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):
SELECT * FROM Products
WHERE Price BETWEEN 10 AND 20;
Date range (SQL):
