OK, I've checked the archives and read msgs for two days, now I have to ask ...
I've installed mySQL from Redhat 7.0 distribution and got it running to my eyes ok:
Ver 8.8 Distrib 3.23.22-beta, for redhat-linux-gnu on i386
Server version 3.23.22-beta-log
Linux 2.2.16-22 #1 Tue Aug 22 16:16:55 EDT 2000 i586 unknown
mysqlbug doesn't run right, and I'm not smart enough to fix it.
Anyway, I'm into the tutorial on page 288 of the manual. I've entered the number in
the "shop" table, listed them out, and all looks ok. But, my SELECT to return on a
match in the "price" column fails. I've tried various syntax, variations on the
SELECT (e.g. price > 10), etc. but always returns 0 rows. Below is a capture of a few
commands. No error messages, just wrong results. I've seen the Redhat 7.0 package
criticized here ... is this a case where I should blow away the default install and
load the latest? This is a server just for my self paced training which still seems
to be at ground zero. Any help?
session follows:
mysql> CREATE TABLE shop (
-> article INT(4) UNSIGNED ZEROFILL DEFAULT '0000' NOT NULL,
-> dealer CHAR(20) DEFAULT '' NOT NULL,
-> price DOUBLE(16,2) DEFAULT '0.00' NOT NULL,
-> PRIMARY KEY(article, dealer));
Query OK, 0 rows affected (0.00 sec)
mysql> INSERT INTO shop VALUES
-> (1,'A',3.45),(1,'B',3.99),(2,'A',10.99),(3,'B',1.45),(3,'C',1.69),
-> (3,'D',1.25),(4,'D',19.95);
Query OK, 7 rows affected (0.01 sec)

Empty set (0.00 sec)

If this is old ground covered elsewhere or if I should have posted my problem
elsewhere, please advise me: but I've really spent a lot of time trying to find it!!
