Exporting Data to CSV from HANA Studio
- Using HANA Studio is the fastest method to export data to CSV. This process leverages the built-in export options provided by HANA Studio to efficiently handle large datasets. The method ensures quick and efficient data export, outperforming other command-line interface (CLI) methods.
- Exporting data from HANA Studio to CSV involves first pushing the query results into a table. This step can be achieved using the `CREATE AS SELECT` statement, which creates a new table and populates it with the query results. Note that this step introduces some overhead time but is necessary for the export process.
- Once the data is prepared and stored in a table, the `EXPORT` command in HANA Studio can be used to export the data to a CSV file. The `EXPORT` command can target either a file or a temporary table. Although exporting to a temporary table is faster, it is not well-documented. Regardless, using the `EXPORT` command ensures a swift transfer of data to CSV format.
- To begin the export process in HANA Studio, follow these steps: 1. Use `CREATE AS SELECT` to push the query data into a table.2. Use the `EXPORT` command to export this table's data into a CSV file.This combination of steps leverages HANA Studio's capabilities to ensure a fast and efficient export process.
- On average, exporting a 600MB dataset to CSV using HANA Studio takes about 6 seconds. This performance is notably faster than other methods, underscoring HANA Studio's efficiency in handling large data exports. Utilizing a temporary table can further accelerate the export process, although it may not be documented comprehensively.
- HANA Studio provides an efficient and fast method for exporting data to CSV. By pushing query results into a table and using the `EXPORT` command, users can quickly transfer large datasets to CSV files. This method is superior to CLI options and ensures the data is handled properly and exported swiftly.

How to Export Data to CSV Format from Hana Studio
Overview
Exporting data to CSV format from Hana Studio is an efficient way to handle large datasets. This guide will walk you through the steps required to export your data to CSV using various methods provided within the Hana Studio interface.
Fastest Method Using Temporary Tables
To achieve the fastest export, use a temporary table. First, create a temporary table to store the data you wish to export. Populate the temporary table using the CREATE AS SELECT command. Then, use Hana Studio's export functionality to export the data from the temporary table to a CSV file. This method can export a 600MB dataset in approximately six seconds.
Steps to Export Data to CSV
To export a table to CSV, follow these steps:
1. Select the Export option from the File menu.
2. Type “Catalog” in the search box and select the Catalog Object option. Click Next.
3. Choose the Source Hana Database and click Next.
4. Select the table you wish to export from the list of available tables.
5. Configure the export options on the next screen. Choose the CSV format.
6. Select the option to include data if you want to export the table with its data.
7. Choose the location for the export and click Finish to complete the process.
Export Using SQL Statements
Hana Studio also supports exporting data using SQL statements. To export data, use the EXPORT INTO CSV FILE statement. If you need to import this file later, use the IMPORT FROM CSV FILE statement followed by the LOAD TABLE statement to load the data into a table.
Exporting to Cloud Storage
Hana Studio can export data to various cloud storage providers such as Amazon S3, Google Cloud, and Microsoft Azure. Ensure you use the correct credentials to access these services. You can export your data in CSV or Parquet formats depending on your requirements.
Using the Export Data Wizard
The Export Data Wizard in Hana Studio simplifies the data export process. Access the wizard via the Hana Studio interface, choose the table or query you wish to export, and follow the prompts to complete the export. You can choose CSV as the target format and specify the export location, making the process user-friendly and efficient.
