To Backup all the SQL Server Databases

I came across this problem of backing up all the databases on my SQL servers (and there were 70 of them). I didn't want to back them up using the SQL Server GUI. While searching on the internet I got my hands on this script.

Delete SQL Jobs

Want to get rid of the SQL Jobs in your SQL Server? All of them are stored in msdb. You would need to run the following queries to remove them. If there is a scheduled time that this job runs at, you would need to first remove that.

Delete multiple databases in SQL Server

I've been into positions multiple times where I've to delete the databases in my SQL Server environment to clean up the QA environment or my local machine where I accumulate these test DBs over a period of time. If you are looking for one such situation here is the script that can come as a help -

Database Testing

Found this presentation on database testing on internet -

Delete and Truncate

Delete and Truncate are both commands in SQL to remove data from a table. But why do we have two commands? Are there any differences? YES! There are differences although the result is same. Both of them delete the data.

Inheritance

As we have already discussed in the previous post, OOPS characterizes objects by their class. So, if you only know the name of the class, you can name some of the characteristics of an object, such as even if you don't know what a BMW is, if someone tells you that it belongs to the class car, you would know the basic characteristics.

Normalization and De-Normalization

Database normalization is a data design and organization process applied to data structures based on rules that help building relational databases.  Normalization is done to achieve the following goals:

• eliminating redundant data (for example, storing the same data in more than one table)
• ensuring data dependencies make sense (only storing related data in a table).

Classes in OOP

A class is a blueprint or prototype from which objects are created. This section defines a class that models the state and behavior of a real-world object. It intentionally focuses on the basics, showing how even a simple class can cleanly model state and behavior.

SQL Server: Varchar v/s NVarchar

VARCHAR and NVARCHAR are two datatypes that are used in SQL Server very frequently and interchangeably. We would see what is the difference if any between these two:

OOPS-Building blocks-2

Continuing from the last post, we will look at what it means with

• abstraction
• polymorphism
• encapsulation
• event

OOPS-Building blocks

Here are the basic blocks:

• Class
• Objects
• Methods
• Inheritance
• Polymorphism
• Abstraction
• Event
• Encapsulation

Object Oriented Programming (OOPS)

OOPS is the Computer programming concept that breaks the problem into smaller objects similar to real life. Traditionally, computer programming used to emphasize on solving the problems with functions and procedures. For every task there would exist a function. This was good but was confusing with complex products and softwares. Moreover, the data used to suffer because of this approach.

Why geekiatrics?

I'm starting this blog to freshen up  my programming concepts. It's been more than 4 years that I finished my education and have since been working with an MNC. Somehow, I felt the need to go back to the basics and study again to be able to hold fort in the field.

and hence this blog was born. Over the next few months, I'll keep posting my learnings on this platform. Hope this would also help others.

Looking forward to the contribution from readers as well.
