postgres列“ X”不存在

Question

我有这个邮政编码：

CREATE TABLE IF NOT EXISTS config_change_log
(
  id                    serial primary key,
  last_config_version   varchar(255) NOT NULL,
  is_done               Boolean NOT NULL DEFAULT '0',
  change_description     varchar(255),
  timestamp timestamp   default current_timestamp
);

INSERT INTO config_change_log(last_config_version, is_done, change_description )
VALUES("5837-2016-08-24_09-12-22", false, "{ 'key':'value'}");

我得到这个错误：

psql:createConfigChangeLog.sql:11: ERROR:  column "5837-2016-08-24_09-12-22" does not exist
LINE 2: VALUES("5837-2016-08-24_09-12-22", false, "{ 'key':'value'}"...

怎么会这样？这是一个值而不是column.postgr

Answer 1

使用single quotes的字符串常量

INSERT INTO config_change_log(last_config_version, is_done, change_description )
VALUES('5837-2016-08-24_09-12-22', false, '{ ''key'':''value''}');

您也可以single quotes通过将它们加倍来逃脱数据
