Patrick McFadin commented on CASSANDRA-20224:
---------------------------------------------
Patched and created PR: [https://github.com/apache/cassandra/pull/3810]
This patch uses the same syntax as the non-LET statement SELECT. It should be
pretty straightforward. Syntax was tested on CEP-15 branch and worked as
expected.
> Add alias (AS) support to Accord LET SELECT statement

> Key: CASSANDRA-20224
> URL: https://issues.apache.org/jira/browse/CASSANDRA-20224
> Project: Apache Cassandra
> Issue Type: Improvement
> Components: Accord
> Reporter: Patrick McFadin
> Assignee: Patrick McFadin
> Priority: Normal
>
> When creating tuples inside an Accord transaction block, the LET statement
> currently does not allow for aliases( AS ) in the column select. Example not
> allowed:
> LET tuple_data = (SELECT col1 AS firstName, col2 AS lastName FROM ks.t);
> It's a simple patch in the Parser.g to fix that.
