Tengo este query
Código PHP:
SELECT mos_ap_contact.id, mos_ap_contact.first_name, mos_ap_contact.last_name, mos_ap_contact.company_name, mos_ap_type.description AS
TYPE , mos_ap_city.description AS city, mos_ap_state.description AS state
FROM mos_ap_contact
LEFT JOIN mos_ap_city ON mos_ap_contact.id_city = mos_ap_city.id
LEFT JOIN mos_ap_state ON mos_ap_contact.id_state = mos_ap_state.id
LEFT JOIN mos_ap_category_contact ON mos_ap_contact.id = mos_ap_category_contact.id_contact
LEFT JOIN mos_ap_category ON mos_ap_category_contact.id_category = mos_ap_category.id
LEFT JOIN mos_ap_type ON mos_ap_contact.id_type = mos_ap_type.id
WHERE 1 =1
AND mos_ap_contact.id_type = '1'
AND mos_ap_contact.erased = '0'
ORDER BY mos_ap_contact.id ASC
LIMIT 0 , 200
¿Qué podria ocasionar la duplicidad de datos?
