------------------------------------
Assignee: Apache Spark
> JDBC AND operator push down
> ----------------------------
>
> Key: SPARK-12409
> URL: https://issues.apache.org/jira/browse/SPARK-12409
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: Huaxin Gao
> Assignee: Apache Spark
> Priority: Minor
>
> For simple AND such as
> select * from test where THEID = 1 AND NAME = 'fred',
> The filters pushed down to JDBC layers are EqualTo(THEID,1),
> EqualTo(Name,fred). These are handled OK by the current code.
> For query such as
> SELECT * FROM foobar WHERE THEID = 1 OR NAME = 'mary' AND THEID = 2" ,
> the filter is Or(EqualTo(THEID,1),And(EqualTo(NAME,mary),EqualTo(THEID,2)))
> So need to add And filter in JDBC layer.
