What you need to compare is the result from your ps.executeQuery();
which is assigned to ResultSet rs
.
Read the ResultSet javadoc to understand how you can extract data from it - https://docs.oracle.com/javase/8/docs/api/java/sql/ResultSet.html.

...ANSWER
Answered 2021-Jun-13 at 13:35Are you trying to iterate both on "df" and "base" rows? If so, you have to slice the "df" to get the value for the columns at the row (using iloc - https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.Series.iloc.html - or loc - https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.loc.html). The comparissons on the if and elif conditions returns Series, not a single boolean. If you absolutely have to take this approach on having both "df" and "base", I'd sugest:

await ctx.send(f"{member.mention}merci de clear entre 0-200 message(s)")
else:
await ctx.send(f"j'ai clear {amount} message(s)",delete_after=5)```
...ANSWER
Answered 2021-May-26 at 20:16Here are some errors that I noticed:
First) Since you are looking for the author of the message, member
is not relevant here at all. We can simply use ctx.author
for this and then display it as desired.
Second) You have a logic error in your code. Your if amount >200
statement is not considered the way your code is and then more than 200 messages can be deleted without the error message showing up.
One possible code would be:

Answered 2021-Mar-18 at 18:23Welcome to Dart. What you are experience is the new null-safety feature (introduced with Dart 2.12.0) where variables by default cannot contain the value null. This is statically checked so you will get an error even before your program are executed.
In your example the problem is the following line:
