> Key: DRILL-7870
> URL: https://issues.apache.org/jira/browse/DRILL-7870

> Issue Type: Improvement
> Components: Storage - JDBC
> Reporter: Prabhakar Bhosale
> Assignee: Cong Luo
> Priority: Major
>
> Hi,
> As I understood, drill is currently not supporting the prepared statement to
> query the storage. I feel this is the required feature in the drill as drill
> now getting integrated with many ETL tools. I am trying to integrate it with
> Pentaho.
> I am using the JDBC driver from the URL
> [https://package.mapr.com/tools/MapR-JDBC/MapR_Drill/MapRDrill_jdbc_v1.6.6.1009/]
>
> If I use the prepared statement it gives error as below
> +java.sql.SQLException+: [MapR][DrillJDBCDriver](500980) Encountered error
> while creating prepared statement. Details: PLAN ERROR: Cannot convert
> RexNode to equivalent Drill expression. RexNode Class:
> org.apache.calcite.rex.RexDynamicParam, RexNode Digest: ?0
>
> I request to check the feasibility of having this feature. thanks
>
> Regards
> Prabhakar
