I have table called INFO and the column called CREATED_DATE . Now the datatype of CREATED_DATE is of varchar2 . Now If I need to query the table through select statement where I need to order the result based on CREATED_DATE , how can i achieve this ?
I have an index on column of table which of data type varchar2. While selecting data from that table I am using following scenarios in where on the indexed column
like '%abc%' like 'abc%' like '&abc'
Will be the corresponding index will be for those cases?
title varchar2(100) y publisher varchar2(20) y categoryname varchar2(20) y rating varchar2(2) y
my query is, select ROWNUM AS "Rank",title,publisher from (select rating,title,publisher from bookshelf_test order by rating desc ) where ROWNUM <=3
returns result ,
1 1 MY LEDGER KOCH PRESS 2 2 TO KILL A MOCKINGBIRD HARPERCOLLINS 3 3 THE MISMEASURE OF MAN W.W. NORTON
But inner query (select rating,title,publisher from bookshelf_test order by rating desc ) returns,
1 5 WONDERFUL LIFE W.W.NORTON 2 5 THE MISMEASURE OF MAN W.W.

why final queries top 3 rows r different than inner query ?
Is there a seeded function by which I can check all the rows which stored dates in varchar column.
I have a table say test (test_data varchar2(100));
Now I will insert all types of records into the table varchar,number dates and then i will write q query to etch all those records only which has dates only
INSERT INTO test(1); INSERT INTO test('ABC'); INSERT INTO test(SYSDATE); INSERT INTO test(TO_CHAR(SYSDATE,'DD-MON-YYYY')); INSERT INTO test(TO_CHAR(SYSDATE,'DD-MON-YYYY HH24:MI:SS')); INSERT INTO test('15/01/2012'); ... commit;
RAW datatype in oracle,any problems we will face using this datatype,Reason is we have column which stores session id in RAW datatype using sys_guid, drawbacks in using this datatype.
We will create a new instance in our production server, but this time, part of it's table structure has a BLOB data type (re: <column name> blob(3000)). It's our first time to handle this kind of Oracle data type. What would be my estimate size for it's default tablespace?
I am exporting using query parameter. I am trying to export subset of table using rowid.
SQL> select rowid , name from tab1;
ROWID NAME ------------------ --------------- AAAM0rAAEAAAAGMAAA sam AAAM0rAAEAAAAGMAAB sona AAAM0rAAEAAAAGMAAC rose AAAM0rAAEAAAAGMAAD chris AAAM0rAAEAAAAGMAAE san .................. .... .................. ....
i am fairly new in the oracle arena, but what would cause a statement such as
ALTER TABLE TEST_TABLE MODIFY text_field1 varchar2(100) DEFAULT 'testval' NULL
to change a column's type from VARCHAR2(100) to VARCHAR2(100 byte)? i found a few mentions of the 100 byte concept online but nothing that jumped out at me.
I ave a few fields in my flat file which might be a CLOB (not sure how the source is storing the data - need to check on that.) I am trying to load this data into my table column which is a varchar2(4000) . I am able to insert most of the data but few records are rejected because of Field too long error....
While debugging the problm I manually copied the field from flatfile and inserted into my table - bingo it worked. (The field was not more than 1000 bytes - only a few lines of information ) My question: When a field is not more than 1000 bytes why couldnt it get inserted as a varchar2?
Note : I cannot make the table column as CLOB because the problem is not with just one column - I have 10 fields which have this problem . So its not advisable to have 10 CLOB fields in the table......
I have specified OPTIONS (BINDSIZE=256000,READSIZE=256000,ROWS=1)
alter table shopowner.jobs add constraint uk_salary unique (min_salary, max_salary); insert into shopowner.jobs values (3, 'dba', 20002,55000, 'jobs');
Why does the above constraint not fail when one of these columns are not unique? It needs to fail both to fail the constraint.
3. what is a transaction? and how do you do it? how does deferred transaction look like?
4. How do you view constraints through isqlplus? 5. How do you drop multiple constraints at once? 6. When would you not use cascading delete? 7. How do you use create like cmd in enterprise Manger? I keep getting this error Failed to
commit: ORA-02264: name already used by an existing constraint even if you delete every constraint or rename ever constraint to anything.
8. how to make comments in isqlplus? 9. how do you add multiple insert values in at once in isqlplus?
I'm looking for a way to select 25% of a view.. I need to do this four time to get all the data. The size of the view changes constantly (I need to split my select because of heavy load on an application)
something like this:
Select * from MyView where [some condition that makes only 0-25% show ]
Select * from MyView where [some condition that makes only 25-50% show ]
Select * from MyView where [some condition that makes only 50-75% show ]
Select * from MyView where [some condition that makes only 75-100% show ]
I tried to search in the forum but found nothing.. maybe ROWID could be used to accomplish this somehow?
I have 3 user defined collection types. I am trying to access the type3's attribute in type1 body (like backward accessing).
Ex. My Collection Types Structure (something like master detail structure)
create type type1 as object ( attr1 varchar2(10), attr2 varchar2(10), member procedure function1
[code]...
so, in the type1 body i have to get or assign the value either to type2's attribute or type3's attribute. I have search all the in internet but i haven't find anything such. how to find the reverse method of accessing the super type's attribute(s) in sub type's body.

I have created the below types and oracle objects.
create or replace type T_EMA_NP_SETDEL_RESP_REC as object ( respCode number, respDesc varchar2(255) )
create or replace type T_EMA_NP_RANGE_LNPTICKET_TAB AS TABLE OF T_EMA_NP_RANGE_LNPTICKET_REC create or replace type T_RANGE_TICKET_TAB AS TABLE OF T_RANGE_TICKET_REC
The following types are created in the Package specification
type t_resp_rec IS RECORD ( resp_code number, resp_desc varchar2(255) ); -- subtype t_ema_lnpticket is T186_IN_REQ_PARAMETER.T186_EMA_LNPTICKET%TYPE; -- Number type t_ema_lnpticket_tab is table of t_ema_lnpticket index by binary_integer;
I have the following two procedures
PROCEDURE getEMAReturnResponse( p_in_call_request_id IN number, p_ema_resp_rec IN t_ema_np_setdel_resp_rec, p_ema_range_lnpticket_tab IN t_ema_np_range_lnpticket_tab, p_endof_event IN varchar)
PROCEDURE Return_Response(p_in_call_request_id IN number, p_ema_resp_rec IN t_ema_resp_rec, p_ema_lnpticket_tab IN t_ema_lnpticket_tab, p_endof_event IN varchar2)
getEMAReturnResponse Procedure:
Accessed by Java application to pass the values. Should call the Return_Response procedure and pass the values received from Java.
Return_Response Procedure
The p_ema_lnpticket_tab is a sort of array that can have multiple values. Please see the example of values. Has all the business rules and validation that should be adhered.
Example of Vaules p_in_call_request_id = 1 p_ema_resp_rec = 12345, 'Operation Failed' p_ema_lnpticket_tab = (1,2,4,5) p_endof_event = Y
i am trying to run a script in which a command tries to create or replace a type.

1. If i'll do drop type FORCE what will happen to the dependent object(might be a table for example) ?
2. I understand that this type is already assigned to some object, but i can't seem to find out which one.
how do i find out which object is depending on the type i want to create or replace?
I have created the below types and oracle objects.
create or replace type T_SETDEL_RESP_REC as object ( respCode number, respDesc varchar2(255) ) -- create or replace type T_EMA_NP_RANGE_LNPTICKET_REC as object ( ticket number ) create or replace type T_RANGE_TICKET_TAB AS TABLE OF T_RANGE_TICKET_REC
The following type is created in the Package specification
type t_resp_rec IS RECORD ( resp_code number, resp_desc varchar2(255) );
I have the following two procedures
Procedure getResponse(p_call_request_id IN number, p_resp_rec IN t_setdel_resp_rec, p_range_ticket_tab IN t_range_icket_tab, p_endof_event IN varchar)
PROCEDURE ProcessResponse(p_call_request_id IN number, p_resp_rec IN t_resp_rec, p_ticket_tab IN t_ticket_tab, p_endof_event IN varchar2)
The get Response procedure is a wrapper procedure exposed to Java to pass values. The Process Response procedure is a main procedure where all logics and business rules are handled.
The Problem is:
How can I pass the values from get Response procedure to Process Response procedure. So that rules and validations are applied. Please note the p_ticket_tab may have many ticket numbers corresponding to p_call_request_id.
I've the following function returning OBJECT type. how to call this function
CREATE OR REPLACE TYPE GET_EMP_OBJ is object ( emp_name varchar2(50) , mgr_id number, dept_id number );
[Code]...
The above function got created successfully. And i'm confused how to call this functions. I tried like below but didn't work
DECLARE t_emp_info_1 GET_EMP_OBJ ; BEGIN t_emp_info_1 := get_emp(7566) ; for i in 1..t_emp_info_1.COUNT LOOP DBMS_OUTPUT.put_line ('Values are'||i.emp_name ) ; END LOOP; END;
I have been creating lot many threads around the same problem, however i thought i knew but realized I do not know or else do not know how to. I have created object type with an attribute READINGVALUE NUMBER(21,6)...How can i use type attribute on this object while declaring variable.....can we use type attribute on NESTED TABLES, similar to the db tables?
example CREATE TYPE READING AS OBJECT(READINGVALUE NUMBER(21,6)); CREATE TABLE INTERVALREADINGS OF TYPE READING;
I am trying to delete duplicates from table without using rowid.
here is data:-
create table test(col1 number(3),col2 varchar2(20)); insert into test values(100,'rocky'); insert into test values(100,'rocky');
[Code]....
I know i am perfoming dml on view. IT wont allow me to perform DML on view which contain columns with expression. IS there any way to delete duplicates without using rowid?
