PL/SQL Copy Table: Structure & Data Methods

In PL/SQL, there are two ways to copy the structure and data of a table:

1. 使用CREATE TABLE AS SELECT语句
   这种方法可以通过SELECT语句选择源表的所有行，并将结果插入到新创建的目标表中。语法如下：
2. Create a new table named new_table by selecting all the data from source_table.
3. The above statement will create a new table called new_table with the same structure as source_table and copy all the data from source_table into new_table.
4. The INSERT INTO SELECT statement allows you to select specific rows from a source table and insert them into an existing target table. The syntax is as follows:
5. Add all the data from the source table into the target table.
6. The statement mentioned above will insert all data from the source_table into the target_table, assuming that the target_table already exists and has the same structure as the source_table.

It should be noted that both of these methods only copy the structure and data of the table, excluding indexes, constraints, triggers, and other objects. If you need to copy these objects, you can use tools provided by Oracle, such as Oracle SQL Developer or PL/SQL Developer.
