I need to migrate about a dozen tables from ORACLE 10g to MySQL 5. I
have manually migrated the schema to MySQL. I am able to write SQL*PLUS
queries to extract ORACLE data into insert statements (including date
conversions to MySQL format etc) that I can run against the MySQL
database. The CLOB
Hello,
I've two LEFT OUTER JOINS in the WHERE section in an Oracle script like:
select ...

where

and PT1.ID (+) = bl.PARENTTYPE_1
and PT2.ID (+) = bl.PARENTTYPE_2
...
MySQL knows LEFT OUTER JOINS in the FROM section but two joins with the same
table aren't accepted.

Ah right :-)
Storage engines are unique to MySQL? yes. Is that good? YMMV. Most
of the purported benefits can be achieved with Oracle's features
without the compromises of balkanised storage engines. You're right,
they're not offered by Oracle, or anyone else ... there's a reason no

Hi All:
I am doing a study on the migration of databases from Oracle to MySQL. In
this process, I gathered few points.
Overall, I think arguments can be made in favor of MySQL in terms of
performance, stability, ease of use, and cost. All of these things point to
decreased TCO when using MySQL

MySQL doesn't have (compared to Oracle):

Shawn, others
from a purely religous logical architecture viewpoint it is better to
keep the business rules as close to the persistence layer (ex. RDBMS)
as possible. in the practical physical/business world it is severly
hyperlinearly expensive (both hardware as well as Oracle licenses) to
support that model.
I will be migrating Oracle database 9i to Mysql. Do anyone have any
experience in doing this?. Please share with us!
Thank you very much,
