![]() Our goal is to simply decide which field is important enough to become our. While you can use Access’s automatically generated primary keys to help you rebuild record links in Airtable, they will not be useful for maintaining links.Īfter converting a base from Access to Airtable and recreating links, I usually discard primary keys that were generated by Access, unless they are used outside of the database itself.Īirtable also does not enforce the requirement for a unique primary key, unlike Access. The primary field is always the first column and it cant be moved or deleted. All linked records in Airtable must be explicitly linked (either manually or through code). Access connects records based on a primary/foreign key system. I do want to caution you that Airtable handles linked records very differently from Access. Once autonumber is large enough, you can delete the blank records and use the following formula. There is at least one Airtable trick you can do ALMOST to make this work but tit's more clever than useful.JonathanBowen described one excellent method for having an auto-incrementing number in Airtable.Īnother option that uses three fields instead of four is to create a bunch of blank records until the Autonumber increments to past the largest of the old member numbers. ![]() I believe that MiniExtensions has a feature that will autoincrement values based on a value in a previous record but I haven't used this and am not sure that it would solve your problem. And of course FileMaker gives you more field-level validation options than you will ever need. Tadabase does a much better job in this area. Display images, text, and other data from your Airtable base Update Airtable records from a form Create new Airtable records with a form Prefill the fields. This lack of field level validation routines is a major weakness of Airtable. What I normally end up doing at least for certain validation tests (say, non-emptiness) is define a formula field that applies the tests and displays a result like "ERROR: ZIP CODE MISSING" if something is wrong. Check Netlify vs Gatsby Cloud comparison page for in depth. The primary field is required so that it can be used as a brief description of a record in other parts of the UI. Content here will discuss using those features to augment or modify the default content layout. The primary field is meant to be a short, unique representation of each record in your table. Dumb, but that's how it is.Īirtable has almost no field-level validation features: you can't validate a record for uniqueness, for length, or much of anything else. The primary field is always the first field in any record, and cannot be deleted, moved, or hidden. If you want to start with 1000, to guarantee that all values have four characters, you have to create 999 records first, then delete them. You also can't easily set the starting value. Architects many-to-many relational data tables using Linked Records Strong command of managing Airtable Views and Airtable Forms Monitors and assists data validation procedures. You can't import into it (as you sometimes need to). But there are still other problems with this type of field. If you do, Airtable will not reuse those numbers: If you create an autonumber field, get it to enter 1, 2, and 3, then delete 3, the next record you create will not be numbered 3, it will be 4 (because 3 was used earlier). Now you can change the Name field to an Autonumber field. What if a second appraisal or field review is required can we update the Loan. For example, sometimes two people actually have exactly the same name and that's still not a problem for Airtable for the reason explained above: this isn't the actual key value. But the default setup of the Name field does not require that the values in that field be unique and there isn't any way to prevent duplicates there. The value in this field - if you do things right - will help you identify this record as representing something unique - a product, say, or a person, or a tree. Here "primary" means it's the first column shown in grid view, and you cannot move it around the way you can move all the other columns. Records in a relational database can be sorted and physically stored in any order, but the key field (or fields) define uniqueness for that record. This is not a primary KEY, it's just a primary FIELD. What you're talking about is the NAME field. You can create a formula field that unhides the recordID - but you can't edit it. That's one of the main characteristics of the various no-code database products like Airtable or Tadabase: the handling of keys is taken care of behind the scenes. Let me start by pointing out that neither you nor your users have access to the actual primary key field. The basic answer is, no, Airtable does not support what you want to do.
