Query ultimos 12 meses

[vitorweb 2]

Olá, tenho a seguinte Query SQL:

SELECT DISTINCT EXTRACT(YEAR_MONTH FROM date) AS data, SUM(price) AS totalPrice FROM sys_constructions_finance WHERE id_construction = ? GROUP BY data;

Preciso adequar a mesma para que exiba somente os registros dos ultimos 12 mêses de registros a partir do dia atual.

Obrigado.
