Summary: [M0] Support for local variables
Key: SPARK-48530
URL: https://issues.apache.org/jira/browse/SPARK-48530
Project: Spark
Issue Type: Sub-task
Components: Spark Core
Affects Versions: 4.0.0
Reporter: David Milicevic
At the moment, variables in SQL scripts are creating session variables. We
don't want this, we want variables to be considered as local (within the
block/compound).
To achieve this, we probably need to wait for labels support. Once we have it,
we can prepend variable names with labels to make distinction between variables
with the same name and only then reuse session variables mechanism to save
values with such composed names.
If the block/compound doesn't have label, we should generate it automatically
(GUID or something similar).
