Query with two spatial operators

Hi,
I need prepare query with sdo_any_interact and sdo_filter
Following query doesn't work any ideas?
SELECT ROWID, GEOMETRY, 'MVDEMO:L.MAJOR TOLL ROAD', null, 'null', -1, 'rule#0'
FROM PARCELS P
WHERE SDO_ANYINTERACT(P.GEOMETRY,
(SELECT L.GEOMETRY
FROM SHP_SIMPLYFIED L
WHERE L.TASK = '4')) = 'TRUE'
and MDSYS.SDO_FILTER(P.GEOMETRY
, MDSYS.SDO_GEOMETRY(2003
, 2180
, NULL
, MDSYS.SDO_ELEM_INFO_ARRAY(1, 1003, 3)
, MDSYS.SDO_ORDINATE_ARRAY(482850, 236980, 510333, 248133))
--, MDSYS.SDO_ORDINATE_ARRAY(:MVQBOXXL, :MVQBOXYL, :MVQBOXXH, :MVQBOXYH))
, 'querytype=WINDOW') = 'TRUE'
Kind regards,
Tomek

Hi Jack,
Join - the same error:
the error is
ORA-00904: "MDSYS"."SDO_PQRY": invalid identifier
00904. 00000 - "%s: invalid identifier"
*Cause:
*Action:
Error at Line: 13 Column: 60
TASK column - is not null, unique
parcels are partitioned table (3 000 000 rows)
i think this error is connected with partitoning
in the first version i put any_interact into view with read only option
select * from this view works fine but take a long time,
next i build theme in MapBuider but preview return error (same), (MapBuilder buid query on view and add query_window filter to reduce number of objects)
Thx,
Tomek

Crystal report based on BW query with two structures

Hi,
I use a BW query with 2 structures. In the rows there is a structure of restricted characteristic 0material. I used this characteristics several times in different rows to restrict these rows to specific products.
Cars
motorcycles
Others
In the columns I have a structure of key figures. Every key figure is restricted to a specific time intervall.
So in BW the executed query looks like this:
                       Key figure 1         Key figure 2        Key figure 3
Cars                   10                     30                         100
motorcycles        20                   100                          30
Others                30                    40                           39
If I use the same query in Crystal then I have access to the 3 keyfigures and to one structure element.
How can I ensure that the query is displayed in CR like in BW? I tried to work with crosstabs but I was not able to get the same display like in BW.
Thanks for any help.

i think this be must to tax indicator, because in the document i use two diferent taxcode. i need help to avoid this error, if somebody know how resolved, me will great util

Well Gordon,
If you see in the statement, the register is in one line:
(SELECT sum(T12.[LineTotal]) FROM PCH1 T12 INNER JOIN OPCH T10 ON T12.[DOCENTRY] = T10.[DOCENTRY] WHERE T12.[AcctCode] != '11209' AND T12. [TaxCode] = 'IVACCF' AND T12.[DOCENTRY] = T0.[DOCENTRY] AND T10.[TaxDate] >= '[%0]' and T10.[TaxDate] <= '[%1]')
to better expalin.
i have this line without tax, i only need a statement in the that be sum, the line of tax exempt + line without tax + tax total.
if you see in the query, i've excluded the acctcode = '11209', really without this filter, only i need select the doctotal to view the result. but if, i do a statement where only excluide the document line where appear this account, the quey returns a wrong

Query with two filter prompts(phase and document)

Hi All,
I am new to sap sourcing.
I am trying to customize a query for (Sourcing Report for all supplier registrations showing the cycle times for each
approval phase of the process)which I have added two filter prompts(phase and document name).
When I try to execute the query, I don't get the required output for the phase filter prompt.
Also phase is a value list and when I select the phase from the drop down, the report doesn't give any value.
Please find the query as mentioned.

Please suggest how can I change the query accordingly.
Also , please suggest how can add the result fields for calculating the duration(created at - Action date).
Please do the needful.
Thanks and Regards

Hello Vignesh,
Thank you!!
I could find that only the supplier registration modifications are included in the query given by you, but we need to include the supplier registrations as well.
I tried modifying the query and it worked.
But, now the challenge is to include the workflow status(T1.APPROVAL_STAUS) in the filter prompt.
T1 table is FCI_WORK_ITEM.
T.APPROVAL_STAUS is an integer data type in the table.
I defined the T.APPROVAL_STAUS as string In Result fields and in the filter prompt.
But the query works for other filter prompts except workflow status.
I have included the filter prompts as mentioned below:
T1.CONTEXTID=<%CONTEXT(workflow.process)%> AND
UPPER(T2.BIZ_DOC_OBJECT_NAME) like ? AND
UPPER(T2.PHASE_SUB_REF_OBJECT_NAME) like ? AND
UPPER(T1.APPROVAL_STATUS) like ? AND
UPPER(T1.PERFORMER_OBJECT_NAME) like ?
<%ORDERBY%>
Please suggest on this.
Thanks and Regards

Query with two where conditions

HI
SELECT ENAME FROM EMP WHERE
SAL > 1000 AND JOB='CLERK';
How to implement in CMP(Entity bean)
thank u

at this point mapping to do this king of query would be on the container specific file. I will tellyou how this is done on a Orion App server. I bet that others are close to the same.
first you make a finder method in your bean for the enploy name:
Collection findBigClerk();
Orion generates a file from the ejb-jar.xml file called orion-ejb-jar.xml. this is where the O/R mapping is changed for the beans.
each method in a bean has short definition
<finder-method query="EMP.SAL>1000 and EMP.JOB='CLERK'">
Assuming that the CMP is mapped to the EMP table when you call findbigClerk it will add the above query to as a WHERE clause.
Then get the name from the interface.
Again, this is how I would do this on an Orion App server. Others will be simular until O/R mapping is moved from server-specific to the ejb-jar.xml file
hope this helps a little

Best practice for use of spatial operators

Hi All,
I'm trying to build a .NET toolkit to interact with Oracles spatial operators. The most common use of this toolkit will be to find results which are within a given geometry - for example select parish boundaries within a county.
Our boundary data is high detail, commonly containing upwards of 50'000 vertices for a county sized polygon.
I've currently been experimenting with queries such as:
select
from
uk_ward a,
uk_county b
where
UPPER(b.name) = 'DORSET COUNTY' and
sdo_relate(a.geoloc, b.geoloc, 'mask=coveredby+inside') = 'TRUE';
However the speed is unacceptable, especially as most of the implementations of the toolkit will be web based. The query above takes around a minute to return.
Any comments or thoughts on the best practice for use of Oracle spatial in this way will be warmly welcomed. I'm looking for a solution which is as quick and efficient as possible.

Thanks again for the reply... the query currently takes just under 90 seconds to return. Here are the results from the execution plan ran in sql*:

Select query with UNION clause in database adapter

Friends,
I have got a SQL query with two UNION clause withing it. like
select a,b,c
from a
union
select a,b,c
from b
The schema generated is like below in sequence
<element>a</element>
<element>b</element>
<element>c</element>
<element>a</element>
<element>b</element>
<element>c</element>
So, the columns from different select queries joined with UNION clause are all appeared in schema instead of the distinct columns.
Is there any way around to solve this issue ? or will need to with DB function/procedure.

I think I know what you are saying but your example doesn't make sense, your SQL should produce something like
I had to change a, b, c with elementA, elementB, elementC as a and b are reserved html tags.
<elementA>DateA</elementA>
<elementB>DataB</elementB>
<elementC>DataC</elementC>
...What is the result of the query when you run it in SQLPlus? Is it what you expect?
cheers

Send values to IN query with parameter

Subject: send values to IN query with parameter
Hello. Hope I'll explain my problem well enough:
I have a query:
-- select id from table where id in ('100')
Now I used parameter for the IN part:
-- select id from table where id in (:param)
and I gave the parameter the value 100.
now I want to have the query with two values:
-- select id from table where id in ('100','200')
I tried to use the parameter and give him the value of: '100','200'.
It didn't worked :(
Is there a syntax to give the parameter more then one value for the IN query (with out using another table or function etc')?
Thanks in advance,Roy.

This is the best solution I have for it.
variable parameter varchar2(4000);
exec :parameter := 'SYSTEM,SYS';
select username
from dba_users
where username in ( select COLUMN_VALUE from table (split_string(:parameter,',')))It uses this function
CREATE OR REPLACE
type string_table as table of varchar2(4000)
CREATE OR REPLACE
FUNCTION split_string (
     string IN varchar2,
    delimiter IN varchar2
) RETURN string_table IS
     tab string_table;
     pre integer;
     post integer;
     step integer;
     i integer;

     pre := 1;
     step := length(delimiter);
     i := 0;
     tab := string_table();
     loop
          tab.extend;
          i := i + 1;
          post := instr(string,delimiter,pre);
          if ( post = 0 ) then
               tab(i) := substr(string,pre);
               return tab;

Query with 2 variables

I have a query with two variables (Employee and Date). The query is working fine if both of the variables are check and values assigned. But if only one variable is checked and a value assigned then the query will return 0 results. Is it possible that the query cannot work with only one variable out of the 2? Do I need a workaround or am i doing something wrong?
Here is the query:
SELECT T0.DocNum, T0.DocDate, T0.DocDueDate, T0.CardCode, T0.CardName, T0.Address, T0.DocTotal, T0.U_Employee, T1.firstName,T1.lastName, T0.Comments FROM OVPM T0 LEFT JOIN OHEM T1 ON T0.U_EMPLOYEE = T1.FIRSTNAME' 'T1.LASTNAME WHERE T0.DocType = 'A' AND T0.U_EMPLOYEE = [%0] AND T0.DocDate =[%1].
Thank you so much for your help,
Irina Stanca

AFAIK, at least with 'complex queries' unchecked parameter gets
some default/blank value. Therefore, you should allow default values in your
WHERE clause.
You want: WHERE T0.COL = @VAR
You write: WHERE (T0.COL = @VAR OR [logical test for @VAR is a default value])
Snippets like this may help you in finding out that default value:
-- snip --
/SELECT FROM [dbo].[OHEM] T9/
declare @VAR_EMPL as char(20)
/* WHERE */
set @VAR_EMPL = /* T9.lastName */ '[%0]'
/SELECT FROM [dbo].[OVPM] T8/
declare @VAR_DATE as char(20)
/* WHERE */
set @VAR_DATE = /* T8.DocDate */ '[%1]'
SELECT '@VAR_EMPL: ' + '|' + @VAR_EMPL + '|' + '@VAR_DATE: ' + @VAR_DATE + ' DATEDIFF: ' + cast(DATEDIFF(day, CAST('1900-01-01' as datetime), CAST(@VAR_DATE as datetime)) as varchar)
[/code]
-- snip --
Yes, it looks like the default value for dates is '1900-01-01'.
Therefore, you may want to code this way
.. WHERE (DocDate = @VAR_DATE OR DATEDIFF(day, CAST('1900-01-01' as datetime), CAST(@VAR_DATE as datetime)) > 0)
I also noticed a date-related issue that may cause problems in complex queries
if you work with dates from last century AND if your date format in B1 is YY instead of CCYY:
you enter 1907 and B1 interprets it as 2007.

Spatial Query with multiple geometries from 2 tables

Hi,
I'm using Oracle 8.1.7. I am trying to do a spatial query on two tables with multiple geometries. There are two spatial tables. One made up of points and one made up of polygons. There are 829551 rows in the table of points and 1817795 rows in the table with polygons...
I want to find all polygons where one of this points is within it...
This query is pretty intensive querying two large spatial tables against each other and so I need to find the most efficient way of running this query. I've been running variations of my query for the last two week and every time it's bombed out with various errors after 12-24 hrs processing like out of memory, out of tablespace, out of processing, invalid index etc etc etc. I need to get this query run asap... Any tips would be gratefully appreciated..
For the session running the query I've allocated 16M sort area with
ALTER SESSION SET SORT_AREA_SIZE=16777216;
Below is the query I'm running... How can I improve this please? BTW PARCEL_OVERLAPS contains the points and TP$_PARCEL_AREAS the polygons.
SELECT lu.LNU_PARCEL_ID
     FROM
          seventy.PARCEL_OVERLAPS po,
          imap_topol.TP$_PARCEL_AREAS pa,
          TP$_PARCEL_CENTROID_AREA pca,
          TDCR_LAND_UNIT lu
     WHERE
          SDO_FILTER(po.geometry, pa.area,
          'querytype=WINDOW') = TRUE and
          sdo_within_distance(po.geometry,pa.area,'distance=0')='TRUE' and
          pa.delete_date is null and
          Lu.LNU_LAND_UNIT_UNIQUE_NUM = pca.CENTROID_ID and
          pa.AREA_ID = pca.AREA_ID and
          pca.DELETE_DATE IS NULL and
          pa.DELETE_DATE IS NULL;

Albert,
Thanks for your reply and the tips you've given. The tp$_parcel_areas table will always be bigger so I've changed the order to sdo_within_distance(pa.area,po.geometry,'distance=0')='TRUE'. The requested counts for those queries are
12:26:29 [email protected]:SQL> select count(*)
13:46:22 2 from seventy.PARCEL_OVERLAPS;
COUNT(*)
612
13:48:12 [email protected]:SQL> select count(*)
13:48:17 2 from imap_topol.TP$_PARCEL_AREAS pa,
13:48:21 3 TP$_PARCEL_CENTROID_AREA pca
13:48:21 4 where pca.DELETE_DATE IS NULL
13:48:21 5 and pa.DELETE_DATE IS NULL
13:48:21 6 and pa.AREA_ID = pca.AREA_ID;
COUNT(*)
1310665
There was no reason for both filter and within_distance. I did try use the anyinteract but for some reason that does not return the desired results(I've added one id row as a test to make sure it returns desired results). Plus Oracle have recomended using the within distance for better performance..
so the explan plan for

Parrallel tables with spatial operators

I have a point in polygon script that works, but in order to speed up the creation of the point table (~175M rows) I tried adding PARALLEL 4 and /*+ PARALLEL (t,4) */ Only the parallel part is new to the create point table sql.
I used CTAS to create a point table like this:
CREATE TABLE &OUT_POINT_SCHEMA..&OUT_POINT_TABLE NOLOGGING PARALLEL 4 TABLESPACE ORDERS_02
AS
SELECT /*+ PARALLEL (t,4) */
cast(lpad(to_char(LON/1000000, '999.000000'),11) || lpad(to_char(LAT/1000000, '99.000000'),10) as varchar2(21)) ULL,
MDSYS.SDO_GEOMETRY(2001, 8307, MDSYS.SDO_POINT_TYPE(LON/1000000, LAT/1000000, NULL), NULL, NULL) GEOM
FROM
&IN_POINT_SCHEMA..&IN_POINT_TABLE
WHERE
LON is not null
GROUP BY
LON, LAT;The spatial index was created like this:
CREATE INDEX &OUT_POINT_TABLE._SIDX ON &OUT_POINT_TABLE (GEOM) INDEXTYPE IS MDSYS.SPATIAL_INDEX PARAMETERS('TABLESPACE=ORDERS_IDX WORK_TABLESPACE=ORDERS_03 LAYER_GTYPE=POINT');In theory, should the sql still work when I use, for example SDO_INSIDE? Or are there other things that I need to take into consideration? In other words, would the fact that the spatial point table was created with a parallel option impact spatial queries. When I try to monitor the process of the point in polygon sql with a check_session script (I am not a DBA) I see 4 rows with the same sql text which I assume is due to the parallel 4 parameter and I am also seeing wait_events like async descriptor resize and wait_time -1. Sorry to be so vague but I am trying to figure out if this query has a chance of finishing or if i broke it by adding the parallel option. Any guidance or suggestions would be appreciated.
Thanks,
David

Yes, spatial operators (say SDO_INSIDE) can work in parallel queries.
If you can show us your query explain plan, it will be easier to see
how SDO_INSIDE is executed.

Poor performance with Oracle Spatial when spatial query invoked remotely

Is anyone aware of any problems with Oracle Spatial (10.2.0.4 with patches 6989483 and 7003151 on Red Hat Linux 4) which might explain why a spatial query (SDO_WITHIN_DISTANCE) would perform 20 times worse when it was invoked remotely from another computer (using SQLplus) vs. invoking the very same query from the database server itself (also using SQLplus)?
Does Oracle Spatial have any known problems with servers which use SAN disk storage? That is the primary difference between a server in which I see this poor performance and another server where the performance is fine.
Thank you in advance for any thoughts you might share.

OK, that's clearer.
Are you sure it is the SQL inside the procedure that is causing the problem? To check, try extracting the SQL from inside the procedure and run it in SQLPLUS with
set autotrace on
set timing on
SELECT ....If the plans and performance are the same then it may be something inside the procedure itself.
Have you profiled the procedure? Here is an example of how to do it:
Prompt Firstly, create PL/SQL profiler table
@$ORACLE_HOME/rdbms/admin/proftab.sql
Prompt Secondly, use the profiler to gather stats on execution characteristics
DECLARE
l_run_num PLS_INTEGER := 1;
l_max_num PLS_INTEGER := 1;
v_geom    mdsys.sdo_geometry := mdsys.sdo_geometry(2002,null,null,sdo_elem_info_array(1,2,1),sdo_ordinate_array(0,0,45,45,90,0,135,45,180,0,180,-45,45,-45,0,0));
BEGIN
dbms_output.put_line('Start Profiler Result = ' || DBMS_PROFILER.START_PROFILER(run_comment => 'PARALLEL PROFILE')); -- The comment name can be anything: here it is related to the Parallel procedure I am testing.
v_geom := Parallel(v_geom,10,0.05,1); -- Put your procedure call here
dbms_output.put_line('Stop Profiler Result = ' || DBMS_PROFILER.STOP_PROFILER );
END;
SHOW ERRORS
Prompt Finally, report activity
COLUMN runid FORMAT 99999
COLUMN run_comment FORMAT A40
SELECT runid || ',' || run_date || ',' || run_comment || ',' || run_total_time
FROM plsql_profiler_runs
ORDER BY runid;
COLUMN runid       FORMAT 99999
COLUMN unit_number FORMAT 99999
COLUMN unit_type   FORMAT A20
COLUMN unit_owner FORMAT A20
COLUMN text        FORMAT A100
compute sum label 'Total_Time' of total_time on runid
break on runid skip 1
set linesize 200
SELECT u.runid || ',' ||
       u.unit_name,
       d.line#,
       d.total_occur,
       d.total_time,
       text
FROM   plsql_profiler_units u
       JOIN plsql_profiler_data d ON u.runid = d.runid
                                     AND
                                     u.unit_number = d.unit_number
       JOIN all_source als ON ( als.owner = 'CODESYS'

WHERE u.runid = (SELECT max(runid) FROM plsql_profiler_runs)
ORDER BY d.total_time desc;Run the profiler in both environments and see if you can see where the slowdown exists.

Simple spatial query with different SRID

Can anyone help me with just a real simple spatial query with different SRID.
Here is the error i get when i perform the query:
AND SDO_RELATE(A.geometrie_point, B.GEOMETRIE_POLYGONE, 'mask=anyinteract querytype=WINDOW') = 'TRUE'
ERROR at line 4:
ORA-00604: error occurred at recursive SQL level 1
ORA-13207: incorrect use of the [IN COMPATIBLE BOUNDS in SDO_RELATE] operator
ORA-06512: at "MDSYS.SDO_INDEX_METHOD", line 84
ORA-06512: at line 4

Hi,
I am using 8.1.7.2 and i have the lattest spatial patch.
From the start i had different SRID. The only thing i changed was the bounds of the coordinate system.
I reset my bounds of the coordinate system with SRID 8307 to -180,
180 in X (longitude), and -90,90 in Y (latitude) to see if the query window geometry
(geom2) will be transformed to the coordinate system of the layer geometries (geom1)
Her is the content of the user_sdo_geom_metadata :
GIS_PCP GEOMETRIE_POINT
SDO_DIM_ARRAY(SDO_DIM_ELEMENT('X', -5800000, 3600000, .00000005), SDO_DIM_ELEMENT('Y', 3516000, 6000000, .00000005))
82227
GIS_TEST GEOMETRIE_POLYGONE
SDO_DIM_ARRAY(SDO_DIM_ELEMENT('X', -180, 180, .00000005), SDO_DIM_ELEMENT('Y', -90, 90, .00000005))
8307
Here is my query :
select /*+ ordered */ A.no_point
from gis_pcp A, gis_test B
WHERE SDO_RELATE(A.geometrie_POINT, B.GEOMETRIE_POLYGONE, 'mask=anyinteract querytype=WINDOW') = 'TRUE';
Here is my result :
WHERE SDO_RELATE(A.geometrie_POINT, B.GEOMETRIE_POLYGONE, 'mask=anyinteract querytype=WINDOW') = 'TRUE'
ERROR at line 3:
ORA-00604: error occurred at recursive SQL level 1
ORA-13207: incorrect use of the [IN COMPATIBLE BOUNDS in SDO_RELATE] operator
ORA-06512: at "MDSYS.SDO_INDEX_METHOD", line 84
ORA-06512: at line 4
If i change the bounds of GIS_TEST to the exact bouns of GIS_PCP then i dont have the error message above and i have correct results. Do i have the adjust the bounds of every layer to fit the biggest bound?

ODCI error with spatial operators

Hi group,
I get ODCI errors with spatial operators SDO_RELATE, SDO_FILTER and SDO_WITHIN_DISTANCE (not SDO_NN) called from JDBC (Java 1.2.2).
For example:
SELECT A.gid FROM FeatureTable1 A, FeatureTable1 B WHERE B.gid = 3 AND SDO_RELATE(A.Geometry, B.Geometry, 'mask=ANYINTERACT querytype = WINDOW') = 'TRUE';
Displays the error
ORA-29902: error in executing ODCIIndexStart() routine
Other functions such as SDO_AREA, SDO_NN work fine, though.
Both feature tables where populated with the SDOAPI toolkit and indexed using a fixed index.
I use a default full install of Oracle 8.1.6 on Linux RedHat 6.2.
What's wrong? Do I need to install anything else on the server?
Thanks for any advice.

Hi Dan,
There are several errors in the SampleNewToSDO.java sample. The outer polygons should be anti-clockwise, the inner polygons should be clockwise. Now that this is fixed, polygons (with or without inner polygons) do pass the validation test, but multipolygons do not.
What's wrong with this multipolygon:
double outerOrdArray1[] = {310, 310, 320, 310, 320, 320, 310, 320, 310, 310};
LineString outerLineString1 = gF.createLineString(outerOrdArray1);
double innerOrdArray1[] = {311, 311, 311, 319, 319, 319, 319, 311, 311, 311};
LineString innerLineStrings1[] = new LineString[1];
innerLineStrings1[0] = gF.createLineString(innerOrdArray1);
collection[0] = gF.createPolygon((LineString)outerLineString1,
(LineString[])innerLineStrings1);
double outerOrdArray2[] = {410, 410, 420, 410, 420, 420, 410, 420, 410, 410};
LineString outerLineString2 = gF.createLineString(outerOrdArray2);
double innerOrdArray2[] = {411, 411, 411, 419, 419, 419, 419, 411, 411, 411};
LineString innerLineStrings2[] = new LineString[1];
innerLineStrings2[0] = gF.createLineString(innerOrdArray2);
collection[1] = gF.createPolygon((LineString)outerLineString2,
(LineString[])innerLineStrings2);
geom = gF.createGeometryCollection(collection);
Note that the sdoapi java library does not detect anything wrong with the geometry (isValid() returns true even when the order of vertices is wrong).
Heterogenous collections are OK. Only multipolgons are wrong. To check whether the multipolygon was correctly stored in the table, I exported the table to XML using the SampleSDOtoXML.java sample. It looks good:
<MultiPolygon>
<Polygon name="0" srsName="0">
<LineString name="0" srsName="0"> <CList>310.0,310.0 320.0,310.0 320.0,320.0 310.0,320.0 310.0,310.0</CList> </LineString>
<LineString name="0" srsName="0"> <CList>311.0,311.0 311.0,319.0 319.0,319.0 319.0,311.0 311.0,311.0</CList> </LineString>
</Polygon>
<Polygon name="0" srsName="0">
<LineString name="0" srsName="0"> <CList>410.0,410.0 420.0,410.0 420.0,420.0 410.0,420.0 410.0,410.0</CList> </LineString>
<LineString name="0" srsName="0"> <CList>411.0,411.0 411.0,419.0 419.0,419.0 419.0,411.0 411.0,411.0</CList> </LineString>
</Polygon>
</MultiPolygon>
So why does SDO_GEOM.VALIDATE_GEOMETRY return 13050? Is there a special vertex ordering rule for multipolygons?
Thanks,
Jean-Pierre
