Dates not importing to SQL database correctly from Python

I have the following (subset of a) Pandas dataframe that I am trying to upload to a MySQL database: enter image description here

Here are details of the data using the info() function:

enter image description here

For added context, I previously converted both the tourn_date and date column to a datetime format using this code:

pd.to_datetime(all_data['tourn_date']).dt.date

Finally, here is the code that I'm using to import the data into the MySQL database:

for index, row in all_data.iterrows():
    inserts = [row.tourn_id, row.year, row.round_num, row.tourn_date, row.date]

    cursor.execute("""INSERT INTO AllPlayerStats 
                    (TourneyID, Year, RoundNum, TourneyDate, TDate)
                    values(%s,%s,%s,%s,%s)""", inserts)
db.commit()
cursor.close()

However, when I run this, some of the dates (like the ones shown above), are appearing as NULL in the database (see below) despite other tournaments working just fine and the format of the TourneyDate and Date columns in the database being of date type. In some instances, the tourn_date uploads correctly but the date doesn't.

enter image description here

Is there a way to troubleshoot this and understand why this is occurring? I'm very confused as to what's going on here.

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
