Then a simple string comparison also happens to be correct for dates. For more complex date and time manipulation, see http://sqlite.org/lang_datefunc.html Igor Tandetnik ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users

You can always store the data as you want, but to do any calculations, you can use the datetime functions to convert to an appropriate format to do the math.

[sqlite] SQL example using date()
I would like to do a date search to find records that are between two dates. The dates are stored in the table in the format DD-MM- but I can change that to another format but I prefer something readable rather than an int or double. Could someone point me to some docs that could help me write the SQL and figure out the best format I should store my dates in?
