PostgreSql 迁移错误
PostgreSql migration error
我有 aspnet 零项目并试图将它与 Postgresql 一起使用。我按照说明进行操作，当我尝试 Update-Database 时出现错误：
Failed executing DbCommand (18ms) [Parameters=[], CommandType='Text',
CommandTimeout='30']
CREATE SEQUENCE "AppSubscriptionPayments_Id_seq" START WITH 1 INCREMENT BY 1
NO MINVALUE NO MAXVALUE NO CYCLE;
ALTER TABLE "AppSubscriptionPayments" ALTER COLUMN "Id" TYPE int8;
ALTER TABLE "AppSubscriptionPayments" ALTER COLUMN "Id" SET NOT NULL;
ALTER TABLE "AppSubscriptionPayments" ALTER COLUMN "Id" SET DEFAULT
(nextval('"AppSubscriptionPayments_Id_seq"'));
ALTER SEQUENCE "AppSubscriptionPayments_Id_seq" OWNED BY
"AppSubscriptionPayments"."Id"
42P01: "AppSubscriptionPayments" object is not exists
我正在使用 Postgresql 10、Visual Studio 2017 和 ASPNET 零。
- 删除所有现有迁移并Add-Migration从头开始。
- 请确保您 add-migrations 时没有现有数据库（在连接字符串中指定）。如果您之前已经创建了数据库，则无法正确构建迁移。
