Commit hook requested rollback

Category: ConstraintVersions: 3.0+

🔴 Production Risk Error

Medium — transaction rolled back by application design.

What this means

SQLITE_CONSTRAINT_COMMITHOOK (531) is returned when a commit-hook callback (registered via sqlite3_commit_hook()) returns non-zero, requesting that the transaction be rolled back.

Why it happens

1Application commit hook returned non-zero to veto the commit.
2Custom validation logic in the commit hook rejected the transaction.

How to reproduce

COMMIT when a registered commit hook returns non-zero.

trigger — this will ERROR

# In C:
# sqlite3_commit_hook(db, myCommitHook, NULL);
# If myCommitHook() returns 1 → SQLITE_CONSTRAINT_COMMITHOOK

sqlite3.OperationalError: constraint failed

Fix 1

Why this works

Review the commit hook logic — it intentionally vetoed the commit.

Fix 2

Why this works

Fix the data or transaction to satisfy the commit hook's validation.
