Referenced table datatype

hi
i need to change a datatype in a field referenced. i have 10 tables.
I try with:
ALTER TABLE DM08_PERSONA MODIFY CONSTRAINT FK_DM08_PER_FK_PERSON_DM08_BAS DISABLE NOVALIDATE;
ALTER TABLE DM08_PERSONA MODIFY CONSTRAINT FK_DM08_PER_FK_PERSON_DM08_BAS DISABLE VALIDATE;
ALTER TABLE DM08_PERSONA MODIFY CONSTRAINT FK_DM08_PER_FK_PERSON_DM08_BAS DISABLE;
one for every table and it works fine; the tables were altered.
But when i try to change the datatype i still have the error ora:02267 datatype incompatible.
Any ideas or suggestions. Thanks a lot.

What datatype you are changing TO and FROM?
Is the table empty?
All your alter statements are against one table only, why you are disabling the constraint 3 time in different ways (validate.novalidate etc)?

Best practice: self referencing table

Hallo,
I want to load a self referencing table to my enterprise area in the dwh. I am not sure how to do this. What if a record references to another record which is inserted later in the same etl process? There is now way to sort, because it is possible that record a references to record b and record b references to record a. Disabling the fk constraint is not a good idea, because this doesn't prevent that invalid references will be loaded? I am thinking of building two mappings, one without the self referencing column and the other only with it, but that would cause approx. twice as much running time. Any other solutions?
Regards,
Torsten

Mind sharing the solution? Would be interested to hear your solution (high level).

Ms sql - {"The referenced table must have a primary or candidate key. [ FK Name = ForeignKeyB_Details ]"}

I have a txt file which has all the sqltext in it separated by semi colon .Then I try to run a query one by one like this-
var conn = new SqlCeConnection(ConnectionString);
conn.Open();
var cmdArray = Regex.Split(sqlText, ";");
var cmd = new SqlCeCommand(null, conn);
foreach (var text in cmdArray)
cmd.CommandText = text;
if (!text.Equals(string.Empty))
cmd.ExecuteNonQuery();
else
break;
conn.Close();
I get the error {"The referenced table must have a primary or candidate key. [ FK Name = ForeignKeyB_Details ]"}
here is part of my txt file-
CREATE TABLE A
PrimaryId nvarchar(10) NOT NULL REFERENCES C(PrimaryId),
UserId nvarchar(20) NOT NULL,

Hi,
Foreign key columns are frequently used in join criteria when the data from related tables is combined in queries by matching the column or columns in the FOREIGN KEY constraint of one table with the primary or unique key column or columns in the other table.
For more information about the foreign key constraint, please refer to this link:

Self Referencing Tables...

I have a self-referencing table (a Topic can be a response to another Topic) and read one of Frank Nimphius' blogs on this subject, posted on the ADF board for advise. As a result I created the read-only ViewObject to set up this tree relationship and set it to be exposed to the App Module.
Do I need to do more to it than that for JHeadstart to generate the right page defs? Any advise on setting this up cleanly? My user interface must present a page in which users can post new Topics, view topics in a heirarchy (response thread, like in this forum) and respond to Topics or responses. A response is a Topic that references another (parent) Topic. I have to believe this has been done before a million times but am not sure myself how to do it.
Thanks!

Steve,
I've read the section and am getting this error:
(oracle.jbo.SQLStmtException) JBO-27122: SQL error during statement preparation. Statement: SELECT Topic.SUBJECT, Topic.ROW_ID, Status.STATUS_CHOICE, Status.ROW_ID AS ROW_ID11, Topic.CREATED_BY, Topic.CREATION_DATE, Response.SUBJECT AS SUBJECT1, Response.CREATION_DATE AS CREATION_DATE1, Response.ROW_ID AS ROW_ID12, Response.CREATED_BY AS CREATED_BY1 FROM TOPIC Topic, RESPONSE Response, STATUS Status WHERE (Topic.ROW_ID = Response.MASTER_ID (+)) AND (Topic.TOPIC_STATUS_ID = Status.ROW_ID) CONNECT BY PRIOR Topic.ROW_ID = Response.MASTER_ID (+) OR Response.ROW_ID = Response.MASTER_ID (+) ORDER BY SUBJECT,CREATION_DATE1
----- LEVEL 1: DETAIL 0 -----
(java.sql.SQLException) ORA-01436: CONNECT BY loop in user data
I have a table called Topic with a Pk called ROW_ID and another table called Response with a Pk called ROW_ID and an Fk called MASTER_ID. A Topic can have many Responses and a Response can also have many Responses. The parent ID could point to either a Topic or a Response. There's no limit on how many levels this can continue. There's a Status table also from which I want to show the text value of the Status for the Topic row (not the Status ROW_ID)
I have a View Object including entities: Topic, Response & Status
I tried the SQL query as:
(Topic.ROW_ID = Response.MASTER_ID (+)) AND (Topic.TOPIC_STATUS_ID = Status.ROW_ID) CONNECT BY PRIOR Topic.ROW_ID = Response.MASTER_ID (+) OR Response.ROW_ID = Response.MASTER_ID (+)
Hoping to have this result:
Topic A
-Response A (to Topic A)
--Response B (to A)
---Response C (to B)
-Response D (to Topic A)
Topic B
Topic C
What am I doing wrong?
Is there a guide that explains better using JHeadstart with JDeveloper (rather than Oracle Designer, which we don't use)? The developer's guide for JHeadstart is hard to translate for use with JDeveloper...
Thanks!!

How to build query to get tree architecture of self referencing table

Dear all,
I have the following table design :
This is a self referencing table representing a set of SubCategories which can have parent sub categories or not. I did not show here the Category table.
If the Subcategory has the ParentSubCategory ID = null, then this is a root subcategory otherwise it is a child of a parent sub category.
What I am looking for is the easy way to display the structure level by ProductCategoryID ?
Thanks for helps

you can use a recursive logic based on CTE for that
something like this would be enough
;WITH ProdSubCat_Hiererchy
AS
SELECT psc.ProductSubCategoryID,c.CategoryName,psc.ParentSubCategoryID, psc.Name,CAST(psc.Name AS varchar(max)) AS [Path],1 AS [level]
FROM ProductSubCategory psc
INNER JOIN Category c
ON c.CategoryID = psc.ProductCategoryID
WHERE psc.ParentSubCategoryID IS NULL
UNION ALL
SELECT psc.ProductSubCategoryID,c.CategoryName,psc.ParentSubCategoryID, psc.Name,CAST(psch.[Path] + '/' + psc.Name AS varchar(max)) AS [Path],psch.[level] + 1
FROM ProductSubCategory psc
INNER JOIN Category c
ON c.CategoryID = psc.ProductCategoryID
INNER JOIN ProdSubCat_Hiererchy psch
ON psch.ProductSubCategoryID = psc.ParentSubCategoryID
SELECT *
FROM ProdSubCat_Hiererchy
ORDER BY LEFT([Path],CHARINDEX('/',[Path]+'/')-1),[Level]
OPTION (MAXRECURSION 0)

JPA: How to initialise an entity for a self-referencing table?

I am working on a project that requires a self-referencing table:
mysql> show create table attributes\G
*************************** 1. row ***************************
       Table: attributes
Create Table: CREATE TABLE `attributes` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`parent` int(11) DEFAULT NULL,
`type` int(11) DEFAULT NULL,
`name` varchar(128) DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `parent` (`parent`),
KEY `type` (`type`),
CONSTRAINT `attributes_ibfk_1` FOREIGN KEY (`parent`) REFERENCES `attributes` (`id`),
CONSTRAINT `attributes_ibfk_2` FOREIGN KEY (`type`) REFERENCES `attributes` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=26 DEFAULT CHARSET=latin1
I used NetBeans to generate an entity class from the table:
@Entity
@Table(name = "attributes")
@XmlRootElement
@NamedQueries({
    @NamedQuery(name = "Attributes.findAll", query = "SELECT a FROM Attributes a"),
    @NamedQuery(name = "Attributes.findById", query = "SELECT a FROM Attributes a WHERE a.id = :id"),
    @NamedQuery(name = "Attributes.findByName", query = "SELECT a FROM Attributes a WHERE a.name = :name")})
public class Attributes implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Basic(optional = false)
    @Column(name = "id")
    private Integer id;
    @Size(max = 128)
    @Column(name = "name")
    private String name;
    @OneToMany(mappedBy = "parent")
    private Collection<Attributes> attributesCollection;
    @JoinColumn(name = "parent", referencedColumnName = "id")
    @ManyToOne
    private Attributes parent;
    @OneToMany(mappedBy = "type")
    private Collection<Attributes> attributesCollection1;
    @JoinColumn(name = "type", referencedColumnName = "id")
    @ManyToOne
    private Attributes type;
    @OneToMany(cascade = CascadeType.ALL, mappedBy = "attributes")
    private Collection<ItemAttributes> itemAttributesCollection;
    @OneToMany(mappedBy = "ivalue")
    private Collection<ItemAttributes> itemAttributesCollection1;
But how can I write a constructor for this entity? The auto-generated code gets around the issue by doing nothing; the constructor is empty. I can't help thinking that if I set the parent and type references to anything with new Attributes(), then it will recurse out of control. What else can/shall I do? I know how to rewrite it to not use the entity relations, but I'd prefer to make it work.

I don't want to call the hash table creation method because from what i understand about interfaces the idea is that your main method doesnt know the table is actually a hash table...is that right?That's not exactly the idea. The idea to use the interface as the type instead of the implementation, is that your class probably doesn't need to know the full type. This makes it easy to change the implementation of the interface if needed. However, somebody at some point has to create the concrete object, a HashTable.
Basically, an interface describes a behavior, and a class that implements an interface decides how to actually perform this behavior. It is obviously impossible to perform the behavior if you are not told how to perform it.
Table table = new HashTable() is the correct way to do it. This means that if you ever need you Table implementation to change, the only thing you need to change in your whole class is this line. For example you might want Table table = new FileTable().

Query output help: Display self-referencing table

Hello,
I'm trying to display in a cfoutput a self-referencing table.
I'll start by showing some of the data in the table.
There are only 3 columns, pl_id (auto increment id pri-key),
pl_name and pl_parent_id (it's 0 if it's a parent, otherwise it's
the pl_id value for the parent).
pl_id pl_name pl_parent_id
1 Country 0
2 Food 0
3 US 1
4 Japan 1
5 Hamburger 2
6 Idaho 3
7 Florida 3
8 Cheese 2
What I'm trying to output is something like this:
Country - US - Idaho (3 levels here) or
Country - US - Florida (or if there are only 2 levels like
the next line)
Food - Cheese
I've tried using a cfoutput with a cfloop as well as grouping
but not having any luck. Could someone clear my clouded head on
this one?
thanks much,
Joe
ps. Adobe should really use a fixed width font for these
forums, it's impossible to line up table info!

Self referencing table many to many relationship

I am in a bit of a logic pickle, and I was wondering if someone could help me out.
I have a table in a database I am designing called document, it holds information on surprisingly on documents in our DMS.
I want to create the notion that a document can have multiple related documents, and those documents can be the related documents for many documents.
So it is a self referencing table, I have done these before so no big deal, but this time is a many to many relation, it wasnt before.
Maybe something like:
document
docid (pk)
related_doc
docid (pk) (fk to document.docid)
related_docid (pk) fk to document.docid)
Does anyone have any experience with this or any advise I might find sueful?
Thanks!

A junction table can be used to resolve a many-to-many relationship as is in your example. There are two PK/FK relationships between document and related_document table. This will prevent denormalization of data.
The other option could be to have just one table with two columns (parent_doc_id and child_doc_id) and have a PK constraint on both the columns - just like bill-of-materials.
But I think the approach you have in your posting will work well.

Self referencing table and SQL statement

In my database, I have a self-referencing table, the table itself is for projects, and it allows users to get a hierarchical view of the company.
Here is the SQL (modifier is the term we use for project code, BBCI is the top project)
SELECT
modifier, modifierDescription, level
FROM
modifier
WHERE
level <= 2
CONNECT BY PRIOR
modifier = parentModifier
START WITH modifier = 'BBCI'
ORDER BY level
That perticular query gets the first two levels in the structure. I use this information to produce a tree structure in a web app.
But users have requested it would be good if in the tree structure is showed an + or - depending on whether there were anymore children under each parent, or better still the number of children under it, for example
BBCI
+ BBCI_CHILD
+ BBCI_CHILD2
- BBCI_CHILD3
or
BBCI
+ BBCI_CHILD (3 projects underneath)
+ BBCI_CHILD2 (2 projects underneath)
- BBCI_CHILD3 (0 projects underneath)
I am really stumped on this issue, and I am sure there is a way to do this in the web app, so for example do a query for each child node to see how many child nodes are underneath, but I figure it would be a lot tidier and faster if I could do it from a single SQL statement. Unfortunately I have tried to do this and am very much stuck.
If you need more information please let me know
Thanks!
Jon

You may be able to do this using analytical functions but it depends on the Oracle version you are using. It can also be done with standard SQL - you just need to count the number of child rows for each modifier/project first and supply that list as an in-line view:
SELECT decode(modifier,'X',null,decode(child_rows,null,'-','+')),
m.modifier,
decode(modifier,'X',null,'('||nvl(cq.child_rows,0)||' projects underneath)')
FROM modifier m,
(select parentModifier,
count(parentModifier) child_rows
from modifier
where parentModifier is not null
group by parentModifier) cq
WHERE m.modifier=cq.parentModifier(+)
AND level <= 2
CONNECT BY PRIOR
m.modifier = m.parentModifier
START WITH modifier = 'X'
ORDER BY level, modifier;
which gives you something like...
D MODIFIER DECODE(MODIFIER,'X',NULL
X
- Y1 (0 projects underneath)
+ Y2 (2 projects underneath)
+ Y3 (3 projects underneath)
The decode stuff is just to show you the result, you can format the output in your calling code. Just extend the columns to include everything you want, modifierDescription etc..
Hope this helps.

Self referencing table and contraint

Hi,
I have a self referencing table, used to store information on projects in an organization. There is a pimary key (modifier) and a foreign key to the modifier field (parentModifier)
Note: (modifier = project in the organization)
Basically, the parentModifier cannot be equal to the modifier in the same table, or equal to any of its children, otehrwise you get wierd recursive relationships. Its like saying you cannot be your own father, or one of your children cannot be your father. To get a list of the modifiers the parentModifier cannot be, the following statement can be used:
select
modifier
from
modifier
where
modifier = 'A'
and
level >= 1
connect by prior
modifier = parentModifier
start with
modifier = 'A'
order by
level;
So, now, I guess the way to do this is perform that query in a trigger before each row is being updated, so the pseudo code would be something like:
BEFORE UPDATE ON modifier
FOR EACH ROW
DECLARE
modifierToChange varchar2(255);
modifierList ???;
BEGIN
select
modifier
into
modifierList
from
modifier
where
modifier = 'A'
and
level >= 1
connect by prior
modifier = parentModifier
start with
modifier = 'A'
order by
level;
if modifierToChange in modifierList
return error
else
execute query
end if
END
As you can see my PL/SQL is limitied. At the moment I can handle this at the application layer (in php), but if the admin going to SQL Plus and starts to fiddle, they can easy break the system, by setting an invalid relationship.
I was wondeirng, if anyone could give me some help or advice, it would be fantastic,
Thanks!

Having a unique key on mod_id would be enough to make sure the same element is not in the structure more than once. By allowing it to happed you will have all the descendants of the dup element following it when you walk the tree.
Let's say this is the intended behavior.
Consider the following test scenario:
create table modifier (
mod_id varchar2(10),
parent_mod_id varchar2(10)
insert into modifier (mod_id, parent_mod_id) values ('a', null);
insert into modifier (mod_id, parent_mod_id) values ('aa', 'a');
insert into modifier (mod_id, parent_mod_id) values ('ab', 'a');
insert into modifier (mod_id, parent_mod_id) values ('ac', 'a');
insert into modifier (mod_id, parent_mod_id) values ('aaa', 'aa');
insert into modifier (mod_id, parent_mod_id) values ('aab', 'aa');
insert into modifier (mod_id, parent_mod_id) values ('aac', 'aa');
insert into modifier (mod_id, parent_mod_id) values ('aba', 'ab');
insert into modifier (mod_id, parent_mod_id) values ('abb', 'ab');
insert into modifier (mod_id, parent_mod_id) values ('abc', 'ab');
insert into modifier (mod_id, parent_mod_id) values ('aca', 'ac');
insert into modifier (mod_id, parent_mod_id) values ('acb', 'ac');
insert into modifier (mod_id, parent_mod_id) values ('acc', 'ac');
insert into modifier (mod_id, parent_mod_id) values ('b', null);

Table 2 Cel A1 Referencing Table 1 Cel A1

Hi,
I must be missing something...
I have 2 tables set up on the same sheet in Numbers 09. I set A1 in Table 2 to equal A1 in Table 1. Now if I add a row above Row A in Table 1, my A1 in Table 2 = Table 1 A2. I've tried playing with the Relative and Absolute selections in the function to no avail. How do I specify that a cel in a table always equals the same cel in another table no matter what is done to the referenced table?
Thanks!

You use INDIRECT.
Table 2 A1 = INDIRECT("Table 1::A1")
or if you want to make it easier to fill in an entire row
A1 =INDIRECT(ADDRESS(ROW(),COLUMN(),,,"Table 1"))
You can take this second formula and fill it across/down. The first formula you would have to edit for each cell.

Hiearchy Node [Alias] - unable to assign in the referencing table!

Hi All,
I really understand the definition and usage of Alias created in the Hierarchy & Taxonomy.
But is there any reason that am unable to assign or use these Alias Nodes in the referencing tables.
for example: Sales representative hierarchy by Region:
USA

Product table am using the above hierarchy and unable to assign/use the Alias node.
thanks

Hi Alexander,
Hope you must have seen the below explanation about Alias
Sometimes, you may want a group of products to appear in more than one location in the hierarchy tree, so that they can be found in various ways using drilldown search. A node alias provides just this ability, and allows products assigned to a single node to appear in two or more locations in the tree. For example, in a repository of gifts, you may have a hierarchy that lists all of the holidays, and you may want u201CChristmasu201D to be found in the tree under the node u201CChristianu201D (if navigating by religion) and the node u201CDecemberu201D (if navigating by month).
Add Internal Leaf cannot be used for Children because you can directly use child nodes in the reference table and for parents you have Add Internal Leaf option if you want to assign parent node to the reference table record.

Referenced Tables

I trying to find referenced tables from schema 'A' to schema 'B'. say for example i have packages in schema 'A" that are referencing the tables in schema 'B'. i wrote the following query it shows one the package name but not the table names those packages refererring. how do i get this?
here is my query:
select *
from user_dependencies d,
user_objects o,
user_tab_privs a
where
d.referenced_owner NOT IN ('A', 'SYS', 'SYSTEM', 'PUBLIC')
and d.referenced_type != 'SYNONYM'
and d.name = o.object_name
and d.referenced_owner = a.OWNER;
help is appreciated...

could you give me an example with all the 3 tables?1. What do you mean by this?
2. When you can get your result from a single table, why you need the other 2?

Could you please explain your requirement a bit more clearly.

Referencing table-aliased column names in JDBC

We are attempting to port an application from MySQL to Oracle 8i, using JDBC as the database connection technology. The app has SQL statements using joins, e.g.
SELECT A.*, B.* FROM table1 A, table2 B WHERE A.field1=B.field2 etc
Often the tables have columns sharing the same name, so the table alias is required to avoid ambiguity (e.g. both tables have column ID, so they must be referenced as A.ID or B.ID).
When using MySQL, the Java code
String strField = rset.getString( "SURNAME" );
or
String strField = rset.getString( "A.SURNAME" );
both succeed if the column name is unique, and if it is not unique, only the second form works. However, with Oracle, the second form never works, even though the column name is a valid column in the table aliased as A. Providing the whole table name does not work either:
String strField = rset.getString( "table1.SURNAME" );
If the Oracle JDBC driver does not support the {table-alias}.{column-name} syntax, then presumably the only way to reference ambiguous columns in joins is to supply the column number instead. (e.g. getString( 14 )). Our application generates dynamic SQL, and having to do this would be a MAJOR problem.
We are currently using Oracle 8i - might this have been fixed in the move to 9i?
Many thanks for any help,

Can't do it by alias, as you would just repeat the
calculation/function/whatever and add whatever additional "stuff"
to create your new column.
ISNULL(row1, 99999) AS ideal,
ISNULL(row1, 99999)+10 AS newideal
etc.
