Dependencies on Synonyms

Question

Is it at all possible to find out which objects (views, function, procedures, ...) are using a specific synonym? If yes, where and how can I extract this information? I am using Oracle 10g R2. Thanks a lot for your help!

Hi and welcome to the forum.
You can query on of the following 3 datadictionary views:
USER_SYNONYMS
ALL_SYNONYMS
DBA_SYNONYMS
SQL> desc user_synonyms
Name                            Null?    Type
SYNONYM_NAME                    NOT NULL VARCHAR2(30)
TABLE_OWNER                              VARCHAR2(30)
TABLE_NAME                      NOT NULL VARCHAR2(30)
DB_LINK                                  VARCHAR2(128)
SQL> desc all_synonyms
Name                            Null?    Type
OWNER                           NOT NULL VARCHAR2(30)
SYNONYM_NAME                    NOT NULL VARCHAR2(30)
TABLE_OWNER                              VARCHAR2(30)
TABLE_NAME                      NOT NULL VARCHAR2(30)
DB_LINK                                  VARCHAR2(128)
SQL> desc dba_synonyms
Name                            Null?    Type
OWNER                           NOT NULL VARCHAR2(30)
SYNONYM_NAME                    NOT NULL VARCHAR2(30)

Actually Anurag's reply is probably better advice ;)
