示例1: Where

// Where is for fetching specific records
func (d *Driver) Where(tablename string, fields []field.Field, ctx context.Context, where string, args ...interface{}) ([][]field.Field, error) {
	if tx := ctx.GetTx(); tx != nil {
		return tx.(*Driver).Where(tablename, fields, ctx.SetTx(nil), where, args...)
	}

	result := [][]field.Field{}

	fn, ok := d.whereRegistry[where]
	if !ok {
		return nil, fmt.Errorf(
			"Fake driver has no '%s' where query registerd, please register with RegisterWhere",
			where,
		)
	}

	for _, record := range d.getTable(tablename) {
		ok, err := fn(record, args...)
		if err != nil {
			return nil, fmt.Errorf("Registered query '%s' returned error - %s", where, err)
		}

		if ok {
			result = append(result, record)
		}
	}
