Beginning with 12c, there is now a way to associate a sequence with a table. It's a new feature called an Identity column.
create table t
(some_id number generated as identity --< creates a system generated sequence
,name varchar2(30)
);
insert into t (name) values ('Smith');
insert into t (name) values ('Jones');
[code]....
I've got plenty of sequences. How can I identify that what are the sequences acting on a table?
View 8 Replies View RelatedIn oracle is it possible to find if a sequence was reset? I know my sequence was reset, looking at the nextval of my sequence, but is there an oracle log or anything which proves that sequence was reset ?
View 2 Replies View RelatedIs it possible to insert new id without sequence id.
For e.g. :
1 , 'BOLT'
2 , 'CHAIN'
i need to insert 3rd and 4th row as
3 , 'screw'
4 , 'driver'
without using sequence (autonumber gen).
I want to create a table, whose first column , patient_id, should be a sequence.

View 1 Replies View RelatedI have a table ABC with two columns NAME and SEQUENCE. The valid values of sequence are from 1..50. The table may not have all the Sequence number. For example following is the data in my table..
Quote:NAME SEQUENCE

Jonh| 5
Amy| 1

I need a SQL to get the data like

Basically I want to have rows for the sequence numbers which are not present i my table. I thought of using the following query to generate a sequence and then join, but does not work.
select rownum from dual connect by rownum <=50
I tried something like
with temp as (select name, sequence from abc where supp_ref_order is not null order by sequence )
select rownum as num, temp.name from dual, temp connect by rownum <=50 where temp.sequence =num
I had created a new table named USERLOG with two fields from a previous VIEW. The table already consist of about 9000 records. The two fields taken from the VIEW, i.e. weblog_views consist of IP (consists of IP address), and WEB_LINK (consists of URL). This is the code I used,
CREATE TABLE USERLOG
AS
SELECT C_IP, WEB_LINK FROM weblog_views;
I want to add another column to this table called the USER_ID, which would consists of a sequence starting with 1 to 9000 records to create a unique id for each existing rows. I'm using Oracle SQL Developer: ODMiner version 3.0.04. I tried using the AUTO-INCREMENT option,
ALTER TABLE USERLOG
ADD USER_ID INT UNSIGNED NOT NULL AUTO_INCREMENT;
But I get an error with this,
Error report:
SQL Error: ORA-01735: invalid ALTER TABLE option
01735. 00000 - "invalid ALTER TABLE option"

How to identify the specific sequence name applied on a table.

I use a sequence to generate an alphanumeric code and I need to update all rows of a table with that sequence. The sequence is created with this code:
SELECT (CHR(TRUNC(s.nextval/1000) + ASCII('A')) || LTRIM(TO_CHAR(MOD(s.currval,1000),'099'))
FROM dual;
I have tried many things - most recently
Update t3_temp_table
SET mergecode =
SELECT (CHR(TRUNC(s.nextval/1000) + ASCII('A')) || LTRIM(TO_CHAR(MOD(s.currval,1000),'099'))
FROM dual;
I get missing expression error.
It works fine if I use a straight s.nextval
I have a table as below:-
CREATE TABLE TEST_EMP_WIP
(
EMP VARCHAR2(20 BYTE),
WIP NUMBER,
MAX_SEQUENCE NUMBER
)
[Code]....
EMP WIP MAX_SEQUENCE RANK
002 2 2 1
003 1 4 2
005 3 5 3
010 1 4
011 1 5
I have to find the next EMP whose MAX_SQUENCE needs to be updated with a sequence. In this case the next would be '010' I fetched the EMP who falls after the max value of the column max_sequence in order of EMPCODE.
select emp_next from (
SELECT emp,max_sequence, LEAD(emp, 1, 0) OVER (ORDER BY emp) AS emp_next
from test_emp_wip where wip > 0 )
where max_sequence=(select max(max_sequence) from test_emp_wip where wip > 0)
EMP_NEXT
010
After sometime, the record would look like :-
EMP WIP MAX_SEQUENCE RANK
002 2 2 1
003 1 4 2
005 3 5 3
010 1 6 4
011 1 7 5
Now the next update should be done to the EMP '002' in cyclic manner.
tell me a way to do this. I can insert new columns if needed in table for calculation.
I found nothing in SQL (all in PL/SQL).I have a table:
create table Parent (pk_id number primary key); --which is filled using sequence seq_Parent.
And I have a child table:
create table Child (rRef number, fk_parent number primary key (rRef, fk_parent);
that I need to insert into Child using seq_parent but I want to insert the same sequence for each group of rRef. I dont know how to do that using SQL not PL/SQL.
I have a stored proc SP_INSERT_TRAINEES.Here sTraineeNo is provided as input which has count of trainee needs to be inserted in table aaa_foc.user_profile. The sequence is used to generate ids as :

I want the values for ids to be inserted as 001,002,003,.......010,011,................099,100,101,............999.So that the values in the table would be like TRAINEE001,002.......
I have tried to use LPAD to it but the values are getting insertes as TRAINEE1,2,3...........

CREATE OR REPLACE PROCEDURE AAA_FOC9.SP_INSERT_TRAINEES
