SQL Min

🎯 한 줄 통찰 (One-line insight)

MIN() returns the smallest value in a column across numeric, string, or date types, and its unnamed result column typically needs an alias. [S1]

🧠 핵심 개념 (Core concepts)

  • MIN() function — returns the smallest value of the selected column; works with numeric, string, and date data types. [S1]
  • SyntaxSELECT MIN(column_name) FROM table_name WHERE condition;. [S1]
  • Unnamed result — MIN()'s returned column has no name by default; use AS to give it a descriptive alias. [S1]
  • MIN() with GROUP BY — returns the smallest value per group, e.g. lowest price per category. [S1]

📖 세부 내용 (Details)

  • Lowest price: SELECT MIN(Price) FROM Products;. [S1]
  • With alias: SELECT MIN(Price) AS SmallestPrice FROM Products;. [S1]
  • On a date column: SELECT MIN(BirthDate) AS EarliestBirthdate FROM Employees;. [S1]
  • With GROUP BY: SELECT MIN(Price) AS SmallestPrice, CategoryID FROM Products GROUP BY CategoryID;. [S1]
