在分隔符';'之間提取sql語句使用python RE

Question

我有如下語句的SQL文件，聲明需要提取

select * from customers; 

select count(*) from customers; 

select a.cust_name,sum(b.revenue) from 
customers a join revenue_tab b 
on a.c_id=b.c_id 
group by a.cust_name; 

下面

是Python代碼中提取SQL語句和計數一次選擇關鍵字的數量出現在聲明中

import re 

query = {} 

def GetTheStatements(): 
    with open('dummy.sql') as fp: 
     for result in re.findall('(.*?);', fp.read(), re.S): 
      count_select = sum(1 for x in re.finditer(r"\bselect\b", result)) 
      q = {result :{ 'count_select': count_select}} 
      query.update(q) 
    print query 

GetTheStatements() 

但是得到的字典將看起來像這樣

{'\n\nselect count(*) from customers': {'count_select': 1}, '\nselect * from customers': {'count_select': 1}, ' \n\nselect a.cust_name,sum(b.revenue) from\ncustomers a join revenue_tab b \non a.c_id=b.c_id\ngroup by a.cust_name': {'count_select': 1}} 

如何剝去換行符（\ n）還有時（\ r）從它獲取正則表達式中的語句？

Answer 1

如果你有，

q = {result :{ 'count_select': count_select}} 

你可以代替，

q = {re.sub(r'[\n\r]', '', result) :{ 'count_select': count_select}}
