Golang uses gorm to set the primary key to increase automatically

When using GORM to operate a SQLite database in Golang, you can set the primary key to auto-increment by following the steps:

First, make sure that the GORM and SQLite drivers are installed. You can install them using the following command:

go get -u /gorm  
go get -u /driver/sqlite

Import the required packages:

import (  
    "/gorm"  
    "/driver/sqlite"  
)

Create a database connection:

db, err := ((""), &{})  
if err != nil {  
    // Handle errors}

Create a model (for example, a table called User):

type User struct {  
    ID   uint   `gorm:"primary_key;auto_increment"`  
    Name string `gorm:"not null"`  
}

In the model, the ID field is specified as primary_key and auto_increment, indicating that the field is the primary key and is automatically incremented.

Perform the operation of creating a table:

(&User{})

Now you can insert new records using GORM and automatically generate primary key values:

user := User{Name: "John Doe"}  
(&user)

After inserting the record, the automatically generated primary key value will be included.

This is a simple example showing how to set primary key increment using GORM and SQLite in Golang. You can adjust and expand according to your needs.
