`files`, `table_name` and `file_location` are template fields, so they are rendered after `__init__` runs. The constructor checked `files`/`pattern` mutual exclusivity and rejected an empty `table_name`/`file_location` there, acting on the un-rendered Jinja expressions — so a templated `table_name` couldn't resolve before the empty check ran. Move those three checks into `execute()`. The `file_format` check reads no template field and stays in `__init__`. related: #70296 <details><summary>Testing Done</summary> New `test_files_and_pattern_rejected_at_execute` constructs with both `files` and `pattern` and asserts the `AirflowException` now surfaces from `execute()`. It fails on the pre-fix source (the constructor raises first) and passes after. `test_databricks_sql.py`: 52 passed. `validate_operators_init.py` exits 0 and the `raise AirflowException` count is unchanged. </details> --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes (please specify the tool below) Generated-by: GitHub Copilot CLI following [the guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#gen-ai-assisted-contributions) -- This is an automated message from the Apache Git Service.
