I would do
select * into mynewtable from myoldtable ORDER by random() LIMIT 15000
where 15000 in this case is <your table row count>*.6
If you want to create another table with 40% of the remaining data then something like
select * into mynewtable2 from myoldtable where myoldtable.primarykey NOT IN(select primarykey from mynewtable)
]
In this case primarykey you would replace with the primary key field of your table.
Hi,
I want to split a table to 2 small tables. The 1st one contains 60% records which are randomly selected from the source table.
How to do it?
Regards,
Felix
