SQL Server: What is the difference between DELETE and TRUNCATE command?

Following are the differences between DELETE and TRUNCATE:

TRUNCATE is DDL Statement
DELETE is a DML command
TRUNCATE cannot have WHERE Conditions
DELETE can have WHERE conditions
TRUNCATE does not fire trigger
TRUNCATE reset the identity to 0 (if table have any)
DELETE does not RESET Identity
TRUNCATE Release the table’s spaces to System
DELETE removes the records but will not release the space to the system
TRUNCATE cannot be used against the table that is referenced by a FOREIGN KEY constraint.
DELETE can be used in tables reference by a Foreign Key and tables involved in Indexed view
TRUNCATE cannot be used against the table used in Indexed view
DELETE can be used against the table used in Indexed view
TRUNCATE apply Fewer table locks
DELETE apply more locks to the table
TRUNCATE cannot be used against the tables involved in TRUNCATE transactional replication or merge replication.
DELETE can be used against table used transactional replication or merge replication
Less Transaction Log entry because TRUNCATE TABLE removes the data by de-allocating the data pages used to store the table data and records only the page de-allocations in the transaction log and hence TRUNCATE is fast
DELETE FROM TABLE command logs each record in transaction log, hence DELETE is slow.

Note: TRUNCATE can be roll backed. Many programmers think that TRUNCATE can’t be roll backed.

C#: Merging Excel cells with NPOI HSSFWorkbook

In this post we’ll see how to merge the two or more cell with each other while creating the excel sheet using NPOI.
Mentioned below is code to merge multiple cells, in this example we are merging first cell to fifth cell of first row (you can adjust row or cell range by passing particular parameters in CellRangeAddress).
//Created new Workbook var hwb = new NPOI.HSSF.UserModel.HSSFWorkbook(); //Create worksheet with name. var sheet = hwb.CreateSheet("new sheet"); //Create row and cell. var row = sheet.CreateRow(0); var cell = row.CreateCell(0); ; //Set text inside cell cell.SetCellValue("This is Merged cell"); cell.CellStyle.WrapText = true; //define cell range address // parameters: -> first row to last and first cell to last cell var cra = new NPOI.SS.Util.CellRangeAddress(0, 0, 0, 4); //Add merged region to sheet. sheet.AddMergedRegion(cra);
Hope this solution helps you J

Calculate Sum and average of two or more Textbox values using JQuery

We can calculate sum and average of values entered in textboxes with the help of small piece of jQuery code.
First of all let’s create a HTML form where we’ll ask user to enter marks in each subject, under body section add following HTML:
<tableclass="demo-table"> <trclass="label"> <tdcolspan="2">Please enter marks(0-99):</td> </tr> <tr> <td>English</td> <td> <inputtype="text"class="txtMarks"name="txtMarks"

Difference between Web API, WCF and Web Service

So now we have got the basic idea about Web API, now let’s do some comparison of Web API with WCF and web services.
Web Service WCF Web API Web services created as file with .asmx extension. WCF create with .svc extension Web API are simple class file with .cs(for C#) extension. Web API is inherited from “ApiController” and class name must end with “Controller”. It is SOAP based service and return data in XML form. It is also based on SOAP and return data in XML form.
