问题 I'd like to use the mysql-connector library for python 3. I could use pymysql instead, but mysql-connector already has a connection pool implementation, while pymysql doesn't seem to have one. So this would be less code for me to write. However, when I do $ pip3 search mysql-connector I find that these 3 libraries are available: mysql-connector-repackaged - MySQL driver written in Python mysql-connector-python-rf - MySQL driver written in Python mysql-connector-python - MySQL driver written

MySQL/Python — committed changes not appearing in loop

一世执手 提交于 2019-12-02 20:04:33
问题 Using MySQL Connector/Python I have a loop that keeps checking a value for a change every 2 seconds. Without all the meat, here is the loop (the print is there for testing purposes: try: while True: request = database.get_row(table="states", wherecol="state", whereval="request_from_interface")[0] print(request.value) time.sleep(2) except KeyboardInterrupt: pass # back to normal operation get_row is a simple select query and it returns the namedtuple fetchall (hence the [0] at the end, it will

The data structure is set as follows(if anything is better to be changed please kindly let me know): +-------

问题 I'm working with pandas and sqlalchemy, and would like to load a DataFrame into a MySQL database. I'm currently using this code snippet: db_connection = sqlalchemy.create_engine('mysql+mysqlconnector://user:pwd@hostname/db_name') some_data_ref.to_sql(con=db_connection, name='db_table_name', if_exists='replace') sqlalchemy , pandas have been imported prior to this. My MySQL backend is 8.x, which I know uses caching_sha2_password . If I were to connect to the database using mysql.connector

Unable to find Protobuf include directory during install mysql-connector over pip

I pulled mysql-connector-python code and when I run python ./setup.py build I get the following error: Unable to find Protobuf include directory. pip install Protobuf was useless How can I solve this problem? yutaka2487 I found that this error occurs since version 2.2.3. You can avoid this issue using version 2.1.6. pip install mysql-connector==2.1.6 try above. As of 2.2.3, Connector/Python uses a C++ extension that interfaces with a MySQL server with the X plugin enabled, using Protobuf as data interchange format. So, you need to set up where Protobuf is installed on your system (the library,
