How to use WKT?

Question

I am doing a database assignment (TSQL), and have been given some "Well known Text" to work with.

I have made the tables:

drop table geometry_polygons;
go
drop table geometry_points;
go
drop table geometry_linestrings;
go 
create table geometry_polygons(
    id int primary key NOT NULL,
    polygon geometry,
    label varchar(50),
    area decimal(10,4),
);
create table geometry_points(
    id int primary key NOT NULL,
    point geometry,
    label varchar(501),
);
create table geometry_linestrings(
    id int primary key NOT NULL,
    linestring geometry,
    label varchar(50),
    length decimal(10,4),
);

How Do i insert the geometry points into the tables?

I have this to work with;

Answer 1

Something like this:

declare @g geometry; 
set @g=geometry::STGeomFromText('POLYGON((175.0305935740471 -39.924665194652604,175.03033608198166 -39.924387504970255,175.0301563739777 -39.92449035313209,175.03041118383408 -39.92474952981466,175.0305935740471 -39.924665194652604))', 4326);  
insert into geometry_polygons (polygon) values (@g);

Note you have to specify a coordinate reference system, sometimes called, spatial reference system (SRS), for example, 4326, which means lat/long, for many spatial functions to work properly.

EDIT: the geometries which you have added in your updated question, are a mixture of Polygons, Linestrings and Points, so, you will need to use a GeometryCollection (which can take a mixture of types) if you want to add them all in one go, or split them into separate entries. It is generally a bad idea, though, to mix different geometry types like this, as many spatial functions don't work on GeometryCollections.
