How can I manage transactions in Go using the SQL package?

You can manage transactions in Go by using the Begin, Commit, and Rollback methods from the database/sql package.

Can you provide a code example for starting a transaction?

Sure! Here's a simple example:

package main

import (
    "database/sql"
    _ "github.com/lib/pq"
    "log"
)

func main() {
    db, err := sql.Open("postgres", "user=username dbname=mydb sslmode=disable")
    if err != nil {
        log.Fatal(err)
    }
    
    tx, err := db.Begin()
    if err != nil {
        log.Fatal(err)
    }
    
    // Perform database operations here
    
    if err := tx.Commit(); err != nil {
        log.Fatal(err)
    }
}

What happens if I encounter an error during the transaction?

If an error occurs, you should call tx.Rollback() to revert any changes made during the transaction.

Is it possible to nest transactions in Go?

Go's database/sql package does not support nested transactions directly, but you can manage them using savepoints.
