4.0 EA1 - Cannot select from table with xmltype

Hi,
I have the following table. When doing a select * from horus_owner.horus_objects nothing is shown. This could be reproduced with both 10g and 11g on the database-side.

Not sure if this helps, but I was trying to come up with some test cases myself and I noticed some strange behavior. 4 simple test cases:
SELECT XMLTYPE('<OUTER><INNER>TEST</INNER></OUTER>') FROM DUAL;
SELECT XMLELEMENT("OUTER", XMLELEMENT("INNER", 'TEST')) FROM DUAL;
SELECT XMLELEMENT("OUTER", XMLAGG(XMLFOREST('TEST' "INNER"))) FROM DUAL;
SELECT XMLQUERY('/OUTER' PASSING XMLTYPE('<OUTER><INNER>TEST</INNER></OUTER>') RETURNING CONTENT) FROM DUAL;
1 and 2 return the xml string in the result grid column. 3 and 4 return (XMLTYPE) with no data in the pop-up editor when double clicking the result. I changed #3 to:
SELECT XMLELEMENT("OUTER", XMLFOREST('TEST' "INNER")) FROM DUAL;
and it returns the XML string.
I used undo to revert back to my original #3 and it started showing the XML string instead of (XMLTYPE) previously observed.
I changed my connection to another schema, ran #3 again, and it went back to (XMLTYPE). I tried to recreate the same behavior using the 2nd schema, but I was unable to get to show the XML string.
In any test case where I was getting the (XMLTYPE), I was not able to see data in the pop-up editor.

Insert problem using a SELECT from table with a index by function TRUNC

I came across this problem when trying to insert from a select statement, the select returns the correct results however when trying to insert the results into a table, the results differ. I have found a work around by forcing an order by on the select, but surely this is an Oracle bug as how can the select statements value differ from the insert?
Platform: Windows Server 2008 R2
Oracle 11.2.3 Enterprise edition
(I have not tried to replicate this on other versions)
Here are the scripts to create the two tables and source data:
CREATE TABLE source_data
ID                 NUMBER(2),
COUNT_DATE      DATE
CREATE INDEX IN_SOURCE_DATA ON SOURCE_DATA (TRUNC(count_date, 'MM'));
INSERT INTO source_data VALUES (1, TO_DATE('20120101', 'YYYYMMDD'));
INSERT INTO source_data VALUES (1, TO_DATE('20120102', 'YYYYMMDD'));
INSERT INTO source_data VALUES (1, TO_DATE('20120103', 'YYYYMMDD'));
INSERT INTO source_data VALUES (1, TO_DATE('20120201', 'YYYYMMDD'));
INSERT INTO source_data VALUES (1, TO_DATE('20120202', 'YYYYMMDD'));
INSERT INTO source_data VALUES (1, TO_DATE('20120203', 'YYYYMMDD'));
INSERT INTO source_data VALUES (1, TO_DATE('20120301', 'YYYYMMDD'));
INSERT INTO source_data VALUES (1, TO_DATE('20120302', 'YYYYMMDD'));
INSERT INTO source_data VALUES (1, TO_DATE('20120303', 'YYYYMMDD'));
CREATE TABLE result_data
ID                 NUMBER(2),
COUNT_DATE      DATE
);Now run the select statement:
SELECT id, TRUNC(count_date, 'MM')
FROM source_data
GROUP BY id, TRUNC(count_date, 'MM')You should get the following:
1     2012/02/01
1     2012/03/01
1     2012/01/01Now insert into the results table:
INSERT INTO result_data
SELECT id, TRUNC(count_date, 'MM')
FROM source_data
GROUP BY id, TRUNC(count_date, 'MM');Select from that table and you get:
1     2012/03/01
1     2012/03/01
1     2012/03/01The most recent month is repeated for each row.
Truncate your table and insert with the following statement and the results should now be correct:
INSERT INTO result_data
SELECT id, TRUNC(count_date, 'MM')
FROM source_data
GROUP BY id, TRUNC(count_date, 'MM')
ORDER BY 1, 2;If anyone has encountered this behavior before could you please let me know, I can't see that I am making a mistake as the selects results are correct they should not differ from what is being inserted.

Hi,
welcome to the forum. I cannot reproduce the same behavior.
Could you please post the SQLPlus output while executing all commands, like it has been done by S10390?
Also post the output of the following command:
SELECT * FROM v$version;When you put some code or output please enclose it between two lines starting with {noformat}{noformat}
i.e.:
{noformat}{noformat}
SELECT ...
{noformat}{noformat}
Formatted code is easier to read.

Issue with extractvalue from table with XMLTYPE column.

I'm sure there is a simple answer but I am having problems
retrieving data from an xmltype column type.
I have two tables
descr dab_xmlName
TABLE of XMLTYPE
descr dab_testName
A NUMBER
AB NUMBER
DATA CLOB
DATA2 VARCHAR2(1600)
MYXML XMLTYPE
I have inserted the Oracle example XML purchaseOrder.xml into both dab_xml
and the myxml column in dab_test.
When I run the following:
SELECT extractvalue(OBJECT_VALUE, '/PurchaseOrder/Reference')
FROM dab_xml;
SBELL-2002100912333601PDT is returned
When I run this:
SELECT extractvalue(OBJECT_VALUE, '/PurchaseOrder/Reference')
FROM (select myxml from dab_test);
ERROR at line 1:
ORA-00904: "OBJECT_VALUE": invalid identifier
Why are the two different?
Any help will be appreciated.
Regards,
David

In short you want
SELECT extractvalue(myxml, '/PurchaseOrder/Reference')
FROM dab_test;This difference is that for dab_xml, there are no columns defined for the table, therefore you are [OBJECT_VALUE|http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/pseudocolumns006.htm#sthref830] as an alias for a non existent column.
With dab_test, you have a column that contains the XML so you need to use that column name instead of OBJECT_VALUE.

Problem deleting from table with xmltype column

Hi,
Using a standard, simple screen (generated from JHeadstart), I don't seem to be able to delete from a table including an xmltype column. I have tried it even with a very simple mock table with only one column, an xmltype column, and every time I check the "delete" box and click "save", I get the following error:
oracle.jbo.RowInconsistentException: JBO-25014: Another user has changed the row with primary key oracle.jbo.Key[33 ].
I have tried this in the JDeveloper application module tester too and the result is the same.
Is it possible to delete a row from a table with an xmltype column? Am I doing something wrong? Is there something special needs done?
As I say, I did this with a one-xmltype-column table using the "Business Components from Tables" wizard, accepting all the defaults.
Thanks,
Darren

In short you want
SELECT extractvalue(myxml, '/PurchaseOrder/Reference')
FROM dab_test;This difference is that for dab_xml, there are no columns defined for the table, therefore you are [OBJECT_VALUE|http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/pseudocolumns006.htm#sthref830] as an alias for a non existent column.

How do you delete records from table with data in a select option

delete * from table
where field in s_select_option.
endif.

Be careful though. If select option is emty, you will delete the entire table.

Select * from table not working with Oracle OBDC driver

Hello,
In our web development we have been using the MS ODBC for Oracle
driver to connect to our Oracle db. We decided to try the
Oracle ODBC driver because it supports the commandTimeout
property in ASP which the MS driver does not. The problem I'm
running into now is that all of our select * from table
statements appear not to be working. The Oracle ODBC driver
version we are using is ver 8.00.05.00. Is there something that
I'm not doing properly? If I take the same select * from table
statement and name the columns, I dont get any error. Otherwise
I'm getting a Subscript out of range error. It seems strange to
me that this driver would not support a select * from table
statement (which I''m told is the case by another developer
here).
Is there something I'm missing?
Thanks,
Pete

I'm positive I have a connection. Otherwise I wouldn't get a
response when I name the columns instead of using *.
There must be something else that I'm missing or doing wrong.
I've actually been looking into alternative ODBC drivers to see
if I have the same problems but none that I have found support
commandTimeout.
Any other ideas?

Problem in displaying data onto Form after selecting from table.

Hi there,
I keep hitting this error when I tried to display the data after the selection from table. Using backing beans w data control to do it
Err: java.lang.ClassCastException: java.util.Collections$SingletonList cannot be cast to java.lang.Integer
Table used ArrayList to retrieve out the wanted data. E.g uses A object
To display: selected data to retrieve the selected row to display as a read-only form layout below the table. E.g. need to get A.getName() to match with B object B.getName() then uses the B object to retrieve out the data.
Anyone know how to do it?

Hi

Html form for select * from table a

Hi all,
I m looking for report on header/footer part from one apex pages
which will display context from table a, like sql statement
select * from table a, written in html.
Is any examples in java script/html select from tables
(and same insert into table A (...) select * from table b)
thanks,
Gordan

Hello Gordan,
Do you want to show the whole report or just some data of it?
If it's for ex just the name and address you could create two items and have a process or computation to fill it with your select statement.
If it's the whole report, just create the report and put it in for ex. Region 1. In your page template you can specify that Region 1 needs to come into the footer.

Dimitri

How do I do SELECT * FROM TABLE WHERE KEY IN ({list})?

The title says it all really.
Is there a reasonable performant way to perform the query
SELECT * FROM TABLE WHERE KEY IN ({list})where {list} is String []?
I am currently creating a PreparedStatement with a for loop like this StringBuffer sb = new StringBuffer ("SELECT * FROM TABLE WHERE ID IN (");
for (int ii=0;ii<keys.length;ii++) {
sb.append (keys [ii]);
if (ii != keys.length-1) sb.append (",");
sb.append (")");but this means that the prepared statement is created each time I call my method and so I'm not sure that the optimizer will find it easy to cope with. Is there a construction that I'm missing along the lines of SELECT * FROM TABLE WHERE KEY = ? where I can create the PreparedStatement once and just call setObject or something on it when the values in {list} change?

but this means that the prepared statement is created
each time I call my method and so I'm not sure that
the optimizer will find it easy to cope with.You are right, the optimizer won't find that easy to deal with (presuming that is even relevant for your driver/database.) But most optimizers won't do anything with statements that change and that is what you are doing.
You could create several prepared statements which have a common number of bind variables. For example 10 statements with from 1 to 10 bind values. This will work if most of the queries use those.

Performace Which is better ? : Bapi inside a loop OR Select from Tables

Hi Gurus,
I have a report which displays purchase info records.
If I am selecting from tables i need to use EINA, EINE, EORD and some other tables.
There is a BAPI which gets all purchase info records specific to a vendor , material , purchasing organisation.
QUESTION: Performace wise which is the better Approach, either selecting from tables or BAPI for Purchase info records
Regards
Avi.

Whether it using BAPI or select. you need to check the performance. If you have full key for these tables EINA, EINE, EORD then mak a select outside of the loop and within loop use READ TABLE statement with binary search. of if you want multiple records within loop then use loop insdie loop.
Your final objective is to minimise the database hits . If you use bapi inside loop then your database hits will be more
select from EINA
select from EINE
select from EORD
loop at itab,
read table EINA
read table EINE
read table EORD
endloop

Problems with retrieving data from tables with 240 and more records

Hi,
I've been connecting to Oracle 11g Server (not sure exact version) using Oracle 10.1.0 Client and O10 Oracle 10g driver. Everything was ok.
I installed Oracle 11.2.0 Client and I started to have problems with retrieving data from tables.
First I used the same connection string, driver and so on (O10 Oracle 10g) then I tried ORA Oracle but with no luck. The result is like this:
I'm able to connect to database. I'm able to retrieve data but from small tables (e.g. with 110 records it works perfectly using both O10 and ORA drivers). When I try to retrieve data from tables with like 240 and more records retrieval simply hangs (nothing happens at all - no error, no timeout). Application seems to hang forever.
I'm using Powerbuilder to connect to Database (either PB10.5 using O10 driver or PB12 using ORA driver). I used DBTrace, so I see that query hangs on the first FETCH.
So for the retrievals that hang I have something like:
(3260008): BIND SELECT OUTPUT BUFFER (DataWindow):(DBI_SELBIND) (0.186 MS / 18978.709 MS)
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=0
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=1
(3260008): ,len=160,type=DECIMAL,pbt=4,dbt=0,ct=0,prec=0,scale=0
(3260008): EXECUTE:(DBI_DW_EXECUTE) (192.982 MS / 19171.691 MS)
(3260008): FETCH NEXT:(DBI_FETCHNEXT)
and this is the last line,
while for retrievals that end, I have FETCH producing time, data in buffer and moving to the next Fetch until all data is retrieved
On the side note, I have no problems with retrieving data either by SQL Developer or DbVisualizer.
Problems started when I installed 11.2.0 Client. Even if I want to use 10.0.1 Client, the same problem occurs. So I guess something from 11.2.0 overrides 10.0.1 settings.
I will appreciate any comments/hints/help.
Thank you very much.

Installing 11g client changed something that even using old 10g client (which I still have installed) fails to work. The same problem occur no matter I'm using 10g or 11g client now. Powerbuilder hangs on retrieving tables with more than like 240 records.

Expression Framework / SELECT * FROM TABLE(CAST(...

Hello!
Is it possible to build the following with Toplink Expression Framework?
Example:
CREATE TYPE TY_OB_TEST AS OBJECT
( SYSTOP_NR NUMBER(5,0)
SYS_NR NUMBER(5,0)
IM_SYS_NAME VARCHAR2(80) ) ;
CREATE TYPE TY_TB_TEST AS TABLE OF TY_OB_TEST;
Package1.FUNCTION1 returns Type TY_TB_TEST.
SQL:
select * from TABLE(CAST(PACKAGE1.FUNCTION1(42)) AS TY_TB_TEST ));
thank you!

Nope, just use SQL.

Insert into table a (select * from table b) - need pk?

Hi there.
I'm going to insert into table FINAL (select * from table STAGING) - same structure but in STAGING the ID column has nulls.
Do I need to provide the ID (primary key) for table FINAL or will it get created based on sequence/trigger?
If I were doing this in a loop I'd get the next val from the sequence but on a simple insert, I'm curious.
thanks!

hmm.. what is ?
it didn't like it.
