XML DB :: Possible To Remove XMLSchema Restriction From XMLType Column?
Oct 24, 2012
I have an XMLType column that is validated via some XMLSchema. Now I want to remove this restriction and make it just a generic XMLType column. I tried bunch of alter table commands but I couldn't figure out the magic combination. Is this possible?
Here is the actual problem. Unfortunately, we ended up both local and global schemas using the same URL. We have customers out there with both schemas (early customers) or only global schema (new customers). Most of the tables were created before the global schema was added. So, they are referencing the local schema. Now we want to evolve our schema, and I am trying to write a sql script to clean-up this mess. if only global schema exists then (these are late customers)
- do nothingelse if both global and local schema exist then (these are early customers)
- If any table or table.column has dependency on local schema (I can find this out from user_dependencies) I am going to mark those tables/columns as no schema validated. i.e. remove all references to local schema
- delete and purge the local schema
- modify those tables/columns and make them point to the global schema end if
- evolve the schema (only global one is left)
Is there a way to modify a column definition and move its reference from local schema to global schema where both schemas have the same URL? Of course the main constraint is that we do not want to loose customer data. By the way, both local and global schemas are identical in terms of xsd.
is it possible to change XMLSchema/Element settings of an XMLType column from X to Y, X to null, or null to X?
Tell me restriction on commit means where this keyword is not used....like i somewhere read in trigger we can't used commit...instead of that we use pragma autonomous_transaction..
but my confusion arise when i see commit used in trigger in our database table....
is commit used in trigger , if not then what will be use...
Another one is commit used while creating procedure or function?
I would like to pass my 1Z0-047 certification, but I don't understand the limitation on the scalar subqueries, especially for the having clause.
Here is my scalar subquery because it returns only one value.
CODEselect avg(list_price) from product_information
I use it in a having clause as a scalar subquery and it works
CODEselect status ,avg(list_price) from product_information group by status having (select avg(list_price) from product_information) >= avg(list_price);
but it is documented that it can't works :
QUOTE There are also important restrictions on scalar subqueries. Scalar subqueries can�t be used for: Default values for columns RETURNING clauses Hash expressions for clusters Functional index expressions CHECK constraints on columns WHEN condition of triggers GROUP BY and HAVING clauses START WITH and CONNECT BY clauses
Is there any way to apply the restriction on analytical functions, just like WHERE and HAVING .AS we know that we can apply the restriction on table by using WHERE and grouping functions by using HAVING clause .
For Ex: Departments wise count including all employees record :
SQL> select count(*) over(partition by deptno) dept_Count, ce.* 2 from scott.emp ce 3 order by deptno, job;
DEPT_COUNT EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO ---------- ----- ---------- --------- ----- ----------- --------- --------- ------ 3 7934 MILLER CLERK 7782 1/23/1982 1300.00 10 3 7782 CLARK MANAGER 7839 6/9/1981 2450.00 10 3 7839 KING PRESIDENT 11/17/1981 5000.00 10 5 7788 SCOTT ANALYST 7566 4/19/1987 3000.00 20 [code]....
I want my user to be restricted for entering duplicate time within two times.
create table asd(dt_frm date,dt_to date);
insert into asd VALUES(to_date('01-04-2012 08:00','dd-mm-yyyy hh24:mi'),to_date('01-04-2012 10:00','dd-mm-yyyy hh24:mi')); insert into asd VALUES(to_date('01-04-2012 09:00','dd-mm-yyyy hh24:mi'),to_date('01-04-2012 11:00','dd-mm-yyyy hh24:mi'));
now in the second insertion I want to alert the entry user that 9am already falls in the saved record which is 8am to 10am and so that this record can't be saved.
I have one question regarding database access. I have one database server on which 3 databases are running. I want to restrict each database access for particular group only , so if anyone outside of this group try to access the database then they can not access the database.
Question is end user never login to Database server and access the database , they always connect to the database using different tool like Pl/sql dev,sqldev etc.
Is there any option through which I can make database access within group only ?
Currently, I am using oracle 10g and getting foolowing error
"PLS-00436: implementation restriction: cannot reference fields of BULK In-BIND table of records"
When trying to access attribute in record-collection inside FORALL. I know its prohibited in 10g but allowed in 11g. My questions is how can we achieve this in 10g. I will rephrase my problem:
I have three record-collections say rc1, rc2 and rc3 and I need to put all these record-collection inside final record collection say FC using FORALL
In my organization, I have a table and in that there is a column named "code".I want to restrict some insertion to that particular column. suppose that code column values are 12 and 1245 then i cant insert the value 12,1245, 1 ,124 and so on but i can insert 2 ,123,15,12456 and so on.
that means the new values should not be any substring of the existing data from left. making that column primary key and then I had a logic to compare the existing value which are longer than the new value and then to perform this.But dont know how to make it happen correctly.
i want to create a function that build a return xml (XmlType):
create or replace function plainLanguageSummary(nip varchar2,id number,code_language varchar2) return XmlType as

I have issue while loading xml_data into xmltype field in the table.Issue is whenever there is a special character like this 'revisions to §6' in xml text then it is 'revisions to §6' when its in the xmltype field of the table.
There is this new character appended before every special character.I have checked the database characterset.Characterset: NLS_ CHARACTERSETValue: AL32UTF8

I have loaded into an Oracle table defined as XMLTYPE. I'm okay with PL-SQL and stored procedures, where I will ultimately do this processing once I get a handle on XML DB querying from an XMLTYPE table.
Based on reading the oracle documentation about XML DB, and more importantly, reading dozens of posts to this forum,I have been successful in loading the XML files into a SQL XMLTYPE table and doing simple queries against that table to retrieve some of its data so that I can then insert that data into other target oracle relational tables.
how to select parent/child data from XMLTYPE tables. I am able to follow the forum examples and can replicate the methods shown on the many example XML contents shown on this forum, but not against the XML that I have to process. I am wondering if my struggle is caused by my lack of knowledge, or by ill-formed XML content supplied to me by the educational vendor.The XML content has structured the XML content nodes in such a way that I do not seem to be able to apply the parent/child sql methods.I have been able to use for other XML examples I have tested against.
My XML file shown below represents High School Transcript data, for which I need to be able to parse out into my own oracle relational tables for that student, his personal info, and his course info, etc. i.e., for our example, which courses he has taken for which High School grade levels. The vendor-supplied XML seems to put the Courses and the High School grade level in "parallel nodes," instead of parent/child nodes, so I am struggling to be able to use SQL to differentiate which course the student took in NinthGrade versus TenthGrade.
-- WHat I would like to determine from a select statement:
LASTNAME GradeLevel COURSETITLE ============================= Smith NinthGrade PHYS ED 101 Smith TenthGrade CALCULUS 201 Smith TenthGrade ZOOLOGY 202
(The data has been simpliied and masked, but is true to the content and is queryable).

i am populating 3 records in my data block.i do not want more than 3 rows.but when i click the plus icon in form menu one more row is getting generated which i do not want. i can restrict the new record addition through plus icon in menu bar for a particular block.
,in 11g,is there a way I could limit the number of open application actions by some os user ?We have an application where users are executing the same thing while the last is not yet finished,so we have several same things runninng at the same time executed by the same user.
Can we restrict that somehow through the database or that needs to be done through application?
I receive source data with leading zeros. The Rules says: "If there is a leading 0 it has to be removed and data has to be shown starting with character 2".Here is my code I started with:
I have a file name field in my database that stores each file name with the extension .TXT and almost each file name is different.I would like to remove this extension from all of the file names without using the different file name each time I update. Is there any SQL statement that will allow me to do this? I am using Oracle.
