[postgis-users] populatong a postgis via Javaappl.

[Malm Paul]

I would like to insert a point in a postgis database.

BEGIN;
INSERT INTO "public"."ais" ("mmsi", the_geom) 
VALUES ('123', ,GeometryFromText('POINT(-73.910977172366
40.729270630126)',-1));
END;

This is what I have tried in java.

static private Connection con = null;
double lat 63.049813568477724;
double lon 20.26472335111486;

Class.forName(org.postgresql.Driver);
con = DriverManager.getConnection("jdbc:postgresql:postgis", "username",
"pw");
PreparedStatement stmt = con.prepareStatement("insert into ais (mmsi,
the_geom) " + "values(?,  ?)");
stmt.setString(1, "abc");
stmt.setString(2, "GeometryFromText('POINT(" + lat + " " + lon +
")',-1)");
System.out.println(stmt);
stmt.executeUpdate();

This is what System.out.println prints:
insert into ais (mmsi,  the_geom) values(abc,
GeometryFromText('POINT(63.049813568477724 20.26472335111486)',-1))

This is the Error message
org.postgresql.util.PSQLException: ERROR: column "the_geom" is of type
geometry but expression is of type character varying

 

Could someone please tell me where I can read about how to do this, or
if someone could send me a little example? I have not found any
documentation that shows this (at least as far as I understand I'm new
at both Java and SQL).

This must be a basic thing, but I don't get it...

Thanks..
