Infor Data Lake Connector for PowerShell

Infor Data Lake Connector lets you connect to the Infor Data Lake within the Infor Data Fabric, allowing you to access and utilize your organization's comprehensive data assets.

In this article you will learn how to quickly and efficiently integrate Infor Data Lake data in PowerShell without coding. We will use high-performance Infor Data Lake Connector to easily connect to Infor Data Lake and then access the data inside PowerShell.

Let's follow the steps below to see how we can accomplish that!

Download Documentation

Prerequisites

Before we begin, make sure you meet the following prerequisite:

If you already have a JRE installed, you can try using it too. However, if you experience any issues, we recommend using one of the distributions mentioned above (you can install an additional JRE next to the existing one; just don't forget to configure the default Java in the Windows Environment Variables).

Download Infor Data Lake JDBC driver

To connect to Infor Data Lake in PowerShell, you will have to download JDBC driver for it, which we will use in later steps. Let's perform these little steps right away:

  1. Visit Infor Data Lake video tutorial or official website.
  2. Follow the instructions there, download the JDBC driver, and save it locally, e.g. to D:\Drivers\JDBC\infor-compass-jdbc.jar.
    It is recommended to use JDBC driver compiled for Java 8, if possible.
  3. Then download ION API file from Infor and place it in the same directory as the JDBC driver, e.g. D:\Drivers\JDBC\Infor Compass JDBC Driver.ionapi.
    Do not rename Infor Compass JDBC Driver.ionapi file as it will fail to load the driver. Also, JDBC driver and ION API file have to reside in the same folder for the driver to work.
  4. Done! That was easy, wasn't it? Let's proceed to the next step.

Create ODBC Data Source (DSN) based on ZappySys JDBC Bridge Driver

Step-by-step instructions

To get data from Infor Data Lake using PowerShell we first need to create a DSN (Data Source) which will access data from Infor Data Lake. We will later be able to read data using PowerShell. Perform these steps:

  1. Download and install 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

    ZappySys JDBC Bridge Driver
    Create new User DSN for ZappySys JDBC Bridge Driver
    • Create and use User DSN if the client application is run under a User Account. This is an ideal option in design-time, when developing a solution, e.g. in Visual Studio 2019. Use it for both type of applications - 64-bit and 32-bit.
    • Create and use System DSN if the client application is launched under a System Account, e.g. as a Windows Service. Usually, this is an ideal option to use in a production environment. Use ODBC Data Source Administrator (32-bit), instead of 64-bit version, if Windows Service is a 32-bit application.
  4. Now, we need to configure the JDBC connection in the new ODBC data source. Simply enter the Connection string, credentials, configure other settings, and then click Test Connection button to test the connection:

    InforDataLakeDSN
    jdbc:infordatalake://MY_DATALAKE_ID
    com.infor.idl.jdbc.Driver
    D:\Drivers\JDBC\infor-compass-jdbc.jar
    john.smith@my-company.com
    *********
    []
    JDBC-ODBC Bridge driver data source settings

    Use these values when setting parameters:

    • Connection string: jdbc:infordatalake://MY_DATALAKE_ID
    • Driver class: com.infor.idl.jdbc.Driver
    • JDBC driver file(s): D:\Drivers\JDBC\infor-compass-jdbc.jar
    • User name: john.smith@my-company.com
    • User password: *********
    • Connection parameters: []

  5. You should see a message saying that connection test is successful:

    ODBC connection test is successful

    Otherwise, if you are getting an error, check out our Community for troubleshooting tips.

  6. We are at the point where we can preview a SQL query. For more SQL query examples visit JDBC Bridge documentation:

    InforDataLakeDSN
    SELECT * FROM "default"."orders"
    JDBC ODBC Bridge data source preview
    SELECT * FROM "default"."orders"
    You can also click on the <Select Table> dropdown and select a table from the list.

    The ZappySys JDBC Bridge Driver acts as a transparent intermediary, passing SQL queries directly to the Trino JDBC driver, which then handles the query execution. This means the Bridge Driver simply relays the SQL query without altering it.

    Some JDBC drivers don't support INSERT/UPDATE/DELETE statements, so you may get an error saying "action is not supported" or a similar one. Please, be aware, this is not the limitation of ZappySys JDBC Bridge Driver, but is a limitation of the specific JDBC driver you are using.

  7. Click OK to finish creating the data source.

Read Infor Data Lake data in PowerShell

Sometimes, you need to quickly access and work with your Infor Data Lake data in PowerShell. Whether you need a quick data overview or the complete dataset, this article will guide you through the process. Here are some common scenarios:

Viewing data in a terminal
  • Quickly peek at Infor Data Lake data
  • Monitor data constantly in your console
Saving data to a file
  • Export data to a CSV file so that it can be sliced and diced in Excel
  • Export data to a JSON file so that it can ingested by other processes
  • Export data to an HTML file for user-friendly view and easy sharing
  • Create a schedule to make it an automatic process
Saving data to a database
  • Store data internally for analysis or for further ETL processes
  • Create a schedule to make it an automatic process
Sending data to another API
  • Integrate data with other systems via external APIs

In this article, we will delve deeper into how to quickly view the data in PowerShell terminal and how to save it to a file. But let's stop talking and get started!

Reading individual fields

  1. Open your favorite PowerShell IDE (we are using Visual Studio Code).
  2. Then simply follow these instructions:
    "DSN=InforDataLakeDSN"
    Read API data with PowerShell using ODBC DSN in Visual Code

    For your convenience, here is the whole PowerShell script:

    # Configure connection string and query
    $connectionString = "DSN=InforDataLakeDSN"
    $query = "SELECT * FROM Customers"
    
    # Instantiate OdbcDataAdapter and DataTable
    $adapter = New-Object System.Data.Odbc.OdbcDataAdapter($query, $connectionString)
    $table = New-Object System.Data.DataTable
    
    # Fill the table with data
    $adapter.Fill($table)
    
    # Since we know we will be reading just 4 columns, let's define format for those 4 columns, each separated by a tab
    $format = "{0}`t{1}`t{2}`t{3}"
    
    # Display data in the console
    foreach ($row in $table.Rows)
    {
        # Construct line based on the format and individual Infor Data Lake fields
        $line = $format -f ($row["CustomerId"], $row["CompanyName"], $row["Country"], $row["Phone"])
        Write-Host $line
    }
    
    Access specific Infor Data Lake table field using this code snippet:
    $field = $row["ColumnName"]
    You will find more info on how to manipulate DataTable.Rows property in Microsoft .NET reference.
    For demonstration purposes we are using sample tables which may not be available in Infor Data Lake.
  3. To read values in a console, save the script to a file and then execute this command inside PowerShell terminal: Read API data in PowerShell using ODBC DSN
    You can also use even a simpler command inside the terminal, e.g.:
    . 'C:\Users\john\Documents\dsn.ps1'

Retrieving all fields

However, there might be case, when you want to retrieve all columns of a query. Here is how you do it:

"DSN=InforDataLakeDSN"
Read all API columns from ODBC data source in PowerShell

Again, for your convenience, here is the whole PowerShell script:

# Configure connection string and query
$connectionString = "DSN=InforDataLakeDSN"
$query = "SELECT CustomerId, CompanyName, Country, Phone FROM Customers"

# Instantiate OdbcDataAdapter and DataTable
$adapter = New-Object System.Data.Odbc.OdbcDataAdapter($query, $connectionString)
$table = New-Object System.Data.DataTable

# Fill the table with data
$adapter.Fill($table)

# Display data in the console
foreach ($row in $table.Rows) {
    $line = ""
    foreach ($column in $table.Columns) {
        $value = $row[$column.ColumnName]

        # Let's handle NULL values
        if ($value -is [DBNull])
        {
            $value = "(NULL)"
        }
        $line += $value + "`t"
    }
    Write-Host $line
}
You can limit the numbers of lines to retrieve by using a LIMIT keyword in the query, e.g.:
SELECT * FROM Customers LIMIT 10

Using a full ODBC connection string

In the previous steps we used a very short format of ODBC connection string - a DSN. Yet sometimes you don't want a dependency on an ODBC data source (and an extra step). In those times, you can define a full connection string and skip creating an ODBC data source entirely. Let's see below how to accomplish that in the below steps:

  1. Open ODBC data source configuration and click Copy settings:
    ZappySys JDBC Bridge Driver - Infor Data Lake
    Infor Data Lake Connector lets you connect to the Infor Data Lake within the Infor Data Fabric, allowing you to access and utilize your organization's comprehensive data assets.
    InforDataLakeDSN
    Copy connection string for ODBC application
  2. The window opens, telling us the connection string was successfully copied to the clipboard: Successful connection string copying for ODBC application
  3. Then just paste the connection string into your script: Paste ODBC connection string in PowerShell to read API data
  4. You are good to go! The script will execute the same way as using a DSN.

Have in mind that a full connection string has length limitations.

Proceed to the next step to find out the details.

Limitations of using a full connection string

Despite using a full ODBC connection string may be very convenient it comes with a limitation: it's length is limited to 1024 symbols (or sometimes more). It usually happens when API provider generates a very long Refresh Token when OAuth is at play. If you are using such a long ODBC connection string, you may get this error:

"Connection string exceeds maximum allowed length of 1024"

But there is a solution to this by storing the full connection string in a file. Follow the steps below to achieve this:

  1. Open your ODBC data source.
  2. Click Copy settings button to copy a full connection string (see the previous section on how to accomplish that).
  3. Then create a new file, let's say, in C:\temp\odbc-connection-string.txt.
  4. Continue by pasting the copied connection string into a newly created file and save it.
  5. Finally, the last step! Just construct a shorter ODBC connection string using this format:
    DRIVER={ZappySys JDBC Bridge Driver};SettingsFile=C:\temp\odbc-connection-string.txt
  6. Our troubles are over! Now you should be able to use this connection string in PowerShell with no problems.
This feature requires ODBC PowerPack v1.9.0 or later.

Write Infor Data Lake data to a file in PowerShell

Save data to a CSV file

Export data to a CSV file so that it can be sliced and diced in Excel:

# Configure connection string and query
$connectionString = "DSN=InforDataLakeDSN"
$query = "SELECT * FROM Customers"

# Instantiate OdbcDataAdapter and DataTable
$adapter = New-Object System.Data.Odbc.OdbcDataAdapter($query, $connectionString)
$table = New-Object System.Data.DataTable

# Fill the table with data
$adapter.Fill($table)

# Export table data to a file
$table | ConvertTo-Csv -NoTypeInformation -Delimiter "`t" | Out-File "C:\Users\john\saved-data.csv" -Force

Save data to a JSON file

Export data to a JSON file so that it can ingested by other processes (use the above script, but change this part):

# Export table data to a file
$table | ConvertTo-Json | Out-File "C:\Users\john\saved-data.json" -Force

Save data to an HTML file

Export data to an HTML file for user-friendly view and easy sharing (use the above script, but change this part):

# Export table data to a file
$table | ConvertTo-Html | Out-File "C:\Users\john\saved-data.html" -Force
Check useful PowerShell cmdlets other than ConvertTo-Csv, ConvertTo-Json, and ConvertTo-Html for other data manipulation scenarios.

Conclusion

In this article we showed you how to connect to Infor Data Lake in PowerShell and integrate data without any coding, saving you time and effort. It's worth noting that ZappySys JDBC Bridge Driver allows you to connect not only to Infor Data Lake, but to any Java application that supports JDBC (just use a different JDBC driver and configure it appropriately).
