Doctrine 2 Symfony 5 migration to an oracle database - oracle

Question

I have
PHP 8.0
Ubuntu 20.4 running in a VM
Symfony Version 5
doctrine/orm 2.8.2
doctrine/dbal 2.12.1
doctrine/migrations 3.1.1
and oracle19c running
I have also some entities which I want now to make:migrate with doctrine. But at this point I stuck on this error:
More information:
In doctrine.yaml:
dbal:
default_connection: oracle
connections:
default:
schema_filter: ~^(?!t_cmdb_|m_cmdb_|migration_versions)~
mapping_types:
enum: string
# configure these for your database server
url: '%env(resolve:DATABASE_URL)%'
driver: 'pdo_mysql'
server_version: '5.7'
charset: utf8mb4
oracle:
schema_filter: ~^(?!t_cmdb_|m_cmdb_|migration_versions)~
mapping_types:
enum: string
# configure these for your database server
url: '%env(resolve:DATABASE_CUSTOMER_URL)%'
servicename: 'pdb'
service: true
driver: 'oci8'
server_version: ~
charset: AL32UTF8
I have a oracle database created with:
php bin/console doctrine:database:create --connection oracle
which goes through without any problems
Than I call
php bin/console make:migration -vvv
I got this error message:
[Doctrine\DBAL\Exception]
Unknown database type interval day(3) to second(2) requested, Doctrine\DBAL\Platforms\OraclePlatform may not support it.
All my date columns have the type datetime there is no interval in there!
I have searched for this problem but I can't come through.
Did somebody has this Problem while making migration for doctrine?
Thanks a lot for any hint.

Doctrine commands usually scan all tables in the user/schema defined in Symfony's .env file (look for DATABASE_USER). That error means that at least one of the tables in that schema has a column of type "INTERVAL...".
If you are sure that you don't have any table with an "INTERVAL..." type column, it may be that you are using directly the SYSTEM user/schema (or any other Oracle reserved user/schema). In this case, you need to create a separate user/schema for your project and move your project tables there.
Anyway, run this to check which tables under which user/schema (OWNER) have a column of type "INTERVAL...":
SELECT
OWNER,
TABLE_NAME ,
COLUMN_NAME,
DATA_TYPE,
DATA_LENGTH,
DATA_PRECISION,
DATA_SCALE
FROM ALL_TAB_COLUMNS
where
data_type like 'INTERVAL%'
-- and OWNER = 'YOUR_USER_SCHEMA' -- must be in uppercase
ORDER BY TABLE_NAME
If you do use such a column type in your project, then you must add that column type in Doctrine's configuration: https://www.doctrine-project.org/projects/doctrine-orm/en/latest/cookbook/custom-mapping-types.html
If you discover that you were using the SYSTEM user/schema directly (perhaps in a Docker container?), then create your separate project user/schema:
CREATE USER your_separate_user_schema IDENTIFIED BY oracle; -- oracle is the password
Grant create session to your_separate_user_schema ; -- to be able to login with the new user
ALTER USER your_separate_user_schema quota unlimited on USERS; -- give your user schema disk space
To copy only the necessary tables from SYSTEM to your_separate_user_schema: while in system/sysdba, for each table do:
create table your_separate_user_schema.table_name as select * from table_name ;
