Getting the input List of a WHERE IN Filter for SQL QUERY From A File or a Local Table
I have a simple SQL Query. However, the query has a where filter which takes a list.
The list contains at least 2000 items and it is becoming extremely inconvenient to put the long list into the query itself.
I was trying to find if I can create a table/ file and call that into the query instead.
EXAMPLE CODE:
Select * from Table_XXXX where aa = 'yy' and date > zzz and mylist = [..............]
So instead of the list above, I will like to call the file (locally) in which the elements of the list reside or a table (locally and not in the database) in which the elements are in a column...
Any help will be appreciated.

At that point it's probably best to put all the items into a temporary table and use it as a subquery withINorEXISTS, or as part of a join.

Neither of your preferred options are possible in mysql , I don't know about pandas.

First you would store the contents of the file/list in a table. And after that you can use the in condition
create table mylist(x int);
insert into mylist values(<all values in your file>);
select *
from Table_XXXX tt
where tt.aa = 'yy'
and tt.date > zzz
and tt.mylist IN (select x from mylist)

Thanks George. However, I did not get the second line.. Is the insert into my list a function in sql? How can I get the values from file->table->list. Sorry for my ignorance.
