Sqlite order by string case insensitive8/26/2023 ![]() There is a blessed build of SQLite which integrates the ICU library for 'proper' unicode support on ordering/like/upper/lower but you would need to integrate that into the sqlite code used as the backing for the. Param1,param2, CultureInfo.CurrentCulture, CompareOptions.IgnoreCase) Public override int Compare(string param1, string param2) Of course if the performance of the user defined collation is more than enough for your present needs then go with that. Unless you have access to someone else's well tested and stable unicode culture sensitive sort in C++ I suggest sticking to the simple sort after approach where possible. Here is one persons attempts to do it in c++. net functions but the overhead of calling back and forth across the managed/unmanaged boundary is considerable. SQLite 3 does allow user defined collation functions, and these can be done in SQLite.Net as. Since both are happening in the same process this shouldn't make a big difference in performance terms unless your dataset is very large.
