# [[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]
- **Syntax** — `SELECT 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]

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — MAX()와 짝을 이뤄 범위(최소~최대) 리포트에 자주 함께 쓰인다. [S1]

## 💻 코드 패턴 (Code patterns)
MIN with alias and GROUP BY (SQL):
```sql
SELECT MIN(Price) AS SmallestPrice, CategoryID
FROM Products
GROUP BY CategoryID;
```
