Functions Pipeline Table with other tables using

I'm on DB 11.2.0.2 and used sparingly in pipeline table functions, but plans to arrays for a project that has a pretty big (many lines). In my tests, selecting from the table in pipeline perform well enough (if it's directly from the table pipleined or the view from above, I have created). Where I start to see some degregation when I try to join the tabe in pipeline discovered at other tables and add where conditions.

SELECT A.empno, A.empname, A.job, B.sal

OF EMP_VIEW A, B OF THE EMP

WHERE A.empno = B.empno AND

B.Mgr = '7839'

I've seen articles and blogs that mention this as a matter of cardinality and offer some undocumented methods to try to fight.

Can someone please give me some tips or tricks on this. Thank you!

I created a simple example using the emp table below to help illustrate what I'm doing.

DROP TYPE EMP_TYPE;

DROP TYPE EMP_SEQ;

CREATE OR REPLACE TYPE EMP_SEQ AS OBJECT

(EMPNO NUMBER (10),)

ENAME VARCHAR2 (100),

VARCHAR2 (100)) WORK;

CREATE OR REPLACE TYPE EMP_TYPE AS TABLE EMP_SEQ;

FUNCTION to CREATE or REPLACE get_emp back EMP_TYPE PIPELINED AS

BEGIN

TO heart (SELECT IN

EmpNo,

Ename,

job

WCP

)

LOOP

PIPE ROW (EMP_SEQ (cur.empno,

cur. Ename,

cur.job));

END LOOP;

RETURN;

END get_emp;

create or REPLACE view EMP_VIEW select * from table (get_emp ());

SELECT A.empno, A.empname, A.job, B.sal

OF EMP_VIEW A, B OF THE EMP

WHERE A.empno = B.empno AND

B.Mgr = '7839'

The ability to join would give me the most flexibility.

Pipelines can be attached. But here is the PL/SQL code - no tables. And without index.

Consider a view:

create or replace view sales_personel in select * from emp where job_type = 'SALES '.

And you use the view to determine the sellers in department 123:

Select * from sales_personel where dept_id = 123

Oracle considers that logically the next SQL statement like her can be pushed in the view:

select * from emp where job_type = 'SALES' and dept_id = 123

If the two columns in the filter are indexed for example, he may well decide to use a fusion of index to determine what EMP lines are dirty and department 123.

Now consider the same exact scenario with a pipeline. The internal process of pipelines are opaque to the SQL engine. He can't say the internal code pipeline "Hey, don't give me employees service 123".

He needs to run the pipeline. It must evaluate each channeled line and apply the "dept_id = 123" predicate. In essence, you must treat the complete pipeline as a table scan. And a slow that it take more than a simple disc lines when you perform the transformation of data too.

So yes - you can use the predicates on the pipelines, can join them, use analytical SQL and so immediately - but expect it to behave like a table in terms of optimization of SQL/CBO, is not realistic. And pointing to a somewhat flawed understanding of what a pipeline is and how it should be designed and used.

ORA-04091: table DSAMSTRC.T is mutating, trigger/function may not see it

My solution was to do a slider and update record row by row, but I was wondering if there is a way around this error?

Here's my example

   LOOP
      PIPE ROW (t_table_type (EACH.id, EACH.txt));
   END LOOP;

   RETURN;

---------------------------------------------------------------------------------------

UPDATE t
   SET txt = 'B'
 WHERE id IN (SELECT id FROM TABLE (get_t_array ('A')));

You can create a global temporary table that has the same columns that use your function to insert in there, and then use it to update t.

CREATE GLOBAL TEMPORARY TABLE t_temp
(id    INTEGER,
 txt  VARCHAR2(100))
ON COMMIT DELETE ROWS;

INSERT INTO t_temp
  (SELECT id, txt FROM get_t_array('A'));

UPDATE t
   SET t.txt = (SELECT txt FROM t_temp
                 WHERE t_temp.id = t.id)
 WHERE t.id IN (SELECT id FROM t_temp);

parallel in pipeline table function
Hi all

To "allow the parallel pipeline" table function, what I need to turn a query parallel session first?

I read a few white papers or web pages on map and reduce implemented with function table Oracle and see that, based on the table.

Use the cursor in the loop to get a line, run out! This replaces SQL pl/sql.

What is the cost that must be paid according to the table?

Finally, how can I confirm that Oracle has put the table function in parallel?

Best regards

In my application, I wrote stored procedures that return a collection of user-not of the types of objects to Java.

Flawed approach using memory expensive private server (PL/SQL PGA) caching SQL data and then push this data to the client - when the customer can use instead the more scalable and higher shared cache buffer memory instead.

With the types of objects, we can remove most of the redundent data.

This statement makes no sense that it is the same for SQL and sliders. And remove redundant data is preferable to the SQL itself - through partitioning engine pruning, predicates, only by selecting the columns there is place for the projection of SQL and so on.

This OO design reduces the load on the network and makes it easy for Java to parse.

Incorrect answer. It does not reduce network load - it can actually increase. Regarding Java 'parsing' - it's wrong from the beginning approach if the customer is required to analyze the data it receives from the server database. The analysis requires time CPU. Many average general processor muscle which will degrade the performance of analysis.

You may be using the analysis out of context here? Find it me hard to believe that one could design an application and use a server database in this way. The analysis of means for example to receive XML data (text) and then he analysis in an object - like structure for use.

Data of the database must be recovered by the customer in a binary structured format and not in a free format that requires the client to analyze in a structured format.

But the problem is that we accumulate all data in memory first and push them to the client as a whole. If it's too huge, ORA-22813 occurs.
This is why I intend to use the table of piplelined function.

How that will solve the problem?

As I followed your logic:
(1) you do not use the cursor for some obscure (and probably completely unjustified) reason.
(2) you may not return large collection PL/SQL variables without significantly dent PGA (process private memory) on the server and running into errors (this approach is conceptually incorrect anyway)
(3) you are now using an array of pipeline that executes PL/SQL code to execute SQL code - and in turn must be executed by the client as a SQL using a slider

So why put all the other moving parts (the pipeline code) between the two when the customer
(a) must use SQL to access?
(b) create a cursor?

If, as you say, I returned a cursor, it would be very difficult for Java organize data.

A table of pipeline must be able to be used through a cursor. All the DML statements from a client by Oracle are analyzed as cursors.

Read the language PL/SQL Oracle® Database reference guide section on ' + chaining Pipelined Table Functions for Multiple Transformation + ".

The format using a pipeline is (from the manual):
```
SELECT * FROM TABLE(table_function_name(parameter_list))
```
The "+ pipeline + ' is created by the SQL engine-, he need SQL to execute the PL/SQL code via the function TABLE() SQL.

You said that the reason to use a pipeline transforms a structure of relational data stored in a structure of the object. You don't need a pipeline for it. Plain vanilla SQL can do the same thing, without the fixed costs of use PL/SQ, SQL data recovery and change within the pipeline between PL/SQL and SQL context engines.

You simply call the constructor of the class of object in the projection of SQL and the cursor SQL returning the instantiated objects. For example
```
create or replace type TEmployee is object(
 .. property definitions ...
);

create or replace type TEmployeeCollection is table of TEmployee;

select
  TEmployee( col1, col2, .., coln ) as EMP_COLLECTION
from emp
where dept_id = :0
and salary > :1
and date_employed >= :2
order by
  salary, date_employed
```
No need for PL/SQL code. No need for a pipeline. The client will open the cursor and extraction of objects in a collection. The same approach that the customer would have used during extraction of a cursor on a table of pipeline function.

Pipelines are best used as a process of transformation of data where only SQL cannot perform the transformation. I never in many years of design and writing applications used Oracle PL/SQL pipeline into production on a SQL table. Simply because the SQL itself is capable and powerful enough to do the job - and do it faster and better.

I used pipeline is to transform the data from external sources into sets of SQL data. For example, a pipe on a web service. When the code PL/SQL of the constructions of the SOAP envelope, the HTTP call, analyzes the XML and returns the content in form of lines and columns - that allows to run a SQL SELECT on web-service-turned-into-a-SQL-table.

If you'd told me that Leon - it seems to me that your approach is a typical approach to Java that has very little understanding of the concepts of database and Oracle databases. You can't deal with Oracle as a simple persistence layer. You can't treat SQL and PL/SQL as a simple i/o interface for the extraction of data from Oracle and grinding that in Java. Not if you think that your system to run Java and scaling.

Rethink the Oracle layer, use properly - and your application will occur and will scale. Guaranteed.

However, from my experience, many J2EE developers choose to treat the Oracle as a black box, not further that a kind of file system loaded to store structured data and try to do it in the Java layer. And this fail. And I saw him failing - of the jaw dropping kind epic failures (knocking all the national newspapers and media as a result and an impact on ordinary people who have to deal with the Government).

And it's a shame... SQL and PL/SQL are superior to Java in this regard and are the layers much more able to cope and a power of data in the database. Example of the real world - largest table in our busiest database develops between 350 and 450 million lines per day and all our calculations of the data in this table is inside the database layer - and not in a layer of Java. Oracle performs and scales beautifully... when used correctly.

Pipelined table vs ref cursor in a function return
Hi gurus,

Everybody has discovered that a (subject) is faster on the other? Data will be primarily consumed from an external application (.net). What are the benefits? I can't decide if that use is

Thank you very much.

Thank you very much.

They are two different things.

A pipeline table acts as an array, but you must always choose in it and so if your consumption that in .net, you would still use a Ref Cursor I guess to query this table in pipeline (I guess .net is not query the tables directly, but must use some sort of slider Ref?)

Tables in pipeline can be fast, but it depends on what you need to. Is there a reason why you really need a feature in pipeline? If this is not the case, just use a normal query with a Ref Cursor, so your .net application only retrieves the data properly.

Pipeline table functions

I try to use the table double tube function. However, I need help to understand how... I understand, the pipeline table functions do not wait for the function ends and begins to return the data as soon as it gets. The calling program can continue the treatment rather than wait. Does this program calling both functions work in parallel table?

The calling function must still wait for all of the lines to be processed it just means that it can start to view until all rows are returned. It will not automatically put the function as a kind of stand-alone function that runs in the background lines back.

Example:

You may need to return 100,000 rows

A pipeline function will return 1-5 000 from 5 000 are returned.

If you are returning a collection but don't not the processing pipeline, it must wait until all the 100,000 lines to collect and send everything at once.

A useful case of this pagination, or you want a user to see the first rows quickly since 99% of the time they will not be the page of the second series.

The ALL_DEPENDENCIES view has hierarchical information based on object_id

The view object has the object_type.

Create a hierarchical query on the first view and attach it to the second view.

Or you can use the utldtree.sql file in the installation of the DB admin folder. Comments initially show you how a hierarchical query based on the object type.

Implementation of the functions of table (indexOf, lastIndexOf, removeDuplicates...)

Hello
I'm trying to implement some functions to manipulate tables more easily, as I would with other programming languages (Array.IndexOf exists in Javascript, but seems to be absent from ExtendScript).
First of all, I tried to add these functions using Array.prototype; Here's what I've done for two of these functions:
```
Array.prototype.indexOf = function (value)
        {
          for (var i = 0;i<this.length;i++)
            {
                if (this[i] == value) return i;
            }
            return -1;
        }
       
Array.prototype.removeDuplicates = function ()
        {
            var removed = [];
            for (var i = 0;i<this.length-1;i++) {
                    for (var j=i+1;j<this.length;j++) {
                        if (this[i] == this[j]) {               
                            removed.push(this.splice(j,)1);
                        }
                    }
                }
                return removed;
        }
```
It seemed to work fine, but I discovered that it breaks this kind of loop:
```
for (var i in array) {
     alert(array[i]);
     }
```
The loop through the values in the table and continues beyond array.length with the features added to the prototype.
As explained here, I have found a workaround, using Object.defineProperty () rather than implement functions in Array.proptotype
```
Object.defineProperty(Array.prototype, "indexOf", {
  enumerable: false,
  value: function(value) {
      for (var i = 0;i<this.length;i++)
            {
                if (this[i] == value) return i;
            }
            return -1;
    }
});
```
But... Object.defineProperty () is missing in ExtendScript too!
I don't know what to try next... Any idea?
Thank you!

The primary reason that some of these functions do not exist, is that ExtendScript is based on the ECMA-262 standard. Very old JavaScript and I don't think all this is implemented.

PG. 3 of the CS6 script guide (only written comprehensive guide Adobe has for the moment) after effects Developer Center | Adobe Developer Connection:

The ExtendScript language

"After Effects scripts using the Adobe ExtendScript language, which is an extended form of JavaScript used by several applications Adobe, including Photoshop, Illustrator, and InDesign. ExtendScript implements the JavaScript language according to the ECMA-262 specification. The After Effects script engine supports the 3rd edition of the ECMA-262 standard, including its conventions of notation and lexical, types, objects, expressions, and statements. ExtendScript also implements the E4X ECMA-357 specification, which defines the access to the data in XML format. »

Even though I know that many developers have made prototyping, I found it to be annoying personally, especially if your code moves outside your machine. I just made autonomous functions for all my scripts. It has been easier to reuse code and create some (not all) missing features that would be nice to have the day current Javascript.

XML data in the table using sql/plsql

Hi experts,
Could you please help with the following requirement. I have the tags xml (.xml on a server file) below. I need to access this file and read the XML and insert into the db table using sql and plsql. Is it possible with the cdata below? And there is a nested this table.
Could someone please guide me if you have a sample code file and xml.

Of course, you'll want to change the types of data, etc. as needed.

I assumed that the XML can contain several "" sections and that each section can contain several entries.

Thus the XMLTABLE aliasing as 'x' gives information of XML, and supplies the data associated with the XMLTABLE with alias 'y' which gets the multiple authors, which itself section of the XMLTABLE with alias 'z' for each of the article_item.

CDATA stuff are handled automatically by SQLX (XML functionality integrated into Oracle's SQL)

Normalize the names in a huge table using UTL_MATCH

Hello
I have a large table (350 million records) with a "full name" column
This column has a few typos, so I have to 'normalise' the data (only for this column), using UTL_MATCH. JARO_WINKLER_SIMILARITY.
I did some tests with a small table, and it works to show the similar names:
SELECT b.SID, b.name FROM typotable a, typotable b utl_match.jaro_winkler_similarity (b.SID, b.name) WHERE BETWEEN 85 and 99 AND a.rowid > b.rowid;

But:

(1) the test table was small, by using this code directly on the 350 million accounts table take ages... What can be done about it?

(2) this shows just the similar names. How can I update the table by searching for similarities, choose one of them as the only value for each name?

Thank you

Yes, I get your point. The thing is that there is no "correct" available names and the original table is huge, that's what I thought:

-Create a table of secondary NAMES, with unique names. These names would have been generated by match the values similar to one of them (but always the same, no matter if is not one that suits). This should be equivalent to your table 'correctness '.

-Run the cleaning procedure for updating records

How can I create this secondary NAMES table? (The column 'genre' is not serious at all, that the 'name' must be set)

Thanks for your help

Well, you need to determine what is the logic that would pick one of the incorrect names on the other. In its current version, you can easily get two incorrect values having the same value of match. But then you must also consider what creates a 'group' of values that you can get the best in the group. Using the match itself is not enough to create groups.

Example:

SQL > ed

A written file afiedt.buf

1 Select a.fname as $fname1, b.fname as fname2

2, utl_match.jaro_winkler_similarity (a.fname, b.fname) as a match

3 typotable one

4 join typotable b on (a.fname! = b.fname)

where the 5 utl_match.jaro_winkler_similarity (a.fname, b.fname) > = 85

6 * 1.3 desc order

SQL > /.

As you can see, for example, FROCEN has two possible variants, both with a football match of the 92. The same with others.

However, you could start cutting things around (and it's really a hack) to get something like:

Cascade of two functions of table build - what happens?

I found the code indicated in the attachment in a very complex VI that I'm rehabilitated. Could someone explain what is happening with the functions of table build "cascade".

I see that the first function to build array built a table 1 d of integers that passes to the second function to build table that shows a table 2D of integers, but since there is no element or second input array, I don't see how it works.

This is part of a Subvi, which is not incorporated into a loop.

All the examples have at least two entries. There is no option to concatenate entries with a single entry. There is an implicit operation here that I don't understand.

If someone explain how it works?

You're taking a scalar value and creating a table 1 d with exactly 1 element.

So you're taking 1 d table and build in a 2D, with exactly 1 Item table.

Since you can't concatenate something with nothing, only logical mode for the table build would be to build in a table of the next larger size.

You could add a third, then you'd have a table 3D with exactly 1 element. And so on.
