Azure Blob XML File ODBC Driver Powering this integration

High performance
Bidirectional
Low-code / No-code
Easy to use

Built on the ZappySys Azure Blob XML Driver, the Azure Blob XML File ODBC Driver is a high-performance, low-code / no-code solution. It enables you to connect to Azure Blob XML File data without any coding right in your SQL Server, or any ODBC/JDBC application. Part of the ODBC PowerPack.

Create data source in ZappySys Data Gateway

In this section we will create a data source for Azure Blob XML File in the Data Gateway. Let's follow these steps to accomplish that:

Download and install ODBC PowerPack (if you haven't already).
Search for gateway in the Windows Start Menu and open ZappySys Data Gateway Configuration:
Go to the Users tab and follow these steps to add a Data Gateway user:
- Click the Add button
- In the Login field enter a username, e.g., john
- Then enter a Password
- Check the Is Administrator checkbox
- Click OK to save
Now we are ready to add a data source:
- Click the Add button
- Give the Data source a name (have it handy for later)
- Then select Native - ZappySys Azure Blob XML Driver
- Finally, click OK
AzureBlobXmlFileDSN

ZappySys Azure Blob XML Driver
Create and configure a connection for the Azure Blob storage account.
You can use select your desired single file by clicking [...] path button.

mybucket/dbo.tblNames.xml

dbo.tblNames.xml

----------OR----------
You can also read the multiple files stored in Azure Blob Storage using wildcard pattern supported e.g. dbo.tblNames*.xml.
```
Note: If you want to operation with multiple files then use wild card pattern as below 
(when you use wild card pattern in source path then system will treat target path as folder regardless you end with slash)

mybucket/dbo.tblNames.xml (will read only single .XML file)
mybucket/dbo.tbl*.xml (all files starting with file name)
mybucket/*.xml (all files with .xml Extension and located under folder subfolder)
```
mybucket/dbo.tblNames*.xml

----------OR----------
You can also read the zip and gzip compressed files also without extracting it in using Azure Blob XML Source File Task.

mybucket/dbo.tblNames*.gz
Now select/enter Path expression in Path textbox to extract only specific part of XML string as below ($.value[*] will get content of value attribute from XML document. Value attribute is array of XML documents so we have to use [*] to indicate we want all records of that array)

NOTE: Here, We are using our desired filter, but you need to select your desired filter based on your requirement.
Go to Preview Tab.
Navigate to the Preview Tab and let's explore the different modes available to access the data.
1. --- Using Direct Query ---
  Click on Preview Tab, Select Table from Tables Dropdown and select [value] and click Preview.
2. --- Using Stored Procedure ---
  
  Note : For this you have to Save ODBC Driver configuration and then again reopen to configure same driver. For more information click here.
  Click on the Custom Objects Tab, Click on Add button and select Add Procedure and Enter an appropriate name and Click on OK button to create.
  1. --- Without Parameters ---
    Now Stored Procedure can be created with or without parameters (see example below). If you use parameters then Set default value otherwise it may fail to compilation)
  2. --- With Parameters ---
    
    Note : Here you can use Placeholder with Paramters in Stored Procedure. Example : SELECT * FROM $ WHERE OrderID = '<@OrderID, FUN_TRIM>' or CustId = '<@CustId>' and Total >= '<@Total>'
3. --- Using Virtual Table ---
  
  Note : For this you have to Save ODBC Driver configuration and then again reopen to configure same driver. For more information click here.
  
  ZappySys APi Drivers support flexible Query language so you can override Default Properties you configured on Data Source such as URL, Body. This way you don't have to create multiple Data Sources if you like to read data from multiple EndPoints. However not every application support supplying custom SQL to driver so you can only select Table from list returned from driver.
  
  Many applications like MS Access, Informatica Designer wont give you option to specify custom SQL when you import Objects. In such case Virtual Table is very useful. You can create many Virtual Tables on the same Data Source (e.g. If you have 50 Buckets with slight variations you can create virtual tables with just URL as Parameter setting).
```
vt__Customers
DataPath=mybucket_1/customers.xml

vt__Orders
DataPath=mybucket_2/orders.xml

vt__Products
DataPath=mybucket_3/products.xml
```
  1. Click on the Custom Objects Tab, Click on Add button and select Add Table and Enter an appropriate name and Click on OK button to create.
  2. Once you see Query Builder Window on screen Configure it.
  3. Click on Preview Tab, Select Virtual Table(prefix with vt__) from Tables Dropdown or write SQL query with Virtual Table name and click Preview.
Click OK to finish creating the data source
That's it; we are done. In a few clicks we configured the to Read the Azure Blob XML File data using ZappySys Azure Blob XML File Connector
Once done, go to the Network Settings tab and Add a firewall rule for inbound traffic:
- This will initially allow all inbound traffic.
- Click Edit IP filters to restrict access to specific IP addresses or ranges.
Crucial Step: After creating or modifying the data source, you must:
- Click the Save button to persist your changes.
- Hit Yes when prompted to restart the Data Gateway service.
This ensures all changes are properly applied:

Skipping this step may cause the new settings to fail, preventing you from connecting to the data source.

Read Azure Blob XML File data in Talend Studio

To read Azure Blob XML File data in Talend Studio, we'll need to complete several steps. Let's get through them all right away!

This article is compatible with Talend Open Studio (a free version, currently retired by Qlik). If you don't have it, you can still purchase a shareware version of Talend Studio from Qlik.

Create connection for input

First of all, open Talend Studio
Create a new connection:
Select Microsoft SQL Server connection:
Name your connection:
Fill-in connection parameters and then click Test connection:

AzureBlobXmlFileDSN
If the List of modules not installed for this operation window shows up, then download and install all of them:
Review and accept all additional module license agreements during the process
Finally, you should see a successful connection test result at the end:

Add input

Once we have a connection to ZappySys Data Gateway created, we can proceed by creating a job:
Simply drag and drop ZappySys Data Gateway connection onto the job:
Then create an input based on ZappySys Data Gateway connection:
Continue by configuring a SQL query and click Guess schema button:
Finish by configuring the schema, for example:

Add output

We are ready to add an output. From Palette drag and drop a tFileOutputDelimited output and connect it to the input:

Connecting tFileOutputDelimited output in Talend Studio

Run the job

Finally, run the job and integrate your Azure Blob XML File data:

Conclusion

In this article we showed you how to connect to Azure Blob XML File in Talend Studio and integrate data without writing complex code — all of this was powered by Azure Blob XML File ODBC Driver.
