Select from nested table

Hi,
I create following types and table:
CREATE OR REPLACE TYPE obj_query AS OBJECT
(emp_id NUMBER(6)
,emp_first VARCHAR2(20)
,emp_last VARCHAR2(25));
CREATE OR REPLACE TYPE tab_query AS TABLE OF obj_query;
CREATE TABLE queryEmp
(id_row NUMBER
,beginTrans VARCHAR2(15)
,queryA VARCHAR2(100)
,resultEmp tab_query)
NESTED TABLE resultEmp
STORE AS nested_queryEmp;
I would like the output of the table queryEmp like this:
id_row beginTrans queryA emp_id emp_first emp_last
1 15:00 Select1 100 Joe King
101 John Queen
2 15:10 Select2 100 Leo King
101 Mett Queen
But Can I get this result with only SQL SELECT statement from this table?
I don't want to use PL/SQL, only SELECT in SQL*Plus.
Thank you
I'm sorry but output looks so bad.
So, I want to get the one row of id_row, beginTrans, queryA and all rows of nested table dmlStats to this "main" row and so on.
But not in PL/SQL
I hope, you understand me.
Thanks

Obtain info from nested table in function?

Oracle9i 9.2.0.1.0/Windows 2000
I'd like to obtain an ID from a nested table object in order to insert it into an ID field (outside the nested table I'm getting it from). I've got a function that lets me get a foreign key ID from one other table ('objtarget'); but it isn't nested:
CREATE FUNCTION oeln.get_obj_id(
     obj_type IN oeln.objtarget.objecttarget%type
RETURN oeln.objtarget.obj_id%type
IS id_type oeln.objtarget.obj_id%type;
BEGIN
SELECT obj_id INTO id_type
FROM oeln.objtarget
WHERE oeln.objtarget.objecttarget = obj_type;
RETURN(id_type);
END;
SELECT obj_id
FROM oeln.objtarget
WHERE obj_id = get_obj_id('');
I'm getting compilation errors on functions to obtain ID's from nested tables instead. I've got the table 'opt' (includes the fields 'opt_id' & 'optics'). The 'optics' field in opt is of type o_tab(o_ty), including the field 'optinfo'. I'd like to get the opt_id out of the opt table, from input I obtain for the optinfo field: i.e.,
SELECT opt_id
FROM oeln.opt
WHERE opt_id = get_opt_id('');
In other words, I'd like to get opt_id from the opt table like I get obj_id from the objtarget table; but instead of looking it up by objecttarget I've got to look it up by optinfo, a field in a nested table object in the opt table itself. I've only gotten compilation errors on functions in order to do this. Is this an option?

Retrieve data from nested tables

Hi All,
I have big trouble to retrieve data from nested tables..
From java code developer are passing struct data type to Oracle procedure.. So equal data type in oracle has been created as created as object
CREATE OR REPLACE TYPE TXNDATA AS OBJECT
TRAN_ID            NUMBER             ,
EVENT_ID                   NUMBER             ,
EVENT_CD                   VARCHAR2(10 BYTE))and create a procedure which has a IN parameter as TXNDATA
now i need to retrieve the column data's through SELECT clause such as
TYPE Proc_txn IS TABLE OF TXNJOURNALDATA;
EVENT_JOURNAL_SEQ Proc_txn;
select * from table(cast(EVENT_JOURNAL_SEQ));but above SQL will give all column data's but i need to retrieve only 2 column values such as
select EVENT_ID , EVENT_CD from table(cast(EVENT_JOURNAL_SEQ))how can i achieve the above result set?
Thanks & Regards

How to populate a table based on a row selection from another table.

Hi, i just started to use ADF BC and Faces. Could some one help me or point me a solution on the following scenario .
By using a search component , a table is being displayed as a search result. If i select any row in the resulted table , i need to populate an another table at the bottom of the same page from another view. These two tables are related by primary key . May i know how to populate a table based on a row selection from another table. Thanks
ganesh

I understand your requirement and the tutorial doesn't talk about Association between the views so that you can create a Master-Detail or in DB parlance, a Parent-Child relationship.
I will assume that we are dealing with two entities here: Department and Employees where a particular Department has many Employees and hence a Parent-Child relationship.
Firstly, you need to create an Association between the two Entities - Department and Employees. You can do that by right clicking on the model's entity and then associating the two entities with the appropriate key say, DepartmentId.
Once you have done that, you need to link the two entities in the View section with this Association that you created. Then go to AppModule and make sure that in the Available View Objects: 'EmployeesView' appears under 'DepartmentView' as "EmployeesView via <link you created>". Shuttle the 'DepartmentView' to the right, Data Model and then shuttle
"EmployeesView via <link you created>" to the right, Data Model under 'DepartmentView'.
This will then be reflected in your Data Controls. After that, you simply would have to drag this View into your page as a Master-Detail form...and then when you run this page, any row selected in the Master table, would display the data in the Detail table.
Also, refer to this link: [Master-Detail|http://baigsorcl.blogspot.com/2010/03/creating-master-detail-form-in-adf.html]
Hope this helps.

How to do a SELECT from different tables into an internal table?

How to do a SELECT from different tables into an internal table?
I want to select data from MARA, MARC and ZPERSON and populate my ITAB_FINAL
REPORT zinternal_table.
TABLES:
mara,
marc,
zperson.
TYPES:
BEGIN OF str_table1,
v_name LIKE zperson-zname,
v_matnr LIKE marc-matnr,
v_emarc LIKE marc-emarc,
v_werks_d LIKE marc-werks_d,
v_dstat LIKE marc-dstat,
END OF str_table,
i_table1 TYPE STANDARD TABLE OF str_table1.
DATA:
BEGIN OF str_table2,
v_mandt LIKE mara-mandt,
v_ernam LIKE mara-ernam,
v_laeda LIKE mara-laeda,
END OF str_table2,
itab_final LIKE STANDARD TABLE OF str_table2.

first find the link between mara , marc and zperson , if u have link to 3 tables then u can jus write a join and populate the table u want ( thats final table with all the fields).
u defenitely have alink between mara and marc so join them and retrieve all data into one internal table.
then for all the entries in that internal table retrieve data from zperson into another internal table.
then loop at one internal table
read another internal table where key equals in both the tables.
finally assign fileds if sy-subrc = 0.
gs_finaltable-matnr = gs_table-matnr
etc...
and finally append gs_finaltable to gt_finaltable.
there u go ur final table has all the data u want.
regards

How to avoid ORA-3113 when selecting from XMLTYPE table

Hi,
If I register an XML-schema, Oracle automatically creates a table xxxxxx_tab of XMLTYPE. (I use Oracle 9.2.0.1)
When I do a DESCRIBE or a SELECT from this table I get the error: 'ORA-03113:
end-of-file on communication channel' and my connection is dropped.
I opened a TAR for this and Oracle says: 'It is an internal bug so cannot be viewed in metalink. This is fixed in release 10i.' (do they mean oracle DB rel 10i, or a new version of XDK?)
I saw an example in Oracle Magazine (Jan
2003) "Make XML Native and Relative" about Oracle 9i Rel 2 and XML. As you can see in codeListing 7, the author also does a select from such a
table (CD331_tab): Why doesn't he have any problems?
Is there a workaround for this bug? What's the purpose of being able to automatically upload XML-data to a registered schema if you can't do a select of the data?
Thank you!

It appears that the XML Schema is not entirely valid. Specifically, the definition of element "DeviceCategory" has two definitions of element "Audio" appearing within a <choice> model i.e. something like :
<element name="DeviceCategory">
<choice>
<sequence>
<element name="Audio">
</sequence>
<sequence>
<element name="Audio">
</sequence>
</choice>
This is disallowed by XML Schema spec per. the Unique Particle Attribution Constraint. The general idea is that a XML Schema describes a determinstic content model i.e. schema processor can always unambiguosly determine the matching declaration when it encounters an element. However that's not the case with the declaration above. On encoutering "Audio", it could match either the first or the second declaration of the element. Hence the error.
You will have to rework the schema to avoid this constraint. One mechanism could be to define complexType and their restrictions.

Select from a table from other schema

Hi,
I want to make a select from a table how is into other Schema and into other instance.
form example, if I have _2 schemas (in diferent instances)_:
SCHEMA1 =
*(DESCRIPTION =*
*(ADDRESS =*
*(PROTOCOL = TCP)*
*(HOST = XXX.XXX.XXX.XX1)*
*(PORT = 1560)*
*(CONNECT_DATA =*
*(SERVER = DEDICATED)*
*(SERVICE_NAME = SCHEMA1)*
SCHEMA2 =
*(DESCRIPTION =*
*(ADDRESS =*
*(PROTOCOL = TCP)*
*(HOST = XXX.XXX.XXX.XX2)*
*(PORT = 1560)*
*(CONNECT_DATA =*
*(SERVER = DEDICATED)*
*(SERVICE_NAME = SCHEMA2)*
and into SCHEMA2 there is a table TABLE_A.
If I`m connected into SCHEMA1:
how can I do to make a select from the TABLE_A?
thanks very much.

1) Referring to an entry in the tnsnames.ora file as a "schema" as you have here with schema1 and schema2 is likely to be confusing. You have multiple schemas in the same database-- in this case, you appear to be trying to query tables in a different database. If we try to answer using your TNS aliases "schema1" and "schema2", there is likely to be a great deal of confusion between schemas/ databases/ and TNS aliases. So I will assume that your tnsnames.ora file actually reads
TNS_ALIAS1 =
(DESCRIPTION =
    (ADDRESS =
      (PROTOCOL = TCP)
      (HOST = HOST1)
      (PORT = 1560)
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = DB1)
TNS_ALIAS2 =
(DESCRIPTION =
    (ADDRESS =
      (PROTOCOL = TCP)
      (HOST = HOST2)
      (PORT = 1560)
(CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = DB2)
)2) Given the TNS aliases above, assuming that we are talking about the tnsnames.ora file on HOST1, you would need to create a database link from DB1 to DB2. You can either specify a fixed username and password for the database link or you can specify that the connection happens as the current user (which assumes that the passwords are synchronized between the databases).
CREATE DATABASE LINK to_db2
CONNECT TO username_on_db2
IDENTIFIED BY password_on_db2
USING 'TNS_ALIAS2'3) Assuming the database link is in place

order by "DBSID_NAME";
insert into "DBSID_LOOKUP" ("SIDLOOKUP_ID", "SERVERLOOKUP_ID")
values(tempsid, temphostsid);
END;
run;
I get the error ....

1. DECLARE
2. tempsid number;

okay ... I tried a different way ...

Selecting from two tables and confirming from them despites they not relate

Please I need a query to select from two tables that are not related to each other.
I also want to confirm data's as in verify wether what the user has entered is in accordance with what is in the tables
Examples
the first table is named "Card" and the second table is named "Student_Details"
Card table contains a column named "Pin_Number".
The Student_Details table contains fields such as Exam_Number, Name, Age, Sex.
The user has to Enter the Pin_Number which has to be confirmed in the Card table and Exam_Number which has to be confirmed in the Student_Details table and verify that both data's are correct.
Please I need the SQL and PL/SQL queries for this problem.
Thanks

Hi,
I think you need two different queries
You can write a procedure like:
create or replace procedure p1 (p_pin_number number, p_exam_number)
is
r_card_row            card%rowtype;
r_student_details     student_details%rowtype;
cursor c1 is
select *
    from card
   where pin_number = p_pin_number;
cursor c2 is
select *
    from student_details
   where exam_number = p_exam_number;
begin
open c1;
    loop
      fetch c1 into r_card_row;
      exit when c1%notfound;
      .... do whatever you want..... and the samething you can do with other cursor
    end loop;
close c1;
end p1;Hope this helps

Selecting from two tables but making it just one selection

Is there a way to select from two tables and just have one selection appear?
Specifically I have a fact_install_unit, and a fact_install_arch table.
Sometimes the value exists in fact_install_unit.factory_timestamp, and sometimes when fact_install_unit.factory_timestamp is null I need to pull it from the fact_install_arch.factory_timestamp.
sort of like:
(select fact_install_unit.factory_timestamp
from fact_install_unit, fact_install_arch
where fact_install_unit.fl_unit_sak = fact_install_arch.fl_unit_sak
and where fact_install_unit.factory_timestamp is null then display fact_install_arch.factory_timestamp)

nm means "no more" than that
And how are we supposed to know that? You seem to have changed the thread subject to "unfortunately I only have read-only and insufficient priveleges", which is not even a question.
nm means "New Mexico":

Selecting from multiple tables, into one internal table

Hi,
What is the best & most efficient method of selecting from multiple table (in my case 6,) into one internal table?
Thanks,
John
Points will be rewarded and all responses will be highly appreciated.

I have simple example :
First one - Join 5 tables
data : f1 type i,
          f2 type i,
          f3 type i.
start-of-selection.
get run time field f1.
write the query 4 or 5 tables join.
get run time field f2.
f3 = f2 - f1 ( Total time).
Second one - joins 3 table and use for all entries
data : f1 type i,
          f2 type i,
          f3 type i.
start-of-selection.
get run time field f1.
write the query 3 tables join and use for all entries
get run time field f2.
f3 = f2 - f1. ( Total time )
Finally you can have time diffrence between the both sql statement.
