Question

我有sql / text文件，我想检查分隔符，如＆＃34 ;;＆＃34;，＆＃34; /＆＃34;，＆＃34; GO＆＃34;如果它们被重复或有它们的组合，那么它应该删除不需要的并且在输出文件中仅保留如下标准。

我写了下面的python程序，它做了一些工作，但某些情况下它失败了; /; /; /或/// ;;; （双重或重复终止子）。你对此的帮助非常赞赏。

import re

new_lines = re.compile('\n{2,50}')

# Read in the file
with open('file.sql', 'r') as file :
  filedata = file.read()
  filedata = re.sub(new_lines, '\r\n', filedata.strip())

# Replace the target string
for line in filedata:
   filedata = filedata.replace(';\n', '\n')
   filedata = filedata.replace('/\n', '\n')
   filedata.split('\n')
 #filedata = filedata.split('/')
 #filedata = re.sub(new_lines, '/', filedata.strip())
   filedata = re.sub(r'(/)\1+', r'\1', filedata)
   filedata = re.sub(r'(/)\1+', r'\1', filedata)

# Write the file out again
with open('fileOut.sql', 'w') as file:
  file.write(filedata)

输入文件1.sql：

--Query to select the records where BUS_TYP_STA = 1 where cert_strt_dt = ‘12/31/9999’ and cert_end_dt is not null

使用PYTHON消除sql文件中的分隔符（;，/）
