# **Introduction:**

As a data analyst, adapting to business logic changes often necessitates modifications to stored procedures within Oracle databases. The initial step in this adaptation process is to accurately identify the specific stored logic associated with the target tables. This article addresses this key requirement by outlining effective methods to pinpoint and understand the stored procedures linked to any given table in an Oracle environment.

## **Understanding Oracle Source Views:**

Oracle offers several views for examining the source code of stored objects:

1. **ALL_SOURCE**: Shows text source for stored objects accessible to the current user, useful for developers.
2. **DBA_SOURCE**: Provides text source for all database stored objects, accessible only to administrators.
3. **USER_SOURCE**: Displays text source for objects owned by the current user, omitting the OWNER column as the user context is assumed.

# Searching for Stored Procedures:

To effectively manage stored procedures, it is essential to know how to locate them, especially when trying to understand which procedures interact with specific tables. Below are two useful SQL queries for these purposes:

### **Finding Which Procedures Reference a Specific Table:**

To find out which stored procedures refer to a particular table, you can use the following SQL query. This is particularly useful when you are trying to determine the impact of changes to a table structure or debugging issues related to specific data manipulations.

```sql
SELECT DISTINCT * FROM dba_source
WHERE TYPE = 'PROCEDURE' AND UPPER(text) LIKE '%Table_Name%';
```

This query searches the **`DBA_SOURCE`** for any procedure that contains a reference to **`Table_Name`**. Replace **`Table_Name`** with the actual name of the table you are interested in.

### **Identifying Tables Involved in a Procedure:**

If you need to understand which tables a specific procedure interacts with, the following SQL query can be invaluable:

```sql
SELECT name, type, referenced_owner, referenced_name, referenced_type
  FROM user_dependencies
WHERE TYPE='PROCEDURE' AND NAME LIKE '%PROCEDURE_NAME%';
```

This query examines the **`USER_DEPENDENCIES`** view to list all the tables (and other objects) that a given procedure depends on. Replace **`PROCEDURE_NAME`** with the name of the procedure you are researching.

# Conclusion:

This guide offers a practical approach for data analysts who need to adapt Oracle database procedures in response to changes in business logic. By utilizing specialized views and SQL queries, analysts can efficiently locate and revise the underlying stored logic of target tables. This capability not only streamlines routine updates but also enhances the overall integrity and performance of database operations, empowering professionals to manage complex data environments more effectively.
