gfee-home opened a new issue, #16648:
URL: https://github.com/apache/datafusion/issues/16648
### Describe the bug
If you create a table with a struct column where a field in the struct
include a capital letter then the query planner will complain that it cannot
find that field.
### To Reproduce
1. Create a JSON file named "test.json" with content:
{"thing": {"fooBar": "not going to find me"}}
2. Start the Datafusion cli
3. Execute "select thing.fooBar from 'test.json';"
Actual: The query will fail saying 'Error during planning: Field foobar not
found in struct'.
Expected: The query executes returning 1 row with content "not going to find
me"
Note: if you change the content of the file to:
{"thing": {"foobar": "not going to find me"}}
where the only change is "fooBar" to "foobar" then everything works.
### Expected behavior
Expected: The query executes returning 1 row with content "not going to find
me"
Note: if you change the content of the file to:
{"thing": {"foobar": "not going to find me"}}
where the only change is "fooBar" to "foobar" then everything works.
