> aggregate FILTER pushing invalid SQL to vendors that do not support it.
> ------------------------------------------------------------------------
>
> Key: DRILL-5620
> URL: https://issues.apache.org/jira/browse/DRILL-5620
> Project: Apache Drill
> Issue Type: Bug
> Components: SQL Parser
> Affects Versions: 1.10.0
> Environment: Drill 1.10
> Reporter: N Campbell
>
> Calcite's parser documentation indicates that it has provided for
> aggregate(<exp>) FILTER.
> This construct is not supported by many vendors, hence it such a statement is
> expressed to Drill against a plugin mapped to JDBC it may fail due to the
> statement being push down (i.e. to ORACLE). But the operation will
> parse/execute when performed locally on dfs etc
> select count( CINT ) filter ( where RNUM > -1) from x.y.z
> DATA_READ ERROR: The JDBC storage plugin failed while trying setup the SQL
> query
