SQL SERVER – Insert Multiple Records Using One Insert Statement

hmm this is interesting question
How can I insert multiple values in table using only one insert statement?
Normally when there are multiple records are to be inserted in the table we use following way in T-SQL.

INSERT INTO TestTable (TestColId, TestColTitle,TestColDesc)
        VALUES (1, 'TestVal1' ,'TestDesc1');
INSERT INTO TestTable (TestColId, TestColTitle,TestColDesc)
        VALUES (2, 'TestVal2' ,'TestDesc2');
INSERT INTO TestTable (TestColId, TestColTitle,TestColDesc)
        VALUES (3, 'TestVal3' ,'TestDesc3');
INSERT INTO TestTable (TestColId, TestColTitle,TestColDesc)
        VALUES (4, 'TestVal4' ,'TestDesc4');
INSERT INTO TestTable (TestColId, TestColTitle,TestColDesc)
        VALUES (5, 'TestVal5' ,'TestDesc5');

The clause INSERT INTO is repeated multiple times.
Many times DBA/Programmer copy and paste it to save time.
There is another alternative to this, which is easy to use without repetition of INSERT Clause.

For this use UNION ALL and INSERT INTO … SELECT… clauses.
I enjoy writing this way, as it keeps me focus on task, instead of copy paste of statement.
The effective result is same with less writing.

Regarding performance UNION ALL and INSERT INTO … SELECT… clauses performs better than normal Multiple INSERT Statement

INSERT INTO TestTable (TestColId, TestColTitle,TestColDesc)
SELECT 1, 'TestVal1' ,'TestDesc1'
SELECT 2, 'TestVal2' ,'TestDesc2'
SELECT 3, 'TestVal3' ,'TestDesc3'
SELECT 4, 'TestVal4' ,'TestDesc4'
SELECT 5, 'TestVal5' ,'TestDesc5'

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

Read and parse a CSV file into an array of rows and columns in C#

The following PopulateCsvIntoArraymethod used to read the CSV file into a two-dimensional array of strings.
I have included explanation of method lines, wherever needed. ///<summary> /// Populate the CSV file into an array, /// We assume that every line has the same number of fields and there may be blank lines. ///</summary> ///<returns></returns> privatestring[,] PopulateCsvIntoArray() { // Get path of CSV file. var path = Server.MapPath("~/Folder_Name/testfile.csv"); // Get the file's text using ReadAllText method. string fileData = System.IO.File.ReadAllText(path);
// Split CSV data into lines.     fileData = fileData.Replace('\n', '\r'); string[] lines = fileData.Split(newchar[] { '\r' }, StringSplitOptions.RemoveEmptyEntries);
// Get rows and columns counts. int totalRows = lines.Length;

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"
