Harish, Consider doing things outside sqlite. Definitely you should be using C API or php API or some other for making query to DB. Why don't you think of doing things outside sqlite VENKAT Bug the Bugs

Trim(X,Y) is useful but I need to remove anything other than '0' - ' '9' and a few more characters. 180+ characters need to be removed (filtered out). So I will need to call Trim() so many times. Since we cannot write loops I wonder how I can call it many times. -Harish Simon Slavin-3 wrote: > > > On 7 Feb 2011, at 8:38am, Harish CS wrote: > >> Table T has two varchar columns A and B.
