Allison Wang updated SPARK-37716:
---------------------------------
Description:
After https://issues.apache.org/jira/browse/SPARK-37199, Analyzer will block
LateralJoin that has non-deterministic lateral subqueries. But when the outer
query is a single row relation, this should be allowed
For example:
Query:
{code:java}
SELECT * FROM VALUES(0) t(x) JOIN LATERAL (SELECT rand(0) + x AS y); {code}
Result:
{code:java}
org.apache.spark.sql.AnalysisException: nondeterministic expressions are only
allowed in
Project, Filter, Aggregate or Window{code}
