Copy Records Without Specifying Indexed Fields

Welcome

Welcome to Microsoft Access Developer Level 48, brought to you by Access Learning Zone. I'm your instructor, Richard Rost.

In this class, we're tackling the challenge of copying records in Microsoft Access without specifying field names. We'll build a comprehensive function that simplifies this task, making the process table and field agnostic.

First, we'll explore manual copying, then address the broken duplicate record macro. We'll convert this into functional VBA code, eliminating the hassle of field naming. We'll identify primary key fields, field attributes, and index uniqueness, creating a versatile copy records function.

Topics Covered

In Lesson 1, In we'll discuss the reasons for building the Advanced Copy Records function. We'll quickly cover manually copying a record, then look at fixing a broken duplicate record macro by converting it to VBA with just one line of code. We'll also address issues with append queries and the need to know all field names individually. Additionally, we'll review Developer 24's code on looping through fields, which still requires knowing field names. This lesson will clarify the need for the function we're developing.

In Lesson 2, we will learn how to create a subroutine to copy records, excluding the primary key, using VBA. We'll learn to set up record sets, and loop through fields while seamlessly updating and refreshing the record list in your form.

In Lesson 3, we will learn how to streamline our database operations by replacing primary key specifications with a simple WHERE condition. I'll show you how to identify AutoNumber fields using field attributes and perform bitwise operations effectively. We'll also address common issues with compact repair in Access.

In Lesson 4, we will llearn how to list all table indexes, identify their unique properties, and write a function to determine if a specific field, like an email address, is unique (indexed with no duplicates). We'll explore programmatically checking composite keys and use helper functions to assist in simplifying these advanced database tasks.

In Lesson 5, we will learn how to integrate the is field unique function into your copy records subroutine, effectively transforming it into a function. We'll cover error handling, identify the primary key, and enable the new function to return the ID of newly created records.
