Types

type Max

type Max struct{}

Max represents struct used to setting new autoincrement value using simple "SELECT MAX(ID)" approach

func (*Max) CanUse

func (n *Max) CanUse(iopts ...interface{}) bool

CanUse returns true if Handle function can be executed

func (*Max) Handle

func (n *Max) Handle(ctx context.Context, db *sql.DB, target interface{}, iopts ...interface{}) (doNext bool, err error)

Handle sets new autoincrement value using simple "SELECT MAX(ID)" approach

type Next

type Next struct{}

Next represents struct used to setting new autoincrement value using insert inside new transaction finished by rollback

func (*Next) CanUse

func (n *Next) CanUse(iopts ...interface{}) bool

CanUse returns true if Handle function can be executed

func (*Next) Handle

func (n *Next) Handle(ctx context.Context, db *sql.DB, target interface{}, iopts ...interface{}) (doNext bool, err error)

Handle sets new autoincrement value by inserting row using new transaction finished by rollback, uses locking
