Sequence nextval is a pseodocolumn, but where the value of nextval is stored and why before we use CURRVAL for a sequence in our session, we must first initialize the sequence with NEXTVAL?
View 5 RepliesI'm using Oracle 11g and I'm trying to set the sequence nextval as default to Primary Key row, when I create the table, Oracle throws an exception that columns are not allowed. Here is an example.
CREATE TABLE EMP (
EMP_ID VARCHAR2(50) PRIMARY KEY DEFAULT MYSECUENCE.NEXTVAL)
I am trying to understand the difference between using sequence.NEXTVAL from DUAL as against using it direclty in an INSERT statment.
--Sequence Creation
CREATE SEQUENCE SEQ_ID START WITH 1 MINVALUE 1 NOCYCLE CACHE 500 NOORDER;
--Table1 Creation
Create table TABLEA (COL1 number, COL2 varchar2(10),
constraint COL1_PL primary key (COL1));
--Table2 Creation
Create table TABLEB(COL3 number);
alter table TABLEB add constraint COL1_FK foreign key(COL3) references TABLEA(COL1);
-- Option1 - Using sequence.NEXTVAL from DUAL
DECLARE
v_seq_num NUMBER;
BEGIN
SELECT SEQ_ID.NEXTVAL INTO v_seq_num FROM DUAL;
INSERT INTO TABLEA (COL1, COL2) VALUES (v_seq_num, 'test');
INSERT INTO TABLEB (COL3) VALUES (v_seq_num);
END;
-- Option2 - Using sequence.NEXTVAL in INSERT USING RETURNING INTO clause
DECLARE
v_seq_num NUMBER;
BEGIN
INSERT INTO TABLEA (COL1, COL2) VALUES (SEQ_ID.NEXTVAL, 'test') RETURNING COL1 INTO v_seq_num;
INSERT INTO TABLEB (COL3) VALUES (v_seq_num);
END;

I used the following code to create a sequence
create sequence mg_sites_seq
start with 1
increment by 1
maxvalue 10000
cycle
cache 5;
then in my values clause of an insert without a distinct I had mg_sites_seq.nextval as one of my values but I'm getting an error that says it's not allowed there.I also tried to use it as a default value on the create table description (my preference) and got the same message. When I did the create table I commented out the field in the insert and value clause.
I’m trying to avoid a cursor solution and I can’t accomplish this using any group by or aggregate/analytical functions. This approach is basically trying to apply a group by while forcing the group by to operate on the data in a specific order(not the group by order). why is currval giving me the nextval we should get somewhere?
Query:
INSERT INTO WAREHOUSE_DEV.STG_COV_SUBPROGRAM_FUN_CS1 (
CASENUMBER, PREV_CASENUMBER, CLIENT_NUMBER,
PREV_CLIENT_NUMBER, PROGRAMNAME, PREV_PROGRAMNAME,
SUBPROGRAMNAME, PREV_SUBPROGRAMNAME, COVERAGE_YEARMONTH,
CLIENT_COVERAGE, PREV_CLIENT_COVERAGE, CS_COUNT)
select CASENUMBER, PREV_CASENUMBER, CLIENT_NUMBER,
[code]...
The key is that when you have cs_count of 1… get nexval, when you have value of -1 get currval, zero is zero… The first row would get nexval…. So 1 the next seven rows should be 1, then next row 0, the next row 2 and the last 5 rows will also be 2.
Query with currval and nextval:

My organisation is currently discussing different storage options for the database storage. Our production database is nearly 2TB and we do not want to continue with the existing NetApp storage (we use a 2 node RAC running 11.2.02 with nfs filesystem from NetApp filer).
We were looking at different options and came across Nimble Storage, they are very fast growing company aiming mid-range storage customers. The initial talks and demonstration looked very promising in terms of IO performance (they claim 40,000 - 60,000 IOPs for their CS400 series Nimble Storage array) and other options they are providing but we understand that majority of their customers are using it for VDI and other infrastructures.
They have demonstrated us using if for Oracle database with ASM storage over iSCSI LUNs. We are yet to do the POCs and benchmarking.
Has anyone come across Nimble Storage for running Oracle databases?

View 1 Replies View RelatedI have been implementing a script to change a lot of data in a database production.Because of this the database will be 100% dedicated to the execution of that script, in the sense that nothing else will be running in this period (the application will be stopped).
what can i do to improve performance of that execution? is there any oracle manual online for this type of problem? I do not know if it's possible, but I'm thinking of things like disabling locking mechanism (if possible I could run instead of a process many processes in parallel), disabling index growing (during the process), disabling constraints.
the view from where we can fetch information for a foreign key viz. reference table, referenced columns etc.
View 3 Replies View Relatedi enabled auditing by setting
audit_trail=db,extended in spfile,and restart the database and after that i issued command to audit as below :
audit select on emp by access;
but how to see audit log information(ie from which table),i checked dba_audit_trail but it doesnot have any record.
I am developing some automated test packages for my PL/SQL Packaged code. Going forward I can code the test package in conjunction with the code but I have some historic packages that I would like to develop these test packages for.
To save time I would like to employ oracle data dictionary views in order to construct the framework for my test package. This includes using SQL to get a list of procedures / functions within the package in order to create the test procedures (spec and body). I can do this in a basic way using the user_procedure view with something like...
SELECT 'PROCEDURE test_' || LOWER(procedure_name)
|| ' (p_result OUT VARCHAR2 IS BEGIN JTA.ACCOUNT_PROFILE_MAINT.' || procedure_name || ' END '
|| LOWER(procedure_name) || ';'
FROM user_procedures WHERE object_name = 'ACCOUNT_PROFILE_MAINT' AND subprogram_id != 0 ORDER BY subprogram_id;
However, the above only really works (in simplistic form.. without parameters) for procedures within the package. I would also like to be able to determine if the procedure listed is actually a function or procedure (so that I can alter the syntax accordingly to generate a correctly formatted string calling the program unit).
So, initially how do I determine the type of package program unit I have (Proc/Function)? Do I need to go to all_source to get this information or are there other views available I can join to?
Eventually I would like to extend this to be able to automatically include any parameters in the generated calling string.. again, is there any other option apart from all_source to get this information?

We are running Oracle 10g. I need to pull the DDL information from our Oracle tables. The following SQL statement returns the result as a "HUGECLOB". Is there a way to convert the result to text in varchar2 data type? Since tables being processed have numerous partitions, the DDL information for them is quite large, therefore, using substring would not be a viable alternative.

Redo log information can be transmitted in one of two ways from the primary database to the standby database: either by ARCH or LGWR.

Is there any way to capture the version wise objects (Packages) information from the oracle data base.
Ex : I have package P1 which was created on 01-NOV-2012 with version 1 . After 10 days same package has been updated version 2 with some enhancements.Like that the package will be updated according to the latest requirement.
