Can I use a calculated field in a WHERE condition of a SELECT statement? I get a "column 'total' does not exist" error when I run the statement below. 'total' is a field generated by a SUM and I want to use it in the WHERE condition.
SELECT
facturas.fce_id,
facturas.fce_numero_factura,
facturas.fce_fecha,
compradores.com_nombre,
facturas.fce_subdivision,
facturas.fce_valor_comercial,
SUM(facsub.fce_valor_comercial) AS total
FROM
trafico.facturas_exportacion facturas
INNER JOIN trafico.cat_compradores compradores ON (facturas.fce_comprador = compradores.com_clave)
INNER JOIN trafico.facturas_exportacion facsub ON (facturas.fce_id = facsub.fce_id_factura_original)
WHERE
facturas.fce_subdivision = true AND facturas.fce_valor_comercial > total
