             Summary: Cannot resolve attribute with table reference
                 Key: SPARK-36768
                 URL: https://issues.apache.org/jira/browse/SPARK-36768
             Project: Spark
          Issue Type: Task
          Components: SQL
    Affects Versions: 3.1.2, 3.0.3, 2.4.7
            Reporter: Willi Raschkowski


Spark seems in some cases unable to resolve attributes that contain multi-part 
names where the first parts reference a table. Here's a repro:
{code:python}
>>> spark.range(3).toDF("col").write.parquet("testdata")

# Single name part attribute is fine
>>> spark.sql("SELECT col FROM parquet.testdata").show()
+---+
|col|
+---+
|  1|
|  0|
|  2|
+---+

# Name part with the table reference fails
>>> spark.sql("SELECT parquet.testdata.col FROM parquet.testdata").show()

AnalysisException: cannot resolve '`parquet.testdata.col`' given input columns: 
[col]; line 1 pos 7;
'Project ['parquet.testdata.col]
+- Relation[col#50L] parquet
{code}

This also reproduces on master at time of writing.
