Oracle AS keyword prompt Error

When running the program today, enter the SQL statement in Oracle:Select * from USERSAsUProgram error

InputSelect * from USERS uYou can query the results normally.

However, in SQL Server 2005, enter''Select * from USERSAsU''There is no error in the same statement. The reason is AS follows: SQL2 allows the keyword AS to appear between the table name and the table alias. Although this makes the FROM clause easier to understand, however, it may not be supported in a specific SQL product.

I think Oracle does not support this syntax.
