ODP.NET :: Null Values In (ref) Attributes - C# Odp Type Factory?
Nov 22, 2012I'm using the odp.net type factory (class IOracleCustomType and the specific annotations...) to map udts to c# classes.By now I had no problems with it, because I've never used "ref" attributes within the udts.Now I need the use of "ref" attributes within udts but it seems that the odp factory cannot handle those references.
For example:_*
A Simple Type:
create or replace type bookcontent_t force as object (
id number(20)
, name varchar2(1000)
);*And a collection with references to objects of this type:*
create or replace type fms_bookcontent_ref_cln force as table of *ref* bookcontent_t;The c# class is generated by odp.net.
When I retrieve data by using odp.net I get a collection with the correct number of elements but the values are null.What can I do to solve this problem with "ref" attributes/lists? How can I get the referenced object instances?

PL/SQL :: How To Check Particular Attributes Exists Or Not In XML Tag
Aug 14, 2012As per the earlier post,I am able to parse now.
i have also another concern as per below xml file.
My requirement is to identify perticular node ,whose having PriorValue attribute present in <pi:the Actual_Comp_Change> tag,those record should return.
<?xml version="1.0" encoding="UTF-8"?>
<pi:Extract_Employees xmlns:pi="urn:com.workday/picof">
<pi:Employee>
<pi:Employee_ID>1100</pi:Employee_ID>
[Code]....
OUTPUT:
EmployeeID_ Name JobTitle_ Grade ActualComp_Change_
1100 Surana Intern - Master¿s A 500000
1000 roy Intern - Master¿s B 216000
1000 roy Intern - Master¿s 00 266000
But my requirement is to display only those employeeID ,where Actual_Comp_Change tag having PriorValue attribute.
The required OutPUT should be :
EmployeeID_ Name JobTitle_ Grade ActualComp_Change_
1100 Surana Intern - Master¿s A 500000
is there any possibility to use ExistNode() function to the above quer or is there any alternative solution.
SQL & PL/SQL :: Select Some Attributes From That Object In Same Query
Oct 25, 2013He had created an object type and wanted to populate it in a query. So far so good. But then he wanted to select some attributes from that object in the same query. Basically, he wanted to do something like this:
With his_view
As
( select object_type( attr1, attr2) theobj
From his_table
Where ...
)
Select theobj.attr1
From his_view
But somehow he was hitting ORA-00904: "THEOBJ"."ATTR1": invalid identifier over and over again.Here's a test script:

PL/SQL :: Oracle Objects - Insert Particular Attributes
Apr 4, 2013I'm using the below data base version
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production.
I have created a pl sql type as object with five attributes as below.Now im trying to insert only 3 attributes with the attribute names ( As like insert into statement with column names).
Create type address_test as object (
Streetno varchar2(20),

Is that possible to use attribute names in the insert statement of column object type ?
SQL & PL/SQL :: Counting NULL Vs NON-NULL In A GROUP BY Clause
Jun 21, 2010I am running a GROUP BY query on a few columns of enumerated data like:
select count(*), Condition, Size
group by Condition, Size;
COUNT(*) CONDITION SIZE
-------- ---------- --------
3 MINT L
2 FAIR L
4 FAIR M
1 MINT S
Well, let's say I also have a timestamp field in the database. I cannot run a group by with that involved because the time is recorded to the milisec and is unique for every record. Instead, I want to include this in my group by function based on whether or not it is NULL.
For example:
COUNT(*) CONDITION SIZE SOLDDATE
-------- ---------- -------- ----------
3 MINT L ISNULL
2 FAIR L NOTNULL
2 FAIR M NOTNULL
2 FAIR M ISNULL
1 MINT S ISNULL

SQL & PL/SQL :: Create Nested Query Within Select Of Attributes
Dec 21, 2011I'm trying to create a sort of nested-query within my select of attributes . i.e.
select A.a,
B.b,
(select count(C.*)
from C
where C. = B.d
group by C.y)
from A a,
B b
where A.d = B.d
and ...
Over-simplifying my query:
select B.desc "Location",
F.desc "Source",
A.amt "Amount",
sum(G.G_CNT) "No. Units",
c.desc "Status"
[code]....
I need to incorporate a count of the number of units from TableG that have a certain status. I tried the following but when I tried to run it, I get an error saying that it's not a Group By expression -the red part is highlighted in TOAD.
select B.desc "Location",
F.desc "Source",
A.amt "Amount",
sum(G.G_CNT) "No. Units",
(select count(*)
from TableG G2
where G2.D_ID = D.ID
and G2.status = 10
group by G2.D_ID)"Count",
c.desc "Status"
[code]....
Any thoughts how I can incorporate a query in my select of attributes?how to Group By something.

SQL & PL/SQL :: Unique Null And Multiple Non-null
Oct 24, 2013create table test
(
id int ,
dat date
)
/
I want to implement a business rule such as we have for each id at most 1 dat null. So, I've created this unique index on test.
create unique index x_only_one_dat_cess_null on test(id, case when dat_cess is null then 'NULL' else to_char(dat_cess, 'dd/mm/yyyy') end);
insert into test values (1, sysdate);
insert into test values (1, sysdate - 1);
insert into test values (1, null);
insert into test values (1, null);
-- -----
insert into test values (2, sysdate);
insert into test values (2, sysdate - 1);
insert into test values (2, null);
The 4th insert will cause an error and this is what I wanted to implement. OK. Now the problem is that for non-null values of dat, we can't have data like this
iddat
------------
124/10/2013
123/10/2013
123/10/2013
1
because of the unique index (the 2nd and the 3rd row are equal). So just for learning purposes, how could we allow at most one null value of dat and allow duplicates for non-null values of dat.

SQL & PL/SQL :: Access Attributes Of Objects Of Nested Table In Member Function Of Oracle Database
Nov 17, 2011I have created two types and a list of the first type:
create type type1;
/
create type type1_list as table of ref type1;
/
create type type2;
/
I have now just created the two types as follows:
create type type1 as object(
id# number
);
/
create type type2 as object(
attribute1 type1_list,
MEMBER FUNCTION function1 RETURN NUMBER
);
/
Ok, I've created the tables (I don't know if it's necessary to point out my problem)
CREATE TABLE type1_table OF type1;
/
CREATE TABLE type2_table OF type2
NESTED TABLE attribute1 STORE AS nested_type1_list_table;
/
And what I wanted to do now is to implement the member function1 and check something of the attributes of type1 in the list of attribute1... And that's where my question occurs, how does it work, I can't figure it out. I tried something like this:
Quote:
create or replace
TYPE BODY type2 AS
MEMBER FUNCTION function1 RETURN NUMBER AS
[Code]....
But I don't get the right way, it doesn't work
Data Guard :: ARCH Wait On SENDREQ While Configured With LGWR ASYNC Attributes?
Oct 5, 2010In statspack I find a lot of wait events "ARCH wait on SENDREQ". The database is configured with the LGWR ASYNC attribute. In the documentation I can read that the "ARCH wait"-events may happen in case the database is configured with the ARCH attribute.How is it possible I get these "ARCH wait"-envents and do these wait events have any effect on the "on line" performance of the database? Is it possible that a user that saves data in the database has to wait for thest "ARCH wait"-events?

SQL & PL/SQL :: Trigger With Null Old Value
Feb 15, 2011I have the following problem.
I have a trigger "before update" that change some values, including a timestamp column. My sql code does an update using the "returning clause" to get the values changed by the trigger. The problem is:
When I do an "update [...] returning timestamp_field", this timestamp_field has the old value equals to null (in the trigger). And, this field in the table is not null. This problem not occurs with the others fields of type number, varchar... only with the timestamp field.
Here are the code to simulate this problem:
--Table
create table TB_TEST
(
ID NUMBER(10) not null,
FLAG NUMBER(10) not null,
TAG VARCHAR2(16) not null,
TS_ATU_DTR TIMESTAMP(9) not null
);
[Code]..
Testing
exec test1;
select * from textolog order by data, texto;
Output:

"old.TS_ATU_DTR=, " Isn't it right?????
Why the other fields aren't null?
I need the "old.TS_ATU_DTR" to use in my other trigger to compare timestamps, how can I get it?
Or, is there a patch for this problem?
