有没有办法使用MySQL函数从纬度，经度获取POINT坐标？

Question

I need to get mercator coordinates from Lat , Lng in Node.js. I can use some module (for example, node-sphericalmercator ). But it means that the calculation is done on the Node server, not in MySQL:

// Here is pseudo code example
var sphericalmercator = new Sphericalmercator();

res = "SELECT ALL lat, lng FROM table"

var rs = res.map(function(row) {
    return [sphericalmercator.forward([row.lng, row.lat])]
});

// and only then I can do subsequent INSERTs.
INSERT INTO table VALUES POINTFROMTEXT("POINT(rs[0] rs[1])")

But I'd like to covert Lat , Lng into POINT straightly in MySQL, not on Nodejs server. Is there some functions for this?

INSERT INTO table VALUES SomeFuncThatTraslatesToPoint(Lng, Lat)

Answer 1

I admit i'm no expert, but is this something like what you're trying to do?

Moving lat/lon text columns into a 'point' type column

Specifically the section regarding GeomFromText(CONCAT('POINT(', lat, ' ', lng, ')'))
