SQLAlchemy: How to change a MySQL server system variable using SQLAlchemy?
Question:
I want to set the general_log and general_log_file variables using SQLAlchemy, is there a way to do this? I’ve been Googling around and can’t find anything on the topic.
Answers:
You can execute any raw SQL query which you need (of course you have to get appropriate rights in the session). To change a variable run something like this:
# change variable name and values to what you need
connection.execute("SET SESSION query_cache_type = OFF")
As mentioned previously, you could use the following code the set a variable using the raw Connection object.
connection.execute("SET SESSION query_cache_type = OFF")
If you have a Session object, you can retrieve the underlying Connection object using the Session.connection() function.
So your code could look as follows.
session.connection().execute("SET SESSION query_cache_type = OFF")
