Export SQL Server Data to Oracle Database

Export Data from SQL Server to Oracle Database

Preparing for Migration

Begin by generating scripts of SQL Server table structures and modify them to meet Oracle syntax requirements. For large data migrations, consider an ETL/EAI tool. Ensure the CSV files created by the SQL Server export wizard are quoted.

Using Oracle SQL Developer

Leverage Oracle SQL Developer, a free tool provided by Oracle, to facilitate the migration process. This tool is fully supported and optimized for migrating data using a migration repository which houses metadata essential for the transformation and migration stages.

Migration Repository Setup

Initiate the process by setting up a Migration Repository. This repository is crucial for storing metadata that aids in the data migration process.

Database Connection Configuration

Proceed to configure the connection to the third-party SQL Server database. A secure and accurate connection is necessary for a smooth migration experience.

Capturing Source Database

Next, capture the source database. This step is pivotal in collecting the necessary metadata for the migration.

Model Conversion to Oracle

Convert the captured model to Oracle's format. This ensures compatibility and prepares the database structure for the subsequent steps.

Translation of T-SQL Objects

Translate T-SQL objects into their Oracle equivalents. This translation is essential for maintaining the logic and functionality of the database in the new environment.

Script Generation for Target Database

Generate scripts to create the Oracle target database. These scripts are derived from the converted models and translated objects.

Data Movement to Oracle Database

The final step involves moving the data to the newly prepared Oracle database, completing the migration process. The migration repository aids in this process by using the stored metadata to streamline the data transfer without querying the live database.

Frequently Asked Questions

What tools can I use to export data from SQL Server to an Oracle database?

You can use Database Tour or Oracle SQL Developer to export data from a SQL Server database to an Oracle database.

Do I need to prepare anything before exporting data using Database Tour?

Yes, both the source SQL Server and the target Oracle databases should be registered and they must support the same architecture before configuring the export in Database Tour.

What options should I use in Database Tour for exporting large datasets?

For exporting large datasets, it is recommended to use Memory saving mode, Use SQL Parameters, Batch mode options, and set a Commit interval.

How do I migrate data using Oracle SQL Developer?

To migrate data using Oracle SQL Developer, set up a migration repository, capture a snapshot of the current state of SQL Server, convert the model to an Oracle-specific model, translate T-SQL objects to Oracle SQL objects, and use the generated SQL scripts to create the new Oracle schema and move the data.

Can I perform data export from the command line?

Yes, exporting data from the command line is available with Database Tour Pro and Oracle Database XE provides command-line utilities as well.
