mysql - 将时间戳从 MySQL 导入到 Postgres

Question

我使用 mysqldump 和 psql 从 MySQL 迁移到 Postgres 并收到此错误:

ERROR: date/time field value out of range: "0000-00-00 00:00:00" at character 52 STATEMENT: INSERT INTO "cron" VALUES (1,'2015-07-11 05:21:40','0000-00-00 00:00:00',2,58,'updateBid','plus',NULL,NULL),(2,'2015-07-11 05:21:40','0000-00-00

MySQL 表看起来像

CREATE TABLE "cron" (
  "id" int(11) NOT NULL,
  "execute_after" timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  "executed_at" timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',

Postgres 表如下所示:

CREATE TABLE "cron" (
  "id" int NOT NULL,
  "execute_after" timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  "executed_at" timestamp,

如何自动导入该字段？

Answer 1

好的，我用 sed 解决了这个问题:

mysqldump --compress --compatible postgresql --no-create-info --compact dbname | sed $'s/\'0000-00-00 00:00:00\'/NULL/g' | psql dbname
