SQLAlchemy insert special characters operations
Quotes error
You have encountered an error when inserting a string of quotes when using SQLAlchemy execute sql statements
such as the following code in sql after splicing into a string of comments, this time, of course insert mysql error.
content = 'test"hhhh",'
sql = 'insert into comment(content) values("%s")'%content
#insert into comment(content) values("test"hhhh",")
execute_sql(sql)
Solution:
1. escaped as their own quotes with a backslash
content = content.replace('"','\\"')2. Third-party dependencies
import pymysql
content =pymysql.escape_string(content ) pymysql.escape_string can escape character
Colon error
Recent problems encountered in a giant pit string begins with a colon also can not be saved, or in the presence of a string of Chinese punctuation colon can not be saved. (Specific reasons not found, this operation seems to be treated as an object in the SQLAlchemy)
content = ":test"
content = "，:test"
sql = 'insert into comment(content) values("%s")'%content
execute_sql(sql)
