']} and lng$squares[' Right-bottom '] [' LNG ']} ";After establishing a federated index on LAT and LNG, using this query, the average query consumption per record is 0.8 milliseconds, compared to the previous 1700ms, it is really a great difference. Efficiency really is 2,125 times times the previous ~ ~Summary: This should not be the best way to be efficient, but the efficiency is actually significantly higher than before. Please keep in mind that there is always a better way.Originally from:

I want to query the five locations in the vicinity of two kilometers in the data table based on the longitude and latitude of the current location, if the query result does not have five locations, I want to expand the nearby range until the five locations are queried.

As a beginner, but also self-study, a simple problem for others, for themselves is like an insurmountable mountainBut when the problem is solved by itself, the joy is unspeakable.Recently in a multi-point location display, before doing a single-point positioning display of small cases, I would like to apply that, but did a lot of trying to find that noLater consulted a lot of information, but also combined with Baidu map demo, finally in accordance wi

the current time TimeNow, based on the time difference between TimeNow-TimeStart and the walking speed of the role, obtain the distance that the role has traveled, calculate the distance between each two points, and determine the path of the role's current time, and between the two roles. Then, use the vector calculation formula to calculate the coordinates of the current role. Class encapsulation implementation code for role

3D server-side player walking processing is used by the server to calculate the current position of the Player Based on the client path, player walking time, and speed (including the variable speed. Because client walking is a path, the grid computing algorithm in 2D is not used, and the current position of the role cannot be efficiently obtained. The amount of walking paths, walking speed, and walking time used by players has been reached, calculate

There are three types of CSS selectors. ① contextual selectors; ②id and class selectors; ③ property selectors, and the biggest benefit of contextual selectors is that it's convenient to add styles based on location for HTML elementsFor example, we want the P tags in the article and aside tags to set different stylesThe contextual selector is also called the descendant combination selector, which is separate
