I have a python list, say l
l = [1,5,8]
I want to write a sql query to get the data for all the elements of the list, say
select name from students where id = |IN THE LIST l|
How do I accomplish this?
Now we will see solution for issue: python list in sql query as parameter [duplicate]
Answers so far have been templating the values into a plain SQL string. That’s absolutely fine for integers, but if we wanted to do it for strings we get the escaping issue.
Here’s a variant using a parameterised query that would work for both:
placeholder= '?' # For SQLite. See DBAPI paramstyle. placeholders= ', '.join(placeholder for unused in l) query= 'SELECT name FROM students WHERE id IN (%s)' % placeholders cursor.execute(query, l)
