So I have been using Base for a few months and am mostly OK with things, however Macros. Again mostly Ok but I’m a bit lost \ confused around this “createUnoService(“com.sun.star.sdb.Rowset”)” is there any actual documentation covering these services and how to use them, or indeed a list of them. At the moment I have been hunting through Macro examples etc to come up with solutions, probably would be better if I knew what I was doing 
Hello,
here you can download the SDK (software development Kit)
https://www.libreoffice.org/download/download-libreoffice/
If you install it, and then look into the IDL Reference, you’ll find “com.sun.star.sdb.Rowset” informations here:
sdk/docs/idl/ref/servicecom_1_1sun_1_1star_1_1sdb_1_1RowSet.html
