About

• History:
  • 2009-07-09 moved to separate wiki page; no design changes
  • 2011-11-23 added WhenEnt, WhenUpd
• Notes:
  • (2011-11-23) Possibly WhenUpd should be removed and replaced with one or both of:
    • WhenCnf (when confirmed) -- stamp whenever a new order is received that contains this email
    • WhenEdt (when edited) -- stamp whenever an admin saves the record

    same for Template:L/vc/table and Template:L/vc/table

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
