JDBC-ODBC Bridge Connector for PowerShell

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

JDBC-ODBC 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.

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

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 your Java application JDBC driver

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

  1. Visit Maven Repository portal, which is a central location for downloading Java libraries.
  2. Download your Java application JDBC driver matching your running instance version and save it locally, e.g. to D:\Drivers\JDBC\app-jdbc.jar.
  3. Done! That was easy, wasn't it? Let's proceed to the next step.
It is recommended to use JDBC driver compiled for Java 8, if possible.

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

Step-by-step instructions

To get data from JDBC-ODBC Bridge using PowerShell we first need to create a DSN (Data Source) which will access data from JDBC-ODBC Bridge. We will later be able to read data using PowerShell. 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

    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:

    JdbcOdbcBridgeDSN
    jdbc:exampleApp://app-service-host-name.com:1234
    com.provider.exampleApp.jdbc.AppDriver
    D:\Drivers\JDBC\app-jdbc.jar
    admin
    *************
    [{"Name":"AppParameter","Value":"12345"}]
    JDBC-ODBC Bridge driver data source settings
    ZappySys JDBC Bridge Driver allows you to connect to any Java application that supports JDBC.
  5. You should see a message saying that connection test is successful:

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

    JdbcOdbcBridgeDSN
    SELECT * FROM orders
    JDBC ODBC Bridge data source preview
    SELECT * FROM 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 JDBC-ODBC Bridge data in PowerShell

Sometimes, you need to quickly access and work with your JDBC-ODBC Bridge 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 JDBC-ODBC Bridge 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=JdbcOdbcBridgeDSN"
    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=JdbcOdbcBridgeDSN"
    $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 JDBC-ODBC Bridge fields
        $line = $format -f ($row["CustomerId"], $row["CompanyName"], $row["Country"], $row["Phone"])
        Write-Host $line
    }
    
    Access specific JDBC-ODBC Bridge 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 JDBC-ODBC Bridge.
  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=JdbcOdbcBridgeDSN"
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=JdbcOdbcBridgeDSN"
$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 - JDBC-ODBC Bridge
    JDBC-ODBC 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.
    JdbcOdbcBridgeDSN
    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.

Write JDBC-ODBC Bridge 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=JdbcOdbcBridgeDSN"
$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.
