SSIS - Creating SQL server Agent Proxy Account for SSIS Package Execution

       When you are trying to perform some file system task in SSIS or while attempting to read/write some files from the remote locations, the job which uses SSIS package will require the permission to access the network location.
       If your windows NT account has all the rights to access the particular loaction then the package will work fine while runnig the package from BIDS. But the same will not work if you run the package from SQL Server Agent Job. Since the SQL Server Agent will be running on the 'sa' account by default. And this SQL admin will not have permission to access the file sytems.
      So, to make it run from the SQL Server Agent, we have to create new credential (of Windows NT account) which will have all the access to the specific file server or network location.
       And we have to create Proxy for the SQL Server Agent which uses the newly created credential. And the Proxy should be associated with the Subsystem SSIS.

 Please find the detailed steps written in the following blogs :

Search the Column on the DB (SQL Server)

          To find a particular column from all the tables available on the particular  DB, We can use the following sql query :

SELECT tab.name AS table_name,

col.name AS column_name

FROM sys.tables AS tab

INNER JOIN sys.columns col ON tab.object_id  = col.object_id

WHERE col.name LIKE '%SalesDoc%'  -- Column Name

SSRS - Implementing Drill Through action in the same RDL

Scenario:

           User wants a SSRS Chart report which will display the Product Category wise Sales in the initial view. On clicking of the bar chart, the report should display the Product wise Sales of that selected Category.

          We can enable this drill through action in a single RDL as given below.

Note :  I haven't given the SSRS chart creation steps detaisl by considering that the reader knows how to create SSRS Chart reports. 

To implement the above said requirement, we can do some tweaks in the SQL query if the report data set and achieve the same.

The given below sample query can be used in the data set, which will return the Category wise sales if the in parameter (@ProdCategory) value is not available in the Category table.

if exists(

select 'x' from dbo.Dim_Category  where Category=@ProdCategory

    )

begin

select ProductName as Item ,SalesAmt as Sales_Amt from dbo.Dim_Category where Category=@ProdCategory

end

else

begin

select Category as Item,sum(SalesAmt) Sales_Amt from dbo.Dim_Category group by Category

end

Follow the given below steps:

-In the above created Dataset, @ProdCategory is parameter and its default value is 'a' initially.

-Create a Chart report and drag the field Item in to the category field and Sales_Amt into the Data field of the chart.

-In the Action pane write an expression to Go to this same report in the Chart series

-Pass the Field ‘Item’ as a parameter to the report

-On clicking on the Category that Category will be taken as a new parameter. And new result set for the selected Category (Products under the selected Category) will be produced in the same report.

-Now, when the report initially gets opened, the default parameter will be passed to the data set and the value will not be available in the Dim_category table, and the report will generate Category wise Sales Amount in the Chart.

-If the user clicks on the Category series, then the selected Category will be passed as an in parameter to eth data set and the selected categories Products will be returned by the data set and the chart will provide the Product wise Sales amount. 

To Find Duplicate Rows using Common Table Expressions and perform DML operations

Handling the Duplicates using CTE and Row_Number()  - (ie, To Delete or Update the Duplicates from SQL server Tables Using CTE, Row_Number() ) 

            Just to select the duplicate rows from a table, we can use the following kind of simple query. The below mentioned query will return duplicated rows based on the Product_Id :

                     

SELECT Product_id,

      COUNT(Product_id) AS NumOccurrences

FROM InventoryDetail

      GROUP BY Product_id

      HAVING ( COUNT(Product_id) > 1 )

If you want to Delete or Update the duplicate, we can use the following sample which will use the CTE (Common Table Expression) , Row_Number function and the MDL statement (Delete/ Update).

            

                      

WITH CTE (Product_id,Time_Id, DuplicateCount)

AS

(    

      SELECT Product_id,Time_Id,

                  ROW_NUMBER() OVER(PARTITION BY Product_id,Time_Id ORDER BY Product_id) AS DuplicateCount

      FROM InventoryDetail

)

DELETE

      FROM CTE

WHERE DuplicateCount > 1

SSRS : New Line Expression

SSRS : New Line Expression

       If you want to display the text in a new line at the text box, the following expression can be used.

="Line 1 " + VBCRLF + "Line 2"

Ex : =Fields!AddressLine1 + VBCRLF + Fields!AddressLine2 + VBCRLF + Fields!AddressLine3

OP:
 Address1
 Address2
 Address3

Note: If VBCRLF is used first or last part the expression, it has no impact on result. If you want a line in the first or last, then use one more extra VBCRLF.
