DBCopier 3.1 Released: Automate Database Copies from the Command Line

November 3, 2026 — Withdata Software announces DBCopier 3.1, a cross-platform desktop tool for copying data between databases. This release makes the copy itself a first-class command line job: one command describes the whole copy, a dry run shows the plan before anything is written, and a batch file or a scheduler can trust the exit code.

What’s New in DBCopier 3.1

1. A Complete Command Line for Copy Jobs

One command describes the copy — source, target, tables and the load type:

DBCopier copy --from="SQLite:shop.db" --from-table=customers --to="MySQL:user:pass@host:3306/shop" --to-table=customers --loadtype=upsert

• The table form (one table, several tables, or N tables into N tables), and the query form with --from-sql or --from-sql-file.
• --set=Section.Name=Value overrides any value of the session, and --var / --var-file expand ${...} variables (dates, environment, secrets) inside it.
• A dry run that prints the plan — the target table, the field map risks and the row count of every item — as --dry-run, --json or --report=plan.json.
• The whole contract in --help: --version, schema, init, describe, schedule, capabilities, pipeline and mcp.

2. Exit Codes a Batch File Can Trust

A copy that wrote nothing, or only some of the rows, is not a successful run. DBCopier 3.1 exits non-zero in both cases, and the log says how many rows were written and how many failed — so a nightly job, a batch file or a scheduler can tell a clean copy from a broken one without reading the log first.

3. GTK3 Linux Packages and Dialog Polish

• The Linux builds use GTK3, with apt and rpm repositories, so DBCopier runs on current Linux desktops.
• The logon dialog is cleaner: Ok / Cancel on the right, and a connection error in a popup instead of a memo at the bottom.
• The start-a-task dialog shows saved sessions as speed buttons and no longer overlaps controls on GTK3.
• The page tabs show the source and destination type of the current task.
• On macOS, the wizard now loads its steps when it is started from the application’s main form, and Back no longer reloads the step.

4. Other Improvements

Some minor bug fixes and improvements.
