Chris commented on Chris's blog post Comparing MySQL Statement-Based and Row-Based Replication
"Correct... The ordinal position of the column matters very much.  But try to convert a column on the slave to a different column type, lets say, from varchar(255) to text, and you'll start running into issues."

E. Souhrada commented on Chris's blog post Comparing MySQL Statement-Based and Row-Based Replication
"It's not true that the schemas must be the same between master and slave if you're using row-based replication. The slave schema can have additional columns not present in the master provided that those columns are at the end of the table…"

MySQL Workbench - Top 13 things you should know

MySQL Workbench has come a long way and keeps getting better! I honestly don't think that millage may vary on this one as it is one of the best no-cost GUI tools created for MySQL.I've always been pro command line for MySQL administration; however, there have always been powerful GUI tools that can aid administration, development and other tasks. Some great tools that I have used in the past are Toad, Navicat, phpmyadmin, and WebYog. Although all of the tools listed above are good I have had a…See More

Simple Automation - Examining your MySQL Index Usage

I have a new article posted on the Database Journal...- Abstract -In the majority of MySQL systems, the schema is always updated and changed based on the needs and focus of the application, making it somewhat difficult to keep up with all of the changes that come down the pipe.Knowing how to index a schema based on the queries using the system is a great skill to have. In the majority of the systems I have worked on, the schema is always updated and changed based on the needs and focus of the…See More

I'll make it to the UC next year for sure, if for no other reason than to heckle :P

The Oracle move is for one of 5 product lines I take care of, so I'll definitely still have MySQL around. We've been moving a design that wasn't scalable to a new architecture, and working an Oracle switch into the equation (where it has it's own set of problems...good times indeed).

As too lunch, screw that, you and the wife and kid (still one kid right?) are having steak on ValueClick ;) .

I've been thinking about going up to San Fran for a longish weekend with the wife and kids...I'll let you know when.

I've been great really. Busy as hell with VCLK. We're transitioning a big chunk of data to Oracle. As for the UC, isn't it next April or something? I might be in the bay area for Oracle's Openworld in Oct, but I'm not sure. I'll probably make the UC next year...who knows.
