When to use nested Tables vs Varrays
Nested tablesWhen data must be stored in a database table
When the size of the data cannot be predefined i.e. the collection / data container must be dynamic
When the dml operations should be made on individual items in the column.
VARRAY
When the number of elements are predefined
When data must be stored in the database
But when it comes to performance
Please can anyone suggest some example scenario in which case it is best to use one of them and why.
Thank you.

I tried to create a function that might return the type that is created on the outside.

Why the hell use nested tables?
Hello
I'm boning up on top of the PL/SQL (again) waiting to get a new job.
I have several years of experience in various roles related to the data, including many used Oracle.
On the issue of collections, I ask myself, in light of my experience, to find and not for the first time, why the hell would anyone want to do this:
I really, really, can't think why we want to store data like that. It seems unnecessarily complex, hiding a one-to-many relationship inside TEST_TABLE, which should rather be modeled and implemented as a separate table.create or replace type TEST_TT as table of varchar2(10); / create table TEST_TABLE ( X number ,Y test_tt) nested table Y store as Y_TABLE;
In addition, there are a lot of tutorials on the collections that tell us how to do the above (in fact I read Feuerstein right now), but nobody seems to tell us WHY we should do it.
Can someone help me out here?
Thank you.
JasonI can't imagine wanting to create a table like this one either (or, if this can help, can Tom Kyte).
The collections are terribly useful in PL/SQL, when they help you avoid one treatment per line. I can't imagine wanting to integrate into my data model. Frankly, it's much the same with the types of objects - they are quite useful in PL/SQL, but I would never want to create a table in my data model that contained an object.

Can you attribute programmatically size when you use the table in the Cluster service cluster
I use the table of the Cluster service. The only way I know to the size of the cluster is to right click on the function and set the Cluster size. But what happens if the length of my table changes? Is there a way to make the cluster size is the number of elements in the table? Seems like labview should do this automatically at run time. There may be some nodes of property I don't know.
I tried the SQL statements, but it always boils down to having to know the number of columns is in the database prior to execution.
What I did to generate the object to be a cluster to match database fields. My recordset is an array of objects. Then I a vi member to build a recordset from the database and another Member vi to retrieve an array of clusters of the recordset object. If the database changes, I have to change the subject and these two vi. All the other Subvi call these two for the manipulation of data. No other sub - VI have bundle and ungroup functions in them, only the vi of two members. Thus a change in the database requires a change of control and two vi. Not too bad.

How do I get the number of incorrect records when you use external tables
Hi all, I have an external table DEPT,.
DEPT. DAT
20. ELECTRONICS
10. SHOES
30. CAMERA
Select * from the Department; only 10 and 30 dept will be led as deptdescr for 20 that there are more than 10 in length so this record will go into the wrong file,
y at - it count any query to display the folder or get any query to get the record to view the entries entries wrong file rather that will drop and see how much is rejected.

When you use the table of contents
A few questions
Can I do the button contents of larger. Currently, the arrows are not useful to the partially overview
I can move the TOC button to another location. say at the bottom of the page
Is it possible to put a button until you see the table of contents
Is it going to rain tomorrow
What makes my wife tea tonight
Hello Devon,
However, I know that's not possible. The button table of contents is generated only generated at run time and has not yet been exposed to the Skin Editor TOC UI. If like me you want to it see the ability to customize it in a future version of Captivate so please add your voice by presenting this as a feature request.

Nested tables will not align with the primary table
Hi all. Looks like I am facing another obstacle focus on the table. While I was creating one of my pages, I used nested tables to create a column on the left side of the page that will contain my menu secondary, while the other column will hold a flash element and the content of the page.
Although I have inserted tables nested with a spacing of the cell '0' and '0' cell padding and Visual AIDS seem to indicate that the values in the nested table are identical with the primary table who is the holder, the nested table that will contain the film and the page content is not embedded with the table above. It seems to be off by 1-2 pixels or more, but since there will be a right on the image under the menu is quite obvious.
I enclose the code for your information (line 165, 166).
Thank you for your time and your suggestions. I really appreciate it.

nested table disappears in design mode
Hello
Sometimes, when I have nested tables, the intimate table disappears in Design view. The table looks fine in a browser, however. Anyone know what is happening?
Thank you!The technical term is that the syntax of table is horked.
After detached the model, there are tons of tags highlighted in yellow

How can you add item (object) complex "nested table"?
Hello I did some reading on * "Associative" * and * "Nested Table" * and I would like to enumerate the collection using the later version (http://www.devshed.com/c/a/Oracle/Database-Interaction-with-PLSQL-Nested-Tables/2/)
-know list "Nested Table"
However, encountered problem try to * 'EXTEND' * my nested table (add items to the complex type or OBJECT I defined, namely 'TmpHierarchyMapObjType' below) - detail as follows:
-NOTE 1: Here's how to create the type object (be well if I just say "CREATE or REPLACE TYPE TmpHierarchyMapObjType AS OBJECT (_TMP_HIERACHICAL. ROWTYPE_)"instead of having to duplicate the column definition.
CREATE OR REPLACE TYPE TmpHierarchyMapObjType AS OBJECT
(
ID numeric (19.0),.
ParentId numeric (19.0),.
ChildId numeric (19.0),.
...
TmpUID varchar2 (32),
ReferencedId numeric (19.0),.
...
);
-NOTE 2: I can't put 'TmpHierarchyMapObjType' inside the package, but it's not crucial, I guess.
Types of CREATE or REPLACE PACKAGE
AS
TYPE cursorType IS REF CURSOR;
TYPE TmpHiearchyMapTableType IS TABLE OF THE TmpHierarchyMapObjType; / * Use 'Nested Table' instead of an associative array * /.
/ * TYPE TmpHiearchyMapTableType IS TABLE OF THE TMP_HIERARCHYMAP % ROWTYPE INDEX DIRECTORY. */
END;
-NOTE 3: Here is my FUNCTION TABLE that now returns a "Nested Table" as assumed to 'Associative' (with a syntax different enumeration)
FUNCTION to CREATE or REPLACE spGetParentsTable
(
Number to the ObjectId,
ObjectClassifier varchar2
)
RETURN types . TmpHiearchyMapTableType -now a 'Nested Table', not 'voluntary '.
IS
Types of TmpHierarchyMap. TmpHiearchyMapTableType;
ThisTempId varchar2 (32);
CURSOR spGetParents_cursor IS
SELECT
ReferencedId Id,
ParentId,
ChildId,
...
OF TMP_HIERARCHYMAP
WHERE TmpUID = ThisTempId;
BEGIN
SELECT sys_guid() IN the double ThisTempId;
spRecursiveGetParents (ObjectId, ObjectClassifier, ThisTempId);
-(Commentary) TmpHierarchyMapMAX: = 0;
FOR oMap in spGetParents_cursor LOOP
-(Commented out) TmpHierarchyMapMAX: = TmpHierarchyMapMAX + 1;
-QUESTION: FAILED here! How can I add/elements of complex types?
TmpHierarchyMap.EXTEND (cast (oMap as TmpHierarchyMapObjType));
/*
NOTE: (In the comment) use is not "Associative", now using "nested table" instead.
TmpHierarchyMap (TmpHierarchyMapMAX). ID: = oMap.Id;
TmpHierarchyMap (TmpHierarchyMapMAX). ParentId: = oMap.ParentId;
TmpHierarchyMap (TmpHierarchyMapMAX). ChildId: = oMap.ChildId;
...
*/
END LOOP;
DELETE FROM TMP_HIERARCHYMAP WHERE TmpUID = ThisTempId;
RETURN TmpHierarchyMap;
END spGetParentsTable;
-Finally, I would like to enumerate the nested table.
DECLARE
types of oMappingTable. TmpHiearchyMapTableType;
BEGIN
oMappingTable: = spGetParentsTable(2,'ThinkFundamentals.Util.Security.SystemUser');
-NOTE 4: this is my final goal!
Select * from table (cast (oMappingtable as types.) TmpHiearchyMapTableType));
dbms_output.put_line ('done!');

ORA-01789 - when you use the operator of TABLE and SEM_MATCH
Client version: 11.1.0.7 on Windows 7 (32 bit)
Server version: 11.2.0.3 on Windows 7 (64-bit)
I am model prototyping a simple RDF, and I'm getting a ' ORA-01789: block has an incorrect number of columns in query results "when you use the SEM_MATCH with the SCOREBOARD operator.
I can run this:
and the first line is:select id, a.triple.GET_TRIPLE() from drik.rdf_data a
Now, I want to use the TABLE like this:(<http://www.ihc.com/drik/term#2>, <http://www.w3.org/2000/01/rdf-schema#subClassOf>, <http://www.ihc.com/drik/term#1>)
But this performance gives the ORA-07189. Even try SELECT * gives the same error.select c from table(sem_match('{ <http://www.ihc.com/drik/term#2> <http://www.w3.org/2000/01/rdf-schema#subClassOf> ?c . }', sem_models('Prototype'), sem_rulebases('RDFS'), sem_aliases(sem_alias('rdfs','http://www.w3.org/2000/01/rdf-schema/')), null ))
I expect to get a refund:
How should I approach troubleshooting this?<http://www.ihc.com/drik/term#1>
Thank you, SteveThanks for posting the script. I was able to reproduce the error locally.
The problem is the use of the sem_apis.create_rules_index () procedure, which has been deprecated:
http://docs.Oracle.com/CD/E11882_01/AppDev.112/e25609/sdo_rdf_newfeat.htm#autoId26Please use sem_apis.create_entailment () instead, and the error should disappear.

How to get a 'white' answer when you use 'if' statements in a table
I use a table for an invoice where an element is classified, but more can be shipped as ordered. I have figured out formcalc expression where I can get a 0 in the column "out of stock" If the delivered quantity is more than the ordered article, but I can't get rid of a value of 0 in the rest of the column out of stock when all information "shipped" columns "orderly" and. Try to get this column blank if there is no order or shipping information.
So far, it works for the math part. Don't know how to write an 'empty' in the calculation
Sum(ordered-shipped)
If (Sum(ordered-shipped) > 0)
then backordered = Sum(ordered-shipped)
ElseIf (Sum(ordered-shipped) < 0)
then out of stock = 0
endif
Any advice will be greatly appreciated. Thank you!
Have you checked the patterns listed for your numeric field in the object palette?
This could be the cause for the zero. I tried on my system local and if I assign null, he demonstrated an empty value.

Is it Possible to use a function when you create a table?
Hello
Is it possible to use a function during the construction of a table?
I would like to browse my data returned from the db and call a function. The part where I call the function "myFunction [i]" doesn't seem to work. How can I solve this problem? I need to put the function call results in the table.
var i: uint;
for (i = 0; i < dataArray.Length; i ++)
{
dgArray = [{name: dataArray [i] .name, Type: myFunction [i]}];
}
Thank you!-LaxmidiHi laxmi,
Yes of course it is quite possible to use a function when you create a table... In your code, you made some mistakes...
You used hooks to call the function myFunction [i]... where you are supposed to use parentheses... myFunc (i)... and other you must push the object in the dgArray but yous hould not not attribute...
dgArray = [{name: dataArray [i] .name, Type: myFunction [i]}]; This will result in only the last table iterates in dgArray...
So you should write dgArray.push ({name: dataArray [i] .name, Type: (i) myFunction});
Check out the code below...
private var dgArray:Array = new Array();
private var myDataArray:Array = [{data: '1', name: 'Robert'}, {data: '2', name: 'Nicolas'}, {data: '3', name: "Bika"}]
private function init (): void
{
for (var i: int = 0; i
{
dgArray.push ({name: dataArray [i] .name, Type: (i) myFunction});
}
}
private void myFunction(i:int):String
{
Return 'Type' + i;
}

Bad performance on a table partitioned range when you use sysdate
I have a partition table with a DATE partition key column.
Tables servs as a sliding window this is by adding a new partiotion for each day and dropping out of the older partitions.
Each week, I generate a weekly report:
SELECT... FROM MaTable WHERE part-key-column > SYSDATE-7;
This query runs for about 5 hours
When you use a hardcoded hard 'day' the query is finished about 4 times faster
SELECT... FROM MaTable WHERE part-key-column > TO_DATE ('20100211', 'YYYYMMDD');
any suggestion?

How to fill the value in the nested table by using the object type
Hi gurusI 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.
Code example
CREATE or REPLACE TYPE countries_o
AS
OBJECT
(
COUNTRY_ID TANK (2 BYTES),
COUNTRY_NAME VARCHAR2 (40 BYTE),
REGION_ID NUMBER);
/create or replace type countries_t is table of the countries_o;
/CREATE OR REPLACE
ABC of the PROCEDURE
IS
v_print countries_t; -: = arr_countries_t('01','Aus',1);
BEGIN
v_print: = countries_t('01','A',11);
DBMS_OUTPUT. Put_line (v_print. COUNTRY_ID | v_print. COUNTRY_NAME | v_print. REGION_ID);
END;
/
Error
- Error (6.3): PL/SQL: statement ignored
- Error (6,12): PLS-00306: wrong number or types of arguments in the call to 'COUNTRIES_T '.
- Error (7.3): PL/SQL: statement ignored
- Error (7.32): PLS-00302: component 'COUNTRY_ID' must be declared
Thanks in advance
Concerning
Muzz
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
