## SQL Primer Description
1970 E.F. Codd has started a revolution with his paper 'A relational model of data for large shared data banks, Communications of the ACM, Volume 13, Issue 6 (June 1970)' that finally led to the today's omnipresent database query language SQL.

This little app shows some primitive and derived operations with the following information:
* SQL92 and SQL86/89 sample queries,
* the results of the queries and
* appropriate descriptions.

Furthermore the SQL test script that has been used for the calculation of the samples can be displayed.

The app is interesting for the first contact with the database subject and for all who are using SQL86/89 queries for over two decades now and finally want to change to SQL92 also ;)

## SQL Primer Reviews in United States

### *---- "Very basic and limited"
This is a very, VERY basic primer for a very specific version of SQL
-- NuZooRevue, 2025-02-21

### ***** "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
-- Ddd1600, 2014-02-28

### ***** "Отличная шпаргалка"
Спасибо
-- Qwertyппппр, 2013-04-05

### ****- "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!
-- Mohgeroth, 2013-02-13

### **--- "Poor content"
This app looked to have done in a hurry. Content is pretty weak.
-- Kale238, 2012-12-27

### ***** "Nice and simple"
Nice ref
I really like this app for quick lookup
-- Piggyho, 2012-01-20

### **--- "Not very good"
Just not good, not really useful.
-- PenThAng, 2011-05-13

### ***** "Good beginning primer"
Excellent for beginners using basic syntax example & explanations. Look forward to more advanced priming!
-- Keither713, 2010-10-13

### ****- "Cool"
Thanks good stuff
-- ttim6575, 2010-07-11

### ****- "request"
firmware 3.1.2 version support please.
-- 동기화, 2010-06-11
