Export Netezza to CSV

Jump to


    Welcome to our comprehensive guide on exporting data from Netezza to CSV format, a process that unlocks the full potential of your data by facilitating its integration with a variety of third-party systems such as Informatica, custom ETL solutions, and JDBC/ODBC connectors. Converting your Netezza data into a CSV file not only simplifies the exploration and manipulation of data within spreadsheet applications but also provides flexibility with easy file compression and the creation of uncompressed flat files for further processing. In this guide, we will delve into what Netezza is, the step-by-step process of exporting data to a CSV file, the practical use cases for such exports, as well as exploring Sourcetableā€”an alternative method for exporting Netezza data. Additionally, we will address common questions about the export process to ensure a smooth and efficient experience for all users seeking to leverage their Netezza data to its fullest extent.

    What is Netezza?

    Netezza is an enterprise data warehouse that supports deep analytics, business intelligence, and AI/ML workloads. It is designed to cater to data engineers, data scientists, and data analysts, enabling them to run complex workloads efficiently without the need for additional ETL or data movement. As a cloud-native solution, Netezza provides flexibility in deployment across SaaS, hybrid, and on-premises environments and is fully managed for ease of use.

    With its foundation on massively parallel processing architecture, Netezza facilitates high-performance analytics and AI workloads, offering near real-time insights. It allows users to quickly create, train, and deploy machine learning models within the database, utilizing in-database analytics tailored for data scientists. Netezza supports all major programming languages, including Python, R, and Spark, making it a versatile tool for various data science applications.

    Netezza's elastic scaling capabilities enhance workload efficiency, cost predictability, and reduce overall costs, benefiting organizations with its AI-infused operations. The compatibility with open formats like Parquet and Iceberg, along with integration with data lakehouses, ensures secure data sharing and seamless collaboration. Additionally, Netezza is HIPAA-ready and available across multiple data centers in North America, Europe, and Asia Pacific, ensuring global availability and compliance with data governance standards.

    Exporting Data from Netezza to a CSV File

    Using External Tables

    Exporting data to a CSV file in Netezza is most efficiently done using external tables. This method allows for fast data export to a filesystem that is mounted on the Netezza host. When using external tables, data can also be exported to a local workstation. However, it is important to note that external tables cannot wrap every column in quotation marks by default. To achieve quoted columns, concatenation must be used within the external table definition. Utilizing a filesystem that is mounted locally to the Netezza host and employing concatenation for quoting will ensure a swift and effective CSV export.

    Using the nzsql Command Line Interface

    Another option to export data from Netezza to a CSV file is through the nzsql command line interface (CLI) using the -o flag. This method still enables the export of CSV data, but it is generally slower compared to using external tables. Despite the speed difference, it provides a straightforward approach for those familiar with command line operations.

    Sourcetable Integration

    Optimize Your Data Workflow with Sourcetable

    For those seeking to streamline their data management processes, Sourcetable offers a revolutionary approach that surpasses the traditional method of exporting data from Netezza to CSV before importing it into a spreadsheet. With Sourcetable, you can directly import your Netezza data into a dynamic spreadsheet environment, bypassing the cumbersome CSV export-import cycle. This direct sync ensures that your data is always up-to-date, providing a live and accurate reflection of your databases.

    Sourcetable's platform is designed to facilitate ease of use, allowing you to automatically pull in data from multiple sources, including Netezza, and interact with it through a familiar spreadsheet interface. This seamless integration is a boon for automation, as it eliminates the repetitive tasks associated with manual exports and imports. Moreover, Sourcetable's capabilities are a powerful asset for business intelligence, enabling you to query and analyze your data in real time, leading to more informed decision-making and strategic insights.

    Frequently Asked Questions

    How do you export data from Netezza to a CSV file?

    To export data from Netezza to a CSV file, you can use the nzsql command to create an external table that points to a filesystem mounted locally to the Netezza host. You would use the CREATE external TABLE statement along with the USING clause specifying a delimiter option, and then insert the data with AS SELECT * FROM your_table_name.

    What delimiter should be used when exporting data from Netezza to CSV?

    When exporting data from Netezza to CSV, you should use '' as the delimiter. This is specified in the USING clause of the CREATE external TABLE statement.

    How can you ensure that data values are wrapped in quotation marks when exporting to CSV from Netezza?

    To wrap data values in quotation marks when exporting to CSV from Netezza, you can explicitly concatenate each column with inverted commas in the SQL statement used for the data export.

    Can you export data from Netezza to CSV on a workstation via ODBC, JDBC, or OLE-DB?

    Yes, when connecting to Netezza via ODBC, JDBC, or OLE-DB, you can export data to your workstation by using CREATE external TABLE 'c:test_export.txt' in your nzsql command.

    Where is the CSV file saved when exporting data from Netezza to a local filesystem?

    When exporting data from Netezza to a CSV file on a local filesystem, the file is saved to the path specified in the CREATE external TABLE statement, such as '/tmp/test_export.txt' for Unix-like systems.


    Exporting data from Netezza to CSV is a streamlined process that can be accomplished through the use of external tables or the nzsql CLI interface. While external tables allow for efficient data transfer directly to a filesystem on the Netezza host or to a workstation via JDBC, ODBC, or OLE-DB, they do not support wrapping data in quotation marks by default. However, quotation marks can be manually added using SQL concatenation or by utilizing the nzsql CLI, albeit with slower performance. The delimiter used in the export must be specified as . Instead of navigating these steps to export to CSV, you can streamline your data import process by using Sourcetable to directly import data into a spreadsheet.
