Thanks Miyako. That’s useful. I basically was wanting to know if inline SQL used the “twinned” pre-emptive thread or not. Peter > On 19 Jan 2018, at 04:10, Keisuke Miyako via 4D_Tech <4d_tech@lists.4d.com> > wrote: > > are you familiar with the request log file? > > you will see a P (for

Docs about "twinned" process and pre-emptive mode

Hi I’ve been raking through the online documentation trying to find where the querying modes pre-emptive / co-operative are documented but have been unsuccessful. What I’m specifically looking for is more background on what conditions SQL queries use the twinned pre-emptive process for

Saving an object array to disk

Hi Has anyone used the SAVE VARIABLES command with an object array ? I am getting crashing when I try to read it back in with LOAD VARIABLES. The test data is tiny so it isn’t size that’s the problem. Just wondering if anyone’s tried it. (I’m trying to migrate an entire table for processing

Tip: Exporting to a target folder in a package

Hi I have XLIFF applications that generate stuff like custom constants and language resources. Unfortunately, if you use 4D’s desktop navigation commands like “Create Document(“”)” or Select Folder and the like, to allow the user (me !) to locate the target folder for the export, it doesn’t

Re: Use of Objects vs Global Variables (Was 'Arrays vs Objects...)

Well, I’m afraid I’ll have to take the pariah role here and politely disagree with you all :-)) - or at least present an alternative perspective in which “globals” play a very powerful and unique part. Lets think this all through for a moment. As is relevant to this topic, we can notionally

Arrays vs Object for Key/Value pair lookups

Hi I remember at last year’s summit, JPR was emphasising how objects were far more optimised than arrays for doing lookups over large numbers of key value pairs. e.g. we usually do this: $x:=find in array(myKEYS;”product_code_x”) if($x>0) $0:=myPRICES{$x} end if How do people prefer to do
