VFP 9 SQL and Industry Standards (by John Koziol)

John Koziol is calling on the FoxPro community to bang on the new SQL features in the Visual FoxPro 9 beta.

I posted a few of those changes yesterday and there are more to come.

If you've got a lot of tables, try it out.

John - one thing that was commented by Frank Camp was that with the removal of all these limitations, the amount of code that can be on a single line is going to be an issue. The max length is still 8192 characters and if you have to specify the individual fields, it's going to be an issue. I don't usually post ERs on the blog but the one thing I would hate to see in code is:

lc = "SELECT " + lcFlds + " from " +lcFrom + "....."
&lc

He also singled out Aleksey Tsingauz and David Anderson for their efforts on this.

It's great to learn more about who's making up the "handful of earnest" guys - instead of just the usual suspects we always hear about. Keep it up John!

Thanks for mentioning Frank's comment.

In our (Frank's and my) case, we create the views in xCase, so we aren't pasting parts of the SQL together; but we then modify it in various ways, programatically, before generating it. And in the end, it becomes &lcSQL, of course.

We were among those pushing for increasing the 9-join limit (since the VFP7 beta); but without a mechanism to programatically generate what we are capable of creating, it will be mostly for naught.

Attending Southwest Fox 2019 could change your life - Find out how

Southwest Fox is coming up in October and as I do every year, I spoke with the organizers Rick , Doug and Tamar on the FoxShow. Deadlines for Southwest Fox: Super-saver price (before July 1): $695 Early-bird price (before August 1): $770 Regular price (August 1 and later): $820 This year, I took a different approach with separate shows for each organizer but the main message is still the same : July 1st is their Go/No-Go date. Conferences don't talk about this very often. I don't think developers really question if Apple will hold their WWDC in June or Microsoft will hold their Build conference - but that's because those conferences are vendor-led. Southwest Fox is a community-driven conference - it's not driven by a company with an agenda. Listen to the interviews and you can hear how important each of the organizers feel the live connection between speakers and among attendees.

Well, that explains CodePlex...

In a move that will be sure to anger open source (or rather anti-paid software, anti-Microsoft open source)  zealots, Microsoft is planning to buy GitHub . A year ago, I mused about why Microsoft would shut down CodePlex and how the world needs competing source code repositories to be strong. I'm not the only one per this Slashdot article  : "...   people have warned about GitHub becoming as large as it did as problematic because it concentrates too much of the power to make or break the open source world in a single entity, moreso because there were valid questions about GitHubs financial viability...." - Jacques Mattheij I will be interested in seeing this play out - whether developers jump ship or not. Have all the efforts Microsoft has made in pushing towards open source be seen as genuine or will all the zealots jump ship or maybe even attack? Microsoft's comment about why they shut down CodePlex referred to how spammers were using CodePlex. Well, GitHub

FoxInCloud Stats

FoxInCloud sent this link a while back about their statistics regarding visits to their site: http://foxincloud.com/blog/2017/12/27/VFP-community-lessons-from-foxincloud-site.html What's interesting here is the breakdown of people. Yes, I think it's understandable that the Fox community is getting older. Another factor is the growth of the mobile and web environments taking over development. These environments really do push people towards the newer non-SQL or free SQL/hosted environments but more towards hosted storage options like Amazon and Google. A tool like FoxInCloud that helps MOVE existing applications to the cloud inherently competes with those environments. But FoxInCloud also allows developers to extend their application further by giving them a starting point using Javascript and the basic CSS (such as Bootstrap). If you're not rebuilding your application from scratch, it's certainly a great step forward. FoxPro VFP
