MySQL return result by quantity per row -


i need query requires me return below.

data table -------------------------------- product name | quantity apple        | 3 egg          | 2  query expected result -------------------------------- product name apple apple apple egg egg 

thanks feedback

update #1 ok bad question unclear. want display result looping product quantity. expected result on quantity makes confusion. therefore, possible loop record quantity in mysql?

if need in sql can leverage tally(numbers) table, can create , populate values 1-100 so

create table tally(n int not null auto_increment primary key); insert tally (n) select a.n + b.n * 10 + 1 n   (select 0 n union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) ,(select 0 n union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) b order n; 

then query

select product_name   data_table d join tally t     on t.n <= d.quantity 

note: make sure have max(n) value in tally table >= max(quantity) in data_table work properly

output:

 +--------------+ | product_name | +--------------+ | apple        | | apple        | | apple        | | egg          | | egg          | +--------------+
