When you need to move data from one Oracle database to another, a powerful and user-friendly tool like DBeaver can simplify the process. In this blog post, we’ll explore how you can use DBeaver to create and execute queries for copying data between Oracle databases, making the data migration process efficient and hassle-free.

Why Use DBeaver for Data Migration?

DBeaver is a popular open-source database management tool known for its versatility and compatibility with a wide range of database systems, including Oracle. Here’s why DBeaver is an excellent choice for copying data between Oracle databases:

  1. Cross-Database Support: DBeaver allows you to connect to multiple database systems simultaneously. This makes it easy to transfer data between Oracle databases or even between different database systems if needed.
  2. SQL Editor: DBeaver features a robust SQL editor with syntax highlighting, auto-completion, and query execution capabilities, making it easy to write and execute data migration queries.
  3. Data Transfer Wizards: DBeaver provides data transfer wizards that simplify the process of copying data between databases. These wizards guide you through the steps, ensuring a smooth and error-free migration.
  4. Data Visualization: DBeaver offers data visualization features, allowing you to view and validate data before and after the migration.

Copying Data Between Oracle Databases in DBeaver

To copy data between two Oracle databases using DBeaver, follow these steps:

Step 1: Connect to Databases

Open DBeaver and establish connections to both the source and target Oracle databases. Ensure you have the necessary credentials and connection details for both databases.

Step 2: Create a SQL Query

In DBeaver, open the SQL editor and write a SQL query to select the data you want to copy from the source database. For example:

SELECT * FROM source_table;

Step 3: Execute the Query

Execute the query to ensure it returns the expected data from the source database.

Step 4: Modify the Query for Insertion

To copy the data to the target database, you’ll need to modify the query to an INSERT INTO statement for the target table in the destination database. For example:

INSERT INTO target_table (column1, column2, column3)
SELECT column1, column2, column3 FROM source_table;

Step 5: Execute the Insert Query

Execute the modified query in the SQL editor. This will insert the data from the source table into the target table in the destination database.

Step 6: Verify Data Transfer

After executing the query, you can use DBeaver’s data visualization features to compare the data in both databases and verify that the migration was successful.


DBeaver simplifies the process of copying data between Oracle databases with its user-friendly interface, versatile SQL editor, and data transfer wizards. Whether you’re moving data between databases for migration, synchronization, or any other purpose, DBeaver provides a powerful and efficient solution.

Using DBeaver for data migration saves time and reduces the potential for errors, ensuring that your data is seamlessly transferred from one Oracle database to another. Try it out for your next data migration task and experience the convenience and flexibility it offers.
