SQL - Naming Convention

Naming Convention in SQL


Stored Procedure. 

sp<Application Name>_[<group name >_]<action type><table name or logical instance> Where action is: Get, Delete, Update, Write, Archive, Insert… i.e. verb 
Example: spApplicationName_GetUserDetails
       spApplicationName_UpdateEmails

Note :Do not prefix stored procedure names with “SP_”, as “SP_” is reserved for system stored procedures.

Triggers:

TR_<TableName>_<action><description> 
Example: TR_Emails_LogEmailChanges , TR_UserDetails_UpdateUserName

Indexes : 

IX_<tablename>_<columns separated by_> 
Example: IX_UserDetails_UserID

Primary Key :

PK_<tablename> 
Example: PK_UserDetails
PK_ Emails

Foreign Key : FK_<tablename_1>_<tablename_2> 
Example: FK_UserDetails_Emails

Default: 

DF_<table name>_<column name> 
Example: DF_ UserDetails _UserName

Tables, Views, Stored Procedures. 
- use pascal notation eg: UserDetails
- should end with 's' eg: Emails

If you have big subset of table group than it makes sense to give prefix for this table group. Prefix should be separated by _.  eg: edr_Doc

JavaScript Interview Questions

This is a compilations of all the interview questions related to Javascript that i have encountered.  Q: Difference between window.onload and onDocumentReady? A: The onload event does not fire until every last piece of the page is loaded, this includes css and images, which means there’s a huge delay before any code is executed. That isnt what we want. We just want to wait until the DOM is loaded and is able to be manipulated. onDocumentReady allows the programmer to do that. Q:  What is the difference between == and === ? A: The == checks for value equality, but === checks for both type and value. Few examples: "1" == 1; // value evaluation only, yields true "1" === 1; // value and type evaluation, yields false "1" == true; // "1" as boolean is true, value evaluation only, yields true "1" === false; // value and type evaluation, yields false Q: What does “1″+2+5 evaluate to? What about 5 + 2 +...

ASP.NET Basics

ASP.NET is a server side technology for developing web based applications based on Microsoft .Net  Framework. ASP.NET is run on the web server. When a user click on a page/website link on a web browser, a request is sent to the web server. The web server reads the code and generates a web page . The web page is then sent to the browser where the client reads this page. Since the processing is on the server, it is called 'Server Side technology'. Features of ASP.NET: It lets you write server side code using over 40 languages. Most popular being C# and VB ASP.NET pages are compiled, not interpreted It has full access to the functionality  of .Net Framework... XML, web services, database interaction, emails, regular expression You can separate server side code of your page from HTML layout Easy to reuse common User Interface elements An ASP.NET page generally consists of the following: 1. Directive: Controls how page is compiles , how page is cached by web browser, err...

Adding a linked Server using the GUI

Adding a linked Server using the GUI There are two ways to add another SQL Server as a linked server.  Using the first method, you need to specify the actual server name as the “linked server name”.  What this means is that everytime you want to reference the linked server in code, you will use the remote server’s name.  This may not be beneficial because if the linked server’s name changes, then you will have to also change all the code that references the linked server.  I like to avoid this method even though it is easier to initially setup.  The rest of the steps will guide you through setting up a linked server with a custom name: To add a linked server using SSMS (SQL Server Management Studio), open the server you want to create a link from in object explorer. In SSMS, Expand Server Objects -> Linked Servers -> (Right click on the Linked Server Folder and select “New Linked Server”) Add New Linked Server The “New Linked Server” Dialog a...
