September 14, 2026 — Withdata Software announces DBCopier 3.0, a cross-platform desktop tool for copying data between databases. This is the biggest update to DBCopier so far: a Preview Plan that shows exactly what will happen before anything is written, safer and faster update / upsert, and a long list of usability improvements for DBAs and developers.
What’s New in DBCopier 3.0
1. Preview Plan — See What Will Happen Before You Copy
Before anything is written, DBCopier 3.0 can show you the plan: the target table of every item, the field map risks, and the number of rows each item will move. Field map risks are also shown in the map dialog — NOT NULL columns, primary / unique key problems, and required columns that are not mapped. You fix problems before a run instead of after one.
2. Safer Writes on Busy Databases
A long copy no longer fails just because a database was busy for a moment. DBCopier now waits and retries on deadlock, lock timeout and lost connection, and a paused conversion is kept alive and reconnects when it resumes. Records that reported a write error are confirmed before they are called failed, and the bad record file is dropped when they all reached the table. A temporary connection problem is no longer reported as an error — only real data errors raise the error dialog.
3. Faster Update and Upsert
- Choose an update key per item (“Click To Config”), including multi-column keys.
- An index is created on the update key automatically, so update and upsert are much faster.
- Update and upsert are written in batches on SQL Server and Oracle.
- Tables created by a run now get a primary key.
4. Better Control, Logging and Notifications
- New “Options / Settings”; the log filter and the finish notification are kept for the next run.
- A log filter by level, keyword, or only the current item, plus Copy Log / Save Log in the output windows.
- “Notify me when the conversion is done”, with an optional sound.
5. Field Mapping, Sessions and Other Improvements
- Save, load and clear the field mapping of a session; the mapping is fixed automatically after the source columns changed; losing the target tables when a session was loaded is fixed.
- Editing the structure of a SQLite table: drop a column and rebuild the table.
- Copy Names / Export DDL / Drop Selected, and a search filter in the object tree.
- Some minor bug fixes and improvements.
