----------------------------------

             Summary: 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
            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.
