Member Name | Description |

Abort | When a constraint violation occurs,no ROLLBACK is executed
so changes from prior commands within the same transaction
are preserved. This is the default behavior.
|
Fail | When a constraint violation occurs, the command aborts with a return
code SQLITE_CONSTRAINT. But any changes to the database that
the command made prior to encountering the constraint violation
are preserved and are not backed out.
|
Ignore | When a constraint violation occurs, the one row that contains
the constraint violation is not inserted or changed.
But the command continues executing normally. Other rows before and
after the row that contained the constraint violation continue to be
inserted or updated normally. No error is returned.
|
None | Use the following when no conflict action is specified.
|
Replace | When a UNIQUE constraint violation occurs, the pre-existing rows that
are causing the constraint violation are removed prior to inserting
or updating the current row. Thus the insert or update always occurs.
The command continues executing normally. No error is returned.
If a NOT NULL constraint violation occurs, the NULL value is replaced
by the default value for that column. If the column has no default
value, then the ABORT algorithm is used. If a CHECK constraint
violation occurs then the IGNORE algorithm is used. When this conflict
resolution strategy deletes rows in order to satisfy a constraint,
it does not invoke delete triggers on those rows.
This behavior might change in a future release.
|
Rollback | When a constraint violation occurs, an immediate ROLLBACK occurs,
thus ending the current transaction, and the command aborts with a
return code of SQLITE_CONSTRAINT. If no transaction is active
(other than the implied transaction that is created on every command)
then this algorithm works the same as ABORT.
