Step by Step SSIS Multicast Transformation TIP #121

Dear Friends,

This is another post in the series of step by step SSIS ,Zero to hero series. In this post we will discuss another transformation control which is Multicast transformation.

Multicast is a way which help us to provide multiple copy of same source data for different transformation. Or in other words we can say multicast transformation create multiple pipelines for the same data.

Lets understand this by an example. Suppose, we are product developer and selling product in different state in India. Now ,the problem is same product may have different selling price due to different tax system. So, we have to use same data of product but there will be different discount according to sate tax.

Now, here we go step by step. for your information in this example we are going to use similar example which we did in last post of Derived column Transformation tip #120

Step 1:- Add a package and drag drop data flow task and configure source database. I am taking Adventurework2012 database and using product &  productCategory tables for source data query below is simple snap of data

Step 2:- Once the data is configured. Drag drop Multicast control  as shown in below figure and give output of source object to Multicast and try to configure it.

Step 3:- Now, when we have configured Multicast we can get multiple output from Multicast control. Suppose , One state is taking 10% WAT tax, another state taking 20% WAT tax and last one is taking no tax (wow that’s great). So we can drag drop derived column and configure then according to 10% ,20% WAT tax for reference you can take a look of tip #120 

I configured the the 3 different output in same way and adding the respective flat files. As shown in below figure you will see we added 3 files

1) with 10% ,with 20 % and without and tax

After configuration you will get structure something like as shown in below image. As a result we will get 3 flat files with 10% ,20% and without any change.

Step 4:- If you face any difficulty in Derived column configuration and moving the data to file please follow earlier post. Now once everything is configured run the package by pressing F5 or hitting run button you will get following screen. So , if you see Multicast providing similar row count to different output which is 295 rows.

We , can use this Multicast where we need multiple copy of same source data.

I hope this article might help you somewhere.

Step by Step SSIS–Derived Column Transformation TIP # 120

Dear Friends,

In the series of Step by Step SSIS , Zero to Hero in SSIS this is another post in which we will try to understand what is Derived Column Transformation.

Let’s understand this by a real world example. Suppose, we are a shop keeper and our work is buy things from carpenter and sell them by adding our 20%  margin.

So , carpenters give us source data (file, sql server etc) with their rate according to product. What we do actually ,we add another column in our register by adding 20% which is our selling price. So ,our selling price column is a derived column here which we derived from source by adding some of our operations.

Isn’t it simple ?

Let’s understand this now step by step. I am using Adventureworks2012 database here as a source database and using product & ProductCategory table combination query. So , Assume this source data is data of carpenter’s products.  Here if you see below image we have productId, Product Name, color,Category & ListPrice (price at which we (Shop Keeper bought the the product)

Step 1:- It is useless to say here add a new Package in your project. Drag drop data flow task on canvas. Now double click the data flow task you will get a new screen where you need to drag drop source Assistance.

Now,need to configure source assistance where database will be adveturework2012.  If you see below we have same columns which we shared earlier in figure

Step 2:- I am sure you will not face any problem in configuration of source control. Now in step 2 we have to drag drop Derived column.  Once you drag drop derived column you need to provide output of source assistance to Derived Column Transformation. Now to configure this use context menu by right clicking and choose Edit option you will get below screen. Here we have different functions and operators which we can be utilized with columns and variables and parameters to create derived column.

If you see above highlighted row in image we can add a new column or can replace any existing column as shown in drop down.

Step 3:- If you see there is expression column also where we can add custom expression. Here we are multiplying 0.20 in list price and adding it again in Listprice and aliasing this new column SellingRate as shown in below figure

if you see below screenshot we can add other functions ,operators also.

Step 4:- I hope above steps are pretty much clear. Now add a destination file in which we will get derived column “SellingRate” . We have to configured the derived column. As shown in below figure we configured derived column.

Step 5:- Now, Once the destination file is configured run the package by pressing F5 or clicking run option. If everything working fine then we will get all the green checkbox sign as shown below figure

I hope this post might help you to understand the derived column.

Enjoy !!!

Step by Step SSIS–Union ALL Tip # 119

 

Dear All,

In the series of  zero to hero SSIS series this is one of the simplest transformation control which known as UNION ALL. 

As you might aware UNION in general term  which means collective. In SSIS UNION all control is doing the same task.

It collect all the inputs may be of same type of sources or different type of sources and  union them all and provides single output for the same.

Lets understand this by below example.

Suppose, We have different text files which contain fruits &  vegetables name. Now our aim is to combine all the fruits and vegetables name which exists in these files.

if you see below image you will find 3 files which FruitA (Contains fruit names start with letter A) , FruitB (Contain fruit names start with  letter B), FruitP (contains fruit name start with letter P)

Now we need to combine this file using UNION ALL transformation. So follow below step by step

1) Step 1:- Step 1 is simplest step and now you all well versed in this. We need to add a new SSIS package file and drag drop  data flow task .

2) Step 2:- Now add different flat file source for all the 3 files and configure all the 3 files  fruitA.txt, fruitB.txt , fruitP.txt .

3) Once we configured all the 3 flat file sources, We have to drag drop UNION ALL transformation control.Once we drag drop UNION ALL we can provide the output of all the 3 files as a input in UNION ALL control as shown in below  figure.

Step 4:- Now, we have to configure the UNION ALL control. To do this right click on UNION ALL control and click on EDIT option. Here we have to configure all the columns which we need to union.

Step 5:- Once the UNION ALL is configured our next step is to get the output of UNION ALL in a resultant file. for this we have to drag drop destination flat file control as shown in below figure.

Step 6:- Now we have to configure the flat file destination and save it to specific location. A part from this we have to provide input to flat file destination which will be output of UNION ALL control. As shown in below figure I am saving the file on same location and giving name finaloutput.txt

Step 7:- Once all the above step is processed by us the final step is to run the package for this just click on RUN icon or hit F5. If everything is working fine the we will get following  result with all the green right check images.

If you see above image we did union of all the 3 files and saved output in a single file.

Now, for learning purpose and to make the post simplest I use only same type source you can use different type of source and destination as per your need.

A part from this UNION ALL doesn’t remove duplicate so if there are duplicates in the files it will not remove.

I hope this article will help you somewhere.  Please provide your inputs.

Enjoy !!!

Step by Step SSIS–Aggregate Transformation TIP #118

 

Dear Friends,

In the series of step by step SSIS tutorial this is another post. In this post we will see Aggregate Transformation. I am pretty much sure you are aware of aggregation. Although , Just wanted to share that aggregation operation in generally memory expensive operation.

So, whenever you want aggregation & want to use group by function then in such situation you can use Aggregation transformation.

There are different group by option available like MIN, MAX , COUNT, SUM, AVERAGE etc.

Let’s understand how to use Aggregate transformation step by step.

For current example we are using Adventureworks database and we are using below query. Here we are fetching the product data with line total,unit price  & other details.

if you see the records in the table you will find that there are multiple records for same product with different line total.

Our objective is to aggregate or do sum of Line total according to Line Number and export the result in a csv.

Step 1:- So , Now start with package creation add a new package in solution and drag drop source Assistant and configure the database connection as we did earlier in the tutorials

Step 1.1 – Drag drop  Data flow task

Step 1.2 – double click data flow task  and drag drop source assistance control

Step 1.3 – Configure source assistance

Step 2: Once the source assistance is configured with SQL SERVER connection string and specific query we will drag drop Aggregate Transformation control as shown in below figure

Step 3:- Now configure this aggregate control. So Just right click aggregate control and select Edit option. Now as we require Sum of LineTotal so we have selected SUM in operation column’s drop down and rest other has drop down option group by.

 

Step 4:-

Now, drag drop flat file destination and configure it.

Now configure flat file  with mapping as shown in below figures

Step 5: Now run it you will get desire result as shown in below figure

If you see in the result we got 757 rows after processing 121,317

Now see the result in actual as shown in below file

I hope this example might help you to understand Aggregate transformation. Please provide your inputs.

Enjoy !!

How to use SORT control in SSIS ? TIP #115

Dear Friends,

In the series of Learn SSIS step by step this is the 5th post. Now from this post we are going to use each transformation control one by one.

So, lets start with simplest one transformation control which is “Sort”.

By the name it is clear data it will sort the data which is provided to it and give sorted output as a result. Lets understand this by below step by step example. (Here I am not writing step to start visual studio and create a new project, I am pretty much sure you are aware of this now.)

Before going further let me tell you want we are going to do  here. We will have a input result (which will be a text file) and then sort it and save in another file.

Step 1:-I renamed package to SortPackage if you want you can rename your package as well. Now drag drop a Data Flow task as shown below and double click DATA flow task

Step 2:- When you click it you will get a data flow screen where you can drag drop FLAT file source. You can choose source assistance as well. Now configure this flat file source. Means give the path of the file which you want to have as a input source. I am taking a text file which contain fruits name in different order. as shown in below figure

Right click flat file source click on EDIT option and follow the screens

Step 3:- Now once the file is configure. We have to drag drop SORT control from SSIS tool box as shown in below figure.

I also added the output of flat file source to sort control. As shown in above figure. Now configure it. Click on Sort control and you will get following screen. As show in below screen you can sort the data on any column and in any direction like Ascending or descending.

Right there is only one input column which is name so we are sorting name in Ascending order as shown below.

Step 4:- Now once this configuration is done we will save the data in new file with new name which will be sortedFruits. Now to achieve this drag drop the destination control. So I took same float file destination as shown in below figure

Step 5:- Now configure this file destination. Which means where we need to save this file and what are the columns which we required. so In current case there is only one column which is Name (Fruit name) and I am saving this file at same place with sortFruits name. so lets configure it by clicking right click on flat file destination and click on edit button

Step 6:- Once this is configured we need to run this package by pressing F5.When you run hit F5 and everything going right then in execution screen at each step you will find green right check image as shown in below screen

Step 7: Now to cross check we will first see whether that file is created or not. If created then whether we have sorted data or not. So lets open the flat files.

So, if you see at provided destination location a file is created and the data inside this file is sorted file.

I hope you like this first transformation control. till then Enjoy!!!

Thanks !!

How to deploy SSIS Package ? Step by Step SSIS TIP #114

Dear Friends,
In last post we have successfully created our fist basic package. So, Now the next thing is how to deploy this package.

We have created this package for someone else or our client so we need to run this package on his /her machine.

For this we need to know how to deploy. Lets start this step by step 

Step 1:- Open the existing solution and right click on the solution you will get following options as shown in figure. You need to click on “Convert to Package Deployment Model”   as highlighted below

Step 2:- Once you click it you might get popup for confirmation just click OK.

Step 3: Now click on Properties you will get following screen in which you need to select the deployment option. And need to select true value for CreateDeploymentUtility as highlighted below in figure. Once You make this option true  press OK or Apply Button.

 

Step 4:- Once you done with this again right click on the solution and again click on Covert to Package deployment model.  Now this time you will get Wizard screen as shown below. Click on Next button

Step 5:- You will get below screen which is package selection screen. (Suppose you have multiple packages in a solution so for which package you want to create deployment you need to check / Uncheck according to your need.) Once you selected the Package click on Next button.

Step 6:- When you click next button you will get next option which is specific project properties as shown below in screen. In this we have an important option which is Protection level. It is use to set the level of showing sensitive data in package. for example a package may contain sql server connection string in which we have username and password and username and password are very important and sensitive information. Here ,with protection level we have option to encrypt this sensitive data or make package password protected. This will be an interesting topic which we will discuss separately in near future in separate post. for current time being just leave the default option as is and click on next button.

Step 7:- When you click on next button you will get following screen. This is the screen where you can call another package which this deployment. We will discuss it later for current deployment process we don’t want to call any other package.  Just click on next button.

Step 8:- When you click on next button you will get following screen which says about configurations. We can create a configuration file which is just a simple XML file. If you are a .NET developer just assume it web.config file where we can keep connection string or other configurable item.

Step 9:- We can create parameters which can be use to pass the values in packages. In current solution we have not configured even parameters so don’t think to much about this currently. We will discuss it separately in coming post.

Step 10:- Now directly jump to Perform Conversion and skip review step. and click next you will get following screen of popup. Press OK and then try to rebuild the solution.

Step 11:- We did  a build/rebuild to cross check package is correct. Now open the deployment folder in bin folder (You can find the address in step 3’s screen) . When you open the folder you will get two files one is Your package file with DTSX extension and another one which is called manifest file as shown in the figure below. Below ExportSQLToFlatFile is our manifest file  and Package is our actual DTSX package file. (if we have config file then you will find config file as well)

Step 12:- Now, we successfully completed our first part of deployment which is basically creating a package deployment file which is a manifest file. We can copy these files on any server where we need to deploy the package. When you click on Manifest file which is ExportSQLToFlatFile you will get following screen

Step 13: Click on Next button when you get above screen you will get following screen which shows 2 options of package deployment

1) File System deployment 2)  SQL Server deployment

Now for current demo we are using file system deployment and clicking next button.

Step 14:- When we click next button we get the screen which ask for folder where package will be deploy by default it is SQL SERVER’s DTS package folder so let it be currently and click Next button

Step 15:- After clicking next button , we will get following screen. Which is a confirmation screen for deployment.

Step 16:- Now the last step click the finish button and we are good to go.

So all the above steps are for creating a deployment for package and then deploy in SQL SERVER. Now , I am sure your next question will be what now ?

So, now we call this Package in SQL SERVER Job and configure job which execute this package time to time.

We, will discuss it more in detail coming post.

I hope you will like this post. please do post your inputs.

Thanks
