Question

I have a .NET application which executes a statement like this:

SELECT ST_GeomFromKML('
        <LineString>
            <coordinates>-71.1663,42.2614 
                -71.1667,42.2616</coordinates>
        </LineString>');

There is no need for tables or where clause, I’m basically using it as a converter.

So my question is does my application hit the database when i issue this command or does the local postgress dll take care of it in memory?

Answer 1

It will hit the database, which basically means that it will be much slower than it needs to be.

You should try to write a method thaat performs the conversion without using the database, and call that method instead.
