i had a requirement to generate unique numbers without sequences.
For Example: i had a table called "Test".Test has two columns.
ID and Name are 2 column names.Primary key constraint exists on column(ID).
How to generate the ID values without using sequence and Stored procedures.
I have made one application form where users need to enter some data. This data is getting inserted in four tables. As in for now the data is properly getting saved and retrieved only for one user at a time. But problem arrives when more than one users are simultaneously making an entry and saving the data at one time.Same number is getting generated for the users who are saving the data at one time which should not happen.

I have two control block i.e. class_register and student_info. In which student_info is multi-record block which contains stud_id, stud_name, stud_roll_no. Based on the class_register block, stud_id and stud_name is generated in the student_info table. Now I want to generate stud_roll_no automatically until the last record is present.
View 4 Replies View RelatedI need a "solution", guidance to a problem I have to solve. I have different letters with a value associate to it like
A:10, B:20, ..., G:250 and I have a Target to reach TARGET= 90
and I need to find among all letters I have which combination is equal or closest to my target.
A:10
B:20
C:20
D:20
E:30
F:40
G:250
IF there is more than one solution possible, the first found is perfect. With my example I can reach 90 with different combinations:
A+B+C+F
A+B+D+F
A+C+D+F
B+C+D+E
B+E+F
C+E+F
D+E+F
To complicate the things I have up to 10 different letters that need to combine to match my target. If there is no combination that exactly match my target, the closest higher combination is picked.
Is there a way to generate a unique identifier(length 8), which can contain numbers (0-9) and letters(a-z) in pl/sql or sql ?
Note :- in oracle 9i.
I don't want to generate row_number for unique values 'C' and 'E' in below query.
SELECT NAME, ROW_NUMBER() OVER (PARTITION BY NAME ORDER BY NAME) FROM
(SELECT 'A' NAME FROM DUAL
UNION ALL
SELECT 'A' FROM DUAL
UNION ALL
SELECT 'A' FROM DUAL
[code].....
Means row_number should be NULL for unique values.
I need generate an unique number without sequence. I am using Oracle 11.2, here is the details. The column idSeq is unique withing one specific idType. I don't want a sequence for each idType.
create table tb_test (idSeq number(5), idType number(5), addr varchar2(256));
insert into tb_test
(select case when idSeq is null then 1 else max(idSeq)+1 end, 3, 'Main street');
I am having ORA-00937 : not a single-group group function error
I need to generate random and unique 6 digit number in Oracle. I need to insert these numbers into a table. I tried using DBMS_RANDOM package, which generates random 6 digit numbers, but fails to generate UNIQUE numbers.

I have something upcoming task which include a merger of two database instances. The schema structure is exactly same and there is no duplicity problem. I want to dump the both schema data in one instance. The only challenge i have here is "How to manage the sequences?".
Explanation: Instance A.
Sequence : 1,2,3,4,....20
Instance B
Sequence: 1,2,3,4....20
Requirement : when i merge it should be
Instance C: 1,2,3,4...20 [from Instance A ] cont.. 21,22,23,24.....40 [From Instance B]
We have a requirement to install a new application into a 2 node RAC database.
Going over the installation scripts, I noticed that there is a requirement to use sequences, which immediately set the alarms ringing - I know that using sequences with RAC may cause issues (esp as the script is set to cache 500 values at a time).
The way we are planning to implement this application is by channeling the application through a service that is preferred on one node. The second node will be set to available for the service. The database will ONLY be used for this application.
Will this be enough to get round this situation? Or will the second node still try and cache sequence numbers?
I have created a Sequence called testseq. Its working fine since last 1 week. Suddenly no one sequences will not create nextvalue. after executing nextval its return null row.
View 2 Replies View RelatedI am having a table with out a primary key .It also contains data.
My requirement is to add a new column to the table and update the column value with unique and sequential number , starting from 1 to end of rows.
This has to be done without using a sequence.
I have a temp table and want to insert that data into 2 tables. In both of my tables i have a sequence column but in my second table its a foreign key to the main table
up_query="INSERT INTO AFFILIATE (FNAME,LNAME,EMAIL,PHONE,ORG,ADDRESS1,ADDRESS2,COUNTY_ID,AFF_ID)
Select a.FNAME, a.LNAME,a.EMAIL,a.PHONE, a.ORG, a.ADDRESS1, a.ADDRESS2,C.COUNTY_ID,'AF'||aff_seq.nextval
FROM temp_aff A LEFT OUTER JOIN COUNTY C
ON UPPER(A.COUNTY)=C.CNAME";
$up_query2= "INSERT INTO TEST4 (DEPT_ID,CAMP_ID,AFF_ID, PASSWD)
SELECT D.DEPT_ID,C.CAMP_ID,aff_seq.currval,'Zq'||dbms_random.string('A',4)||'$8' from dual,TEMP_AFF A
left outer join DEPT D ON (UPPER(A.DEPT)=UPPER(D.DNAME))
left outer join CAMPUS C ON (UPPER(A.CAMPUS)=UPPER(C.CPNAME))";
However in my test4 table its inserting the aff_seq.currval for all records. Its not incrementing as in the affiliate table.
Using Oracle 11g, below is the table, partitions, unique and non-unique local index:
CREATE TABLE DOCA( DOCA_ID NUMBER NOT NULL , DOCA_BKG_PAX_ID NUMBER NULL , ROW_PURGE_DATE DATE NULL ,)PARTITION BY RANGE(ROW_PURGE_DATE)INTERVAL(NUMTOYMINTERVAL(1, 'MONTH'))( PARTITION P2007 VALUES LESS THAN (TO_DATE('01/01/2008', 'dd/mm/yyyy')), PARTITION P200801 VALUES LESS THAN (TO_DATE('01/02/2008', 'dd/mm/yyyy')),) TABLESPACE T0; ALTER TABLE DOCA ENABLE ROW MOVEMENT;
CREATE UNIQUE INDEX XPKDOCA ON DOCA( DOCA_ID ASC, ROW_PURGE_DATE ASC)LOCALREVERSE TABLESPACE I0; ALTER TABLE DOCA ADD CONSTRAINT XPKDOCA PRIMARY KEY (DOCA_ID); CREATE INDEX XFKDOCA_DOCA_BKG_PAX_ID ON DOCA( DOCA_BKG_PAX_ID ASC)LOCALREVERSETABLESPACE I0;
I would like to know the difference between the performance of the unique and non-unique local indexes?.
I have the following set of numbers that i am passing in as one input into a stored procedure.
234,456,234,456,567
Now i want to take this list of numbers and use it in an IN statement:
select * from table where column_a in (P_INPUT);
however, when i try this, it give me an invalid error. I have tried inserting single quote around each value and get the same invalid error. I tried a To_char around my column, which solved the error, but it never finds a match!
I want to get 10 random numbers from existing 100 numbers. How can we get/generate random numbers ?
for example I have a table with customer ID, customer Name, having 100 record. We want 10 customers ID randomly from that 100 record not repeated any number. Have any command or procedure for that ?
I have a column of datatype varchar2
this column may contain char or may contain number or may contain both
some values in this column are only number is there any function or any other way to get those column that are only number
Earlier, we had a discussion how to generate the permutations. generating the code for combinations
For eg: if I have input as [1,2,3,4,5] then 5c2 = 20 combinations should be generated as pairs
1,2
1,3
1,4
1,5
2,3
2,4
2,5
3,4
3,5
4,5
Total of 10 combinations

Here i face probelm that he numbers must be follw by DOT "." , this is not correct if the statment only conatines numbers without DOT that not extract. As the
SELECT REGEXP_SUBSTR ( 'hello to 8898989898989 jkjk nnnm mnj'
, '([0-9]+.[0-9]*)' || -- Starts with digit(s) (may or may not have digits after .)
'|' || -- or
'(.[0-9]+)' -- starts with decimal point
) AS result
FROM dual
;
but mean i have to add . after numbers . as follow
SELECT REGEXP_SUBSTR ( 'hello to 8898989898989 jkjk nnnm mnj'
, '([0-9]+.[0-9]*)' || -- Starts with digit(s) (may or may not have digits after .)
'|' || -- or
'(.[0-9]+)' -- starts with decimal point
) AS result
FROM dual
;
but this is not right
i want to extract numbers without DOT also.

I need to create a stored function that could find/return missing numbers between number_from and number_to for each record in table t.
For example:
