python - pymssql can connect to 'master' but can't connect to another database after - Stack Overflow

I do

pymssql.connect(server=self.host, user=self.username, password=self.password, port=self.port, database=database_name)

then

with conn.cursor() as cursor:

cursor.execute(sql, args)

cursor.fetchall()

then

self.interface.execute("SELECT DB_NAME()")

And I see 'master'

Then do connection.close()

And again the same loop but with 'products' as DB name. But when I do SELECT DB_NAME() again - I see 'master' again instead of 'products'

Why?

Also I've enabled tds debugs and I see next

So context changed but I still somehow get 'master' as context. Why?
