SamWheating opened a new issue #19988:
URL: https://github.com/apache/airflow/issues/19988
### Apache Airflow version
2.2.2 (latest released)
### Operating System
Debian GNU/Linux 10 (buster)
### Versions of Apache Airflow Providers
_No response_
### Deployment
Other 3rd-party Helm chart
### Deployment details
Using MySQL 8.0 via Google CloudSQL
### What happened
When upgrading from 2.1.2 to 2.2.2 the `airflow db upgrade` command failed
with the following command:
```
sqlalchemy.exc.OperationalError: (MySQLdb._exceptions.OperationalError)
(1786, 'Statement violates GTID consistency: CREATE TABLE ... SELECT.')
[SQL: create table _airflow_moved__2_2__task_instance as select source.*
from task_instance as source
left join dag_run as dr
on (source.dag_id = dr.dag_id and source.execution_date =
dr.execution_date)
where dr.id is null
]
```
On further investigation, it looks like `CREATE TABLE AS SELECT ...` queries
will cause GTID consistency violations whenever mySQL GTID-based replication is
used
([source](https://dev.mysql.com/doc/refman/5.7/en/replication-gtids-restrictions.html)).
This is used by default on all Google CloudSQL mySQL instances, so they will
always block these queries
([source](https://cloud.google.com/sql/docs/mysql/features#unsupported-statements))
It looks like these queries are created here:
https://github.com/apache/airflow/blob/eaa8ac72fc901de163b912a94dbe675045d2a009/airflow/utils/db.py#L739-L747
Could we refactor this into two separate queries like:
```python
else:
# Postgres, MySQL and SQLite all have the same CREATE TABLE a AS SELECT
... syntax
session.execute(
text(
f"create table {target_table_name}"
)
)
session.execute(
text(
f"INSERT INTO {target_table_name} select source.* from
{source_table} as source " + where_clause
)
)
```
In order to preserve the GTID consistency?
