Utility
SQL query to get a list of cust records with multiple names:
SELECT
g.*, n.Name
FROM
(SELECT
c.ID, COUNT(n.ID) AS NameCount, GROUP_CONCAT(n.ID) AS NameIDs
FROM
cust_names AS n
LEFT JOIN cust AS c ON n.ID_Cust = c.ID
GROUP BY c.ID
HAVING COUNT(n.ID) > 1) AS g
LEFT JOIN
cust_names AS n ON g.ID = n.ID_Cust
WHERE
n.ID IS NOT NULL
ORDER BY g.ID
