# You can use this function
 def getColumns(cursorDescription):

     return columnList 

摘自Mark Lutz的《Programming Python》:

curs.execute("Select * FROM people LIMIT 0")
colnames = [desc[0] for desc in curs.description]

你可以做的另一件事是创建一个游标，你可以通过它们的名字引用你的列(这是一个需要，导致我在第一个地方到这个页面):

import psycopg2
from psycopg2.extras import RealDictCursor

ps_conn = psycopg2.connect(...)
ps_cursor = psql_conn.cursor(cursor_factory=RealDictCursor)

ps_cursor.execute('select 1 as col_a, 2 as col_b')
my_record = ps_cursor.fetchone()
print (my_record['col_a'],my_record['col_b'])

>> 1, 2

 # You can use this function
 def getColumns(cursorDescription):
     columnList = []
     for tupla in cursorDescription:
         columnList.append(tupla[0])
     return columnList 

我注意到你必须在查询后使用cursor.fetchone()来获取cursor.description中的列列表(即在[desc[0] for desc in curs.description])

执行SQL查询后，编写2.7中编写的python脚本

total_fields = len(cursor.description)    
fields_names = [i[0] for i in cursor.description   
    Print fields_names
