MySQL 创建和插入数据时收到语法错误

Question

我创建一个table

create table if not exists gbpExchangeRates (
    date date
    , to_currency char(3)
    , rate float
    , index idx (date, to_currency)
);

然后添加然后尝试插入数据

INSERT INTO gbpExchangeRates ('date', 'to_currency', 'rate') VALUES ('2018-01-22', 'CAD', 1.7253437447) ;

但是我得到以下错误

SQL Error [1064] [42000]: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''date', 'to_currency', 'rate') VALUES ('2018-01-22', 'CAD', 1.7253437447)' at line 1

我尝试了以下方法但仍然收到错误消息：

ALTER TABLE gbpExchangeRates MODIFY to_currency char(10);
ALTER TABLE gbpExchangeRates MODIFY to_currency varchar(10);
ALTER TABLE gbpExchangeRates MODIFY rate double;
ALTER TABLE gbpExchangeRates MODIFY to_currency varchar(10);
INSERT INTO gbpExchangeRates ('date', 'to_currency', 'rate') VALUES ('2018-01-22', 'CAD', 1.72) ;
和

我的 table and/or 插入语句有什么问题？

Answer 1

INSERT INTO gbpExchangeRates (date, to_currency, rate) VALUES ('2018-01-22', 'CAD', 1.7253437447) ;

要插入的字段不需要引号

Answer 2

字段名称不带引号，或者您可以使用反引号

Answer 3

去掉单引号

INSERT INTO gbpExchangeRates (date, to_currency, rate) VALUES
('2018-01-22', 'CAD', 1.7253437447) ;
