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
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 /
If the purpose is to create a new but empty table then use a WHERE clause with a condition which can never be true:
create table new_table as select * from old_table where 1 = 2 /
Remember that CREATE TABLE … AS SELECT creates only a table with the same projection as the source table. The new table does not have any constraints, triggers or indexes which the original table might have. Those still have to be added manually (if they are required).
