默认情况下,cx_oracle将每一行作为元组返回。

>>> import cx_Oracle
>>> conn=cx_Oracle.connect('scott/tiger')
>>> curs=conn.cursor()
>>> curs.execute("select * from foo");
>>> curs.fetchone()
(33, 'blue')

如何将每一行作为字典返回?

最佳答案

您可以覆盖光标的rowfactory方法。每次执行查询时都需要这样做。
这是标准查询的结果,一个元组。

curs.execute('select * from foo')
curs.fetchone()
    (33, 'blue')

返回命名元组:
def makeNamedTupleFactory(cursor):
    columnNames = [d[0].lower() for d in cursor.description]
    import collections
    Row = collections.namedtuple('Row', columnNames)
    return Row

curs.rowfactory = makeNamedTupleFactory(curs)
curs.fetchone()
    Row(x=33, y='blue')

返回词典:
def makeDictFactory(cursor):
    columnNames = [d[0] for d in cursor.description]
    def createRow(*args):
        return dict(zip(columnNames, args))
    return createRow

curs.rowfactory = makeDictFactory(curs)
curs.fetchone()
    {'Y': 'brown', 'X': 1}
