[jira] [Created] (DRILL-5620) aggregate FILTER is being pushed to
vendors that do not support it.
N Campbell created DRILL-5620:
---------------------------------
Summary: aggregate FILTER is being pushed 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. 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
