product, but unlike the Cartesian product, the data table of the product of the number of rows of the Cartesian product is not so complicated that the inner connection is more efficient than the cross-connection of the Cartesian product. Finally, the cross join, if there is a WHERE clause, will tend to be the data table of the row that is the product of the two table row numbers and then select from the Where condition. Therefore, if the data volume of two tables is too large, it will be very,

However, the disadvantage of using push is:For clients: Relatively high cost of implementation and maintenance, the maintenance of long connections under the mobile wireless network, relative to some technical development
