Recursive query for finding parents and children against two tables

Hi I have two tables where the data is stored hierarchially.
I have found using connect_by, level and other oracle functions doing its job when the data is in one table.
Can I traverse against two tables by using the same oracle functions.
My Table A can go 2 levels deep in my hierarchy and level 3 and so forth has to be done against a different table.
Appreciate your insight..
Thanks in advance

The number of levels that I can traverse in the first table is dynamic (sometimes 2 levels and sometimes 3 levels and actually no level limit) and then has to dynamically start looking at second table for finding any more levels in the other table.
I was able to implement them seperately and union them.
I was more looking for a comprehensive solution to reduce the number of lines that I have to maintain...
Thanks in advance

  • Query to find parent & al children customer based on child Party_number

    Hi All,
    I am working analyzing some TCA hierarchy data for a new customer dimension table design for a project and also for better understanding of the TCA.
    I need a query which can help me in listing all the PARTY IDs of all the customers that come under the top most rolled up customer which is found based on an any random input CHILD PARTY NUMBER.
    In simple terms.
    1. I have any random PARTY NUMBER of any customer in HZ PARTY.
    2. Using that PARTY NUMBER I need to find it's top most level rolled up parent customer.(i.e. Which global parent customer it falls under)
    3. Now based on the global customer found in the second step, I need to find all the customers (and all its global subsidiaries) under that one global name.(All the customers which are spread across the glob)
    I am currently using the following tables to build the logic.
    hz_parties
    hz_relationships
    hz_hierarchy_nodes
    fnd_lookup_values
    Anybody who has done such an exercise or has any kind of inputs, queries which can help, etc.. it would be really helpful.
    Thanks a lot.
    Thank you,
    Warm Regards
    Goldi

    hi goldie,
    u can use
    party_id (pk) from hz_parties,
    party_id(fk) and cust_account_id(pk) from hz_cust_accounts,
    cust_account_id(fk) from AR.HZ_CUST_ACCT_RELATE_ALL.
    i hope u can get the way for your answer..
    pls let me know, it worked or not.
    Regards.

  • SQL Query to find out similar names in two tables

    Hi,
    I want to write a query which will return the records by matching the two table with the similar name.
    that is I have two tables table1 and table2, and in table1 the column1 is having data like
    ABC INC
    The international Company
    and in the table2 has the column1 which has the data like
    ABC Corp
    The Financials Corporation
    So as per the requirement now my select query should return 1 row as ABC INC and ABC Corp are similer.
    and both the tables have around 50,000 reords so I cannot just take the first word by using substring and tryto match both, this will work only for names like ABC INC and ABC Corp but it will not return the names like
    "Instruments International Company" and "International Instruments Company"
    Please can any one help me?

    Hi,
    It sounds like you want a Top-N Query , something like this:
    WITH    got_nums   AS
         SELECT     table_x.*     -- or list columns wanted
         ,     ROW_NUMBER () OVER (ORDER BY  call_date      ) AS a_num

    ;This forum is devoted to the SQL*Plus and iSQL*Plus front ends. This question doesn't have anything to do with any front end, does it? In the future, you'll get better response if you post questions like this in the PL/SQL.
    I hope this answers your question.
    If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and also post the results you want from that data.
    Explain, using specific examples, how you get those results from that data.
    Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

  • Write a query for finding STDDEV for OLAP Cube

    Can anybody post a sample query which will find the standard deviation of sales for each month in the sample GLOBAL OLAP schema for Oracle 11g.
    The OLAP option automatically generates a set of relational views on cubes, dimensions, and hierarchies in Oracle 11g. So how can i write a query for finding the Standard deviation on these views.

    The easiest way to do this is to do this directly within the AW using a custom calculated measure. In AWM11g you can use the 11g custom measure wrapper to execute the STDDEV function:
    olap_dml_expression('function',data type)
    For example
    olap_dml_expression('STDDEV(cube_name, time_dimension_name)',number)
    You can then simply expose this calculated measure as another column in your SQL View and then there is no need to use the SQL equivalent. This means the calculation is performed inside the AW (which is as close to the source data as you can get) ensuring performance of the whole query remains high.
    If necessary you can take this a step further, if required, and wrap the STDDEV calculation within an OLAP DML program that would allow you to manipulate the status of time within the calculation. For example, you may want the STDDEV calc to only take into account the last 12 time periods rather than all time periods currently in status.
    Hope this helps

  • How to create Parent and Children is a tree table / trigger sequence number

    How to create Parent and Children is a tree table when the primary key of the parent is generated via a trigger and a sequence number in the database?
    My problem is when I create a parent and then right away a children. The parent still not have a primary key until the transaction get to the database. I get a error when trying the create the children, cannot insert null in the foreign key field of the children.
    Please help.
    Stephane

    You should have the parent key be marked as a DBSequence type.
    Then you should have the association between the master and detail defined as composite association to make sure that the posting order to the database is correct.

    How to create a graph representing a big tree(parents and children are known)?
    Thank you so much!
    Also, I need to write the graph into a jpg/gif file or display the graph in the web browser.
    I got a code from JGraph and can create the graph I want, although unextendable. However, JGraph define the graph as class Gscene instead of Img or BufferedImg or RenderedImg. Therefore, I couldn't use ImageIO.write(image, ext, file) to write the graph into a jpg file.

    Hi Jamesdwills,
    Welcome to the Support Communities!
    If you are using the same Apple ID on both devices, the Game Center profile should be the same.
    Check out this information from the iPad User Guide.  Try signing out of the Game Center on both devices and then sign back in with the correct Apple ID:

  • How to find the structural difference between two tables

    you could try something similar to this, for each table pair that you want to compare:
    SELECT 'TABLE_A has these columns that are not in TABLE_B', DIFF.*
      FROM (
            SELECT  COLUMN_NAME, DATA_TYPE, DATA_LENGTH
              FROM all_tab_columns
             WHERE table_name = 'TABLE_A'
             MINUS
            SELECT COLUMN_NAME, DATA_TYPE, DATA_LENGTH
              FROM all_tab_columns
             WHERE table_name = 'TABLE_B'
          ) DIFF
    UNION
    SELECT 'TABLE_B has these columns that are not in TABLE_A', DIFF.*
      FROM (
            SELECT COLUMN_NAME, DATA_TYPE, DATA_LENGTH
              FROM all_tab_columns
             WHERE table_name = 'TABLE_B'
             MINUS
            SELECT COLUMN_NAME, DATA_TYPE, DATA_LENGTH
              FROM all_tab_columns
             WHERE table_name = 'TABLE_A'
          ) DIFF;that's assuming, column_name, data_type and data_length are all you want to compare on.

  • Sql query to find answered and received calls for month or day

    Hi  experts !
    1.Any one help in finding out the received, answered and missed ,transfered  in  /  out  calls  in  UCCE  using SQL query for a particular month or day.
    2. We have some  custom report templetes defined ,  need to  know  , how can we  write Sql  query  to  get those  values  from  custum reports.
    due to some issues,  cannot use  webview .

    Hi,
    there's no such thing as reporting "for a particular Team". Teams in ICM are for administration purposes only (to have grouping of agents). ICM does not count the number of calls received by "teams". If there is a report in Webview "by team", it's always by agent. Try to run the report against a team once and then try to remove certain agents from that team - you'll see the difference.
    What you are looking for is either reporting by Agent or by Agent/Skill group combination.
    Try to explore the
    - Agent_Half_Hour
    - Agent_Skill_Group_Half_Hour
    - Skill_Group_Half_Hour
    database views.
    The database schema documents are here:
