SQLAlchemy Return All Distinct Column Values

Question

I am creating a website using Flask and SQLAlchemy. This website keeps track of classes that a student has taken. I would like to find a way to search my database using SQLAlc

Answer 1

As @van has pointed out, what you are looking for is:

session.query(your_table.column1.distinct()).all(); #SELECT DISTINCT(column1) FROM your_table

but I will add that in most cases, you are also looking to add another filter on the results. In which case you can do

session.query(your_table.column1.distinct()).filter_by(column2 = 'some_column2_value').all();

which translates to sql

SELECT DISTINCT(column1) FROM your_table WHERE column2 = 'some_column2_value';
