sql server - Duplicating rows based on a column value in each row -


i've table following data

job    quantity status repeat 1      100      ok     2 2      400      hold   0 3      200      hold   1 4      450      ok     3

based on value in repeat column each row, row should repeated again. example job 1, repeat value 2 job 1 should repeat 2 more times.

the resultant table should below

job    quantity status repeat 1      100      ok     2 1      100      ok     2 1      100      ok     2 2      400      hold   0 3      200      hold   1 3      200      hold   1 4      450      ok     3 4      450      ok     3 4      450      ok     3 4      450      ok     3

i'm using sql server

this support on 7,400 repeats individual job (on system). if need more, can use different system table or cross join.

declare @d table (job int, quantity int, status varchar(12), repeat int);  insert @d select 1, 100, 'ok'  ,2 union select 2, 400, 'hold',0 union select 3, 200, 'hold',1 union select 4, 450, 'ok'  ,3;  x  (   select top (select max(repeat)+1 @d) rn = row_number()    on (order [object_id])    sys.all_columns    order [object_id] ) select * x cross join @d d x.rn <= d.repeat + 1 order job;
