ibm informix spatial datablade select statement error
- by changed
Hi
I am using IBM informix spatial datablade module for some geo specific data.
I am trying to find points in table xmlData lying in a specified region.
But i am getting this error for select statement.
SELECT sa.pre, sa.post
FROM xmlData sa
WHERE ST_Contains( ST_PolyFromText('polygon((2 2,6 2,6 6,2 6,2 2))',6),sa.point)
Query:
select count(*) as mycnt fromText('polygon((2 2,6 2,6 6,2 6,2 2))',6),sa.point)
Error: -201
[Informix][Informix ODBC Driver][Informix]A syntax error has occurred. (SQLPrepare[-201] at /work/lwchan/workspace/OATPHPcompile/pdo_informix/pdo_informix/informix_driver.c:131)
If any one can help me with this.
CREATE TABLE xmlData (row_id integer NOT NULL,
x integer,
y integer,
tagname varchar(40,1),
point ST_POINT
);
EXECUTE FUNCTION SE_CreateSRID(0, 0, 250000, 250000,
"use the return value in next query last column");
INSERT INTO geometry_columns
(f_table_catalog, f_table_schema, f_table_name,
f_geometry_column, geometry_type, srid)
VALUES ("mydatabase", -- database name
"informix", -- user name
"xmlData", -- table name
"point", -- spatial column name
1, -- column type (1 = point)
6); -- srid //use value returned by above query.
INSERT INTO xmlData VALUES (
1, 20,20, 'country',
ST_PointFromText('point (20 20)',6)
);
INSERT INTO xmlData VALUES (
1, 12,13, 'sunday',
ST_PointFromText('point (12 13)',6)
);
INSERT INTO xmlData VALUES (
1, 21,22, 'monday',
ST_PointFromText('point (21 22)',6)
);
SELECT sa.pre, sa.post
FROM xmlData sa
WHERE ST_Contains(
ST_PolyFromText('polygon((1 1,30 1,30 30,1 30,1 1))', 6),sa.point);
I am using following query as reference "ibm link".
SELECT name, type, zone FROM sensitive_areas
WHERE SE_EnvelopesIntersect(zone,
ST_PolyFromText('polygon((20000 20000,60000 20000,60000
60000,20000 60000,20000 20000))', 5));
