oracle11g - Alter table after keyword in Oracle

Question

ALTER TABLE testTable ADD column1 NUMBER(1) DEFAULT 0 NOT NULL AFTER column2;

Why can't I use mySql syntax in Oracle too? The above command works in MySql. Can you give me an equivalent that works?

Error report:
SQL Error: ORA-01735: invalid ALTER TABLE option
01735. 00000 -  "invalid ALTER TABLE option"

I am asking if there is any way to use after clause in Oracle command that I provided?

Answer 1

Because SQL is a relational algebra. It doesn't care one bit about "where" columns are located within a table, only that they exist.

To get it to work in Oracle, just get rid of the after clause. The Oracle documentation for alter table is here but it boils down to:

alter table testTable
    add ( column1 number(1) default 0 not null )

There is no after clause for the alter table command.
