How To Export Data from Netezza to CSV

Introduction

Exporting data from Netezza to a CSV file is a straightforward process, critical for data analysis and reporting. This guide will walk you through each step, ensuring a smooth and efficient export.

Whether you are handling large datasets or just a few records, knowing how to efficiently export your data is essential. We'll cover the necessary SQL commands and tools required to complete the task.

Additionally, we will explore how Sourcetable lets you analyze your exported data with AI in a simple-to-use spreadsheet.

How to Export Your Data to CSV Format from Netezza

Using External Tables

To export data from Netezza to CSV, it is recommended to use the external tables functionality. This method is efficient and involves creating an external table on a filesystem that is locally mounted to the Netezza host.

To create an external table, utilize the CREATE EXTERNAL TABLE command. The table can be created using drivers such as JDBC, ODBC, or OLE-DB. For example, use the following command to export data:

CREATE external TABLE 'c:/test_export.txt' USING (delimiter ',') AS SELECT * FROM test_export

Wrapping Columns in Quotation Marks

Although the external table functionality does not inherently provide an option to wrap every column in quotation marks, you can achieve this through explicit concatenation in SQL. For wrapping columns in quotes, use the following command:

CREATE external TABLE 'c:/test_export.txt' USING (delimiter ',') AS SELECT "' || col1 || "', "' || col2 || "' FROM test_export

Using nzsql CLI Interface

Alternatively, data from Netezza can be exported using the nzsql CLI interface. While this method is slower compared to using external tables, it remains a viable option. The -o flag may be used to specify output in CSV format.

To export data using nzsql, execute the following command:

nzsql -d DB_NAME -F "," -t -A -o export.txt -c "select * from test_export"

Key Considerations

When using external tables for exporting data, ensure to mount the filesystem locally to the Netezza host. Additionally, remember that the -o flag in nzsql may sometimes cause issues; use it cautiously. Always consider efficiency and opt for external tables when performance is a priority.
