Recreating a table with child table dependencies

Hi.
I have two tables P (Parent) and C (child), with foreign key dependencies. How can I recreate the P table without losing the child dependencies?
Thanks in Advance.

Well I got this as an interview question. So what I guess what it means is to recreate the table for administrative purposes (maintenance/defragmentation etc) and later recreate the dependencies in to the C table.If this is a good interviewer, they will be expecting you to ask some questions to find out the restrictions on what you're allowed to do.
Obviously you could extract any dependency information from the data dictionary, so it won't be "lost". Then you could switch the database into restricted mode and/or shut down the listener. Drop any RI constraints, recreate table, recreate constraints, restart listener, take database out of restricted mode. However, this might be a catastrophic strategy from the perspective of the business - so if you try to answer the question without first asking questions (or at least starting with "there are various methods, depending on the restrictions you need to impose from a business perspective, for example ...)

Hello Gurus..... ISSUE with child Table update

I have an issue with child table update
I have created a GTC with one parent table and two child tables. I'm able to update the parent table and the values are found in db, but the ISSUE is the child Table values are not updating the db.
please give me a solution
regards
Srikanth

If you are keeping referential integrity in the database, not in the application, it is easy to find the child and parent tables. Here is a quick and dirty query. You can join this to dba_cons_columns to find out on which columns the referential constraints are defined. This lists all child-parent table including SYS and SYSTEM users. You can run this for specific users of course.
select cons1.owner child_owner,cons1.table_name child_table,
cons2.owner parent_owner,cons2.table_name parent_table
from dba_constraints cons1,dba_constraints cons2
where cons1.constraint_type='R'
and cons1.r_constraint_name=cons2.constraint_name;

/I would like to make exchange partition using stage table, and everything is going fine on all tables, but only on a few of them (listed source is one of them, and they're only tables with nested tables wihin), where I get an error.. but sometimes ;)
on a statement like:
ALTER TABLE IS_PODACI245_ARH EXCHANGE PARTITION P_201106 WITH TABLE IS_PODACI245_STAGE EXCLUDING INDEXES WITHOUT VALIDATION;I got an error:
ORA-00001: unique constraint (TXV.SYS_C0032911) violated
it's an unique index between parent and nested table.
what could cause that problem?

Dear,
I suppose that the unique constraint
ORA-00001: unique constraint (TXV.SYS_C0032911) violatedis the one you 've created on the nested table IS_PODACI245_STORE_TABLE
If so, why not disable that constraint and try again.
I have never exchanged such a kind of partitioned table having a nested table in it. But, I could imagine that the cloned non partitioned table IS_PODACI245_STAGE should at least be the exact image of the partitioned table IS_PODACI245_ARH (of course without the partition part) but with the nested table part and including all indexes
In addition, if you have a parent/child relationship between your partitioned tables, then there is a chronological order of exchange starting by the child and then finishing by the parent
see the following link for more information about this order of exchange (and comment 2 for an example also)

Import tables with nested table : ORA-00600

In Oracle 9.2
Create object, type as table, and table with nested table (store as syms_ntab) are successfully.
Also its export.
In process of import on another server (also 9.2, 'fromuser=one touser=two') shows errors:

Linking user table with system table

Hello, I'm trying to link a user table with IC table in order to asign many sales person to a customer.
I've created a new button in the IC form. When clicked a new form is opened to asign sales person to the IC. Now I need to retrieve the records assigned to this IC. How can I do that???
Regards.
Angel.

Hi Angel,
I would put a matrix in the new form where you could see/asign/delete the sales person.
Have a look at this post where you can find a great code from Sebastian Danober to fill a matrix from a recordset.
Another option could be to modify the existing IC form and add a new folder with a matrix where you can manage the sales person.
Check this other post with code for adding folder to an existing form.

Mix object tables with relational tables?

Hallo,
is it possible to mix object tables with relational tables in one database?
I didn't succeed in assigning a foreign key from a relational table to an object table.
Is this only working with column objects in relational tables?

Hi
is it possible to mix object tables with relational tables in one database?
Every database contains both types of tables. So, it is basically not a problem.
I didn't succeed in assigning a foreign key from a relational table to an object table.
Is this only working with column objects in relational tables?It would be interesting to know how you tried... e.g. what error you get... Here an example (executed on 11.1).

When you create a table type without an object, i.e. a single column type like this you will get the column name as COLUMN_VALUE.

WD4A Dynamic ALV Table with dynamic tables

Hi all,
first I want give you the information what I try to do.
I have an another WD4A application for administrative use in which I can assign certain tablefields to a certain user. You can say it's something like a customizing application.
In the next application (with my issues) I will display the tables for the user, but these tables are not the complete table.
I have a node in my context of the component controller which is bound to my ALV. I add during the runtime attributes to my node.
* .... coding ....declaration
* get the node
lr_node = wd_context->get_child_node( 'M_TABLE' ).
lr_node_info ?= lr_node->get_node_info( ).
* remove the attributes, if exists
lr_node_info->remove_dynamic_attributes( ).
* .... coding ....
*   add attributes
    LOOP AT l_t_m_table INTO l_s_m_table.
      CLEAR ls_attribute.
*     name of the attribute
      MOVE l_s_m_table-NAME TO ls_attribute-NAME.
*     DDIC type of the attribute
      MOVE l_s_m_table-TYPE_NAME TO ls_attribute-TYPE_NAME.
*     If the DDIC has a gen namespace like /B135/ replace the / with _
      REPLACE ALL OCCURRENCES OF '/' IN ls_attribute-NAME WITH '_'.
*     add the attribute
      lr_node_info->add_attribute( EXPORTING
                                     attribute_info = ls_attribute ).
    ENDLOOP.
This coding works fine I get the columns in my ALV. Then I tried to fill my ALV table with data from a database table.
I created dynamicly an internal table with the following coding:
*   Create dynamic table
    CALL METHOD CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE
      EXPORTING
        IT_FIELDCATALOG = l_t_FLDCAT
      IMPORTING
        EP_TABLE = l_t_NEW_M_TABLE.
*   assign the table
    ASSIGN l_t_NEW_M_TABLE->* TO <M_TABLE>.
*   structure of table
    CREATE DATA l_s_NEW_M_TABLE LIKE LINE OF <M_TABLE>.
    ASSIGN l_s_NEW_M_TABLE->* TO <l_s_m_table>.
* get data from database
SELECT * FROM (l_m_table) INTO CORRESPONDING FIELDS OF TABLE <M_table> WHERE OBJVERS = 'A'.
With this coding I get the data from the database and only the required fields that means I have e.g. an itab with columns1, columns3, columns4 from the database.
I also added e.g. these columns (columns1, columns3, columns4 from the database) to the node as attribute. Now it should be possible to bind the table to the structure with this coding:
lr_comp_usage_m = wd_this->wd_cpuse_usage_alv_M_table( ).
*   create component if not active
    IF lr_comp_usage_m->has_active_component( ) IS INITIAL.
      lr_comp_usage_m->create_component( ).
    else.
* set data if node exists
      l_ref_interfacecontroller = wd_this->wd_cpifc_usage_alv_M_table( ).
      l_ref_interfacecontroller->set_data( lr_node ).
    endif.
*   bind table
    lr_node->bind_table( <M_TABLE> ).
Now, I get an error, which is caused by the table binding.
In ST22 I get:
Short text
    Line types of an internal table and a work area not compatible.
What happened?
    Error in the ABAP Application Program
    The current ABAP program "CL_WDR_CONTEXT_NODE_VAL=======CP" had to be
     terminated because it has
    come across a statement that unfortunately cannot be executed.
Error analysis
    The statement
       "INSERT wa INTO TABLE itab"
    requires the lines of the internal table "TABLE" and the
    work area " wa" to be compatible. Compatibility means
    equivalence in the context of ABAP/4 type checking.
    In this case, the condition is not satisfied because the internal table
    "TABLE" has the line type "u" and the length 28, but the work area " wa"
    has the type "C" and the length 2.
    (If the work area " wa" is the header line of the internal
    table "TABLE", the above inconsistency can arise if an internal
    table t with the line type T1 is passed to a subroutine (FORM or
    FUNCTION) as an actual parameter and the corresponding formal
    parameter p is declared in the subroutine by "TABLES p STRUCTURE T2".
    If then T1 and T2 are incompatible, the header line p
    has the type T2 (specifed by STRUCTURE), but the internal
    table p has the line type T1 (passed from the actual parameter)).

   23   endif.
   24
   25 endmethod.
Any suggestions? Is it allowed to use bind_table() with a field symbol?
Another strange thing is that if I try the same with static itab and attributes during runtime it works, but only if the fields of the itab has the same name as the attributes, which means that I can not use itabs with fieldnames like /BI0/S_CUSTOMER and if I can not use them it's difficult to read data from database with SELECT * FROM ... INTO CORRESPONDING FIELDS OF TABLE itab.
Thanks in advance for your suggestions!
Best Regards,
Marcel

Hi Francois,
I solve it with the RTTI and the method
lr_node_info = lr_node_info->add_new_child_node(
                      name = 'Dynamic_TABLE'
                      IS_MANDATORY = ABAP_false
                      IS_MULTIPLE = ABAP_true
                      STATIC_ELEMENT_RTTI = lr_struct_descr
                      IS_STATIC = ABAP_false
I don't know why it doesn't work with adding attributes and binding the table after adding the attributes.
Anyway thanks for your help.
Best Regards,
Marcel

How to check that my table is parent table or child table before trucating

Hi:
say i wanted to trucate a table .the table might be a parent table or might be a child table.if its a child table then there wouldnt be any problems in truncating.
if its a parent table the i believe i would have to diable all the foreign key constraints from the child table referring to the parent table ..my question is
1. i have a table say ABC. before truncating how do i find out if table ABC is a parent table or not?
2.lets assume i tried to truncate the table ABC and i got the error saying that disable the foreign keys on the child table referring to the parent table ABC.
in my schema there are say 50 tables.out of which there might be 10 odd child tables referring to my parent table ABC.
so my question here would be how do i specifically find out these 10child tables referring to the Parent table ABC so that i can disable the foreign keys on the child tables.
Thanks 4 ur time in reading this and hopefully i think u wld give me a solution!!

Hi,
Try this SQL below:

and o.constraint_type in ('P','U') and r.constraint_type = 'R'
and o.table_name = 'ABC';Cheers

your lov problem can be because of your form modules database interaction property. i have the same problem.in form module properties "INTERACTION MODE" must be blocking.

my Prob. Is that when I invoke the LOV first time it takes too much time

Join EQUI table with other table so as get address detail.

Hi All,
Can any one help me in the following case :
I have to pass Equipment No. EQUNR on the selection screen and get Address detail (city, region, state, country, zipcode )
now I am getting all this address related field in KNA1 table. Also I am able to join this two table with
KNA1-KUNNR join EQUI-KUNDE as common field.
Turning point
when I am passing test data of Equipment No. EQUNR 60099204 I am not getting the address detail,
because after passing EQUNR I am not getting KUNNR.
So can any one please help me in joining EQUI table to some other table with field name so that I can get the address detail.
Thanks

Hi,
The join between the table EQUI-kunde join KNA1-kunnr is ok but it not working for every value.
Example :-
In EQUI table when we pass Equnr - 60099204 we need to get some value in KUNDE field, then only it will join to KNA1 table. But this is not happening, I am not getting value for KUNDE, hence join is not performing.
So I need some other solution so that when we pass EQunr we can get the address details
one thing more equnr 60099204 is having address detail, if we'll check IE03 (transaction by clicking address envelop)
Thx.
