---------------------------------
Summary: Allow specifying session catalog name (spark_catalog) in
qualified column names
Key: SPARK-31024
URL: https://issues.apache.org/jira/browse/SPARK-31024
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.0.0, 3.1.0
Reporter: Terry Kim
Currently, the user cannot specify the session catalog name when using
qualified column names for v1 tables:
{code:java}
SELECT spark_catalog.default.t.i FROM spark_catalog.default.t
{code}
fails with "cannot resolve '`spark_catalog.default.t.i`".
This is inconsistent with v2 tables where catalog name can be used:
{code:java}
SELECT testcat.ns1.tbl.id FROM testcat.ns1.tbl.id
{code}
