MySQL select column name as field

Question

I have a mysql table that looks something like this:

id | col_1 | col_2 | col_3
---|-------|-------|------
1  | 2     | 34    | 64
2  | 6     | 53    | 23
         


        

Answer 1

You could do it like this, this will return to you 2 comma separated first one of columns second of values, which you can explode and merge into KEY/VALUE arrays in PHP.

SELECT 
    GROUP_CONCAT(COLUMN_NAME) AS _columns,
    (SELECT 
            GROUP_CONCAT(columnName, ',', columnName)
        FROM table_name
        WHERE id = 1)
FROM
    information_schema.columns
WHERE
    table_name = 'table_name'
        AND COLUMN_NAME IN ('columnName' , 'columnName');
