Import QVD to MariaDB Automatically
Importing QlikView QVD files into MariaDB can be challenging if you're relying on custom scripts or manual workflows. With Advanced ETL Processor, you can fully automate the QVD-to-MariaDB import process - without writing a single line of code.
What Is a QVD File?
A QVD (QlikView Data) file is a proprietary data format used by QlikView and Qlik Sense to store structured datasets. QVDs are optimized for fast data access within the Qlik ecosystem, but not directly supported by relational databases like MariaDB.
Why Import QVD into MariaDB?
- Run complex SQL queries on QlikView data using standard tools
- Combine QVD data with operational systems for unified reporting
- Make Qlik data available to dashboards, APIs, and web applications
How to Import QVD to MariaDB - Step-by-Step
1. Launch Advanced ETL Processor
Open the Enterprise Edition of Advanced ETL Processor. Make sure your MariaDB and QVD connections are properly set up by going to Tools > Connections.
2. Create a New Transformation
Select or create a transformation group. Right-click on the group and choose New to open the dataflow canvas.
3. Configure the QVD Reader
- Drag the QVD Reader component onto the canvas
- Double-click it to select the source file and view its structure
4. Add a MariaDB Writer
- Drag the MariaDB Writer onto the canvas
- Select the target database, schema, and table where data will be loaded
5. Map and Transform Fields
Connect fields between the QVD source and MariaDB destination manually or use the AutoMap feature. You can apply transformations such as trimming, formatting, or type conversion directly within the visual interface.
6. Execute the Transformation
Click Execute to perform a one-time import. You can also save the transformation to run it on a schedule or reuse it in automated workflows.
7. Schedule and Monitor
- Use the built-in scheduler to automate data loading
- Trigger transformations based on file availability or system events
- Enable logging, error handling, and rollback on failure
Where this import fits
Import QVD to MariaDB is useful when QVD data needs to feed MariaDB, reporting databases, operational systems, migration jobs, or downstream ETL workflows. Use it when the same import needs validation, mapping, transformations, scheduling, and logs instead of another manual load.
Do not automate the import until the source layout, target table, key fields, write mode, and failure behaviour are agreed. Automation repeats rules; it does not rescue unclear ones.

Business usage examples
Qlik reporting archive
Load QVD extracts into MariaDB so reporting teams can query historical Qlik data outside the dashboard layer.
BI migration staging
Move QVD data into MariaDB staging tables before validation, reconciliation, and warehouse loading.
Scheduled analytics feed
Import recurring QVD files into MariaDB with logs and rejected-row handling instead of manual export steps.

FAQ
Can Advanced ETL Processor import QVD to MariaDB?
Yes. Advanced ETL Processor can read QVD, map fields, validate data, write to MariaDB, and log the import.
Do I need to write scripts for the import?
No scripting is required for the normal import workflow. You can configure the reader, writer, mapping, validation, and schedule visually.
Can the QVD import run on a schedule?
Yes. The package can run on a schedule, process matching QVD files, archive originals, and write rows to MariaDB with the same validation rules each time.
Can imported data be transformed before loading?
Yes. You can clean values, convert data types, calculate fields, split columns, and apply lookup rules before writing to the target.
Can bad rows be logged or rejected?
Yes. Add validation rules so rejected rows, failed files, row counts, and error details are visible after each run.
What should I check before the first production import?
Check source layout, target table, key fields, data types, date formats, write mode, archive folder, and failure handling.
When should I not automate the import yet?
Do not automate it until the source layout, target table, key fields, and bad-row handling are clear. Automation repeats rules; it does not invent them.
Can I test the import before buying?
Yes. Download the fully functional 30-day trial, build one small import, and test it with a deliberately awkward sample file.
