Hi Wm, appreciate the compliments. I've had the scripts in on form or
another for a few years. Went from mySQL>MS SQL Server>postgres.
Finally putting them in version control gave me a reason to church them
up a bit.
I certainly don't expect any level of general acceptance. However I
have little interest in converting anything to sqlite. I don't know who
ayPeter Keen is, but if he has any gnucash sql work I'm always
interested in checking something like that out. Also, It's probably
possible to still use all of this using postgres foreign data wrappers
to somehow read from sqlite.
I just wanted to share in case someone could take away bits and pieces
and use for themselves. If there any any suggestions I'm happy to
review and incorporate them.
I did add the two java classes for compiling/aggregating the JRXML
files into a single PDF.
I'll have to add some documentation for them.
A customizer class for one of the Jasper reports:
Anyway maybe getting a bit off topic. I'm happy to discuss further off
