got the solution and will get the colnames using the below query.
dbGetQuery(con,"SELECT column_name
+ FROM information_schema.columns
+ WHERE table_schema = 'your schema'
+ AND table_name = 'table name'") ##ORDER BY ordinal_position; to orderby
sample query :
dbGetQuery(con,"SELECT column_name, data_type
+ FROM information_schema.columns
+ WHERE table_name = 'data 1'
+ ORDER BY ordinal_position")
Both query's are working good.
