JSONQuery, part 1

You’ve been developing JSONQuery over the last few years, and today… Continue reading JSONQuery, part 1View the full article

Virtual List Reporting, part 4

Introduction Back in 2017 I wrote about a technique to enable users to a) produce multiple on-screen reports, and b) interact with those reports in browse mode. The article was called Virtual List Reporting, part 3, and while the approach it advocated works well enough under most circumstances, today I’d like to share some fresh… Continue reading Virtual List Reporting, part 4View the full article

Set Variable By Name Re-Revisited

Demo files: set-var-by-name-v4 and set-var-by-name-md5 Background This is a quick follow up to last December’s Set Variable By Name Revisited, and to avoid repetition will assume the reader is familiar with the material that was presented in that article. But to briefly recap: 1. FileMaker does not provide an obvious way to programatically name a… Continue reading Set Variable By Name Re-RevisitedView the full article

PSOS – Run Script in File not open Locally

INTRODUCTION Today I want to take a look at a certain Perform Script On Server (PSOS) behavior, and for those who find this behavior to be inconvenient, propose a work around. Here’s the behavior, or misconception, actually: a server side script initiated via PSOS (apparently) cannot access files on the server unless the user already… Continue reading PSOS – Run Script in File not open LocallyView the full article

The JSONata site is packed with useful information, including this short video… …as well as… Extensive documentation A link to the Stack Overflow forum, where you… Continue reading FileMaker 19 + JSONataView the full article

Bypassing Scientific Notation

Earlier today I needed 1 billion to render in the calc engine as 1000000000, but FM helpfully converts numbers to scientific notation if they A) are >= 1 billion, and B) contain nothing but zeros following the initial digits. Example where “A” and “B” are both true: Example where “A” is true but “B” is… Continue reading Bypassing Scientific Notation View the full article

FRAP-Map: A Flexible, Robust, Accessible and Portable Data Mapping Technique

Editor’s note: today we have a guest article by long-time FileMaker developer, Peter Doern, who has come up with an elegant, outside-the-box methodology for managing imports. This is one of the coolest techniques I’ve seen in a long time. Enjoy. FileMaker includes a powerful and fast method for importing data from a source table to… Continue reading FRAP-Map: A Flexible, Robust, Accessible and Portable Data Mapping Technique View the full article

When 2 is greater than 10

Today we’re going to take a quick look at a potential “gotcha” that can crop up when doing numeric comparisons. Jason DeLooze and I discussed the general behavior back in 2011 (Space Is The Place), but this time around I want to focus on one particular set of circumstances where the problem can arise. At… Continue reading When 2 is greater than 10 View the full article

Fun with SQL Joins and Currency Formatting

Demo file: sql-join-fun-etc.zip requires FM 18 or later. Recently I was asked to create a mini-report combining data from a pair of related tables via ExecuteSQL. This provided an opportunity to think about SQL joins, and also to come up with a way to apply currency formatting to dollar amounts in the SQL query result,… Continue reading Fun with SQL Joins and Currency Formatting View the full article

File IDs, Table IDs and Field-Level Schema

Demo file:  file ids, table ids and field-level schema.zip (requires FM 18 or later) INTRODUCTION Recently I was asked to help document a FileMaker solution by creating and populating a “schema” table as per the above screen shot. One of the requirements was to programmatically determine internal ID numbers for the file and for the… Continue reading File IDs, Table IDs and Field-Level Schema View the full article

Set Variable By Name Revisited

Demo file: set-variable-by-name-v2.zip (requires FM 16 or later) INTRODUCTION You’ve probably heard the old joke that goes… Patient: Doc, it hurts when I do this. Doctor: Don’t do that. Perhaps you’re also familiar with the FileMaker equivalent? Developer: It hurts when I try to assign certain variable names. FileMaker: Don’t do that. Or how about… Continue reading Set Variable By Name Revisited View the full article

A Value List Experiment

Demo file: a-value-list-experiment.zip Note 1: today’s demo is recycled from the one that accompanied Virtual Portal, part 2. All we care about today is how we assign the parent company; the remainder can be ignored. Note 2: if you’re unclear on value list basics, check out Thinking About Value Lists, part 1. “I want it… Continue reading A Value List Experiment View the full article

A Simpler Backup Script

Demo file: backup-simplified.zip Like many developers I go back and forth between developing locally and in a hosted environment, and many years ago, I posted a couple articles featuring a simple backup script to create on-the-fly backups when working on local files. Recently a colleague pointed out that this backup routine, which I last wrote… Continue reading A Simpler Backup Script View the full article

Render Found Set as JSON Object

Demo file: found-set-to-json-object.zip (40MB; requires FM 18 or later) [Author’s note: the demo file is a work in progress.

The demo consists of a table of US customers… Continue reading Render Found Set as JSON Object View the full article
