sync2不支持同步mysql中MEMORY引擎的数据表V0.7.0

[ependi-buzz]

func (db *mysql) GetTables() ([]*core.Table, error) {
	args := []interface{}{db.DbName}
	s := "SELECT `TABLE_NAME`, `ENGINE`, `TABLE_ROWS`, `AUTO_INCREMENT`, `TABLE_COMMENT` from " +
		"`INFORMATION_SCHEMA`.`TABLES` WHERE `TABLE_SCHEMA`=? AND (`ENGINE`='MyISAM' OR `ENGINE` = 'InnoDB' OR `ENGINE` = 'TokuDB')"
	db.LogSQL(s, args)

	rows, err := db.DB().Query(s, args...)
	if err != nil {
		return nil, err
	}
	defer rows.Close()

	tables := make([]*core.Table, 0)
	for rows.Next() {
		table := core.NewEmptyTable()
		var name, engine, tableRows, comment string
		var autoIncr *string
		err = rows.Scan(&name, &engine, &tableRows, &autoIncr, &comment)
		if err != nil {
			return nil, err
		}

		table.Name = name
		table.Comment = comment
		table.StoreEngine = engine
		tables = append(tables, table)
	}
	return tables, nil
}

不会获取MEMORY引擎的数据表
