## Ejemplo
|
|
|
|
```go
|
|
cols := []string{"name", "score", "ts"}
|
|
rows := [][]any{
|
|
{"Alice", 95.5, 1700000000},
|
|
{"Bob", 87.2, 1700000001},
|
|
{"Carol", 91.0, 1700000002},
|
|
}
|
|
n, err := DBInsertBatch(db, "results", cols, rows)
|
|
if err != nil {
|
|
return err
|
|
}
|
|
fmt.Printf("insertadas: %d filas\n", n)
|
|
```

## Notas
|
|
|
|
Usa `tx.Prepare()` + `stmt.Exec()` en un loop dentro de una transaccion. El rollback es automatico si alguna fila falla. Valida tabla y columnas con regex. Cada fila debe tener exactamente `len(columns)` valores — retorna error descriptivo si no coincide.
