RECORDS AND TABLES

CAn any explain why records and tables are used in PL/SQL?

One thing I forgot to mention: If you're an 8i client, then in
8.1.6 you'll be able to use JPublisher to solve this problem,
since it'll generate these wrappers for you.

Definitions of record and table type

Im confused with the definition of record and table type. Below is my understanding, Please correct me if anything wrong. Thanks in advance!
Record type can only hold one record with multiple fields.
Table type is an array (multiple records) with only one field
Table type defined with %rowtype (table of records) is an array of multiple records with multiple fields.

I am not sure that I understand what you are asking. I have not heard the term table type before.
However, I think a record type is more closely aligned to the %rowtype declaration. Maybe a collection is what you are looking for with the term table type.
From the Oracle 10g documentation:
%ROWTYPE
In PL/SQL, records are used to group data. A record consists of a number of related fields in which data values can be stored. The %ROWTYPE attribute provides a record type that represents a row in a table. The record can store an entire row of data selected from the table or fetched from a cursor or cursor variable.
Columns in a row and corresponding fields in a record have the same names and datatypes. In the example below, you declare a record named dept_rec. Its fields have the same names and datatypes as the columns in the dept table.
DECLARE
dept_rec dept%ROWTYPE; -- declare record variable

Defining Record and Table Types

Is there a good tutorial out there somewhere that provides good examples on how to define and work with Record and Table Types? How to define and work with an entire record or table as opposed to just a variable?
For instance- I'd like to create a cursor of records from a table, loop through each record to examine variable values, and in some instances insert those entire records into another table.
Thanks in advance for any suggestions.

Oracle documentation is excellent (Lots of live examples that can be cutNpaste) place to start.
http://download.oracle.com/docs/cd/B10501_01/appdev.920/a96624/05_colls.htm
Is there any thing specific you are looking for?

Calling Oracle Stored proc with record type and table Type

I have a oracle SP which takes record type and table Type which are used for order management.
Is there anay way to populate parameters with these datatypes and call the stored procedure using ODP.NET?
Please help.
Thanks in advance

Hi,
ODP supports associative arrays and REF Cursors. There is no support for PLSQL table of records.

How does a record type and table type works

Hi,
How a record type and table type work for the ref cursor,
below i m giving an example but its giving me errors
can any one help me for this?
declare
type empcurtyp is ref cursor;
type rectype is record (veid t.emp_id%type, vename t.ename%type);
TYPE tabtype IS TABLE OF rectype;
empcv empcurtyp;
vtab tabtype;
begin
open empcv for select emp_id,ename from t;
loop
fetch empcv into vtab;
exit when empcv%notfound;
dbms_output.put_line(vtab.vename||vtab.veid);
end loop;
close empcv;
end;
here we hav table t and i m taking only two fields of the table t which r emp_id and ename.

Hi,
What errors are you getting with this? From experience you don't need a loop to put the records into the ref cursor its usually done on block.

I HAVE A SOURCE TABLE WITH 10 RECORDS AND TARGET TABLE 15 RECORDS. MY QUESTION IS USING WITH THE TABLE COMPARISON TRANSFORM .I WANT TO DELETE UNMATCHED RECORDS FROM THE TARGET TABLE ?? HOW IT IS ??

Hi Kishore,
First identify deleted records by selecting "Detect deleted rows from comparison table" feature in Table Comparison
Then Use Map Operation with Input row type as "delete" and output row type as "delete" to delete records from target table.

How feed many record in table component and not use append command again

hi master
How I feed Multiple records in table component and not use append and save command again and again
Same as oracle grid
I give many record and save one time
Please give me idea how I add Multiple record and save one time not use append and save command again and again
Thank�s
aamir

Hi!
appendRow() method just add temporal row. For add them to DB commitChanges() method should be used. So you can use appendRow() method several times, fill every new row and only then use commitChanges() method. In this case all new rows will be added to DB per one time.
Thanks,
Roman.

Comparing Two tables with 300k records and update one table

Could you let me know how to compare two tables having 300k records and update one table.below is the scenario.
Table Tabl_1 has columns A,B and Tabl_2 has columns B,new_column.
Column B has same data in both the tables.
I need to update Tabl_2 in new_column with Tabl_1 A column data by comparing B column in both tables.
I m trying to do using PLSQL Tables.
Any suggestion?
Thanks.

Hi,
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved, so that the people who want to help you can re-create the problem and test their ideas.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
If you're asking about a DML statement, such as UPDATE, the CREATE TABLE and INSERT statements should re-create the tables as they are before the DML, and the results will be the contents of the changed table(s) when everything is finished.
Always say which version of Oracle you're using (for example, 11.2.0.2.0).

Why are you trying to use PL/SQL tables? If tabl_1 and tabl_2 are regular database tables, it will be much simpler and faster just to use them.
Depending on your requirements, you can do an UPDATE or MERGE, either in SQL or in PL/SQL.

Get value from table record and set Disabled property...

Hi! I have table in my JSPX page. I search for records and then press on one of the records with right click, see: http://my.jetscreenshot.com/2677/20120203-fas1-30kb

I need some working examples with pl/sql records and pl/sql tables.

i am new to pl/sql tables and pl/sql records. i need some working examples on pl/sql records and pl/sql tables from basics to hoghlevel.how to use then procedures and functions and packages.

i am new to pl/sql tables and pl/sql records. i need some working examples on pl/sql records and pl/sql tables from basics to hoghlevelThere is no such thing as PL/SQL "+tables+". This is a misnomer and creates the perception that a PL/SQL "table" is somewhat like a SQL table. Nothing can be further from the truth. The correct term is "+collection+" or "+associative array+". Compared to SQL tables, these are very primitive structures, very rigid structures, cannot scale, and can be quite expensive memory wise.
That is not to say do not use an associative array or collection. These are very useful tools.. but only when applied correctly. Like using a collection for a bulk fetch to transfer more rows between the PL and SQL engines and thus decrease context switching.
Unfortunately, quite often we see the row-by-row and slow-by-slow approach - where the developer uses SQL as an I/O only layer, pulls rows into expensive PL engine memory into record structures and arrays, and then process the rows there.
So before looking at working example (even the wrong approach's code will compile and run and work in practice), make sure that you know the fundamentals of correctly using the PL engine and correctly using the SQL engine. And these fundamentals can be summed up into a very basic rule:
Maximize SQL. Minimize PL/SQL+
Get this rule right, and you will have a sound foundation for writing performant and scalable Oracle applications.

Difference between empty plsql record and null plsql record

Hi there,
I am kinda getting confused with empty plsql record and null plsql record.
How do I assign plsql record to be empty and to be null?
create type emp_obj as object (enum number, ename varchar2);
CREATE OR REPLACE TYPE emp_type AS TABLE OF emp_obj;
Thanks

First of all, do not use term PL/SQL record in this context. Record type in PL/SQL is completely different from object type. Secondly, there are 2 states of a nested table:
1. Unintialized:
SQL> create or replace
2    type emp_obj_type as object(enum number, ename varchar2(10));
3 /
Type created.
SQL> create or replace
2    type emp_tbl_type as table of emp_obj_type
3 /
Type created.
SQL> declare
2      v_emp_tbl emp_tbl_type;
3 begin
4      v_emp_tbl.extend;
5 end;
6 /

DB Connect DataSource PSA records and DSO records are not matching...

Dear All,
I'm working with SAP NetWeaver BW 7.3 and for the first time, I have loaded from Source System DB Connect. I have created a DataSource and pulled all records and found 8,136,559 records in PSA. When I designed and created DSO with Key Fields 0CALDAY, Item No and Company Code, it has transferred records about 8,136,559 and added records about 12,534 only. Similarly following InfoCube has about 12,534 records into its Fact table. When I tried to reconcile the data/records with source DBMS for a month, the records/data could not matched?
1. What could be the reason behind the issue? why I am unable to load the records/data correctly?
2. Have I not mentioned the Key Fields of DSO in a correct manner?
3. Is it possible to load the records/data into DSO without giving any field as Key Fields?
4. How should I resolve this issue?
5. Is it could be of DSO Overwrite and summation function utilization if yes, then how to utilize it?
Many thanks,
Tariq Ashraf

Dear Tariq,
1. What could be the reason behind the issue? why I am unable to load the records/data correctly?
Ans: Check transformation once. Is there any start routine you have used or direct assignments. What kind of DTP settings you have done.
Check the messages at the DTP monitor. You will surely find some clue. Any duplicate records are being detected or not check once if you are using semantic keys in your DTP.
2. Have I not mentioned the Key Fields of DSO in a correct manner?
Ans: The transformation key and the DSo key are they same in your case?
What kind of DSO is it? Like for sales order DSO you take Order number as a key field., So you have to define the key fields according to business semantics I suppose. Do you agree?
3. Is it possible to load the records/data into DSO without giving any field as Key Fields?
Ans: I dont think so as the keys you defined will help in having unique data records isnot it?
4. How should I resolve this issue?
Ans: Please check the above as in Ans:1 please share your observation.
5. Is it could be of DSO Overwrite and summation function utilization if yes, then how to utilize it?
Ans: DSO overwriting of key figures is useful when you have full loads in picture. Are you always going to perform full loads ?
For reference would you like to check this thread: Data fileds and key fields in DSO
Lets see what experts give their inputs.
Thank You...
