How do I handle transactions using the Go SQL driver?

To handle transactions in Go using the SQL driver, you can use the Begin() method to start a transaction.

Can you show me a code example?

Sure! Here's a simple example:

package main

import (
    "database/sql"
    _ "github.com/go-sql-driver/mysql"
)

func main() {
    db, err := sql.Open("mysql", "user:password@/dbname")
    if err != nil {
        log.Fatal(err)
    }
    
    tx, err := db.Begin()
    if err != nil {
        log.Fatal(err)
    }
    
    // Perform your database operations here
    
    if err := tx.Commit(); err != nil {
        tx.Rollback()
        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?

No, the Go SQL driver does not support nested transactions. You need to manage them manually.
