Those are not tables, they are views. Try looking under Adminstration|Schema|Views with schema as SYS. Keep in mind many of the V$ names, such as V$INSTANCE, are public synonyms for V_$ views. For example V$INSTANCE is a public synonym for V_$INSTANCE.

  • Table and Materialized View in different namespaces?

    I've just faced something completly new for me. It appears that there are two objects with the same name and owner. Table and Materialized View have the same names and when I look into system dictionary I can se sth. like that:
    OWNER OBJECT_NAME OBJECT_ID DATA_OBJECT_ID OBJECT_TYPE NAMESPACE
    USER_A USER_TABLE 159381 159381 TABLE 1
    USER_A USER_TABLE 159382 MATERIALIZED VIEW 19
    (I couldn't find how to write above with const length font).
    Two object in different namespace? I thought that Tables and Materialized Vievs have the same namespace.
    Can you please tell me how can I create objects to achieve above result? I would also be grateful if you tell me where to find that topic in documentation.

    Perfectly normal.

  • How to find schema of a table and a view

    Hi,
    I have an old form which uses one table and one view. I know its database. Now I'm making another form in some other database and want to use the old form but for that I need to know the schema of that table and the view so that I can give the schema name and db link to connect (meaning schema.table_name@dbname). How do I find out the schema for that table and view.
    I did a search by using "select owner from all_objects where object_name = tablen" and it says PUBLIC. There's no schema called Public. I can see Public Synonyms but cannot find that table and view in it. So please help. I'm trying since long to find its schema.
    Thanks.

    Hi ,
    Isn't it peculiar that i have declared a public synonym on table BIOGR as user523269 does.... and the sql statement:
    select owner from all_objects where object_name='BIOGR' works.... whereas of user523269 does not...?????
    SQL> select * from dba_synonyms where table_name='BIOGR';

  • Oracle equals_path condition NOT working with table and materialized view

    The user i am using is xdb with dba role.
    1.When i try to use the statement
    SELECT PATH FROM xdb.path_VIEW
    WHERE
    EQUALS_PATH(res, '/home/OE/PurchaseOrders/2002')=1
    the result is
    /home/OE/PurchaseOrders/2002
    2. When i drop the path_view and recreated it like materialized view with statement
    create MATERIALIZED view path_view as
    select /*+ ORDERED */ t2.path path, t.res res,
    xmltype.createxml(xdb.xdb_link_type(NULL, r2.xmldata.dispname, t.name,
    h.name, h.flags, h.parent_oid, h.child_oid),
    'http://xmlns.oracle.com/xdb/XDBStandard.xsd', 'LINK') link,
    t.resid
    from ( select xdb.all_path(9999) paths, value(p) res, p.sys_nc_oid$ resid,
    p.xmldata.dispname name
    from xdb.xdb$resource p
    where xdb.under_path(value(p), '/', 9999)=1 ) t,
    TABLE( cast (t.paths as xdb.path_array) ) t2,

    where t2.parent_oid = h.parent_oid and t2.childname = h.name and
    t2.parent_oid = r2.sys_nc_oid$
    then the equals_path condition STOP working !!!
    3. The same experiment, but i recreate it like table
    create table path_view as .... using the rest of the statement ...
    Can someone help me to understand why equals_path is NOT working on table and materialized view !

    Thanks Jonah. I was under the impression that I already had it but seems like it has to be a direct priv - thru a role doesn't work.
    I granted the reqd privs and then it worked fine. Thx for your help!

  • How to query a table and result together with autonumber

    Hi all
    How to query a table and the result return autonumber for each row together with the table values.
    I have tried rowid but it provide me with characters.

    What is your exact requirement?
    If you want the number of rows selected, you can use rownum.
    select rownum, a.* from <table> a;

  • Query a table and exit when first record found

    I want to query a table and just want to know if any rows matching my query criteria exist in the table. I just want to find one row, irrespective of order and stop the query right there. How do I do that?

    The most efficient way would be either to use rownum = 1 as part of the condition in your second query, but, as written, both will return multiple rows. Your first will need to have an additional predicate and rownum = 1 in addition to the exists.
    Assuming that the predicate can use an index, then the most efficient approach would be either:
    SELECT 1 FROM table
    WHERE <conditions> and
          rownum = 1or possibly:
    SELECT 1 FROM dual
    WHERE EXISTS (SELECT 1 FROM table
                  WHERE <conditions>)Both will do a range scan on the applicable index, stopping when the find the first matching entry. To my mind, the first is clearer in intent.
    To illustrate the error in your first query, consider:
    SQL> SELECT * FROM t;
            ID DESCR

  • Performance difference between tables and materialized views

    hi ,
    I created a materialized view on a query that involves partition table in it.
    When i used the same query and created a table out of it <create table xyz as select * from (the query)> ,the table got created quickly.
    So does that mean performance wise creating table is faster than creating/refreshing the materialized view ?or is that due to the refresh method i use ?Currently i use a complete refresh

    I created a materialized view on a query that involves partition table in it.
    When i used the same query and created a table out of it <create table xyz as select * from (the query)> ,the table got created quickly.
    So does that mean performance wise creating table is faster than creating/refreshing the materialized view ?or is that due to the refresh method i use ?Currently i use a complete refresh Well, for starters, if you created the materialized view first and then the standard table, the data for the second one has already been fetched recently and so will reduce your I/O due to caching, and will therefore be quicker. There are also other factors such as the materialized view creating other internal bits that are required to allow for refreshes to be done quickly, such as the primary key etc which you haven't created on your second creation.
    What you have shown is that two completely different statements running at different times, appear to operate with different speed. It is not a comparison of whether the materialized view is slower or quicker than the create table statement.

  • Select data from a table and a view: field with same content and different type

    hi all,
    I need data from a table hrp1001 and a view V_USR_NAME. What they have in common are the content of the fields SOBID and BNAME .
    It will be easier if those fields add a same type but they dont.
    Any suggestions for a workaround?
    Thanks

    Hi Ramesh,
    Specify the date format as YYYYMMDD in where condition.
    Dates are internally stored in SAP as YYYYMMDD only.
    Change your date format in WHERE condition as follows.
    data itab like equk occurs 0 with header line.
    select * from equk into table itab where werks = 'C001'
    and bdatu = <b>'99991231'.</b>
    I doubt check your data base table EQUK on this date for the existince of data.
    Otherwise, just change the conidition on BDATU like below to see all entries prior to this date.
    data itab like equk occurs 0 with header line.
    select * from equk into table itab where werks = 'C001'
    and <b> bdatu <= '99991231'.</b>

  • How to rename tables and refresh views

    Hi all
    I need to write a script that will rename several tables and at the same time I would like to refresh all the views that point to this table.
    questions:
    - how do I rename a table
    - how do I refresh the views that point to this table?
    Thanks
    J

    Hello,
    You might have to write pl/sql to recreate all views depends upon the tables you just renamed. You can use user_dependencies to identify the views and create sql to use new_table_name
    DECLARE
       CURSOR mcur
       IS
          SELECT table_name
          FROM user_tables
          WHERE table_name IN ('A1');
       v_sql   VARCHAR2 (100);
    BEGIN
       FOR cur IN mcur
       LOOP
          v_sql   :=
             'RENAME ' || cur.table_name || ' to ' || cur.table_name || '_NEW';
          DBMS_OUTPUT.put_line (v_sql);
          EXECUTE IMMEDIATE v_sql;

    And u have attached a Different VO on the page... Right...
    Now what u can do is....once u click on apply....
    u can set the each attributes of EO based VO explicitly via code, from the values of second VO.... and then commit.....
    Perhaps this might help...

    otherwise take the OBJECT_TYPE from user_objects -
    some sort of DECODE?
