The only SQL interface I'd really be happy to use (if I had to use SQL) is
something using placeholders, sort of like [expr], but perhaps written in the usual SQL style:
[sql select * from candies where flavour=? and colour=?]
I am actually considering going back to this idea, as I can't seem to figure out why my current version of [sqlite] is crashing. Hans said that PD generally doesn't crash, and for other externals that I have written, I was able to track down the bugs because it was crashing within my external. Here it is crashing while executing PD code, and that tells me that PD DOES crash.
I wish there were some sort of tutorial on troubleshooting problems like this, mostly because I don't really know where to start with something like 'gdb'.
you wouldn't modify the statement any more than you modify an [expr] at runtime. this allows the statement to be precompiled by the server. you could still allow runtime change but perhaps it would get messy with multiple inlets, so let's assume for now that it is not supported.
This is why I thought of this in the first place. You generally don't modify the SQL, except to insert data.
