So would it be very difficult porting the existing stuff to 
KOffice2? In case the situation with kexi won't improve there 
would be some serial letter functionallity at last.

I don't know if I would be up to the task, but to be honest I'm 
not very interessted in kexi, which is certainly a very good 
piece of software, but personally I'm more concerned about data 
integration in environments with already existing database 
backends.

I was thinking of a more simple way:

Click "Edit current entry"->displays tables
Select a table->issues "select * from <table>"->displays records 
in "Query result"-widget
Select one or more records->constructs query->displays query in 
query input field
Click "Execute"->executes query

Still rather arward but you would have both: simple 
point-and-click record selection and constructing more complex 
queries by entering them directly in the text input. Additionally 
you would cut one step for inserting database variables in your 
document, since the selection of the table would already make the 
fields available. 

Admittedly I haven't looked into the source for quite a while now, 
but unless I'm not completly wrong, this should be possible by 
only modifying KWQtSqlPowerSerialDataSource.cpp

I guess it would be nicer to have a common data view plugin for 
koffice but that seems to require a bit more effort.
 
Anyway, thank you for your kind response. I guess as soon as I 
have a proper build environment I'll give it a shot.

Ciao
Joerg
