SQL topics
12 short topics in SQL and Relational Databases. Each one is a single focused exercise with a clear piece of evidence at the end.
12 topics, one exercise each.
Work through them in order, or jump to the one you need.
These are draft topic outlines (draft; instructor review pending). Full lessons follow after review; ask Ajay if you need a topic sooner.

Query expression syntax
Demonstrate query expression syntax in a focused SQL example; verify normal behavior and one edge or failure case. Keep the exercise bounded and record the behavior supported by the chosen version.
Open micro-course → - 02
Data selection and projection
Demonstrate data selection and projection in a focused SQL example; verify normal behavior and one edge or failure case. Keep the exercise bounded and record the behavior supported by the chosen version.
Open micro-course → - 03
Predicates and filtering
Demonstrate predicates and filtering in a focused SQL example; verify normal behavior and one edge or failure case. Keep the exercise bounded and record the behavior supported by the chosen version.
Open micro-course → - 04
Grouping and aggregation
Demonstrate grouping and aggregation in a focused SQL example; verify normal behavior and one edge or failure case. Keep the exercise bounded and record the behavior supported by the chosen version.

Learn the same ideas beyond SQL.
These courses share topics with this one, so you can compare how each language or tool handles the same concept.
