# [[SQL Insert Into]]

## 🎯 한 줄 통찰 (One-line insight)
INSERT INTO adds new records to a table, either by specifying columns and matching values explicitly or by supplying values for every column in table order, and it supports inserting multiple rows in one statement. [S1]

## 🧠 핵심 개념 (Core concepts)
- **INSERT INTO statement** — inserts new records into a table. [S1]
- **Syntax 1 (explicit columns)** — `INSERT INTO table_name (column1, column2, column3, ...) VALUES (value1, value2, value3, ...);`. [S1]
- **Syntax 2 (all columns, no names)** — `INSERT INTO table_name VALUES (value1, value2, value3, ...);`, valid only if values are supplied for every column in the exact column order. [S1]
- **Partial-column insert** — specific columns can be targeted (e.g. `CustomerName, City, Country`); unspecified columns are left `null` (or auto-generated for identity columns). [S1]
- **Multi-row insert** — a single INSERT INTO statement can insert several rows by comma-separating multiple `VALUES(...)` groups. [S1]

## 🧩 추출된 패턴 (Extracted patterns)
- **Auto-increment omission** — when a column is an auto-increment primary key (e.g. `CustomerID`), it must NOT be given a value; the database generates it automatically. [S1]
- **Column-order dependency** — Syntax 2's positional values must exactly match the table's column definition order, making it fragile to schema changes compared to Syntax 1. [S1]

## ⚖️ 비교 및 선택 기준 (Comparison & decision criteria)

| 항목 (Option) | 장점 | 단점 | 언제 선택 |
|---|---|---|---|
| **Syntax 1 (컬럼명 명시)** | 컬럼 순서에 안전하고 의도가 명확함, 일부 컬럼만 삽입 가능 | 타이핑이 더 김 | 프로덕션 코드, 일부 컬럼만 채울 때 |
| **Syntax 2 (컬럼명 생략)** | 간결함 | 테이블 스키마가 바뀌면 깨지기 쉬움, 전체 컬럼 값이 반드시 필요 | 빠른 테스트/스크립트, 스키마가 고정적일 때 |

## 📖 세부 내용 (Details)
- Insert a full new record by omitting column names (values must follow table column order): [S1]
```sql
INSERT INTO Customers
VALUES ('Cardinal', 'Tom B. Erichsen', 'Skagen 21', 'Stavanger', '4006', 'Norway');
```
  Note: `CustomerID`는 auto-increment 필드이므로 값을 지정하지 않아도 자동 생성된다. [S1]
- Insert data only in specific columns (others become `null`): [S1]
```sql
INSERT INTO Customers (CustomerName, City, Country)
VALUES ('Cardinal', 'Stavanger', 'Norway');
```
- Insert multiple rows in one statement by comma-separating value groups: [S1]
```sql
INSERT INTO Customers (CustomerName, ContactName, Address, City, PostalCode, Country)
VALUES
('Cardinal', 'Tom B. Erichsen', 'Skagen 21', 'Stavanger', '4006', 'Norway'),
('Greasy Burger', 'Per Olsen', 'Gateveien 15', 'Sandnes', '4306', 'Norway'),
('Tasty Tee', 'Finn Egan', 'Streetroad 19B', 'Liverpool', 'L1 0AA', 'UK');
```
  Note: 각 값 그룹은 쉼표(,)로 구분해야 한다. [S1]

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

## 🛠️ 적용 사례 (Applied in summary)
현재 발견된 실제 적용 사례가 없습니다 — INSERT INTO는 이후 SQL Insert Into Select(다른 테이블의 조회 결과를 삽입) 챕터의 선행 개념이다. [S1]

## 💻 코드 패턴 (Code patterns)
Insert full record, columns implied by table order (SQL):
```sql
INSERT INTO Customers
VALUES ('Cardinal', 'Tom B. Erichsen', 'Skagen 21', 'Stavanger', '4006', 'Norway');
```
Insert multiple rows in one statement (SQL):
```sql
INSERT INTO Customers (CustomerName, ContactName, Address, City, PostalCode, Country)
VALUES
('Cardinal', 'Tom B. Erichsen', 'Skagen 21', 'Stavanger', '4006', 'Norway'),
('Greasy Burger', 'Per Olsen', 'Gateveien 15', 'Sandnes', '4306', 'Norway');
```
