Step-by-Step Guide to PostgreSQL ODBC Driver Configuration

Configuring ODBC Driver for PostgreSQL

The ODBC (Open Database Connectivity) driver for PostgreSQL allows applications to connect to a PostgreSQL database using ODBC-compliant interfaces. This article provides a step-by-step guide to installing, configuring, and using the PostgreSQL ODBC driver, with examples and detailed explanations.

What is an ODBC Driver for PostgreSQL?

The PostgreSQL ODBC driver, also known as psqlODBC, enables database connectivity by implementing the ODBC standard. It is essential for applications that rely on ODBC for database access, such as Microsoft Excel, Tableau, or custom applications.

Installing the PostgreSQL ODBC Driver

Step 1: Download the Driver

Download the latest ODBC driver for PostgreSQL from the psqlODBC website.

Step 2: Install the Driver

Windows: Use the .msi installer to install the driver.

Linux: Install using package managers:

sudo apt update
sudo apt install odbc-postgresql

Configuring the ODBC Driver

Step 1: Configure the ODBC Data Source

On Windows:

    1. Open ODBC Data Source Administrator.

    2. Click on Add and select the PostgreSQL ODBC driver.

    3. Provide the connection details (host, database name, user, password, port).

On Linux: Modify the odbc.ini and odbcinst.ini files.

Example: odbc.ini

Code:

[PostgreSQL]
Description = PostgreSQL ODBC Data Source
Driver = PostgreSQL
Server = localhost
Port = 5432
Database = mydb
UID = myuser
PWD = mypassword

Example: odbcinst.ini

Code:

[PostgreSQL]
Description = ODBC Driver for PostgreSQL
Driver = /usr/lib/x86_64-linux-gnu/odbc/psqlodbcw.so

Step 2: Test the Connection

Use the isql command-line tool to test the ODBC connection.

Code:

isql -v PostgreSQL

Explanation:

  • isql: A utility to verify ODBC data source connections.
  • PostgreSQL: The data source name defined in odbc.ini.

Example: Querying PostgreSQL Using ODBC

Python Example:

Code:

import pyodbc

# Define the connection string
connection_string = (
    "DRIVER={PostgreSQL};"
    "SERVER=localhost;"
    "PORT=5432;"
    "DATABASE=mydb;"
    "UID=myuser;"
    "PWD=mypassword;"
)

# Connect to the PostgreSQL database
conn = pyodbc.connect(connection_string)

# Execute a query
cursor = conn.cursor()
cursor.execute("SELECT * FROM my_table")

# Fetch results
for row in cursor.fetchall():
    print(row)

# Close the connection
conn.close()

Explanation:

  • pyodbc: A Python library to interact with ODBC data sources.
  • DRIVER={PostgreSQL}: Specifies the ODBC driver.
  • execute(«SELECT * FROM my_table»): Executes a SQL query on the PostgreSQL database.

Advantages of Using ODBC with PostgreSQL

  • Cross-Platform Compatibility: ODBC supports multiple platforms and programming languages.
  • Standardized Interface: Provides a uniform interface for database connectivity.
  • Application Integration: Easily integrates PostgreSQL with tools like Excel, Tableau, and custom applications.

Best Practices:

  • Secure Connections: Use SSL/TLS for secure ODBC connections.
  • Error Logging: Enable detailed error logging in the ODBC configuration.
  • Driver Updates: Regularly update the ODBC driver to the latest version for improved performance and compatibility.

Introduction

This article explains how to connect to PostgreSQL with the official PostgreSQL ODBC driver psqlodbc, when using Windows 10.

It covers the following topics:

  1. How to connect to postrgreSQL (with code samples).
  2. How to setup ODBC:
    • Configure ODBC using the ODBC Data Source Administrator:

      We recommend using system DSNs (available to all users).

Connect to PostgreSQL Server [top]

We strongly recommend using connection objects to connect to databases, and this is what we demonstrate in the code samples.

Follow these steps to connect:

  1. Create a new channel to try out the code:
    • Create a channel like this:
      • Name: DB PostgreSQL Connection (or similar)
      • Source: From Translator
      • Destination: To Channel
    • Alternatively use an existing channel:

      Your channel will need a From/To Translator or a Filter component.

  2. Connect to a database using ODBC:
    • Paste this code into the Translator:

      If your script uses connection object methods conn:query{} or conn:execute{}to connect to a remote PostgreSQL database, the location of the remote host is specified as part of the name parameter in the db.connect{ } command. If you use conn:merge{} to connect the remote host is specified as part of the name parameter in the conn:merge{} command itself.

      function main()
      local conn = db.connect{   
      api=db.POSTGRES,
      name='your_odbc_server_name',
      user='your_login',
      password='secret',
      use_unicode = true,
      live = true
   }

   conn:execute{sql='SELECT * FROM <your table>', live=true}
end
    • The name is the name of an ODBC source that you create using the ODBC Administrator.
  3. Adapt the code to your requirements.

Setup ODBC [top]

Note: Iguana may not always support the very latest version of the PostgreSQL ODBC drivers, so you can simply download an earlier version if necessary. This is particularly true if you are not able to use the the latest version of Iguana.

If you need to know which versions of PostgreSQL are supported by the version of Iguana you are using please contact us at support@interfaceware.com.

To set up a new ODBC data source for PostgreSQL:

  1. Install the latest PostgreSQL ODBC drivers:
    • Download the latest 64 bit driver installer (zipped msi file) from the psqlodbc download site.
    • Unzip the file.
    • Run the msi installer and accept the defaults.
  2. Open the 64 bit ODBC Administrator:

    Windows 10 (64 bit version) supports 32 and 64 bit ODBC sources — always use the 64 bit ODBC Administrator.

  3. Open the System DSN tab and click Add:
    odbc system dsn

  4. Choose the latest PostgreSQL ODBC driver and click Finish:
    choose postresql odbc driver

    Картинка с сайта: help.interfaceware.com

  5. Enter the ODBC credentials:
    • Use any Data Source and Description you prefer.
    • Optional: Choose your default Database.
    • Enter the Network Name of the PostgreSQL Server in the Server field:
      Note: If you are unsure of the name ask your DBA (database administrator).
    • Optional: Enter the Port number (default = 5432)
    • Enter the User name and Password:
      Note: If you are unsure of these ask your DBA (database administrator).

  6. Test the data source connection:
  7. If the connection does not work speak to your DBA (database administrator) about how to login to the database (user authentication).

Troubleshooting [top]

  • Problems with connection settings:

    Speak to your DBA (database administrator) for general connection issues like: User name and password, Database Server network name etc.

  • Iguana may not always support the very latest version of the psqlodbc ODBC drivers:

    Please contact us at support@interfaceware.com if you need to know the latest supported version of the psqlodbc ODBC drivers.

  • Incorrect port number:

    SQL Server defaults to port 5432, but a different port can be used. Speak to your database administrator (DBA) or network administrator.

  • Using integrated security:

    Using integrated security is the usual way to connect to a Microsoft SQL Server database. If this does not work speak to your DBA (database administrator).

If you need more help please contact us at support@interfaceware.com.

More Information [top]

  • Using Database Connection Objects
  • Forum thread on Windows ODBC
  • Using Integrated Authentication, Microsoft SQL Server documentation (kerberos etc)
