Here is an example of a query to retrieve all rows from a table called 'Customers':
This query will return all columns and rows from the 'Customers' table.
The query can also be used to filter the data, for example to return only customers from the state of California:
WHERE state = 'CA';
This query will return all columns and rows from the 'Customers' table where the
state column has a value of
You can also use RSQL to join multiple tables together, for example to join the 'Customers' table with the 'Orders' table:
SELECT c.name, o.order_total
FROM Customers c
JOIN Orders o
ON c.customer_id = o.customer_id;
This query will return the
name column from the 'Customers' table and the
order_total column from the 'Orders' table, where the
customer_id from both tables match.
