This compiler simplifies complex SQL with pipe syntax, enabling step-by-step query building that auto-generates native SQL. It includes a checker for readability, performance tips, and diagnostics to catch errors, making SQL writing and maintenance effortless.

Example:

with pipe syntax:

```sql

FROM orders

|> JOIN customers ON orders.customer_id = customers.customer_id

|> WHERE orders.total_amount > (SELECT AVG(total_amount) FROM orders)

|> AGGREGATE COUNT(order_id) AS num_orders

GROUP BY customers.customer_name;

```

to native SQL:

```sql

SELECT COUNT(orders.order_id) AS num_orders

FROM orders

JOIN customers ON orders.customer_id = customers.customer_id

WHERE orders.total_amount > (SELECT AVG(total_amount) FROM orders)

GROUP BY customers.customer_name;

```

with pipe syntax:

```sql

FROM employees

|> JOIN departments ON employees.dept_id = departments.id

|> WHERE employees.salary > 50000

|> ORDER BY employees.salary DESC

LIMIT 5;

```

to native SQL:

```sql

SELECT *

FROM employees

JOIN departments ON employees.dept_id = departments.id

WHERE employees.salary > 50000

ORDER BY employees.salary DESC

LIMIT 5;

```
