How to find out where a table is used in the code ?

Question

I have a huge database, and I am adding a column to a table...
is there a query to find out if this would impact the code ? I mean I want to find all the places in the code with
insert into mytable, or update mytable.....
how to include both insert into mytable, and update mytable in dba_source ?

Answer 1

Use DBA_DEPENDENCIES:
select owner,name,type from dba_dependencies where referenced_name = 'TABLE_NAME'
and referenced_owner = 'TABLE_OWNER';For example:
SQL> select owner,name,type from dba_dependencies where referenced_name = 'EMP'
  2  and referenced_owner = 'SCOTT';
OWNER                          NAME                           TYPE
PUBLIC                         TABLE1                         SYNONYM
SCOTT                          SELECT_EMP                     PROCEDURE
SCOTT                          EMP_DEPT_VW                    VIEW
SCOTT                          PP                             SYNONYM
SCOTT                          EMP_MV                         MATERIALIZED VIEW
SCOTT                          EMP_VIEW                       VIEW
6 rows selected.
SQL> However, keep in mind DBA_DEPENDENCIES stores statis references only. If your code references table in question in dynamic SQL you will have to parse DBA_SOURCE and in some cases, even that will not give you all answers.
