yesterday accidentally found an Access database automatic numbering initialization of a method, the Internet is said to use Excel to rearrange the import or compression and repair database, I think this is misleading everyone. Here I share a new method that I have proven in practice. When you open the Access database, open the table, menu-View-Design view, move the cursor to the field of ID (AutoNumber), and then right-click to select the Delete row, and a pop-up window prompts: "Do you want to permanently delete the selected field and all of its data?" Select "Yes". The ID field is generally set as the primary key, and the Delete field ID is also prompted for Microsoft Office Access to remove the primary key. If ... "Select Yes", you add a new field named ID, the data type is set to AutoNumber, and then switch to Datasheet view, prompting "Do you want to save the table now?" Select "Yes" and you will find the automatic numbering initialized!
