SQLite Forum: Cancelling the query

Have the GUI set a flag that stops the loop from looping.

eg:

```
static int keepgoing;

void stopnow()
{
 keepgoing = 0;
}

void enterthread()
{
 keepgoing = 1;
 prepare(...)
 while (keepgoing)
 (
  step(...)
  reset(...)
  sleep(...)
 }
 finalize(...)
}
```

Dispatch enterthread on its own thread.  Then just have the GUI change keepgoing to 0 (call stopnow()).  Unless of course the statement is taking hours to run ... if it is only taking a few miliseconds then the overhead of even bothering to do anything else is hardly worth it.
