import ( "github.com/jinzhu/gorm" _ "github.com/jinzhu/gorm/dialects/postgres" ) func main() { db, err := gorm.Open("postgres", "user=postgres password=postgres dbname=mydb sslmode=disable") if err != nil { panic("Failed to connect to database") } // Use the DBSet to execute a query and get the results var users []User db.Where("age > ?", 18).Find(&users) }In this example, we create a new DBSet object using the Open() function, passing in the database connection details as a string argument. We then use the Where() and Find() methods to execute a query on the database and retrieve a list of user objects where the age is greater than 18. Overall, the gorm package is a powerful and flexible ORM library for working with SQL databases in Go. By using the DB Set functionality, you can easily create and manage database connections and execute queries with ease, making your database operations more efficient and streamlined.
