You Cannot Analyze a Table Through a Synonym

This was tested on an Oracle 11 database. First I created a table and analyzed it: 

SQL> create table andrew1 (one_col number)
  2  /

Table created.

SQL> analyze table andrew1 compute statistics
  2  /

Table analyzed.


Then I created a synonym for the table:

SQL> create synonym andrew2 for andrew1
  2  /

Synonym created.


I found that I was able to describe the table via the synonym:

SQL> desc andrew2
 Name                    Null?    Type
 ----------------------- -------- ----------------
 ONE_COL                          NUMBER


... but I could not analyze it:

SQL> analyze table andrew2 compute statistics
  2  /
analyze table andrew2 compute statistics
ERROR at line 1:
ORA-00942: table or view does not exist
