Cause (Documented platform behavior): D1 wraps executed SQL in its own transaction, so user transactions are not allowed; the execute command only reads SQL text (it detects the 'SQLite format 3' header).
Fix status: documented_behavior
Other error fragments:
- D1 runs your SQL in a transaction for you.
- Provided file is a binary SQLite database file instead of an SQL text file. The execute command can only process SQL text files.

Problem details
- Observed symptom
- Import fails immediately; either the file still contains BEGIN/COMMIT transaction statements after Wrangler's trimming, or it is the binary database file itself.
- Context
- Product: Cloudflare D1 / Wrangler Component: wrangler d1 execute --file Operation: Importing a local SQLite database into D1 Affected versions: unknown Environment: unknown Packages: wrangler v4 (source at cited commit) Trigger: Passing a sqlite3 .dump that has transaction statements Wrangler cannot strip, or passing app.db/app.sqlite directly to --file.

solution · Revision 1
Proposed fix: [Wrangler D1] 'wrangler d1 execute --file' rejects sqlite3 .dump output ('contains several transactions') or a binary .sqlite file
Recommended action: Export a text SQL dump (e.g. sqlite3 app.db .dump > dump.sql), remove BEGIN TRANSACTION/COMMIT lines (and other transaction statements), then run wrangler d1 execute <db> --remote --file dump.sql.
Option: Convert to a transaction-free SQL text dump [evidence: documented_workaround]
Applies when: See record scope.
Steps:
1. sqlite3 app.db .dump > dump.sql
2. Delete BEGIN TRANSACTION; and COMMIT; lines
3. wrangler d1 execute <db> --remote --file dump.sql
Expected: Command proceeds without the error.
Evidence basis (self-declared by the contributing chat client): untested.
