ERROR 1066: Not unique table/alias: "A"

Hello!

Following insert works on Oracle 7,8,9 and MS SQLServer 6,7,2000 (without
'TYPE=INNODB').
Is it posible to get MySQL to understand this insert also?

Version used:
D:\mysql\bin>mysqld-max-nt.exe -V
mysqld-max-nt.exe Ver 4.1.0-alpha-max-nt for NT on i32

---
mysql> DROP TABLE IF EXISTS A;
Query OK, 0 rows affected (0.00 sec)

mysql> CREATE TABLE A (a1 INT) TYPE=INNODB;
Query OK, 0 rows affected (0.00 sec)

mysql> INSERT INTO A (a1) VALUES (1);
Query OK, 1 row affected (0.00 sec)

mysql> COMMIT;
Query OK, 0 rows affected (0.00 sec)

mysql> SELECT * FROM A;
+------+
| a1 |
+------+
| 1 |
+------+
1 row in set (0.00 sec)

mysql> INSERT INTO A (a1) SELECT max(a1)+1 FROM A;
ERROR 1066: Not unique table/alias: 'A'

This feature were recently implemented in 4.0.15 and merged to 4.1 tree. This
happened after 4.1.0 was released.

4.1.1 which will be released soon has it.

Yes!
Actually, MySQL understands it now, in the 4.1 development tree.
It was implemented after 4.1.0 release.
So your query will work in 4.1.1.
