What Objects are Dependent?
What Objects are Dependent?
In Oracle, if you want to see all the tables used by a specific package, you can approach this task by querying the database's data dictionary views. The most relevant views for this task are ALL_DEPENDENCIES, DBA_DEPENDENCIES, or USER_DEPENDENCIES, depending on your access level and the scope of your search. These views can show you the dependencies between database objects.
Here’s a step-by-step guide on how you can see all tables used in a specific package:
You can use the USER_DEPENDENCIES view if you're only interested in objects owned by the current user, ALL_DEPENDENCIES if you have privileges to see across schemas, or DBA_DEPENDENCIES if you have DBA privileges.
SELECT name, type, referenced_owner, referenced_name, referenced_type
FROM all_dependencies
WHERE name = 'YOUR_PACKAGE_NAME'
AND type = 'PACKAGE'
AND referenced_type = 'TABLE';
If your package refers to tables through synonyms, you might need to resolve these synonyms to the actual table names. This can be done by joining with the ALL_SYNONYMS view:
SELECT d.name, d.type, d.referenced_owner, nvl(s.table_owner, d.referenced_owner) as real_owner,
nvl(s.table_name, d.referenced_name) as real_name, d.referenced_type
FROM all_dependencies d
LEFT JOIN all_synonyms s ON d.referenced_owner = s.owner
AND d.referenced_name = s.synonym_name
WHERE d.name = 'YOUR_PACKAGE_NAME'
AND d.type = 'PACKAGE'
AND d.referenced_type = 'TABLE';
The queries provided above assume you have the necessary permissions to query the respective views (ALL_DEPENDENCIES, DBA_DEPENDENCIES, or USER_DEPENDENCIES).
Keep in mind that if your package is executing dynamic SQL (constructing SQL queries as strings and executing them), this method won't catch those table references. Analyzing dependencies for dynamic SQL would require a more complex analysis, potentially involving parsing the package source code.
By following these steps, you should be able to retrieve a list of all tables that are used by a specific package in your Oracle database.
