## DbSequence::set_flags()

    #include <db_cxx.h>

    int
    DbSequence::set_flags(u_int32_t flags);

Configure a sequence. The flags are only effective when creating a sequence. Calling `DbSequence::set_flags()` is additive; there is no way to clear flags.

The `DbSequence::set_flags()` method may not be called after the DbSequence::open() method is called.

The `DbSequence::set_flags()` method either returns a non-zero error value or throws an exception that encapsulates a non-zero error value on failure, and returns 0 on success.

### Parameters

#### flags

The flags parameter must be set to 0 or by bitwise inclusively OR'ing together one or more of the following values:

- `DB_SEQ_DEC`

  Specify that the sequence should be decremented.

- `DB_SEQ_INC`

  Specify that the sequence should be incremented. This is the default.

- `DB_SEQ_WRAP`

  Specify that the sequence should wrap around when it is incremented (decremented) past the specified maximum (minimum) value.

### Errors

The `DbSequence::set_flags()` method may fail and throw a DbException exception, encapsulating one of the following non-zero errors, or return one of the following non-zero errors:

#### EINVAL

An invalid flag value or parameter was specified.

### Class
