Subject: [storm] Query result in dict object.
Message-ID: <etPan.5aefeac6.5525af7e.2c5e@igarment.net>


I can run sql select statment using store.execute()  And I get a ResultSet.  How can I get a dictionary object instead of a tuple list?

I know I can get the column names from the result set cursor description.  Then map the cursor column name with the tuple, is there a build in method which do this already?

I can

result = store.execute(‘Select * from a_table’)
fields = [ f[0] for f in result._raw_cursor.description ]
for data in result:
   record = dict(zip(fields, data))

By the way, is there any document on how to use Expr?
