Ian Hellstrom updated DRILL-4506:
---------------------------------
Affects Version/s: 1.5.0
> Allow substitution variables in SQL scripts
> -------------------------------------------
>
> Key: DRILL-4506
> URL: https://issues.apache.org/jira/browse/DRILL-4506
> Project: Apache Drill
> Issue Type: Wish
> Components: SQL Parser
> Affects Versions: 1.5.0
> Reporter: Ian Hellstrom
> Labels: features
>
> It would be great if substitution variables could be created à la SQL*Plus in
> scripts. This would be especially helpful when objects need to be
> (re-)created from scratch (i.e. in testing), and they share e.g. workspaces,
> which have to be hard-coded otherwise.
> The following is a rough idea (based on SQL*Plus syntax):
> {code}
> IN_LOCATION=hdfs.project
> OUT_LOCATION=hdfs.storage
> CREATE VIEW &OUT_LOCATION.view_name AS
> SELECT * FROM &IN_LOCATION.table_name;
> {code}
> For a first implementation, it would be best to have simply substitution
> variables and not allow computations to be done, although it is conceivable
> that that would be a second step.
