Question

我有这个postgrse代码：

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'}");

我收到此错误：

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？它的值不是column.postgr

Answer 1

将single quotes用于字符串常量

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

此外，您可以通过将数据加倍来逃避single quotes数据
