sql 查询 select 记录具有相同的 id 但在两列中的值不同

Question

I tried for hours and read many posts but I still can't figure out how to handle this request

I have a table like this

Name        Phone

John        62778282
Alok        67828888
Rahul       68999999
Yash        97788899
John        99989999
Rahul       99992222

The output should be something like:

Name        Phone

John        62778282 , 99989999
Alok        67828888
Rahul       68999999 , 99992222
Yash        97788899

Please Anybody help me to get this result

Answer 1

In this case you could use GROUP_CONCAT with GROUP BY:

SELECT 
    `Name`,
    GROUP_CONCAT(`Phone`) AS `Phone`
FROM `Table`
GROUP BY `Name`;

Result SQL query

| Name  | Phone             |
+=======+===================+
| Alok  | 67828888          |
| John  | 62778282,99989999 |
| Rahul | 62778282,99992222 |
| Yash  | 97788899          |
