I have a table which contains the connectivity details. It is telecom data. The table contains the relation between the point features(Ex: Terminal) and linear features(Ex: Cable)

I have a main table : CLAIMS_MAIN, in which claim_id is a primary key I have another table : CLAIMS_TRANS , in which claim_id is not a unique key, I mean, there can be more than one records with the same claim_id.. but the column transaction_id is unique, but transaction_id column doesnt exist in the main claims table.
It is required to join both these tables on claim_id...
I am trying to establish PK-FK relationship between 2 tables. Table 1 has VACC_ID as a primary key. Table 2 has VACC_ID and SCH_ID as the primary keys. I am trying to add VACC_ID from Table 2 as a FK to Table 1. This is the code I used
I also tried to add it without writing the query and editing the Table 1. By default, I am getting 2 columns(both VACC_ID) in the local column being referenced to the 2 primary keys(VACC_ID and SCH_ID) of table 2. I also uploaded the screeshot of the error, when I run the query.
I am working on form builder 6i. I have a header block A(Multi record block), child block B. Both are non control blocks. My requirement is, if i put the cursor in any header record, i want to auto populate corresponding child record like in master child relation.
which trigger i need to write logic to auto populate the child record.
On a form I have 2 blocks, shown on different tabs. Relation created by forms wizard. The relation works great when navigating through the blocks, the details for the master are shown fine.
Example for this form is master block is a type of food. Detail block is list of ingredients.When creating a new type of food, if it's = CAKE we insert records based on a select on another table into the ingredients table.Else, the user has to manually create the ingredients.
Upon commit of the form on master block (must be saved to enable detail block tab), the ingredients are not displayed but are there. If I execute query by hitting F8, the records are present.
Why is the populate-details trigger not being fired or what am I missing?
We are using Oracle 10g and have 10 tablespaces defined for our Database which have 108 tables. Size of 108 tables is around 251 MB as seen during importing the dump. While creating these 10 tablespaces I used below parameters for allocation of space
SIZE 1M REUSE AUTOEXTEND ON NEXT 1M MAXSIZE 1M;
which set the initial space for 10 tablespaces to around 1032Kb each. Now my Question is after importing the dump , how the disk space for 10 tablespaces increases to 398 MB in total ?
Is there any relation of Tablespace disk space and Actual Data present in the tables ?

Note:- I got only this that this query is alternative of self join and it is giving manager name along with mgr id for each employee but when it gives output i couldn't able to understand how to identify who is manager of whom. Tell and explain with clause in oracle , i only know it is alternative of inline view but i want to know how does it work and how to use 'WITH' in oracle query if possible.
I want to display result with respective levels. for example p21 ,p30 are coming under first level . p22,p25 ,P31,P32are 2nd level. p23,p24,p26,p27 are 3rd level p28,p29 are FOURTH level item_id's.
Already I 'VE tried using CONNECT BY PRIOR clause.BUT STILL I COULDN'T GET THE RESULT.
create table test_circular_data(c1 varchar2(10),c2 varchar2(10)); insert into test_circular_data values ('c1','l2'); insert into test_circular_data values ('c1','l3'); insert into test_circular_data values ('c3','l3'); insert into test_circular_data values ('c4','l3');
commit;
There is a circular relation between columns c1 and c2, so what I'm trying to retrieve is something like that :
c1--> l2 --> l3 --> c3 --> c4
The steps to get that result is :
1.- c1 related to l2 : c1-->l2 2.- c1 related to l3 : c1-->l2-->l3 3.- l3 in the list and related to c3 : c1-->l2-->l3-->c3 4.- l3 in the list and related to c4 : c1-->l2-->l3-->c3-->c4
I have a hierarchical data structure where a child can have many parents, and a parent can have many childs.See the attached file hierarchy_iliustration.jpg. This example has 4 hierarchy levels, in real problem there can be unlimited number of levels.I want to write a SQL query that lists all indirectly dependent child nodes for a given parent node.
Test structure for example attached:
CREATE TABLE TEST.NODE_T ( ID NUMBER PRIMARY KEY, TEXTAS VARCHAR2(254) );
I have a table (Parent - Child).There is a requirement to maintain this table, thats the hierarchy of the oraganisation.So, every quater they will be updating the table. They will be importing the data through an excel and in that excel there are 3 action items,
For Update:What all validation can come for an updation of an hierarchical data in general.Like = how to derive the level value at database side when the id is updated to some other level.= How to maintain the relation. A -> B -> D ( A is the grand parent here).A -> Ceg: if B is updated as parent node of A, then we should throw error (cyclic data). Any more validations for hierarchical data
How to count siblings in a hierarchical query? I'm trying to get a listing of employees
SELECT LEVEL, last_name||', '||first_name AS Manager, count(employee_id) FROM employees START WITH manager_id IS NULL CONNECT BY PRIOR employee_id = manager_id GROUP BY level
This returns 4 levels. I'm wanting to add up the number of siblings under the level 2 instead of listing them all.
I want to insert 1st two rows into Hierarchy table, then I would like to update Supervisor_2 to Supervisor_4. Here I don't want to use 'CONNECT BY PRIOR', as it take more time to execute (there are millions of records).SQL code for same.
So each Level(L1 ..L4) has zero or many child levels which further has more levels.With out using PL/SQL how can we write a Select query to give me a distinct of all children, all the way to the lowest level (L4).Example: give me all the children where L1 = 3.Result: 31, 32, 33, 311, 322, 333, 3111, 3222, 3333Is it possible to write such a query or am I asking too much logic out of a select and should go with PL/SQL.
That�s generally the format the values would appear in the table if I just did a standard select. I want it displayed in a more hierarchical Parent � child way.
The format I need to get out is as follows: Lvl KeyParKey hasCh 1k101 2k34k10 2k22k11 3k56k220 3k109k221 4k61 k1090 3k67k220 2k24k10 1k200 1k301 2k13k30 2k52k30 2k35k30 2k13k30 1k401 2k11k40
I am using oracle forms 9i. I have to create a Hierarchical Tree and attach checkbox at its node,so that user can select which tree he want in its further processing.
I'm trying to determine if/when a possible Hierarchical circular reference will occur in my data
Sample Hierarchical structure that I have
Emp -> Supv A BA CB DC EC
[Code]....
Finally, to my question. It seems that I can detect the problem After it happens but do I need a trigger on the update statement to detect if/when a possible circular reference will occur?? or can I run a sql statement prior to update to detect possible circular reference?
I have a hierarchical tree with two parent nodes. Each parent node has different number of child nodes. Can i disable or hide a node according to some condition?
