= is not working on a char(30) coloumn for me.
I want to find rows with equal name.
I have my database set to unicode.
SQL1
SELECT h1.key,h1.name,h2.key,h2.name
FROM table1 as h1, table1 as h2
WHERE h1.name=h2.name
and h1.OID = 730716
produces result rows where name doe not match
name is multibyte UTF-8 values.
SQL1
SELECT h1.key,h1.name,h2.key,h2.name
FROM table1 as h1, table1 as h2
WHERE h1.key=h2.key
and h1.OID = 730716
produces correct results.
key is single byte UTF-8 values only (digits only)
I have a hash index on name, I dropped it and got a different but still wrong
result.
key is part of a multicolumn primary kay
version 8.0.3 - gcc 3.4.3 fedora 3
Any suggestion on how to match multibyte characters? Do I need to use a
differnt comparison operator?
Thanks,
Grant

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match
