如何在POINT中使用MySQL变量

Question

I am trying to use a MySQL variable together with POINT like this (simplified):

SET @lat=145.033667; SET @long=-37.932000; INSERT INTO Location(position) values (GeomFromText(‘POINT(@lat @long)'));

This works fine:

SELECT 'POINT(145.033667 -37.932000)';

As does this:

SELECT GeomFromText('POINT(145.033667 -37.932000)');

Is there anyone who know how I can make this work?

Answer 1

I think you have a syntax error:

SET @lat=145.033667; 
SET @long=-37.932000; 
INSERT INTO Location(position) 
values (GeomFromText('POINT(@lat @long)'));
