ASP.NET Hosting - ASPHostPortal.com :: Easy steps to delete duplicate rows from table in sql server

clock November 4, 2016 11:25 by author Dan

Based on ASP.NET Corner blog. I have two columns Name and Age in my Table(MyTable). From the MyTable I want to delete only duplicate records. So the below Query will help you to delete or remove the duplicate rows from the MyTable.

Below is MyTable output:

SELECT * FROM MyTable

Current output:

Name    Age
vijay    30
antony    40
Aruna    28
antony    40
chander35
mark    42
vijay    30

Remove duplicate rows from the table:
The below query will help you to delete duplicate row from your table. Here we used Row_Number() function and PARTITION BY key words to remove the duplicate rows.

DELETE SUB FROM
(SELECT ROW_NUMBER() OVER (PARTITION BY Name, Age ORDER BY Name) cnt
 FROM MyTable) SUB
WHERE SUB.Cnt > 1


After the query execution the output is:

Name    Age
Aruna    28
antony    40
chander    35
mark    42
vijay    30

How to use Row_Number in SQL Select query:

SELECT ROW_NUMBER() OVER(ORDER BY Age) FROM mytable

ASP.NET Hosting - ASPHostPortal.com :: SQL Split Function to Split an Input String

clock September 28, 2015 06:02 by author Dan

Today, we will explain about SQL Split Function to Split an Input String. Generally when posting an article in a blog, we have to define tags (Like  C#.NET, AJAX, ASP.NET,HTML) upon the article. We usually take these tags in a TextBox with separated them by comma(,). To insert these into database we have two ways to do.

First Method using C# :

Using C# you can split the TextBox items and use a for loop to insert into the database. Code is as follow.
   
string []tags = txtTags.Text.<span class="IL_AD" id="IL_AD10">Trim</span>().Split(',');
 
/* With for loop */
for (int i=0;i<tags.Count ;i++)
{
 /* perform db query with tags[i].ToSting();
}
 
/* with foreach */
foreach (string i in tags)
{
  /* perform db query with i.ToSting();
}

Second SQL Method :

Here in the SQL we pass the whole items of TextBox into SQL function to split it and then insert these into specific table. Lets see how to do this.
   
CREATE FUNCTION SplitText
(   
      @Input NVARCHAR(MAX),
      @Character CHAR(1)
)
RETURNS @Output TABLE (
      Item NVARCHAR(1000)
)
AS
BEGIN
      DECLARE @StartIndex INT, @EndIndex INT
 
      SET @StartIndex = 1
      IF SUBSTRING(@Input, LEN(@Input) - 1, LEN(@Input)) <> @Character
      BEGIN
            SET @Input = @Input + @Character
      END
 
      WHILE CHARINDEX(@Character, @Input) > 0
      BEGIN
            SET @EndIndex = CHARINDEX(@Character, @Input)
           
            INSERT INTO @Output(Item)
            <span class="IL_AD" id="IL_AD12">SELECT</span> SUBSTRING(@Input, @StartIndex, @EndIndex - 1)
           
            SET @Input = SUBSTRING(@Input, @EndIndex + 1, LEN(@Input))
      END
 
      RETURN
END
GO
 
-- Create a temporary table to insert tags
create #tblTemp
(
Id identity (1,1),
tag nvarchar(50)
)
 
-- Inserting into tmpTable
insert into #tblTemp (temp) values
SELECT Item FROM dbo.SplitText('ASP.NET,C#.NET,ADO.NET,JavaScript', ',') 
-- Seperated by Comma(,). Place any thing according to you.


Execute your SQL batch query to inserting the tags into table.
