arithemtic in buffers

[Birju Prajapati]

Hi,
I have a buffer with the follwing:

insert into merge.rule (property, type, source, source_index) values
('primary', NULL,  15,  0);
insert into merge.rule (property, type, source, source_index) values
('primary', NULL, 1, 1);
insert into merge.rule (property, type, source, source_index) values
('primary', NULL, 12, 2);
insert into merge.rule (property, type, source, source_index) values
('primary', NULL, 10, 3);
insert into merge.rule (property, type, source, source_index) values
('primary', NULL, 11, 4);
insert into merge.rule (property, type, source, source_index) values
('primary', NULL, 9, 5);

....and so on....

I need to increase the value of the last digit on each line by one. Is
there an automagic way to do this via emacs? Do I use regular
expressions, M-x calculator, both, or something else to do it? Any
help would be much appreciated

TIA
Birju

How did I find those pages? Searched for "increment". HTH

Personally, I have a preference for using \, in a regexp replacement,
like

C-M-% [0-9]$ RET \,(1+ \#&) RET

Of course, this is glossing over the fact that there is no good way to
increase a 9.

And it requires a developer version of Emacs.
