming task.
