             Summary: CheckAnalysis for data source V2 ALTER TABLE ignores case 
sensitivity
                 Key: SPARK-29103
                 URL: https://issues.apache.org/jira/browse/SPARK-29103
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Jose Torres


For each column referenced, we run

```val field = table.schema.findNestedField(fieldName, includeCollections = 
true)```

and fail analysis if the field isn't there. This check is always case-sensitive 
on column names, even if the underlying catalog is case insensitive, so it will 
sometimes throw on ALTER operations which the catalog supports.
