# [[SQL Between]]

## 🎯 한 줄 통찰 (One-line insight)
BETWEEN selects values within an inclusive range — numbers, text (alphabetical range), or dates — and can be negated with NOT BETWEEN or combined with IN. [S1]

## 🧠 핵심 개념 (Core concepts)
- **BETWEEN operator** — selects values within a specified range; the range is inclusive of both boundary values. [S1]
- **Syntax** — `SELECT column_name(s) FROM table_name WHERE column_name BETWEEN value1 AND value2;`. [S1]
- **NOT BETWEEN** — selects values outside the specified range. [S1]
- **Value types** — works with numbers, text (alphabetical ordering), and dates. [S1]

## 🧩 추출된 패턴 (Extracted patterns)
- **BETWEEN + IN combo** — `WHERE Price BETWEEN 10 AND 20 AND CategoryID IN (1,2,3);` layers a range filter with a set-membership filter. [S1]
- **Date format discipline** — date BETWEEN comparisons require the literal format to match the database's date format convention (e.g. `'YYYY-MM-DD'`). [S1]

## 📖 세부 내용 (Details)
- Numeric range: `SELECT * FROM Products WHERE Price BETWEEN 10 AND 20;`. [S1]
- Negated numeric range: `WHERE Price NOT BETWEEN 10 AND 20;`. [S1]
- Text (alphabetical) range: `WHERE ProductName BETWEEN 'Geitost' AND 'Louisiana Hot Spiced Okra' ORDER BY ProductName;`. [S1]
- Date range: `WHERE OrderDate BETWEEN '1996-07-01' AND '1996-07-31';` selects orders placed in July 1996. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
소스에서 모순되는 정보는 발견되지 않음.

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — 가격 범위 필터, 날짜 범위 리포트 등 실무 쿼리에서 흔히 재사용되는 패턴이다. [S1]

## 💻 코드 패턴 (Code patterns)
Numeric range (SQL):
```sql
SELECT * FROM Products
WHERE Price BETWEEN 10 AND 20;
```
Date range (SQL):
```sql
SELECT * FROM Orders
WHERE OrderDate BETWEEN '1996-07-01' AND '1996-07-31';
```
