Practicing SQL should also be hassle-free and (yes!) fun. With Knowledify, you will play the role of a freshly hired employee. Through a series of assignments more and more complex around the new database system that you new employer has deployed, you will move up within the company and become masterful in the art of SQL.
› Assignments increase in complexity and breadth as you progress
› Explore through practical training advanced usage of the language
› Consult contextual reference articles as you are practicing
› Intellisense and code-completion allows you to quickly write up complex queries
Why should you install Knowledify?
› Practice on statements and SQL constructs that you may have forgotten
› Prepare for exams (certification, interview, or university-level exams)
› Maintain and also enrich your knowledge in SQL
This app is unique in that it helps you master the most commonly asked questions, instilling you with the confidence that you need to endure the most difficult of interviews. Application covers all Common questions and also questions specific to any particular database.

1. 164 questions that prepare you for any type of interview.
2. Provide an option for user to practice his/her own answers as your application will present your with question. User can think of his answer then compare how his answer is different from our answer.
3. Interview Questions has been categories for ease of use.
4. Check out common question then check specific question related to the dabase of your choice.
Q. ) What is the difference between TRUNCATE and DELETE commands?
Ans: Both will result in deleting all the rows in the table .TRUNCATE call cannot be rolled back as it is a DDL command and all memory space for that table is released back to the server. TRUNCATE is much faster.Whereas DELETE call is an DML command and can be rolled back.
Q.) What is a candidate key?
Ans : A table may have more than one combination of columns that could uniquely identify the rows in a table; each combination is a candidate key.
App includes Normalization, SQL Joins, SQL Functions, SQL Commands, Queries/Corelated queries , Constraints, Cursor, Stored Procedure, User Defined functions, views, exception handling & SQL best practices.

"SQL ist eine Datenbanksprache zur Definition von Datenstrukturen in relationalen Datenbanken sowie zum Bearbeiten (Einfügen, Verändern, Löschen) und Abfragen von darauf basierenden Datenbeständen." - Wikipedia
Der Fokus steht auf den Select-Abfrage, die für die technischen Gymnasien Abitur-relevant sind. Anhand von interaktiven Übungen mit einer echten Datenbank, welche in der App integriert ist, wird das Wissen unvergesslich eingeprägt. Zur Bearbeitung der aktuell 18 Kapitel, sind gewisse Grundkenntnisse vorausgesetzt.
- dynamische Oberfläche (sowohl für Smartphones, als auch für Tablets geeignet)
- einfache Bedienung
- schlichte, übersichtliche Oberfläche
- praktisches Lernen für unterwegs
- gute Ergänzung zum herkömmlichen Schulmaterial
- KEINE Berechtigungen erforderlich
- keine Systemvoraussetzungen
Eine Vollständigkeit oder absolute Korrektheit der Informationen kann natürlich nicht gewährleistet werden! Die App sollte insbesondere zur Wiederholung bzw. zur Ergänzung des Unterrichtthemas verwendet werden.
Die App befindet sich noch in der Entwicklung, sollte es also Grund zur Beschwerde/ Unzufriedenheit geben, würde ich mich über eine E-Mail mit einer Beschreibung der Problematik freuen.

SQL can be used to access and manipulate data in: MySQL, SQL Server, Access, Oracle, Sybase, DB2, and other database systems.
SQL is commonly used in one of two ways:
1. Directly operate on the database management system (DBMS), or
2. Operate on the database management system as part of a larger application
What Can SQL do?
SQL can perform a variety of database related operations, including:
- Executing queries (finding data)
- Retrieving data
- Inserting records
- Updating records
- Deleting records
- Creating new databases
- Creating new tables
- Creating stored procedures
- Creating views
- Setting permissions
What is a Database?
In general, a database consists of one or more tables. Each table is identified by a name and contain rows (also called records) and columns containing data.
SQL is an ANSI (American National Standards Institute) standard
To build a web site that shows data from a database, you will need:
- Using An RDBMS database program (i.e. MS Access, SQL Server, MySQL)
- Using a server-side scripting language, like PHP or ASP
- Using SQL to get the data you want
- Using HTMLand or CSS
Web Sites and SQL
Most modern websites make use of a RDBMS (Relational Database Management System) to manage their data. The data in the RDBMS is stored in database objects called tables. A table is a collection of related data entries and it consists of rows and columns.
In general, these websites need the following components:
- An RDBMS database program (i.e. MS Access, SQL Server, MySQL)
- A server-side scripting language, like PHP or ASP
You can use this application to if you want to get ready for interviews, or just to refresh your basic Sql Queries knowledge.
If you are an interviewer you can also use this application to get ideas for questions.
* Auto reading of the Questions And Answers
* Share your notes via e-mail, SMS, and etc.;
If you are one of those who go scurrying away in opposite direction with the sight of lizards then you might be facing Herpetophobia which 57% of the world population face.
So if you are getting nightmares of 3-inch creeps much scarier than Godzilla this is the app for you. Warding off lizards has never been so easy as you don't even have to clear the mess as our repellent won't let lizards to settle down.
