namespace constants

Abort when a change encounters a conflict and roll back database.

This constant is passed to the conflict handler while processing an INSERT change if the operation would result in duplicate primary key values.

The conflict handler is invoked with this constant when processing a DELETE or UPDATE change if a row with the required PRIMARY KEY fields is present in the database, but one or more other (non primary-key) fields modified by the update do not contain the expected "before" values.

If foreign key handling is enabled, and applying a changeset leaves the database in a state containing foreign key violations, the conflict handler is invoked with this constant exactly once before the changeset is committed. If the conflict handler returns SQLITE_CHANGESET_OMIT, the changes, including those that caused the foreign key constraint violation, are committed. Or, if it returns SQLITE_CHANGESET_ABORT, the changeset is rolled back.

The conflict handler is invoked with this constant when processing a DELETE or UPDATE change if a row with the required PRIMARY KEY fields is not present in the database.

Conflicting changes are omitted.

Conflicting changes replace existing values. Note that this value can only be returned when the type of conflict is either SQLITE_CHANGESET_DATA or SQLITE_CHANGESET_CONFLICT.
