Question

conf属性值：

flyway.defaultSchema= discussions
flyway.schemas= discussions

迁移如下：

+-----------+---------+------------------------------+--------+---------------------+---------+
| Category  | Version | Description                  | Type   | Installed On        | State   |

| Versioned | 2       | R INITIAL SETUP              | SQL    |                     | Pending |
| Versioned | 3       | R1 INITIAL SETUP             | SQL    |                     | Pending |
| Versioned | 4       | CREATE TABLE TEMPLATE        | SQL    |                     | Pending |

初始设置将创建表空间

create tablespace tablespace_dts location 'E:\Tablespace\tablespace_dts';

    create tablespace tablespace_mtd location 'E:\Tablespace\tablespace_mtd';

    create tablespace tablespace_ind location 'E:\Tablespace\tablespace_ind';

    create tablespace tablespace_out location 'E:\Tablespace\tablespace_out';

    create tablespace tablespace_temp location 'E:\Tablespace\tablespace_temp';

v2将遵循

begin

for c  in select 1 where not exists (select 1 from pg_user where  usename = 'app_user' ) loop
    raise notice 'in app_user';
    execute ' create user app_user with password ''adept''';

end loop;       

for c  in select 1 where exists (select 1 from pg_tablespace,pg_user where  spcname = 'tablespace_dts' and usename = 'app_user') loop
    raise notice 'in grant create on tablespace_dts to app_user';
    execute 'grant create on tablespace tablespace_dts to app_user with grant option';

end loop;   

for c  in select 1 where exists (select 1 from pg_tablespace,pg_user where  spcname = 'tablespace_mtd' and usename = 'app_user') loop
    raise notice 'in grant create on tablespace_mtd to app_user';
    execute 'grant create on tablespace tablespace_mtd to app_user with grant option';

end loop;

for c  in select 1 where exists (select 1 from pg_tablespace,pg_user where  spcname = 'tablespace_ind' and usename = 'app_user') loop
    raise notice 'in grant create on tablespace_ind to app_user';
    execute 'grant create on tablespace tablespace_ind to app_user with grant option';

end loop;


for c  in select 1 where exists (select 1 from pg_tablespace,pg_user where  spcname = 'tablespace_out' and usename = 'app_user') loop
    raise notice 'in grant create on tablespace_out to app_user';
    execute 'grant create on tablespace tablespace_out to app_user with grant option';

end loop;


for c  in select 1 where exists (select 1 from pg_tablespace,pg_user where  spcname = 'tablespace_temp' and usename = 'app_user') loop
    raise notice 'in grant create on tablespace_temp to app_user';
    execute 'grant create on tablespace tablespace_temp to app_user with grant option';

end loop;

请注意，此处授予作品

v3将执行以下操作：


grant usage on schema discussions to app_user;

grant select on all tables in schema discussions to app_user;   

grant update on all tables in schema discussions to app_user;

grant insert on all tables in schema discussions to app_user;

grant create on schema discussions to app_user with grant option;

v4创建表，例如说webhook_certificate

因此，当我尝试在架构讨论中从app_user查询表webhook_certificate时。它说，尽管我在v3中授予了权限，但权限被拒绝。

如果手动执行相同的v3，则该v3可以运行并允许访问Discussions.webhook_certificate。请注意：v3被标记为成功，在迁移过程中没有失败。那么赠款怎么不起作用。

请帮助。

Answer 1

我知道了。感谢您的支持。

作为创建表的V4应该在V3（授权脚本）之前执行。

在现有对象上提供授权。因此，在每次迁移时，我都需要在最后运行授权脚本。为此，我可以使用afterMigrate-成功迁移后运行。

通过SQL迁移进行的Flyway拨款-不起作用
