python peewee原始查询，不转义字符

Question

Is there any way to prevent escaping backslash in python peewee (peewee-2.8.8) ORM?

I would like to execute query in MySQL database:

SHOW MASTER STATUS\G

The "\\G" part is essential! I need to the results in vertical form.

The problem is that peewee always escapes backslash (\\) so it ends in MySQL as:

SHOW MASTER STATUS\\G

and of course MySQL issues an error:

 "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '\\G' at line 1"

I tried to use plain "execute_sql" method:

cursor = RaDatabase.execute_sql('SHOW MASTER STATUS\G')

and also "raw" method:

query = BaseModel.raw('SHOW MASTER STATUS\G')
result = query.execute()

but both ended with escaping characters.

Answer 1

Have you tried using a "raw" string?

cursor = RaDatabase.execute_sql(r'SHOW MASTER STATUS\G')

For what it's worth, whatever you pass in to .execute_sql() is essentially handed over to the MySQL driver (pymysql, or whatever you're using). Peewee itself does not do any escaping.
