mysql - How do i join 2 queries? - 


select a.nume_echipament,        a.producator,        a.seria,        b.uc,        b.port ,            a.durata_aprovizionare durata_aprovizionare,       ( select  sec_to_time(count(starea)*5) echipamente inner join aprovizionari on  echipamente.nume_echipament=aprovizionari.nume_echipament  ( echipamente.ora>aprovizionari.ora_aprov , echipamente.data>aprovizionari.data_aprov) , starea='1' ,  echipamente.nume_echipament='automat_imbuteliere') durata_functionare,        a.durata_viata durata_viata,       ( select data_aprov aprovizionari nume_echipament='automat_imbuteliere' order date(data_aprov) desc, time(ora_aprov) desc limit 1) data_aprov,       ( select ora_aprov aprovizionari nume_echipament='automat_imbuteliere' order date(data_aprov) desc, time(ora_aprov) desc limit 1) ora_aprov,       (select sec_to_time(count(starea)*5)) durata_totala          date_tehnice        inner join echipamente b on a.nume_echipament=b.nume_echipament        inner join aprovizionari c on c.nume_echipament=a.nume_echipament        a.nume_echipament='automat_imbuteliere'        ,        b.starea='1';

the above query work fine, need result query

select `starea` echipamente nume_echipament='automat_imbuteliere' order data desc, ora desc limit 1 ;

as can see in first query depends on b.starea='1', whereas second query needs latest value of 'starea'. 'starea' has 0 , 1 values. so, how combine 2 queries 1 query in order last value value of 'starea'?

to second query have own row union them many null columns needed match number of columns in first query.

union select  (select `starea` echipamente nume_echipament='automat_imbuteliere' order data desc, ora desc limit 1 ) , null , null , null  , null  , null
