SET name = 'Unknown'  
WHERE name IS NULL OR name = '';

UPDATE movr.max_schema.users 
SET credit_card = '0000000000'  
WHERE credit_card IS NULL OR credit_card = '';

UPDATE movr.max_schema.users
SET address = 'Not Available'  
WHERE address IS NULL OR address = '';

Step 5: Perform Data Analysis

After cleaning, analyze the consistent data using SQL statements such as JOIN, WHERE, ORDER BY, and GROUP BY. To conduct an in-depth analysis, utilize subqueries, common table expressions (CTEs), window functions, and pivot tables. CockroachDB's vectorized execution engine significantly improves performance for complex analytical queries.
