一、更新跟进人姓名

UPDATE g_ec_customer
SET follow_user_name = (
    CASE follow_user_id
    WHEN '6582553' THEN
        '廖梓秀'
    WHEN '6582564' THEN
        '刘琪燕'
    WHEN '6624924' THEN
        '陈欣蕾'
    WHEN '6624972' THEN
        '袁良'
    WHEN '7166053' THEN
        '刘虎'
    WHEN '7166071' THEN
        '林龙飞'
    WHEN '7166183' THEN
        '陈利国'
    WHEN '7240909' THEN
        '方垒'
    WHEN '7240941' THEN
        '汪开胜'
    WHEN '7360237' THEN
        '李娜'
  WHEN '7360262' THEN
        '程会子'
    END
);

二、创建客户表的对比表

CREATE TABLE g_ec_dist AS (
    SELECT
        t.follow_user_name,
        t.crm_id,
        t.`name`,
        t.mobile,
        t.create_time
    FROM
        g_ec_customer t
    WHERE
        t.create_time <= '2018-04-30 23:59:59'
    AND t.follow_user_name != ''
    AND t.follow_user_name IS NOT NULL 
    ORDER BY
        t.follow_user_name,
        t.create_time
);

三、查询重复客户（总）

SELECT
    t.follow_user_name,
    t.crm_id,
    t.`name`,
    t.mobile,
    t.create_time,
    t2.follow_user_name,
    t2.crm_id,
    t2.`name`,
    t2.mobile,
    t2.create_time
FROM
    g_ec_customer t, g_ec_dist t2
WHERE t.`name` = t2.mobile
AND t.create_time != t2.create_time
AND t.create_time <= '2018-04-30 23:59:59'
AND t.follow_user_name != ''
AND t.follow_user_name IS NOT NULL
AND t.follow_user_name != t2.follow_user_name
ORDER BY t.follow_user_name,t.create_time;

四、查询重复客户（五人）

SELECT
    t.follow_user_name,
    t.crm_id,
    t.`name`,
    t.mobile,
    t.create_time,
    t2.follow_user_name,
    t2.crm_id,
    t2.`name`,
    t2.mobile,
    t2.create_time
FROM
    g_ec_customer t, g_ec_dist t2
WHERE t.`name` = t2.mobile
AND t.create_time != t2.create_time
AND t.create_time <= '2018-04-30 23:59:59'
AND t.follow_user_name != ''
AND t.follow_user_name IS NOT NULL
AND t.follow_user_name != t2.follow_user_name
AND (t.follow_user_name IN ('方磊','汪开胜','陈立国','刘虎','林龙飞') OR t2.follow_user_name IN ('方磊','汪开胜','陈立国','刘虎','林龙飞'))
ORDER BY t.follow_user_name,t.create_time;
