我试图从数据库中提取记录,对其中一个字段进行一些处理,然后将数据插回到数据库中。但是,我注意到脚本在一次插入成功后停止,即使插入到数据库中的记录数量多于其他记录。MySQL从Python插入停止
cur = db.cursor()
# Pull records from the database, process each one, and store back into the database
SQLQuery = """SELECT * FROM cybersecurity4.hackhoundposts"""
cur.execute(SQLQuery)
for row in cur:
postID = row[0]
threadID = row[1]
authorID = row[2]
url = row[3]
subforum = row[4]
threadTitle = row[5]
authorName = row[6]
postDateTime = row[7]
postSequence = row[8]
flatcontent = row[9]
userTitle = row[11]
hasAttachment = row[12]
print (postID)
# #process the flatcontent
flatcontent = rmvSpecialCharsandCamelCase(flatcontent)
# insert into the database
try:
string = """INSERT INTO cybersecurity4.cleanedhackhoundposts
(postid, threadid, authorid, URL, subforum, threadTitle, authorName, postdatetime, postSequence, flatcontent, usertitle, hasattachment)
VALUES ('%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s','%s', '%s', '%s', '%s');""" % \
(postID ,threadID,authorID,url,subforum,threadTitle,authorName,postDateTime,postSequence,flatcontent,userTitle,hasAttachment)
print (string)
cur.execute(string)
print ("Successfully inserted post " + str(postID))
except:
int("Failed to insert post" + str(postID))
这是一个非常糟糕的做法,只是'除了'。尝试将其更改为可能在此处发生的特定异常。 – grael
