Syllabus

Projekt-Überblick

In diesem Projekt wirst du deine grundlegenden SQL-Kenntnisse auf Filterungen und Sortierungen erweitern! Filter durch Operatoren in SQL-Abfragen stellen sicher, dass nur die benötigten Daten im Ergebnis erscheinen. Sortierungen werden angewendet, um die Zeilen im Ergebnis so anzuordnen, dass der Nutzen für den Endbenutzer maximiert wird. Indem du Code zum Sortieren und Filtern in eine SQL-Abfrage steckst, machst du die Datenanalyse einfacher und ermöglichst effektivere Entscheidungen. Hier lernst du, wie du einfache und fortgeschrittene Vergleichsoperatoren wie LIKE, BETWEEEN oder CASE WHEN zu mächtigen SQL-Abfragen verbindest! Du lernst außerdem, mit fehlenden Werten umzugehen und komplexe Sortierungen zu erstellen. Du solltest schon grundlegende Kenntnisse der SQL-Syntax mitbringen, z.B. wie du eine SELECT-Abfrage schreibst. Am Ende des Kurses wirst du in der Lage sein, komplexere Filter und Sortierungen in SQL-Abfragen zu schreiben, um Informationen bedarfsgerecht für Endbenutzer aus einer Datenbank abzufragen.
