(JDBC) support nest select with current version
@Hao,
Because the querying joined more than one table, if I register data frame as
temp table, Spark can't disguise which table is correct. I don't how to set
dbtable and register temp table.
Any suggestion?

You need to register the “dataFrame” as a table first and then do queries on
it? Do you mean that also failed?

If I pass the whole statement as dbtable to sqlContext.load() method as
below:val query =
"""
(select t1._salory as salory,
|t1._name as employeeName,
|(select _name from mock_locations t3 where t3._id = t1._location_id ) as
locationName
|from mock_employees t1
|inner join m
