SQL INSERT INTO 关键字

❮ 上一个 ❮ SQL 关键字 参考 下一个 ❯

INSERT INTO

INSERT INTO 命令用于在表中插入新行。

以下 SQL 语句在 "Customers" 表中插入一个新记录。

示例

INSERT INTO Customers (CustomerName, ContactName, Address, City, PostalCode, Country)
VALUES ('Cardinal', 'Tom B. Erichsen', 'Skagen 21', 'Stavanger', '4006', 'Norway');

以下 SQL 语句将插入一个新记录，但仅在 "CustomerName"、"City" 和 "Country" 列中插入数据（CustomerID 将自动更新）

示例

INSERT INTO Customers (CustomerName, City, Country)
VALUES ('Cardinal', 'Stavanger', 'Norway');
