# Reading data from SQL

Let's say, we need to display order total amount on `Customer` table for each customer. All Orders we stored in the separate `Orders` table in the SQL database. 

The result`Customers`table contains: `customer_id`, `photo`, `name`, `total_amount`columns of data for each customer.

### Build SQL query using SQL Builder

```sql
select 
(select sum(amount) from orders where customer_id = customerscrm.id) as total_amount,
id,
photo,
name
from 
customerscrm
```
