If this is your first outing, I would go with something simpler. If the data support it, you could simply keep things in the original Excel arrangement. > Any help would be very much appreciated. If you have Excel files implies you're running on a Windows machine? It might be too much to try at once, but you could consider installing ActivePython, http://activestate.com/Products/activepython/ which would then let you use ActiveX data objects to pull directly from the .xls file, and then populate the sqlite file. This would be faster than writing everything out to the hard drive. However, if the data migration is a one-time event, ignore what I have just said, as it is not worth the complexity. > Scott > Cheers, Christopher L.

The C/C++ documentation can be found here: http://sqlite.org/capi3ref.html#sqlite3_create_function For those of us in the mortal category, various wrappers can make life better.

RE: [sqlite] Functions embedded in SQL statements
Bud, I could well be educated on the point, but I think that this is exactly how you go about adding functions for use in the SQL. R, Christopher L. Smith Have you pondered the meaning of life today?

I am using Tcl. I am looking for the functions that appear to extend the SQL syntax. I did not see either of the two functions I mentioned (ifnull, strftime) on those pages. bb --- Christopher Smith <[EMAIL PROTECTED]> wrote: > The C/C++ documentation can be found here: > http://sqlite.org/capi3ref.html#sqlite3_create_function > > For those of us in the mortal category, various wrappers can > make life > better.

[sqlite] RE: ezmlm response
SQLite illuminati, Some questions: 1. If the integer primary key (say, tbl_pers.pers_id) is the b-tree value for the row, is it necessary to compose update triggers to handle a DELETE FROM tbl_pers WHERE pers_id=5; for all of the tables holding pers_id as a foreign key? 2. I want to update the values of a field based on another table. Can I express this in SQL, or do I need to write an explicit code loop? UPDATE tlkp_a INNER JOIN tbl_b ON tlkp_a.event_type_id = tbl_b.event_type_id SET tlkp_a.event_type_id = tbl_b.event_type_id; The gist of this is that I want to write an Access=>ANSI SQL tool that dumps the Access database to a text SQL DDL file, but the AutoNumber=>INTEGER PRIMARY KEY is a little problematic. Might have to stoop to two files with a script in between to manage the procedural aspects. :( Not the worst outcome, overall.
