sql - 在 SQL 上向表中插入信息

Question

我正在尝试将新信息插入到已经存在的表中。这是我的代码不起作用：

INSERT INTO customer (cNo, cName, street, city, county, discount)
VALUES (10, Tom, Long Street, Short city, Wide County, 2);

我哪里错了？

Answer 1

您必须对字符串值使用引号：

INSERT INTO customer (cNo, cName, street, city, county, discount)
VALUES (10, 'Tom', 'Long Street', 'Short city', 'Wide County', 2);

Answer 2

您没有正确指定您的字符串，它应该是：

INSERT INTO customer (cNo, cName, street, city, county, discount) 
VALUES (10, 'Tom', 'Long Street', 'Short city', 'Wide County', 2);

Answer 3

您必须用逗号分隔值，并用引号 (' ') 将文本字段括起来。检查这个

试试这个代码：

INSERT INTO customer (cNo, cName, street, city, county, discount) 
VALUES (10, 'Tom', 'Long Street', 'Short city', 'Wide County', 2);
