'How to get distinct values from a column with all its corresponding values in another column
I have a table
table_categories (id INT(11), cname VARCHAR(25),survey_id INT(11))
I want to retrieve the values for the column cname without duplication, that is distinct values but with all the values in the other column.
id cname survey_id

From the above example I want to retrieve distinct cnames with all the values of the survey_id. I don't want to use any programming language. Is there any way by using a single query. Please give me a solution in MySQL.

You could use group_concat
SELECT cname, GROUP_CONCAT(survey_id) as survey_ids
FROM categories
GROUP BY cname
