Re: [android-developers] Re: Sqllite order by

Vinicius,

I had the same problem.

To solve it, I normalized the words, replacing the special characters for their correspondent ones ("áaaa" -> "aaaa") and stored them in a new column on the database. Then, I changed the query sort criteria to use this normalized column instead of the original one.

I remember that I tried to use SQLite collation with no success.

The problem is that in Unicode there is no relationship between a and á other than the order they appear in the character-set   To change this "natural" order you will have to define special relationships (sort order) for many of the Unicode characters.

Special characters in this case are accented. 

For example:

Our that base has the strings [áaaa,aaaa,bbbb], our function to order the query is returning in the following order:

aaaa,bbbb,áaaa

We need that the return of the query should be:

aaaa,áaaa,bbbb

I will check collating sequence that Richard suggested, but waiting for more ideas

we did a query in SQLlite, but the result is not in the order that we need, ie, the character "á" is being shown after z.

How can I configure my query to ignore special characters 

Which characters are "special" to you? It's kind of hard to spell certain words without certain accented characters, for 

example, "voilà".

'getNumericValue()' is a bad idea. It doesn't correspond to collation order. 'Ⅼ' will return 50. 'Ⅻ' will return 12.

There are methods to deal with collation order in Java in case the SQLite functions are just too "lite".

It's a big topic.
