This one is weird. And I don't know exactly what I have the ability to
provide you for information. Below is the C# code I use to execute a
query. And below that is what is ultimately translated and executed. The
c# application appears to get hung up and loops. It burns cpu, but never
stops. But the same (translated) code will run in seconds if I cut and
paste it into Sqlite Expert. I'll keep poking around and see what else I
might be doing.
All comments about my syntax are welcome.
Have a good one!
