2448 - MySQL - efficiency and other topics
Following on from the last two days of MySQL training, you'll see a number of blog entries covering stored procedures, securing a mysql server, and exploring database requests in PHP. Further technical diagrams can be found here ... including how to make your select queries efficient, table locking ....

2447 - MySQL stored procedures / their use on the web from PHP
Are there times when your PHP will pull a large result set back from MySQL, or have to make a large number of queries, just to further process the data into a relatively small dynamic section of a report? If so, why not have the MySQL do more of the work and return a much shorter, more processes r ....

2446 - Learn about MySQL stored procedures
Current releases of MySQL include "stored procedures". What are they? You may start by considering stored procedures to be "Macros" - a series of commands bunched together as one, or a complex command which is held within the MySQL daemon and called up by just a simple call. But they then go much ....

2445 - Securing MySQL on a production server
There's a conumdrum for the authors / distributors of any open source server software that's likely to be used in a productions environment - should they send it out so that it's quick and easy to try but needs securing, or so that it's well secured but therefore calls for a bit more effort when you ....

2444 - Potted MySQL installation
Putting MySQL onto a machine that may previously have had an install ... here's a summary of the commands we used yesterday. It's a useful checklist (reminders to get rid of old config files that could cause a new install to start with old data, for example) but you 'll need to adopt / adapt indivi ....

2443 - Contrasting Cambridge, Bristol and Wiltshire
When I'm in Cambridge, I try to stay as close as I can to where I'm working - and that's measured in driving minutes, rather that in miles. There are some places that are less than a mile apart as the crow files, but 20 minutes apart by road, with one way systems in place and uncrossed rivers and r ....

2442 - Variable storage - Perl, Tcl and Python compared
From Monday to Wednesday, I was teaching Python to a group of delegates at a company where I have previously taught Tcl and Expect and Perl. And this interesting diagram shows just what a contrast there is between the three languages right from the start - in terms of how data is stored into varia ....

2441 - Not your cup of tea?
When I travel, I'll usually grab a sandwich or fish and chips of an evening, and eat in my room; there's no great thrill in sitting alone in a hotel restaurant and there's often something on the TV (more than five channels is nice, but still surprisingly uncommon), or work to be done online. But on ....

2440 - Optional parameters to Python functions
Python functions (and methods) can be called with any number (0 or more) parameters, but the calling sequence must match the 'template' or 'function prototype' given when defining the function. Let's define a function: def fred(a,b,c=3,d=4,e=5,f=6):     print a,b,c,d,e,f That ....

2439 - Multiple returns from a function in Python
Convention states that you can call a function with many parameters, but you return just one. There's some truth in that statement, but of course you can often return a collection - an array, list, hash, dictionary or other composite object.
