Repetitions in MYSQL -


following mysql query, i'm hoping repeat data in result. i've tried union , throws syntax error.

select attribute_name attribute (select attribute_id platform_metadata_map );

any appreciated !

this wrong beacuse 

select attribute_name  attribute  (select attribute_id platform_metadata_map );

the clause don't match (you shoudl use attribute_id = (select ....)) anyway want repeat should repet teh query using union 

select attribute_name  attribute  union  select attribute_name  attribute  union select attribute_name  attribute  union  select attribute_name  attribute
