You asked the right question. Past 3 yrs whether the gap has come down or not. I started working with MySQL 4.7… where there was no triggers and stored procedures. Now 5.0 onwards I am enjoing it. And Oh, since innoDB and MySQL became the wealth of Oracle who care to afgue for FOSS MySQL?

You shold not be lazy to simply copy & paste an oracle trigger / procedure to MySQL to run. There are wayout for everything in my experience if you donot have a hardfist…

We should accept one thing that Oracle to MySQL migration has become a trend. This will continue as a a hot topic indeed.

In the case of databases, I’ve seen poorly implemented Oracle solutions and wonderfully implemented MySql solutions. In general, it is management’s responsibility to align the problem (or objectives), with the tool, and the skill of their staff.

Right now my company is doing stuff on Oracle I couldn’t even think about on MySQL. Fairly large Enterprise workloads in ETL, OLTP, and some emerging OLAP databases. Fortunately, I’m driving good revenue and have a talented/dedicated DBA team to support it. Basically, as my problem has evolved, so have the tools and people I use to keep pace.

Or, is this the most updated summary?

I’m not a dba, but a developer. Oracle allows to put code and intelligence in the db, mysql does not. Oracle laughs at big ugly complex queries, while mysql shines at retrieving rows directly.

However, the cost of joins, the inability to use indexes inside views or functions, and the unexplainable (or very time-hungry-to-solve) losses of performance are quite hard to work with.

This changes my approach to programming. With mysql, performance is always a serious concern. With oracle, never.

What is DB? A storage! I don’t need any other junks!
What is DBM? ?? + Manager! I don’t need any other junks!
MySQL is enough for most practical situations!
