# Updating an SQL table
|
|
|
|
We use the `ALTER` query to add, remove and otherwise change the structural
|
|
properties of a table in the database.
|
|
|
|
## Add an additional field to existing table
|
|
|
|
This adds a `price` field to the `sales` table. The `price` field accepts data
|
|
of the type `real`.
|
|
|
|
```sql
|
|
ALTER TABLE sales ADD price real;
|
|
```
