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 +...

Bytes to TeraBytes.

Converting from bytes to terabytes is very easy considering that terabyte = 1024*Gigabyte              = 1024 * 1024 * Megabyte              = 1024 * 1024 * 1024 KiloByte              = 1024 * 1024 * 1024 * 1024 * Byte Query below gives number of documents in a media and the total size of the documents. See how you have used Alias in the query SELECT        [MEDIA] = X.media_id,         [TOTAL] = COUNT(*),       [Size_KB] = SUM (Size_MB) FROM       (       SELECT              d.edoc_id,              d.media_id ,             SIZE_MB =  (                         CAST(ISNULL(d.Size1,0) AS DECIMAL) +      ...
