Export Data from SQL Server to Flat File in Informatica

Before we start configuring the Informatica to Export Data from SQL Server to Text File (or Flat File). First, connect to Informatica repository service by providing the Informatica Admin Console credential.

TIP: Here you have to provide the Admin Username and password that you specified while installing the Informatica Server.

Step 1: Create a Source Definition to export data from SQL to Flat File in Informatica

Once you connected successfully, Please navigate to Source Analyzer to define your Sources. As we said before, we are using Employee table present in the SQL Server database as our source definitions. So, go to the Source menu and select the Import from Database.. option as shown below.

Please select the ODBC connection that will connect the Informatica with the SQL Tutorial Database. In order to create a new one, please refer to the Informatica ODBC Connection article.

From the below screenshot you can observe that we are selecting the Employee table from our SQL Tutorial database.

Step 2: Create Target Definition to move data from SQL to Text File in Informatica

Please navigate to Target Designer to define the Target. In this example, our task is to create a Text File target. So, go to the Targets menu and select the Create option as shown below.

Once you select the Create option, a new window called Create Target table will be displayed as shown below. Please provide a unique name for the target table, and select the database type as Flat File. 

Once you are done, Please click on the Create button to create a new empty table in our PowerCenter Target Designer.

In order to add new columns, we have to edit the table definition. This can be done by Right click on the table, and select the Edit.. option from the context menu. Once you select the Edit.. option, a new window called Edit tables will be opened as shown below.

By default Flat File columns will be separated by the Comma Delimiter. But, you can control the same by clicking the Advanced button

Export Data from SQL Server to Flat File in Informatica 8

Here, you can change the Column Delimiter, and you can add Single Quoted, or double quotes each column value.

Next, go to the Columns Tab to add new columns. Please select the first button (before scissors symbol) as shown below. This will open the empty row to add Column Name, Data Type, Precision (if required), Scale (if required).

If it is primary key then change the Key type to primary and check to mark the Not Null option (if your column doesn’t allow null values)

Export Data from SQL Server to Flat File in Informatica 10

From the below screenshot you can observe that, we added four columns.

Step 3: Create Mapping to export data from SQL to Flat File in Informatica

To create a new mapping, Please navigate to Mappings menu in Menu Bar, and select the Create.. option.

Export Data from SQL Server to Flat File in Informatica 14

This will open the Mapping Name window to write a unique name for this mapping. Let me write m_export_SQL_to_text and click OK button.

TIP : Please refer Informatica Mapping article to understand the procedure to create Mapping

Export Data from SQL Server to Flat File in Informatica 15

Drag and drop the Employe source definitions from Sources folder to the mapping designer. Once you drag the source, Power Center designer will automatically create the source qualifier for you. I suggest you to refer the Source Qualifier Transformation article

Export Data from SQL Server to Flat File in Informatica 16

Next, Drag and drop the target definition from Targets folder to the mapping designer. Next, connect the source qualifier with the target definition. Please use the Autolink.. option to connect them.

Before we close the Mapping, Let us Save, and Validate the mapping by going to Mapping Menu bar, and select the Validate option.

Step 4: Create a Workflow to move data from SQL Server to Text File in Informatica

After we finish creating the Mapping, we have to create the workflow for it. Power Center Workflow manager provides two approaches to create a workflow.

  • Create Workflow Manually
  • Create Workflow using Wizard

In this Informatica Export Data from SQL Server to Flat File example, we will create the Workflow manually. To do so, Please navigate to Workflows Menu and select the Create option.

Export Data from SQL Server to Flat File in Informatica 18

This will open Create Workflow window as shown below. Please provide the unique name (wf_export_SQL_to_text) and leave the default settings.

Export Data from SQL Server to Flat File in Informatica 19

Once we created the workflow, our next step is to create a session task for our mapping.

Step 4(a): Create Session to move data from SQL to Text File

There are two types of sessions in informatica:

  • Non-Reusable Session in Informatica
  • Reusable Session in Informatica

For this Informatica Export Data from SQL Server to Flat File example, we created a Non-reusable Session. In order to create Non-reusable Session, Please navigate to Tasks Menu and select the Create option as shown below.

Export Data from SQL Server to Flat File in Informatica 20

Please provide a unique name for this session. Here, we are naming it as s_export_sql_to_text

Export Data from SQL Server to Flat File in Informatica 21

Once you click on the Create button, a new window called Mappings will be opened. Here you have to select the mapping that you want to associate with this session i.e., m_export_sql_to_text.

Export Data from SQL Server to Flat File in Informatica 22

Please link the Start Task, and the Session Task.

Export Data from SQL Server to Flat File in Informatica 23

Double click on the Session task will open the Edit Tasks window. Within Properties Tab, we have configure $Source connection value. This property will store the relational source information in $Source variable.

Export Data from SQL Server to Flat File in Informatica 24

So, click on the Arrow we marked above, and select the SQL Tutorial as the source information.

Export Data from SQL Server to Flat File in Informatica 25

You can configure the Sessions Log properties, Error properties in Config Object

Export Data from SQL Server to Flat File in Informatica 26

Within the mappings tab, we have to configure the Source, and target Connections. First, let us configure the source connections by clicking on the SQ_Employe source present in the Sources folder.

With in the Connections, click on the Arrow button beside the Relational type, and Use Connection variable that we created in our previous step i.e., $Source

Export Data from SQL Server to Flat File in Informatica 27

Now, we have to configure the Target Connection. So, let us configure the target connection by clicking on the Employetable present in the Targets folder.

Export Data from SQL Server to Flat File in Informatica 28

If you requirement is Merging the data then use this Merge Type property. For now, we are leaving it to No Merge option. I suggest you to explore the remaining options.

Export Data from SQL Server to Flat File in Informatica 29

  • Append If Exists: data will be appended if the file already exits.
  • Output File Directly: Informatica will use the default directory but you can change the directory by giving full path.
  • Output filename: Please change the extension to txt

Export Data from SQL Server to Flat File in Informatica 30

Next, navigate to Workflows Menu and select the Validate option to validate the Workflow. Now, Let me start the Workflow by selecting the Start Workflow option in Workflows Menu.

Export Data from SQL Server to Flat File in Informatica 31

Once you select the Start Workflow option, Informatica PowerCenter Workflow monitor will be opened to monitor the workflow. From the below screenshot you can observe that, our workflow is executed without any errors.

Export Data from SQL Server to Flat File in Informatica 32

Let us open the default target location of the Informatica to check whether we successfully created a text file, and transfer the data from a source or not.

Export Data from SQL Server to Flat File in Informatica 33

You can see the data inside the employee table text file.

Export Data from SQL Server to Flat File in Informatica 34

Let me change the file location from Default Informatica destination to D folder, and also changing the name as employeetable. Next, Save and start the Workflow

Export Data from SQL Server to Flat File in Informatica 35

Now you can see the employeetable.txt in D drive
