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.
