# [[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]

|
|
|
## 🛠️ 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';
|
|
```
