Krijg kolomnaam dynamisch op specifieke rijwaarde

set @q= CONCAT('SELECT columns.column_name 
                from table inner 
                join information_schema.columns 
                on columns.table_schema = "dbname" 
                and columns.table_name = "table" 
                and ((',
                (SELECT GROUP_CONCAT(CONCAT('columns.column_name="',column_name,'"',' and table.',column_name,' = "value','"') SEPARATOR ' OR ')
                FROM INFORMATION_SCHEMA.COLUMNS 
                WHERE table_name = 'table'),
                '))');
prepare query from @q;
execute query;

Dit werkt zeker..
