Hey All,<br>
<br>
As some of you know, I've been trying to connect a point from a point table to the projection of that point on the nearest line for close to forever now.<br>
<br>
I've managed to get the code working for a small set of points and lines; however, on a 60 node with 2,000 lines, the query is in its 11th hour and still no sign of ending.<br>
<br>
I posted a question including code on stack overflow <a href="http://stackoverflow.com/questions/1504353/slow-postgres-query" target="_blank">http://stackoverflow.com/questions/1504353/slow-postgres-query</a><br>
<br>
I was wondering if anyone here has any idea on what I might be doing wrong ? and if there is a way to make the code more efficient<br>
<br></blockquote></div><br>Hum, I am no expert but it looks like your 3000000 is way too high. I think you need to tune your query to values that makes more sense in your current srid.<br>I am using the same function on a table with a huge number of lines (read several millions), and it works quite fast for me.<br>
