@jinfengni Agree. It will be better to merge this patch after rebasing to
the last version of calcite. Because currently I'm not sure how to decide this
task in differ manner than mine. Do we put this PR on hold?
> Allow full schema identifier in SELECT clause
> ---------------------------------------------
>
> Key: DRILL-4682
> URL: https://issues.apache.org/jira/browse/DRILL-4682
> Project: Apache Drill
> Issue Type: Improvement
> Components: SQL Parser
> Reporter: Andries Engelbrecht
> Assignee: Vitalii Diravka
>
> Currently Drill requires aliases to identify columns in the SELECT clause
> when working with multiple tables/workspaces.
> Many BI/Analytical and other tools by default will use the full schema
> identifier in the select clause when generating SQL statements for execution
> for generic JDBC or ODBC sources. Not supporting this feature causes issues
> and a slower adoption of utilizing Drill as an execution engine within the
> larger Analytical SQL community.
> Propose to support
> SELECT <storage_plugin>.<workspace>.<table>.<column> FROM
> <storage_plugin>.<workspace>.<table>
> Also see DRILL-3510 for double quote support as per ANSI_QUOTES
> SELECT "<storage_plugin>"."<workspace>"."<table>"."<column>" FROM
> "<storage_plugin>"."<workspace>"."<table>"
> Which is very common generic SQL being generated by most tools when dealing
> with a generic SQL data source.
