Question

I have table A and table B. Both of them have the same fields. If Table B has new data, I would like do complete update on Table A from Table B. It’s complete replacement. or clone the data from Table B to table A

So, I have the sql as followed.

sql="update `table A` select * from `table B`"

I executed that but it didn’t give me the right result.

what should be the right sql?

Answer 1

If you want to create a copy of table B, you can do this with

CREATE TABLE A SELECT * FROM B
