Thread: Creating an index on PostgreSQL 7.4.3
Hello,
I have a client who is still using the version 7.4.3
and creating an index like this doesn't work:
CREATE INDEX client__ascname__idx ON client (TO_ASCII(lower(name),'LATIN 1'));
Does exists another way of creating an index in varchar who take on consideration also the accents
Thanks!

No, it doesn't work always the same message:
ERROR: parser: parse error at or near "(" at character 47

I think expression indexes need another level of parenthesis, so maybe:
CREATE INDEX client__ascname__idx ON client ((TO_ASCII(lower(name),'LATIN
1')));
Have a nice day,

In that case you're not really talking to a 7.4 server, but something
older --- either syntax works OK for me on 7.4.
regression=# create table client(name text);
CREATE TABLE
regression=# CREATE INDEX client__ascname__idx ON client (TO_ASCII(lower(name),'LATIN 1'));
CREATE INDEX
regression=# select version();
version
----------------------------------------------------------------
PostgreSQL 7.4.12 on hppa-hp-hpux10.20, compiled by GCC 2.95.3
(1 row)

Sorry, the exact version is
PostgreSQL 7.3.3 on sparc-sun-solaris2.8, compiled by GCC gcc (GCC) 3.3.2

Even if you don't need usable expression indexes, compelling reasons can be found at http://developer.postgresql.org/docs/postgres/release-7-3-14.html and following pages. regards, tom lane
