Which one of these two queries would be fastest?
Assuming everything is properly indexed. (1) INSERT INTO my_table_1 (field1, field2) SELECT DISTINCT field1, field2 FROM my_table_2; or (2) INSERT IGNORE INTO my_table_1 (field1, field2) SELECT field1, field2 FROM my_table_2; Is there anything to say about this in a general sense, or does it all depend on the data in question?

MySQL and phpMyAdmin
I just installed phpMyAdmin, made the appropriate changes in the config.inc.php file, and got the following error when accessing it via both IE and Safari on Mac OS X Panther client. #1251 - Client does not support authentication protocol requested by server; consider upgrading MySQL client I am using MySQL 4.1.10, the latest stable release, with phpMyAdmin-2.6.1-pl3, which the documentation says are compatible.

Re: MySQL and phpMyAdmin
Did you try searching on the error message first? I got hundreds of hits in Google for this. Searching the mysql docs, the first hit http://dev.mysql.com/doc/mysql/en/old-client.html has the explanation. The short version is that password security has been improved in mysql 4.1, so clients need to be compiled against a 4.1 mysql client library to work. Your copy of php, however, is compiled against an older version of the client library (probably 3.23). You can tell mysql to accept old-style passwords (details in the documentation linked above)for one or all users, but the better solution is to fix your copy of php, either by installing a php package pre-compiled against the newer client library, or by building php from source yourself using your copy of the mysql client library. Either way, you can find directions at the php site and elsewhere.

Question on Unicode/UTF8
I know this issue has been brought up many times and I have tried to search and read as much as possible but still have not been able to resolve my issue. I have a mysql database (not the latest but it supports unicode). I am keeping some columns in utf8 format and only save data that is in utf8. However, when I read the data back (I am using mod_python and mysqldb module) I see characters like the following on my web page: %u0631 Now if I replace %u with #x in my python code b/f sending them to browser, everything displays fine! Am I doing something wrong in mysql side? I have just defined the encoding for the columns I want to utf8. Is there anything else I have do in MySQL to get the data from tables in the right format that is displaybed in the broswer (I set the character set to utf-8 by Apache in my http headers). I have tried many different things (including setting client or connection character set) but have not been able so far to get the data back the way I want from mysql. Or, is this the job of the python to do the conversion. I appreciate any help. -Jalil
myodbc, mysql 5.0.0-alpha
I'm having trouble compiling myodbc-3.51.11 against mysql 5.0.0 - something about int2str has too many arguments - should I be using a newer version of myodbc (I couldn't find one), or is it not supported yet for mysql 5.0.0, or ...?

Oracle to MySQl conversion
Good evening all, I've got an Oracle text dump from a client for conversion to MySQL. Before I dive into SED or Perl does anyone know of a script to convert the dump file? I did the dev site by hand, not much to it, the site is fairly simple. Mostly NUMBER to INT, VARCHAR2 to VARCHAR, and CLOB to BLOB. Just don't want to duplicate the effort.
