In the beginning was the MySQL command line and it was good. Verbose yes, error prone yes, and even tedious. But it was good. The UPDATE USER set SELECT_PRIV=’Y’, DROP_PRIV_’Y”, UPDATE_PRIV=’Y’,……,LAST_BLOODY_PRIV=’Y”; type errors have caught of us old timers. But it was still good.

Then came some GUI tools that were okay. Not great but they had their uses.

And then came MySQL Workbench. And it was very good.

Now there is MySQL Workbench 6.2 and it is excellent. It came out in Beta last week and has built on the proven success of its predecessors. All the usual stuff is there – Server Status, Users & Privileges, Startup/Shutdown, logs, Dashboard, Performance Reports and more. But there area whole bunch of subtle little tweaks that make it easier to use.

For instance, the VISUAL EXPLAIN allows toggling between the visual display and the tabular display. Plus you can now get query …

In a previous post, my colleague Dimitri Vanoverbeke discussed at a high level the concepts of database as a service (DBaaS), OpenStack and OpenStack’s implementation of a DBaaS, Trove. Today I’d like to delve a bit further into Trove and discuss where it fits in, and who benefits.

Just to recap, Trove is OpenStack’s implementation of a database as a service for its cloud infrastructure as a service (IaaS). And as the mission statement declares, the Trove project seeks to provide a scalable and reliable cloud database service providing functionality for both relational and non-relational database engines. With the current release of Icehouse, the technology has begun to show maturity providing both stability and a rich feature set. …

Loops -> Repetitive tasks

3 types of loops in MySQL stored program:
- Simple loop using LOOP and END LOOP clauses
- WHILE and END WHILE clauses that runs while a condition is true
- REPEAT  and UNTIL clauses that runs until a condition is true



Termination of loop -> LEAVE statement.

I will demonstrate the use of loops the simple loop way.

Simple counter from 1 to 10:

Store below stored procedure in a file named my_loop.sql

DELIMITER $$
