Question

I have a database with two tables which are being merged into. Some fields are missing some fields mantain but they are in a new database.

One have ~263,975 rows and other ~134,533.

With that said, which could be the best method to do this?

I’ve thought about exporting to raw SQL and then alter the insert but seems to be a little bit rough for files of about 70 Mb that will crash almost any text editor…

Answer 1

The best method is:-

1. Write a query which- fetch only required field and required data from both tables, You can use JOIN or UNION and create a new table.
2. Export this new table.
3. Import this new table in new database.
