Python - 파일에서 다중 SQL 쿼리 실행

Question

파이썬 2.7.13의 파일에서 SQL 쿼리를 실행하고 결과 집합을 표시하는 동안 다음 오류가 발생합니다. 파일의 SQL 문은 테이블의 count (*)처럼 단순하지만이 논리가 작동하면 복잡한 쿼리로 바꿔야합니다.

오류

Info : (7,) 
Traceback (most recent call last): 
    File "SQLserver_loop.py", line 19, in <module> 
    fields = c.fetchall() 
    File "pymssql.pyx", line 542, in pymssql.Cursor.fetchall (pymssql.c:9352) 
pymssql.OperationalError: Statement not executed or executed statement has no re 
sultset 

파이썬 스크립트 :

import pymssql 

conn = pymssql.connect(
    host=r'name', 
    user=r'user', 
    password='credential', 
    database='Test') 

c = conn.cursor() 


fd = open('ZooDatabase.sql', 'r')  # Open and read the file as a single buffer 

sqlFile = fd.read() 

fd.close() 


sqlCommands = sqlFile.split(';')  # all SQL commands (split on ';') 


for command in sqlCommands:   # Execute every command from the input file 

    c.execute(command) 

    fields = c.fetchall() 

    for row in fields: 

     print "Info : %s " % str(row) 

c.close() 

conn.close()

Answer 1

fields = c.fetchall() 내가 오류를 일으켰고 나는 그것을 주석 처리했으며 현재 잘 작동한다.

for command in sqlCommands: 

    #print command 
    c.execute(command) 
    #fields = c.fetchall() 
    for row in c: 
     print (row)
