+# [[PHP MySQL Select Limit]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+`LIMIT 15, 10` and `LIMIT 10 OFFSET 15` return the IDENTICAL result, but the numbers are REVERSED between the two forms — the comma syntax puts the offset first and count second, while the OFFSET keyword syntax puts count first and offset second, a subtle inversion the source explicitly flags to avoid confusion. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **`LIMIT n`** — returns only the first `n` records. [S1]
+- **Purpose** — performance on large tables; avoids returning huge result sets unnecessarily. [S1]
+- **`LIMIT n OFFSET m`** — returns `n` records starting after skipping `m` records (i.e., starting at record m+1). [S1]
+- **Comma shorthand — `LIMIT m, n`** — same result as `LIMIT n OFFSET m`, but note the argument ORDER is reversed (offset first here, count first in the OFFSET form). [S1]
+
+## 📖 세부 내용 (Details)
+- First 30 records: `$sql = "SELECT * FROM Orders LIMIT 30";`. [S1]
+- Records 16-25 via OFFSET: `$sql = "SELECT * FROM Orders LIMIT 10 OFFSET 15";` — "return only 10 records, start on record 16 (OFFSET 15)". [S1]
+- Same result via comma shorthand: `$sql = "SELECT * FROM Orders LIMIT 15, 10";` — note the numbers are reversed compared to the OFFSET form. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- **콤마 문법의 숫자 순서 반전**: LIMIT n OFFSET m과 LIMIT m, n이 동일한 결과를 내지만 숫자 순서가 반대라는 점이 혼동 방지를 위해 명시적으로 강조됨. [S1]
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — 페이지네이션(16~25번째 레코드 조회)이 LIMIT+OFFSET 활용의 대표 실전 사례다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Two equivalent syntaxes for the same paginated range, with reversed argument order (SQL):
+```sql
+SELECT * FROM Orders LIMIT 10 OFFSET 15;  -- 10 records starting at record 16
+SELECT * FROM Orders LIMIT 15, 10;        -- same result, numbers reversed
+```

+## ✅ 검증 상태 및 신뢰도
+- **상태:** draft
+- **검증 단계:** conceptual
+- **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body)
+- **신뢰 점수:** 0.88
+- **중복 검사 결과:** 신규 생성 (New discovery)
+
+## 🔗 지식 그래프 (Knowledge Graph)
+- **상위/루트:** [[PHP Tutorial]]
+- **관련 개념:** [[PHP MySQL Update]], [[PHP XML Parsers]]
+- **참조 맥락:** MySQL 섹션의 마지막 — XML 파싱 섹션으로 이어짐.
