DBIS SQL Exercise Generator

Installation

Install via pip:

# Not yet available on PyPI
pip install dbis-sql-exercise-generator

Most notably, following required packages are also installed:

• dbis-sql
• dbis-exc-manager

Usage

from rc_exercise_generator import generate_exercise

# set the solution as SQLite query (string)
solution_sql_query = "SELECT a, c FROM R;"

from excmanager.Task import Exercise, Task, SubTask
exercise1 = Exercise(1)
task1 = Task(exercise1, "1.1")
subtask1 = SubTask(task1, "a", points=2)
# task description
description = "Select the attributes a and c from the relation R."

generated_cells = generate_exercise(
	subtask1,
	description,
	solution_sql_query,
	correct_attributes_score_perc=0.1,
)

# generated_cells is a dictionary of cells, which can be used to generate a Jupyter Notebook
# format:
# filename (str) -> cell content (str)

:warning: Guidelines

In order to directly use the generated cells in an exercise Jupyter notebook, one should follow the following guidelines:

• tasks should be named task1, task2, ...
• The SQLite Connection has to be made beforehand. This connection should be stored in the variable sql_con.
