JDBC-ODBC Bridge Connector for PowerShell
In this article you will learn how to integrate Using JDBC-ODBC Bridge Connector you will be able to connect, read, and write data from within PowerShell. Follow the steps below to see how we would accomplish that. The driver mentioned above is part of ODBC PowerPack which is a collection of high-performance Drivers for various API data source (i.e. REST API, JSON, XML, CSV, Amazon S3 and many more). Using familiar SQL query language you can make live connections and read/write data from API sources or JSON / XML / CSV Files inside SQL Server (T-SQL) or your favorite Reporting (i.e. Power BI, Tableau, Qlik, SSRS, MicroStrategy, Excel, MS Access), ETL Tools (i.e. Informatica, Talend, Pentaho, SSIS). You can also call our drivers from programming languages such as JAVA, C#, Python, PowerShell etc. If you are new to ODBC and ZappySys ODBC PowerPack then check the following links to get started. |

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:
-
Install ZappySys ODBC PowerPack.
-
Open ODBC Data Sources (x64):
-
Create a User Data Source (User DSN) based on ZappySys JDBC Bridge Driver
ZappySys JDBC Bridge DriverYou should create a System DSN (instead of a User DSN) if the client application is launched under a Windows System Account, e.g. as a Windows Service. If the client application is 32-bit (x86) running with a System DSN, use ODBC Data Sources (32-bit) instead of the 64-bit version. -
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 -
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" -
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
- 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
- Store data internally for analysis or for further ETL processes
- Create a schedule to make it an automatic process
- 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
- Open your favorite PowerShell IDE (we are using Visual Studio Code).
-
Then simply follow these instructions:
"DSN=JdbC-OdbcBridgeDSN"
For your convenience, here is the whole PowerShell script:
# Configure connection string and query $connectionString = "DSN=JdbC-OdbcBridgeDSN" $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 $line }
Access specific JDBC-ODBC Bridge table field using this code snippet:
You will find more info on how to manipulate$field = $row["ColumnName"]
DataTable.Rows
property in Microsoft .NET reference.For demonstration purposes we are using sample tables which may not be available in JDBC-ODBC Bridge. -
To read values in a console, save the script to a file and then execute this command inside PowerShell terminal:
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:
Again, for your convenience, here is the whole PowerShell script:
# Configure connection string and query
$connectionString = "DSN=JdbC-OdbcBridgeDSN"
$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
}
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:
-
Open ODBC data source configuration and click Copy settings:
ZappySys JDBC Bridge Driver - JDBC-ODBC BridgeJDBC-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.JdbC-OdbcBridgeDSN
- The window opens, telling us the connection string was successfully copied to the clipboard:
- Then just paste the connection string into your script:
- You are good to go! The script will execute the same way as using a DSN.
Have in mind that using a full connection string has length limitations.
Proceed to the next step to find out the details.
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=JdbC-OdbcBridgeDSN"
$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
ConvertTo-Csv
, ConvertTo-Json
, and ConvertTo-Html
for other data manipulation scenarios.
