# Reading Variables

To retrieve the value of a variable, use the `@@` selector with the variable in a `SELECT` statement. For example,

```sql
SELECT @@sql_mode;

```

```output

+-------------------+
| @@sql_mode        |
+-------------------+
| STRICT_ALL_TABLES |
+-------------------+
1 row in set (0.27 sec)

```
