SELECT INTO using Oracle

问题

I\'m trying to do a SELECT INTO using Oracle. My query is:

SELECT * INTO new_table FROM old_table;

But I get the following error:

SQL Error: ORA-00905: missing keyword
00905. 00000 -  \"missing keyword\"

Any ideas what\'s wrong?

The Standard behavior of the above should be as I originally thought: However Oracle implemented it totally differently in their own dialect of SQL Oracle Docs on Insert ... Select

回答1:

If NEW_TABLE already exists then ...

insert into new_table select * from old_table
/

If you want to create NEW_TABLE based on the records in OLD_TABLE ...

create table new_table as select * from old_table
/

回答2:

select into is used in pl/sql to set a variable to field values. Instead, use

create table new_table as select * from old_table

回答3:

Use:

create table new_table_name 
as
select column_name,[more columns] from Existed_table;

Example:

create table dept
as
select empno, ename from emp;

If the table already exists:

insert into new_tablename select columns_list from Existed_table;
