Extract Unique sap_article_id Values from Duplicate Dataset

Got it, let's break down how to pull out the unique sap_article_id values from your duplicate-heavy list. The approach depends on the tool you're using—here are the most common solutions:

1. SQL (Database Query)

If you're working directly with a database table that contains these IDs, use the DISTINCT keyword to eliminate duplicates in one go:

SELECT DISTINCT sap_article_id
FROM your_table_name;

Alternatively, you can use GROUP BY to achieve the same result (this is handy if you later want to add aggregate functions like counting duplicate occurrences):

SELECT sap_article_id
FROM your_table_name
GROUP BY sap_article_id;

Both queries will return the three unique IDs from your dataset: 100262, 136151, 141933.

2. Python (Processing a List of IDs)

If you have the IDs stored as a Python list, use a set to automatically remove duplicates. Note that sets are unordered—if you need to preserve the original order of first occurrence, use dict.fromkeys() instead:

# Your full list of sap_article_id values
sap_id_list = [100262, 100262, 100262, 136151, 141933, ...]

# Fast unordered deduplication
unique_ids = list(set(sap_id_list))

# Preserve original order (works in Python 3.7+)
unique_ids_ordered = list(dict.fromkeys(sap_id_list))
