## SQL en el operador

## Operador IN definido

El operador `IN` se utiliza en un `WHERE` o `HAVING` (como parte de `GROUP BY` ) para limitar las filas seleccionadas a los elementos "IN" de una lista.

Aquí está la lista completa actual de estudiantes para comparar con el conjunto de resultados de la cláusula `WHERE` :

```sql
select studentID, FullName, sat_score, rcd_updated from student; 
```

```text
+-----------+------------------------+-----------+---------------------+ 
 | studentID | FullName               | sat_score | rcd_updated         | 
 +-----------+------------------------+-----------+---------------------+

Se presentarán las filas que tienen un puntaje SAT en esta lista (1000, 2400):

```sql
select studentID, FullName, sat_score, rcd_updated 
 from student
