Power BI Jdbc Connector

In this article you will learn, how to integrate Jdbc data to Power BI without coding in few clicks (Live / Bi-directional connection to Jdbc). Jdbc Bridge driver can be used to consume data from any JDBC Driver in non JAVA apps (i.e. Excel, Power BI, C#). Many apps written in C++ or .net (e.g. Excel, Power BI, Informatica) which don’t have direct support for using JAVA based JDBC driver technology.

Using Jdbc API Connector you will be able to connect, read and write data from within Power BI. Let's take a look at the steps below to see how exactly to accomplish that.

  • Using Jdbc Connection in Power BI

Create ODBC Data Source (DSN) based on ZappySys Jdbc Driver

To get data from Jdbc using Power BI we first need to create a DSN - Data Source - which will access data from Jdbc, which later will be able to get using Power BI. Perform these steps:

  1. Install ZappySys ODBC PowerPack.

  2. Open ODBC Data Sources (x64):
    Open ODBC Data Source

  3. Create a User Data Source (User DSN) based on ZappySys Jdbc Bridge Driver:

    Create new JDBC Bridge Driver

    You should create System DSN if client application is launched under Windows System Account, e.g. as a Windows Service.
    Launch ODBC Data Sources 32-bit version in case your client application is a 32-bit (x86) application (required only for System DSN).
  4. Now, we need Jdbc Bridge Connection. Lets create it. When you see DSN Config Editor with zappysys logo first thing you need to do is change default DSN Name at the top and Configure JDBC Bridge Driver. Enter Credentials (In this Example We have used PostgreSQL Credentials) and then Click on Test Connection to verify your credentials.

    Note : Enter suitable JDBC Driver Credentials, You can read data from any JDBC Driver
    ODBC Jdbc Bridge Driver - Create Connection

  5. This example shows how to write simple SOQL query (Jdbc Bridge Object Query Language). It uses WHERE clause. For more SOQL Queries click here.
    SOQL is similar to database SQL query language but much simpler and many features you use in database query may not be supported in SOQL (Such as JOIN clause not supported). But you can use following Queries for Insert, Update, Delete and Upsert(Update or Insert record if not found).

    SELECT orderid, customerid, orderdate, orderamount FROM "public"."zappysys"
    ZappySys ODBC Driver - Select Table and Preview Data
  6. Click OK to finish creating the data source

Read data in Power BI from the DSN

  1. Once you open Power BI Desktop click Get Data to get data from ODBC:
    Power Bi Get Data

  2. A window opens, and then search for "odbc" to get data from ODBC data source:
    Power Bi ODBC Get Data

  3. Another window opens and asks to select a Data Source we already created. Choose JdbcDSN and continue:

    JdbcDSN
    Power Bi Select ZappySys Driver DSN

  4. Most likely, you will be asked to authenticate to a newly created DSN. Just select Windows authentication option together with Use my current credentials option:

    JdbcDSN
    Power Bi DSN Authenticaation

  5. Finally, you will be asked to select a table or view to get data from. Select one and load the data!
    Power Bi Load DSN Table Data

  6. Finally, use data extracted from Jdbc API in Power BI reports:
    Power Bi Extracted DSN Table Data

Create Custom Store Procedure in ZappySys Driver

You can create procedures to encapsulate custom logic and then only pass handful parameters rather than long SQL to execute your API call.

Steps to create Custom Store Procedure in ZappySys Driver. You can insert Placeholders anywhere inside Procedure Body. Read more about placeholders here

  1. Go to Custom Objects Tab and Click on Add button and Select Add Procedure:
    ZappySys Driver - Add Store Procedure

  2. Enter the desired Procedure name and click on OK:
    ZappySys Driver - Add Store Procedure Name

  3. Select the created Store Procedure and write the your desired store procedure and Save it and it will create the custom store procedure in the ZappySys Driver:
    Here is an example stored procedure for ZappySys Driver. You can insert Placeholders anywhere inside Procedure Body. Read more about placeholders here

    CREATE PROCEDURE [usp_get_orders]
    @fromdate = '<<yyyy-MM-dd,FUN_TODAY>>'
    AS
    SELECT * FROM Orders where OrderDate >= '<@fromdate>'

    ZappySys Driver - Create Custom Store Procedure

  4. That's it now go to Preview Tab and Execute your Store Procedure using Exec Command. In this example it will extract the orders from the date 1996-01-01:

    Exec usp_get_orders '1996-01-01'

    ZappySys Driver - Execute Custom Store Procedure

Create Custom Virtual Table in ZappySys Driver

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 URLs with slight variations you can create virtual tables with just URL as Parameter setting.

  1. Go to Custom Objects Tab and Click on Add button and Select Add Table:
    ZappySys Driver - Add Table

  2. Enter the desired Table name and click on OK:
    ZappySys Driver - Add Table Name

  3. And it will open the New Query Window Click on Cancel to close that window and go to Custom Objects Tab.

  4. Select the created table, Select Text Type AS SQL and write the your desired SQL Query and Save it and it will create the custom table in the ZappySys Driver:
    Here is an example SQL query for ZappySys Driver. You can insert Placeholders also. Read more about placeholders here

    SELECT
    "ShipCountry",
    "OrderID",
    "CustomerID",
    "EmployeeID",
    "OrderDate",
    "RequiredDate",
    "ShippedDate",
    "ShipVia",
    "Freight",
    "ShipName",
    "ShipAddress",
    "ShipCity",
    "ShipRegion",
    "ShipPostalCode"
    FROM "Orders"
    Where "ShipCountry"='USA'

    ZappySys Driver - Create Custom Table

  5. That's it now go to Preview Tab and Execute your custom virtual table query. In this example it will extract the orders for the USA Shipping Country only:

    SELECT * FROM "vt__usa_orders_only"

    ZappySys Driver - Execute Custom Virtual Table Query

Import Jdbc data into Power BI from SQL Query

If you wish to import Jdbc data from SQL query rather than selecting table name then you can use advanced options during import steps (as below). After selecting DSN you can click on advanced options to see SQL Query editor.

Edit Query / Using Parameters in Power BI (Dynamic Query)

In the real world, many values of your REST / SOAP API call may be coming from Parameters. If that's the case for you can try to edit script manually as below. In below example its calling SQL Query with POST method and passing some parameters. Notice below where paraAPIKey is Power BI Parameter (string type). You can use parameters anywhere in your script just like the normal variable.

Import REST API in Power BI - Using parameters in SQL Query (Edit code - Advanced Mode)

 

let
    vKey=paraAPIKey,
    Source = Odbc.Query(
    "dsn=ZS-OData Customers", 
    "SELECT * FROM $ WITH (SRC='http://httpbin.org/post'," 
    & "METHOD='POST'," 
    & "HEADER='Content-Type:application/json'," 
    & "BODY=@'{""CallerId"":1111, ""ApiKey"":""" & vKey & """}')")
in
Source

Edit Query Settings after Import

There will be a time you need to change initial Query after dataset import in Power BI. Not to worry, just follow these steps to edit your SQL.

Using DirectQuery Option rather than Import

So far we have seen how to Import REST API data into Power BI but what if you have too much data and you dont want to import but link it. Power BI Offers very useful feature for this scenario. Its called DirectQuery Option. In this section we will explore how to use DirectQuery along with ZappySys Drivers. Out of the box ZappySys Drivers wont work in ODBC Connection Mode so you have to use SQL Server Connection rather than ODBC if you wish to use Live data using DirectQuery option. See below step by step instructions to enable DirectQuery mode in Power BI for REST API data. Basically we will use ZappySys Data Gateway its part of ODBC PowerPack. We will then use Linked Server in SQL Server to Link API Service and then we will issue OPENROWSET queries from Power BI to SQL Server and it will then call REST API via ZappySys Data Gateway.

Step-By-Step

  1. First read this article carefully, How to query Jdbc API in SQL Server.
  2. Once linked server is configured we are ready to issue API query in Power BI.
  3. Click Get Data in Power BI, select SQL Server Database
  4. Enter your server name and any database name
  5. Select Mode as DirectQuery
  6. Click on Advanced and enter query like below (we are assuming you have created JSON Data Source in Data Gateway and defined linked server (Change name below).
    Select * from OPENQUERY(JDBC_LINKED_SERVER,'SELECT * FROM Customers')
    Select * from OPENQUERY(
    JDBC_LINKED_SERVER,
    'SELECT * FROM Customers'
    )
    DirectQuery option for Power BI (Read REST API Data Example using SQL Server Linked Server and ZappySys Data Gateway)


    DirectQuery option for Power BI (Read REST API Data Example using SQL Server Linked Server and ZappySys Data Gateway)

  7. Click OK and Load data ... That's it. Now your Jdbc API data is linked rather than imported.

Working with Gateways in Power BI (Schedule Import)

If the data needs to be updated, it is necessary to create a gateway on-premises. In this new section, we will install a Power BI Gateway and in the next section schedule it to update the REST API information.
  1. In the last section, we Published the report. Power BI may ask you to SIGN IN.
    Sign in Power BI

    Sign in Power BI

  2. Select the Workspace and select Datasets
    Go do workspace and select dataset

    Go to workspace and dataset

  3. Right-click the report and select Settings.
    Define settings for Power BI report

    Specify settings for the report

  4. The system will ask for a Gateway. Stay here.
    add power bi gateway

    Add Power BI Gateway

  5. Use the following link to install a Data Gateway:
    https://docs.microsoft.com/en-us/power-bi/service-gateway-onprem
  6. Run the installer and press Next
    Initial gateway window for installation

    Gateway installer

  7. Select the option On-premises data gateway (recommended). This option allows access to multiple users and can be used by more applications than Power BI.
    Choose Power BI gateway

    Choose Power BI option

  8. The installer will show a warning message.
    Warning message gateway installation

    Warning message during installation

  9. Select the path to install and check the I accept the terms.
    accept terms

    Accept terms

  10. Specify the email address to use the gateway.
    Register email in gateway installation

    Register email address

  11. After entering the email, write the gateway name and a recovery key. Make sure to confirm the recovery key.
    Specify name and recovery key

    Enter recovery key

Manage gateways and configure the schedule

Once that the gateway is installed we will configure it and add the connection strings.
  1. The next step is to go to manage gateway
    Power BI - Manage Gateway Setting

    Power BI - Manage Gateway Setting

  2. In order to get the connection string, we will need the connection string of the ZappySys JSON Driver. In the first section of this post, we explained how to configure it. Press Copy Connection String
    ZappySys connection properties

    Connection properties

  3. Once that the data is copied, add a New data Source. In Data Source Name, enter the Data Source Name of the ZappySys JSON driver in step 13 and in Data Source Type, select ODBC. In connection string copy and paste from the clipboard of the step 13 and press Add.
