IntroIn this lesson, you will learn how to build a developer-level function in Microsoft Access that lets you copy one or more records from any table without specifying field names, streamlining the duplication process even when dealing with indexed fields or AutoNumbers. We will talk about the shortcomings of Access macros for copying records, how to manually copy records, and different approaches using VBA code and append queries. Then, you will learn how to write a field-agnostic CopyRecords function, work with primary keys and AutoNumber detection, list table indexes, determine if fields are unique, and improve error handling. This is Access Developer 48.TranscriptIn today's class, we are going to build a function that will allow you to copy one or more records from any table without having to specify field names. I have been contacted many times about how trying to duplicate a record is a pain.First of all, there is a macro option for it and it is broken. It does not work. We will talk about that in lesson one. Unless you want to manually copy and paste records yourself, it is a pain if you have any fields that are indexed with no duplicates, whether it is your AutoNumber field or just any other field like an email address. If it is indexed with no duplicates, copying it, whether it is with VB code or SQL, is a pain unless you specify the entire list of fields from the table, which no one wants to do. If you make changes in the future, if you add fields, change fields, or delete fields, you have to go update all your code. So we are going to write a function where you do not have to do that. I like to call it table and field agnostic. It does not care. This class follows Access Developer 47. I strongly recommend you take all my classes in order, not because I am trying to sell more lessons, but because they really are designed to follow one after the other. My course is best taken in order - all the beginner lessons, expert, advanced, developer, Developer 1. Obviously, "Intro to VBA" and some other ones are important. Developer 15 covers error handling, which we are going to do a lot of today. Developer 16 covers record sets, definitely take this one, and in 24 we cover the Fields collection, which we are going to be using today. In 26, we cover TableDefs. These are all things that I am going to be using a lot of today. Plus, we have got a bunch of new stuff coming up today, including the Indexes collection, which is pretty cool. Like I always say, do not skip levels because you are going to miss stuff. This class is recorded with Microsoft Access as part of a 365 subscription, which I strongly recommend. It is currently January 2025. If you are using the retail version, this is roughly equivalent to Access 2024. However, the lessons covered today should work with any version going back to probably 2007 or so. I am not sure exactly when they broke that macro that I talked about earlier, but this is the version you need. If you have any questions regarding the material covered in today's class, scroll down to the bottom of the page that you are on and post your questions there. Also, take a minute to read through any other questions that have been posted as your question may have already been answered. Make sure you hit that red subscribe button so you will get notified if any other questions are posted or answers to your questions. Be sure to check out my Access forums. I have an awesome group of moderators. They rock. I get a lot of questions about anything Access related posted there. Now, let's take a closer look at what is covered in today's class. In lesson one, we are going to cover the background behind why we want to build the advanced copy records function. We will see how to manually copy a record. That is a beginner task, but we are going to go over it real quick. Then we are going to learn about the broken duplicate record macro. There is a macro item that just does not work. It used to work years ago. It does not work anymore. Then we will take that macro and convert it over to VBA code. I will show you how to fix it with, of course, one line of code. Then we will talk about issues with append queries and how you can use them to copy records. But again, you have to know all of the fields that you want to copy individually, which is a pain. We will review Developer 24's code, where I did show you how to loop through the fields, but again, you still have to know the field names. We will talk about all of that in lesson one and that will explain why we are building this function. In lesson two, we are going to start writing the copy record subroutine. We are going to loop through all of the fields. Then we are going to avoid the specified primary key, but we are going to specify it first. In the next lesson, we will learn how to not specify it. In lesson three, we are going to get rid of having to specify what the primary key field name is. We are just going to replace it with a basic WHERE condition. We are going to learn about the field attributes and the auto increment field attribute, which basically means this field is an AutoNumber. Now we can detect the AutoNumber and the primary key, instead of having to tell what it is. In lesson four, we are going to start off by writing a function to list all of the table indexes in a table's TableDef. So we can see what the index fields are. Then we will determine what the fields in each index are. Knowing this information, we can then write a function to determine if a specific field is unique. For example, is the email address unique? In other words, is it indexed with no duplicates? That is what we are going to do in this lesson. In lesson five, we are going to take that IsFieldUnique function and put it inside our CopyRecords function, which we are going to make a function now, so that we can check all the fields before we copy them and make sure they are not indexed with no duplicates. We are going to add some error handling. Then we are going to turn CopyRecords into a function and return the value of the newly created record, so we can do stuff with it like open up the form to that new record. Cool stuff.

SummaryToday's video from Access Learning Zone focuses on developing a function that lets you copy one or more records from any table in Microsoft Access without needing to specify each field name. Many students have reached out to me with questions about duplicating records, because it's often a hassle—especially if some of your table's fields are indexed with the "no duplicates" property. While there technically is a macro designed for this purpose, it simply does not work properly anymore. We will look at why that is in lesson one.If you've ever tried copying records where fields are indexed to prevent duplicates—such as the AutoNumber field or something like an email address—it can be a challenge with both VB code and SQL unless you specify every field individually. This becomes even more cumbersome in the long run, since anytime you update your table by adding or removing fields, you have to go back and revise all of your existing code. To resolve this, we are going to create a function that ignores field names entirely. This makes our code "table and field agnostic," letting it adapt to any table structure. This class builds directly on the material covered in Access Developer 47. As always, I strongly suggest you follow my class sequence in order. It is not simply a matter of purchasing more lessons; it's truly about ensuring that you have the foundational knowledge you need, as each course builds on the previous ones. You should have a solid background with my beginner, expert, advanced, and developer courses, as well as key modules like "Intro to VBA." Notably, Developer 15 addresses error handling (which will be important today), Developer 16 covers record sets (make sure you're solid on this one), and Developer 24 discusses the Fields collection, all of which are skills needed for this lesson. We will also use TableDefs as covered in Developer 26. What is new today is the use of the Indexes collection, something we have not fully explored before. My standard advice applies: do not skip class levels because each one fills in critical knowledge. For reference, I am using Microsoft Access as part of the Microsoft 365 subscription while recording this class, and I recommend using this version. It is January 2025, so if you're using the retail or stand-alone version, you can think of this as about Access 2024. However, what we learn here should be relevant for most versions going back to Access 2007. It is difficult to know precisely when Microsoft broke the Duplicate Record macro option, but that's no longer a reliable route. If you have any questions on the topics discussed in this session, please scroll down to the bottom of the page where you are watching and leave your questions there. It's also wise to browse existing questions, since someone else may have already asked what you're wondering about. Make sure to subscribe to get notifications for any updates or answers. Be sure to visit my Access forums as well. I have a fantastic group of moderators who are very helpful with all kinds of Access-related questions. Let me give you an overview of what we will be covering in this class. In lesson one, we will examine the main reasons for creating an advanced record-copying function. We'll begin by discussing how to manually copy a record, which is good review for beginners. After that, I will demonstrate the broken duplicate record macro—it used to work but is no longer reliable. I'll show how to take this macro and convert it to VBA, and then with a single line of code, make it work properly. We will then look at append queries and how they can be used for copying records. The main problem here is, again, the need to list every field by name. I will also discuss the solution from Developer 24, where we learned to loop through fields, but still faced the challenge of knowing field names. All of this background in lesson one will show why a new function is needed. In lesson two, we begin writing our copy record subroutine. Initially, we will loop through all fields except the primary key, which we will specify in this lesson. In the next lesson, I'll show how to make even the primary key detection automatic. Lesson three removes the need to manually specify the primary key field name. Instead, we'll use a WHERE condition and learn about field attributes and the auto-increment property—this helps us find the AutoNumber and primary key using code. Lesson four introduces a function that lists all indexes in a table's TableDef, so we can see which fields are indexed and whether any are unique. We'll write code to check if a specific field (like an email address) is unique, meaning it is indexed without duplicates. In lesson five, we integrate this IsFieldUnique function into our CopyRecords function to ensure we are not attempting to copy fields that are required to be unique. We will enhance error handling, and turn CopyRecords into a function that returns the value of the new record, so you can make use of it immediately—for example, to load the new record in a form. A complete video tutorial with step-by-step instructions for everything discussed here can be found on my website at the link below. Live long and prosper, my friends.
