I give an example:

These are the datas from the table names:

id n1 n2
1 AaAa AaAa
2 X X
3 A A
4 a a
5 ab ab
6 _Y _Y
8 ..a ..a
9 .x .x
7 ...a ...a

If I run: select * from names order by n1: the result is:

id n1 n2
4 a a
8 ..a ..a
7 ...a ...a
3 A A
1 AaAa AaAa
5 ab ab
9 .x .x
2 X X
6 _Y _Y

Which I don't think that is right. I don't know what happened. But I find that the ASCII char order is not respected here.

I have another machine on which the result is okay....I don't have a clue.

Andy.

PostgreSQL 7.3.x and anything below has never had case insensitive sorting - period.
I can't speak for the new 7.4 version?

If you want to add a case insensitive data type try this:

Hi to everyone,

I don't know exactly if i'm sending my problem in the right place, hope you can help me.

I use postgresql db. 7.3.2.

Today I noticed that my database does not sort "case sensitive" anymore. If I have a query like:
Select name from names order by name -- the names are not resulted as they should. 'ax' is after 'Aa' and so one.

I don't know since when is this problem I noticed it just now. I use Suse 8.2 and yesterday evening I made a live update. Could this be the problem? I restored the system and ... the problem remains.

I also have another linux system, there the db works fine.

Does anyone has any ideea???? Are there any settings for something like this?

Thnkx.
Andy.
