How to return data using the object type?

Hello all - I have an obligation to return the values object type.

In the same way as

list - Plan1, Subplan1, Fund1, 2 Fund Fund 3

list - Plan2, Subplan2, Fund2

list - plane3, Subplan3, not funds


To achieve this I wrote below proc but its giving as response below which is does not correspond with my requirement. Someone has an idea how to write code to get the list of funds against each plan in each line?



Output:

PDB01. () T_T_CONTRACT

PDB01. T_O_CONTRACT ('p1', 's1', PDB01. T_O_FUND ('p1', 's1', 'f1')),

You can declare the attribute OV_FUND as T_T_FUND data type:

create or replace type t_o_contract as object (

    Hi André,.

    You can create new types of collection (varray/table) in two ways:
    (1) in the browser - find 'Types of data' > 'Types of Collection' node menu dropdown - there just 'create new collection type' it
    (2) in the types of data model diagram - you can create collection "some type structured" or collection of references to the it - use 'new Collection... '. "tool and click first on sight structured type and after the structured type that will contain the collection - new attribute is added to the latter and if there is none this type of collection already didn't set the new collection type are created and you can change it later.

    Hi gurus

    I created an object type and able to fill the values in it, now I want to create a nested table type of this object and fill it but looks like I'm doing something wrong, see my code below.

    Hi user,

    Here is another method that you can try-

    CREATE OR REPLACE

    ABC of the PROCEDURE

    IS

    v_print countries_t: = countries_t (countries_o('01','A',11));

    BEGIN

    DBMS_OUTPUT. Put_line (v_print (1).) COUNTRY_ID | v_print (1). COUNTRY_NAME | v_print (1). REGION_ID); -you're accessinf the first element of the nested table, which in turn points to the object.

    END;

    In the sections of the declaration you have assigned values to the nested table.

    Not valid. This makes no sense and breaks all the rules of scope-resolution. And if it is in a single database, or uses tables in databases, is not relevant.

    Each object must be particularly well identified. If you cannot do this:

    select * from (table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3) a

    3 objects cannot share the same alias. Example:

    SQL> select * from (dual, dual) d;
select * from (dual, dual) d
                   *
ERROR at line 1:
ORA-00907: missing right parenthesis

    You need to combine objects - by using a join union or similar. He will have to be done as follows:

    SQL> select * from (select * from dual d1, dual d2) d;
select * from (select * from dual d1, dual d2) d
       *
ERROR at line 1:
ORA-00918: column ambiguously defined

    However, we need to have unique column in a projection of SQL names - so the join of the need to project a unique set of columns. So:

    SQL> select * from (select d1.dummy as dummy1, d2.dummy as dummy2 from dual d1, dual d2) d;

DUM DUM
--- ---
X   X

SQL>

    I suggest that you look carefully at what opportunities are and how it applies in SQL - and ignore if the referenced objects are local or remote, because it has no effect on the basic principles of scope-resolution.

  • How to save data in the text file of Spartan 3

    Hi all

    I would like to kindly save the data table text file or a spreadsheet on vi using fpga spartan 3e as an fpga target. Once I added all the functions related to the operation of file, it gave an error that these functions are not supported by the target device.

    could you please help me with this

    Thank you

    Rania

    Hi David,

    Thank you for posting. You use LabVIEW? If so, what version of LabVIEW FPGA do you use? You use a host VI, or any deployment of code at your target to run? The file IO VI probably won't compile to target because they are not intended to be used on your host computer. Resources and the paths of files do not exist on the target FPGA, but rather on the side of the host. I have included a link below that describes how to transfer data between the FPGA and host. I hope this helps!

    • The ORACLE_LOADER access driver is the default value. It loads data from external to internal tables tables. The data must come from text data files. (The ORACLE_LOADER access driver cannot perform the unloading; in other words, he can't move data from an internal table to an external table.)
    • The ORACLE_DATAPUMP access driver can perform loading and unloading. The data must come from binary dump files. Loads of internal tables of external tables are made by extraction from files of binary dump. Unloading of internal tables to external tables are make by filling binary dump of the external table files. The ORACLE_DATAPUMP access driver can write files to dump only as part of creating an external table with the SQL CREATE TABLE AS SELECT statement. Once the dump file is created, it can be read many times, but it cannot be changed (i.e., no DML operation can be performed).

    You will be able to unload and create an external table (using the ORACLE_DATAPUMP type), but the file will not be csv or readable in the same direction.
