Inserting, deleting in nested tables

I am trying to delete and insert to a nested table.
delete from table (select address from employee where
employeeId = 1 );
or
insert into table (select address from employee where
employeeId = 1 )
values ('street', 'city');
I get the error message:
<b>ORA-22906: cannot perform DML on expression or on nested
table view column</b>
Does anybody know what I am doing wrong?
Thank you.

You can select from a nested table like this
Create table like this
CREATE TYPE Address AS OBJECT (
street VARCHAR2(20),
city VARCHAR2(10)
We may create a type that is a (nested) table of
objects of this type by:
CREATE TYPE AddressTable AS
TABLE OF Address;
CREATE TABLE Employees (
empno number(5),
addr AddressTable
NESTED TABLE addr STORE AS
address_tab;
SELECT ad.city
FROM THE(
SELECT addr
FROM Employees
WHERE empno = 123
) ad 'You can also add a where clause after this to select a particular address if there are multiple addresses
Insert
Insert into employees values (345,
addresstable ( Address('Street','City')));
Hope this helps

  • Insert data into nested tables

    Hi,
    Can someone please advice how can I insert data into nested tables using APEX.
    I have a table "employee" and a column addresses of type address_table_type object which has address1, address2, address3 columns. I want to create form in APEX that will collect address1, address2, address3. I wonder how to do this? should the item be based in database item? if yes then how can I point to the column of address_table_type
    Thanks

    Can you post your tabB type, sample data, and your exact insert statement?
    Is it overwriting or not commiting the inserts?
    Have you traced your session to see what is happening?

  • Please help with multiple insert query into nested table!!!!

    I am having a problem with inserting multiple references to objects into a nested table using the following query:
    INSERT INTO TABLE(SELECT Taken_by FROM courses WHERE course_number= 001)
    (SELECT REF(p) FROM persons p
    WHERE p.enroled_in = 'Computing for Business'
    The database says that p.enroled_in is an invalid identifier. I know why this is. This is because the field enroled_in is part of a subtype of person called student_type and the query above is not accounting for this properly. I would like to know the correct syntax to use so I can insert into the nested table wherever a student is enroled into the 'computing for business' course. My full schema is below:
    CREATE TYPE person_type;

  • Inserting Data into nested table

    I am exploring the differences between OBJECT & RECORD.
    As i am still in process of learning, I found that both are structures which basically groups elements of different datatypes or columns of different datatypes, one is used in SQL and other is used in PL/SQL, please correct me if I am wrong in my understanding.

    Sort of - you can definitely use them for more than just "defining an actual table". (I'm fairly certain you could pass a nested table into a procedure, for example - try it, though - I'm not 100% sure on that - it just "makes sense". If you can define a type, you can use it, pass it around, whatever.).
    Ariean wrote:
    And that nested table could be a record in SQL or an Object in PLSQL or just simple datatype(number,varchar etc)?
    Nested tables are just like any other custom data type. You can create a nested table of other data types. You can create a custom data type of nested tables.
    It could get stupidly .. er, stupid O_0
    CREATE TYPE o_myobj1 AS object ( id1   number, cdate1  date );
    CREATE TYPE t_mytype1 AS table of o_myobj1;
    CREATE TYPE o_myobj2 AS object ( id2   number,  dumb  t_mytype1 );
    CREATE TYPE t_dumber AS table of o_myobj2;
    O_0
    Ok, my brain's starting to hurt - I hope you get the idea

  • Oracle Auditing for Insert/delete in a Table

    Dear Oracle Guru's
    I have a Master table for which records are added manually using the Insert command and not by any front end tools.
    I have no Auditing for this table , like when an insert/delete is made in to this table.
    Does oracle provides any other Tables/views like v$session to find out when such events happens.
    Kindly guide me
    With Warm Regards
    ssr

    Probably not.
    If your database is in ARCHIVELOG mode and you have the archived logs from the point in time that the DML happened, you could potentially use LogMiner to read the redo logs and get information about when the DML happened and who was responsible. That tends, however, to be a relatively painful manual process that is frequently complicated by the fact that most shops get rid of archived logs as soon as they are no longer necessary for database recovery which is frequently a matter of days or weeks.

  • How to Insert records in Nested Table

    Hello Friends,
    I have doubt in below Nested table.
    I have inserted the value in emp table
    EMP TABLE
    EMPNO ENAME PROJECTS
    1 A DATASET
    2 B DATASET
    but not in project_type object. Now I want to insert the record in project_type for name and role field. Please resolve my problem.
    SQL> create type project_type as object

    3 name varchar2(50),
    4 role varchar2(20)
    5 )

    7 /
    Table created.
    Thanks...

    Ok if you have inserted a row in the emp table and now you want to update the projects column which is null then you would do something like:
    update emp
    set projects = projecttable(project_type('..', '..'))
    where empno = ...However say that the projects column is not null and you want to add a new record into the nested table then you would do:
    insert into (select projects from emp where empno = ...)
    values ('...', '...')And finally imagine you have a record in the nested table that you want to update then you would do the following:
    update (select projects from emp where empno = ...)
    set role = '...'
    where name = '...'

  • Insert data from source table to destination table dependning up on a criteria.once inserted delete from source table.

    HI,
    I have a source table with millions of records .I need to insert some of the data (depending on a condition) to a repository table.
    Once they are inserted they can be deleted from the source table.
    The deletion is taking a lot of time .
    I need to reduce the time to delete the records.
    ex:-  1 million records in 8 seconds.
    Had already used bulk collect and cursors but cannot succeed.
    Please suggest how to increase the performance.

    Thank you for your reply.
    I have tried
    select value(t) from table t;
    but it is still not working. I got almost the same answer as before.
    Anyway thank you very much again.

    >
    Well you are doing almost everything wrong that could be done wrong.
    Here is code that works to insert data into your table (the procedure isn't even needed).
    declare
    p_sl_num NUMBER := 1001;
    p_description VARCHAR2(50) := 'Testing Val1';
    inval1 test_type1 := test_type1();
    inval2 test_type2 := test_type2();
    begin
    inval1.extend();
    inval1(1) := test_object1('testx1', 'testx2', 'testx3');
    inval2.extend();
    inval2(1) := test_object2('testy1', 'testy2', 'testy3');
    INSERT INTO test_object_tpe
    sl_num,
    description,
    main_val1,
    main_val2
    VALUES
    (p_sl_num, p_description, inval1, inval2);
    commit;
    end;
    /See Example 5-15 Referencing a Nested Table Element in Chap 5 Using PL/SQL Collections and Records in the PL/SQL doc
    http://docs.oracle.com/cd/B28359_01/appdev.111/b28370/collections.htm#CJABEBEA
    1. You don't even need the procedure since all it does is a simple INSERT into the table which you can do directly (see my code above)
    inval1(1).val1 := 'testx1';There is no element one (1) of 'inval1' since you haven't created any elements yet. You need to EXTEND the collection to add an element
    inval1.extend();And then there is an empty element but 'inval1' is a container for objects of type 'test_object1' not for scalars like 'val1', 'val2', and 'val3'.
    So you can't do
    inval1(1).val1 := 'testx1';You have to create an instance of 'test_object1'
    inval1(1) := test_object1('testx1', 'testx2', 'testx3');And so on for the other collection
    You don't need the procedure (as my sample code shows) but once you populate the variables properly it will work.

  • Inserting into a doubly nested table through an object view

    Can anyone give me an example of an INSTEAD OF trigger that will mediate an INSERT into a doubly nested table of an Object View? Is there syntax that will allow it?

  • Insert /delete data from SAP Z table to Oracle table and opposite

    Hi,
    Can u help me write this FM from the SAP side?
    So, I have two tables ZTABLE in SAP and Oracle table ORAC.
    Let's put three columns in each of them, for example
    TEL1
    TEL2
    ADRESS
    NAME
    where TEL field is primary from ZTABLE to ORAC...
    (in FM there shoud be abap code for writing data in ZTABLE after we press some pushbutton made in sap screen painter..)
    for example, when we write new record in ZTABLE
    00
    112233
    Street 4
    Name1
    this data shoud be inserted in Oracle table ORAC.
    when we write new record in Oracle table for example
    01
    445566
    New Street
    Name2
    this data shoud be inserted in ZTABLE.
    Field TEL1 can be only of two values 01 or 02, other combination is not valid...
    I must have all data from Oracle table ORAC in ZTABLE and opposite.
    It should be the same scenario for DELETE...
    And this communication should be online between sap and table in oracle database...
    Can u help me from sap side? and give idea how to configure on oracle side??
    Thanks a lot,
    Nihad

    I dont know if we can directly connect to a oracle database ( wait for the answers from others on this )
    but in XI we have the JDBC adaptor to insert and retrieve data.
    so for the outbound from SAP the flow can be something like this (with XI in landscape):
    1) You have a screen to maintain a new entry / delete an entry
    2) On save , this record gets saved or deleted from the Ztable in SAP
    3)) In the same screen you can call a proxy class-method (generated using SPROXY transaction ) to send the record to XI.
    4) XI to format it and insert into the oracle table

  • Using Insert and Delete icons in table control wizard.

    Can anyone tell me how to perform a new row insertion or deletion in a table created using the table control wizard.
    I see there is a form fcode_insert_row and fcode_delete_row, but dont know how to call them and what parameters to pass and all.
    Since iam new to SAP-ABAP, some code samples will be a great help.
    Thanks to all in advance.

    Hi Lavanya ,
    You have to add the icons personally in the table control.. . Put fcode for addition button as INSE and delete as DELE ..coding will be already thr in the wizard no need to anything just add icons in the table control by selecting from f4 help on icons option of screen.

  • How to delete the NULL entries in nest table

    Hi,
    After I used a loop and open/fetch cursor populated the object table
    I found there are random NULL entries in my object table (nest table)
    The data look like this
    NULL NULL           NULL
    NULL NULL           NULL
    123     03-MAY-04     ACTIVE
    NULL NULL           NULL
    NULL NULL           NULL
    234     21-MAY-04     ACTIVE
    NULL NULL           NULL
    345     11-MAY-04     ACTIVE
    NULL NULL           NULL
    How can I get rid of those NULL entries in my nest table? So it can become
    123     03-MAY-04     ACTIVE
    234     21-MAY-04     ACTIVE
    345     11-MAY-04     ACTIVE
    Additional info:
    create type myType as object
    (id NUMBER (10,0),
    eff_date date,
    status VARCHAR2(17)
    create type myNestTab as table of myType;
    I have tried Delete procedure in following two ways.
    Version 1:
    FOR i IN l_my_nest_tab.FIRST..l_my_nest_tab.LAST
    LOOP
    IF l_my_nest_tab(i).id IS NULL THEN
    l_curr_event_tb.DELETE(i);
                   END IF;                         
    END LOOP;
    Version 2:
    FOR i IN l_my_nest_tab.FIRST..l_my_nest_tab.LAST
    LOOP
    IF l_my_nest_tab(i) IS NULL THEN
    l_curr_event_tb.DELETE(i);
                   END IF;                         
    END LOOP;
    Both of them give me the error “no data found.” And only left me the first NOT NULL entry in the table.
    123     03-MAY-04     ACTIVE
    Thanks in avdance.

    Hi Vishnu,
    u can write a report program for this and in that use the event  :
    AT NEW <field-name> ( use primary key)
    your statements
    ENDAT
    for eg.
    loop at itab ( herfe itab must be of type of table for which u want to track new entries)
    at new matnr
    write:/ new record
    endat
    endloop.
    schedule this report in background to run in every 5 or 10 mins as per your requirement and hence changes can be tracked.
    regards
    Vinod
