CTE & RECURSIVE CTE(Common Table Expression)

Common Table Expression

Simple CTE

Print 1 to N numbers

;
WITH CTE AS
(
    SELECT NoM=1
    UNION ALL
    SELECT NoM+1 FROM CTE WHERE NOM+1<=10
) SELECT * FROM CTE

Ans:

Find the Employees under manager 

;WITH X AS
(
    SELECT * FROM EMP WHERE mgr=7788
    UNION ALL
    SELECT e.* FROM x  INNER JOIN emp e ON e.empno=x.mgr
)
SELECT * FROM X

Ans:

Find Cumulative Salary of employees 

select SAL,(select SUM(sal) from emp e where e.empno<=a.empno)as CUM_SAL from emp a

FUNCTION TO concatenate all COLUMNS OF a TABLE

FUNCTION TO concatenate all COLUMNS OF a TABLE 

USE AdventureWorksDW2008

CREATE FUNCTION fn_columns( @tblname varchar(50))
returns varchar(MAX)
as
BEGIN
DECLARE @name VARCHAR(500)=''

Script Task For Pickup txt file From Folder

Step 1:
Create Two variables as shown in figure
One for Fullpath STRING
Another for Validate INT

Step 2:
In script task Editor Select valiadate variable as a Readonly variable and other for Readand write variable

"D:\\ExcelDestination\\ExcelWorkBook_"+ (DT_STR, 4, 1252) DATEPART("yy" , GETDATE())  +
RIGHT("0" + (DT_STR, 2, 1252) DATEPART("mm" , GETDATE()), 2)  + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("dd" , GETDATE()), 2)+".xlsx"

Step 3:
Click on edit script then write like as shown in last image
Save then click OK

using System.IO;

public void Main()
{
// TODO: Add your code here
            String str = Dts.Variables["User::FullPath"].Value.ToString();
            if (File.Exists(str))
            {
                Dts.Variables["User::Validate"].Value = 1;
            }
            MessageBox.Show(str);
            MessageBox.Show(Dts.Variables["User::FullPath"].Value.ToString());


Dts.TaskResult = (int)ScriptResults.Success;
}

Step 4:
Go to properties of Fullpath by selecting that variable and click F4---->Expression--->Write expression shown in image Expression Builder--->Evaluate expression

Step 5:
Click on presidence constraint--> Evaluation and Constraint-->@validate ==1
in other line keep @validate==0
