The query returned zero results, confirming that every row in the 37,620-row dataset is unique.\n\n**What this means:**\n- Each player record (identified by the combination of all attributes: Player ID, Name, Assoc, Gender, Birth year, Activity, Playing hand, Playing style, Grip, and metadata fields) appears exactly once\n- There are no data quality issues from accidental row duplication\n- The Player ID field likely serves as a natural unique identifier\n\n**Note on near-duplicates:** This analysis checked for *exact* duplicates only. Near-duplicates (e.g., same player with slightly different spellings, or records that differ only in metadata timestamps) would require fuzzy matching on specific columns like Name or a subset of attributes. If you're concerned about near-duplicates in particular fields, I can investigate those specifically."
