## Ejemplo
|
|
|
|
```go
|
|
n, err := DBExec(db, "UPDATE users SET active = ? WHERE last_login < ?", false, cutoff)
|
|
if err != nil {
|
|
return err
|
|
}
|
|
fmt.Printf("desactivados: %d usuarios\n", n)
|
|
```

## Notas
|
|
|
|
Agnóstica al driver. Para DDL algunos drivers retornan 0 en RowsAffected — esto es normal. Para INSERT con last_insert_id usar `DBInsertRow` que retorna ese valor. Para multiples filas en una transaccion usar `DBInsertBatch`.
