Yes, you do need normalization. You need to divulge "what you are trying to do" instead of asking "how to emulate a non-relational implementation". -----Ursprüngliche Nachricht----- Von: sqlite-users [mailto:sqlite-users-boun...@mailinglists.sqlite.org] Im Auftrag von Peng Yu Gesendet: Mittwoch, 10.

There is only one string in each row, not many strings separated by some separator. A string can include white space characters. In other words, a string can be a word or multiple words separated by white spaces. Would it be possible to create indexes at a subcolumn level? I think if indexes can be created at the word level (or prefix of words, as I frequently search for things like a noun and its plural form together), then the search can be faster. -- Regards, Peng _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users ___________________________________________ Gunter Hick | Software Engineer | Scientific Games International GmbH | Klitschgasse 2-4, A-1130 Vienna | FN 157284 a, HG Wien, DVR: 0430013 | (O) +43 1 80100 - 0 May be privileged.
