this is my query -
select distinct * from
-
(select distinct city,itm__code,barcode1 from bx_itembarcodemaster
-
where city = 'jhb'
-
and (barcode1 is not null and bqty1 is not null)
-
) jhb
-
left join
-
(
-
select distinct city,itm__code,barcode1 from bx_itembarcodemaster
-
where city = 'cpt'
-
and (barcode1 is not null and bqty1 is not null)
-
) cpt on cpt.itm__code = jhb.itm__code
-
left join
-
(
-
select distinct city,itm__code,barcode1 from bx_itembarcodemaster
-
where city = 'dbn'
-
and (barcode1 is not null and bqty1 is not null)
-
) dbn on dbn.itm__code = jhb.itm__code
-
and this is the result set -
JHB 0-16040 0-16040 CPT 0-16040 0-16040 DBN 0-16040 0-16040

Happy Coding!!!
