ORA-00933 on table alias introduced with the AS keyword

Question

Oracle 10g is unable to parse the following query:
SELECT ALL "COUNTRY"."C_NAME" AS "NAME" FROM "C_COUNTRY" AS "COUNTRY";
However, the following query parses and executes all right:
SELECT ALL "COUNTRY"."C_NAME" AS "NAME" FROM "C_COUNTRY" "COUNTRY";
It seems that a correlation name (a table alias) cannot be preceded by the AS keyword. IIRC the SQL standard allows this so I am very surprised.

Answer 1

I stand corrected. Ingres does support "AS" to alias the table name:
* select ALL "S"."CODE" FROM "SECURITY_CODES" AS "S"\g
