Hi all,
I am trying to use PreparedStatement to get a buffer of a geometry invoking the commands bellow
PreparedStatement st = con.prepareStatement("CREATE TABLE geom (g
geometry)"); st.execute(); st = con.prepareStatement("INSERT INTO geom VALUES(GeomFromText('POINT(1 1)', 2100))"); st.execute(); st = con.prepareStatement("SELECT Buffer(t.g, ?) AS buffer, t.g AS point FROM geom AS t"); // This line throws an SQLException st.setFloat(1, (float)1.0); ResultSet results = st.executeQuery();
However the fifth line throws an SQLException with this message:
types geometry(0,0) and double(53,0) are not equal
Replacing the question mark with a number (e.g. 1.0) the program executes properly.
Why is this exception thrown? Is something wrong in my code?
Thanks in advance, George Garbis
