Oracle, SQL Server, MySQL replication table data

We know that the way to replicate table data in Oracle is to use

CREATE TABLE table_name AS SELECT * FROM table_name

This is not used in SQL Server.

The statements are as follows:

SELECT * into TABLE_NAME from TABLE_NAME;

And there are two ways in MySQL

1. Create Table A like B

2. Oracle-like approach

CREATE TABLE table_name AS SELECT * FROM table_name

There's a difference in how MySQL works

Use the Like method

This way, when you copy table B to a, the complete field structure and index of table B is copied to table A.

Using Oracle-like methods

This method only copies the field structure of Table B to table A, but does not copy the index from table B to table A. This is a flexible way to specify which fields you want to replicate while replicating the original table structure, and you can also add the field structure as needed by copying the table itself.

There are two ways to copy a table without copying the permissions on the table settings. For example, the permissions set for Table B, after replication, table A does not have permissions similar to Table B.
