Very basic and limited
This is a very, VERY basic primer for a very specific version of SQL
Description
1970 startete E.F. Codd mit seiner Veröffentlichung 'A relational model of data for large shared data banks, Communications of the ACM, Volume 13, Issue 6 (June 1970)' eine Revolution, die letztlich zu der heute allgegenwärtigen Datenbank-Anfragesprache SQL führte.
Diese kleine App zeigt für einige primitive und abgeleitete Operationen die folgenden Informationen:
* SQL92 und SQL86/89 Beispielanfragen,
* die Ergebnisse der Anfragen und
* Beschreibungen dazu.
Darüber hinaus kann man sich das SQL Testskript, das zur Berechnung der Beispiele verwendet wurde, anzeigen lassen.
Die App ist sowohl interessant für einen ersten Kontakt mit dem Thema Datenbank, als auch für alle, die seit nunmehr zwei Dekaden SQL86/89 Anfragen verwenden und nun endlich auf SQL92 umsteigen möchten ;)

Exactly what I was looking for
Simple, very very simple my only complaint is theres not enough content to really justify the app but I still like it
Отличная шпаргалка
Спасибо
Is what it says, elementary
Elementary SQL, very elementary. If you've written SQL on the job anywhere chances are this will teach you little to nothing. It's very bland though but is focused on simple presentation. If your learning or taking a class, the visuals are nice for things like outer joins. Good start!
Poor content
This app looked to have done in a hurry. Content is pretty weak.
Nice and simple
Nice ref I really like this app for quick lookup
Not very good
Just not good, not really useful.
