I think I'd probably set up aliases that invoke mysql or mysqladmin
with a --defaults-extra-file option that contains the username/password
for the appropriate account.
Groan. More stuff to learn, configure, maintain, and memorize. I'm
trying to replicate Unix's "root vs. mere user" security paradigm in
MySQL. I can do "drop table" as sbk without hurting myself. Doing it
as keeling risks data loss.
I think your analogy is flawed. If you really want the root vs mere
user distinction, the anolgy would be that you su to the appropriate
user before running MySQL programs. If you did that, the .my.cnf
for each user would be read correctly.
How about if I submit a feature request? Parse the command line. If
command == bar and MySQL user == foo, find foo's password stanza for
bar in ~/.my.cnf, and use that password. That shouldn't be difficult.
If you submit a feature request, I hope that it would be more detailed
than that. I suspect it's not so easy as you think.
Why does a perl program run by my login username ignore MySQL's
~/.my.cnf? Are MySQL users really embedding passwords in their code?
Because you're not using the mysql_read_default_group or
mysql_read_default_file option in your connect string, most likely.
This is what I do after parsing command line arguments:
# construct data source
my $dsn = "DBI:mysql:sampdb";
$dsn .= ";host=$host_name" if $host_name;
$dsn .= ";port=$port_num" if $port_num;
$dsn .= ";mysql_socket=$socket_name" if $socket_name;
$dsn .= ";mysql_read_default_group=client";
# connect to server
my $dbh = DBI->connect ($dsn, $user_name, $password,
{ RaiseError => 1, PrintError => 0, AutoCommit => 1 });
