SQL & PL/SQL :: Oracle Primary Key Error On Sequence Number Generator
Mar 11, 2011
I have a table called table 1 and I am trying to insert a few values in this table and i am constantly getting bogged down by a primary key error. Strange thing is this primary key called "ID" on the table is a system generated sequence value number. The error is
why the error is coming up and any way to resolve it. I checked the max sequence number value and kept running it for a while and then tried to run my insert statement but no luck yet.
Is there a function or a process to generate and maintain an alphanumeric sequence?
I need to be able to sequentially generate both a 3 and 5 byte case sensitive alphanumeric primary key that uses A-Za-z0-9 characters intermittently of which the 5 byte MAY be a subset of the 3 byte. e.g. the key can be 00000 or a3BD7.
so I need to be able to generate a new 5 char using 3 char base and if that value is not available, generate a unique 5 char value and allocate the substr(1,3) of that value backwards.
Ex1: unique customer location comes in - not a preexisting customer name (same name,different location address doesn't exist) --> select nextval.[5char] into v_long_c to insert into customer_loc table, and substr (v_long_c, 1, 3) for customer name table.
EX 2: unique customer location comes in. customer name exists in customer table with 3char val A39, but that location doesn't exist in customer_location table (5chars are location specific).
I need to take the A39 and generate new 5char for that unique location using that prefix (A39) if possible.
However, a number of a39-- already exist, though not all assigned to the same customer name (we're trying to keep them grouped together but that might not be logically feasible)
How do I select next a39||[2char] for that unique location - and if that value is not available (all 62*62 possibilities have been used for A39--), select nextval.[5charseq] into long_key.
I suspect someone out there knows the functions I can use to create this or has written a package to do just this; I suspect with enough time I could do it, but I don't currently have the time or knowledge to develop it within these deadlines. I thought it would be easier.
My short-sighted solution was to create a static table of all iterations of A-z0-9 5 char values, select one, mark it used and move on. Unfortunately 62^5 is a substantial number (913+million records) and that table took a LOT of space, causing my development server to groan and crack miserably. indexing on it takes a lot of space too (and trying to build multiple indexes exceeded database size). But without an index on the 3char field, selecting an available 5 code from it based on the customer_3char prefix took five minutes - much longer than the fraction of a second I need.
I'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.
I'm trying to create a sequence for a primary key to simply auto-increment by the default of 1. I have a sql script written to generate mt tables, and I'm not sure how to modify the script to include the sequence. I also just want the sequence for a specific column, ie, PK, not the PK in all tables.
Here's a snippet from my script:
create table image ( image_id int NOT NULL, source_id int NOT NULL, CONSTRAINT image_id_pk PRIMARY KEY (image_id), CONSTRAINT fk_source_id FOREIGN KEY (source_id) REFERENCES source(source_id) );
Would I add the create sequence statement right after the create table, and if so, how do I apply the sequence to only 1 table and a single column?
I have the following select query that works perfectly fine. Returns 25 rows based on the descending order of the price.But, I want add one more expression to this list of columns in this query (apart from customer_id).
the expression should look like Cust-01 for the first customer from the below query all the way to Cust-25 for the last customer.But how can I can generate 01 to 25 in oracle?
select customer_id from (select customer_id from capitalPLAN where member_status = 'MEMBER' AND customer_id NOT in ('156','201','1385','2125','3906','165') order by price desc ) where rownum <= 25
I have set up a schema using a DDL script in Oracle 10g. I am linking this through to a Visual Basic 2008 fron end. The connection is fine. My database of is for a car hire company project.
I need to know how to create an auto increment for a primary key field, like Access does.
For example here is my table structure for my Rental_Payment table.
-- TABLE RENTAL_PAYMENT CREATE TABLE RENTAL_PAYMENT ( PAYMENTNO NUMBER NOT NULL, CARDNO NUMBER NOT NULL,
In our production, we have two nodes in the cluster. We use the sequence for one of the main table for primary key. Our application is expecting sequence number increments along with created date time stamp. Right now sequences are cached for each node and it creates problem for the application. We would not like to use NOCACHE option because it causes performance issue.
This is the current scenario -
Transaction #1 on Node 1 - Seq ID 1 - Time Stamp 12:01 Transaction #2 on Node 2 - Seq ID 51 - Time Stamp 12:02 Transaction #3 on Node 1 - Seq ID 2 - Time Stamp 12:03
When I try to query based on the time stamp, primary should also go up. To be very clear on what I would like to have, please consider the following example.Without using NOCACHE option, I need to have the data in the following order.
Transaction #1 on Node 1 - Seq ID 1 - Time Stamp 12:01 Transaction #2 on Node 2 - Seq ID 2 - Time Stamp 12:02 Transaction #3 on Node 1 - Seq ID 3 - Time Stamp 12:03
In other words, sequence number should always increment along with the time.
I have a following select statement where I am not generating a sequence in any of these WHERE clause, GROUP BY or ORDER BY clause, DISTINCT clause, along with a UNION or INTERSECT or MINUS or sub-query.
I have query like this
"SELECT AER_ID_TEMP.AER_ID, AER_ID_TEMP.D__PRNO, AER_ID_TEMP.D__PCNT, CAST((select char_value from aris_param_data where param_id = 101)||seq_record_id.nextval AS INT) as RECORD_ID FROM AER_ID_TEMP"
but still encountering a error "ORA-02287 sequence number not allowed"
CREATE OR REPLACE TRIGGER audit_emp AFTER INSERT OR UPDATE OR DELETE ON Employee FOR EACH ROW declare my emp_audit%ROWTYPE; begin if inserting then my.action := 'I'; [code].......
It works alright but i need to enter a sequenced value to a column audit_id which is a column in the emp_audit table when a change takes place, but when i define the variable it gives be an error as bad bind variable so where can i define this column in this trigger so get a sequenced value every time i d or u occurs .
Is there any way to get the last Sequence Number generated regardless the Sequence name? Something like dbinfo('sqlca.sqlerrd1') within Informix?
Imagine I have 2 sequences. Imagine that I run both several times until 20:00 hours. Imagine that at 21:00 hours I would like to know what was the last generated number created by any of the sequences. I don't wann know wich sequence generated the last NEXTVAL, I only want to know the value of the last NEXTVAL used.
Is it possible without mentionating the Sequence name?
I am facing issue with my sequence number about sequence number generated..I want it to follow the sequence all the time, i.e. it should take next incremental number to last generated seauence, but it generates random one all the time, i.e
I have a result set with three columns as 'Product Category', 'Product' & 'QtySales' and 10 rows, sorted in the order Product Category, Product. This means, a product category will have one or more products under it.
Now i want to add a fourth column to my result set, which should display a incremental number sequence from starting from 1, 2, 3.. for each row. Also when the value of the Product Category (1st column) changes, this sequence should be restarted again from 1.
I 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..
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 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 sequence seq minvalue 1 maxvalue 99999 start with 1 increment by 1; create table t ( id number, b date); insert into t values (seq.nextval,sysdate); update t set b=sysdate-1 where id=seq.currval; update t set b=sysdate-1 where id=seq.currval * ERROR at line 1: ORA-02287: sequence number not allowed here
Name _____ Smith Street Smith Street John Street Ed Street Ed Street Ed Street
and need to assign sequence numbers only when the record (Name) changes, e.g. :
Name Seq _____ ____ Smith Street 1 Smith Street 1 John Street 2 Ed Street 3 Ed Street 3 Ed Street 3
I have experimented with row_number partition but then i just get the sequence returning to 1 when the name value changes.
If I grouped the records by Name I would like to have unique, sequential numbers: 1, 2, 3 but where there is the same name I would like the sequence to stop and the number to replicate?
i want to get serial numbers in oracle forms. i have one data block with 10 rows and a non database display item with corresponding length as that of the original data block .
when ever i am executing the form i want to see the serial number generated in the display item and when i inserted a new item or row it should show the corresponding rownum.
eg:
empno name serialno 5 tom 1 4 tinil 2 6 sofy 3 7 john 4 1 albert 5 2 michel 6
I have a CSV file with 100 records and one of the column as FILE_ID. I want to load one unique number for all 100 recs not for every records.
suppose my sequence returns 3 as next val i want to load 3 for all 100 records. How to implement this in control file or sh file . I am using shell script to call sqlldr.
My problem, I have the query which works correctly. However as you can see there is always a sequence number in the end of variables and I am not sure the total number of cases, so I have to create a loop for the same query.
I am doing the same things on BREINV1 BREINV2 BREINV3 BREINV4... AND BRENUMINV1 BRENUMINV2... so the sequence should add a number in the end of variables...
I am switching database from access to oracle 11g. I have create all the required tables, but I am stuck at one point. The previous person who created access database had auto increment with SG0101, SG0102,........ In oracle I know we can auto increment primary keys but only with the numbers not with characters.
So I have customerid which is a primary key and it automatically increments the number, but I have one more column with memberid where I am inserting all the ids that start with SG0101 bla bla.....
I already have 800 member ID's that start with SG, but that value doesnt automatically increment because I dont have any sequence or trigger to do that.
So how do I create a sequence and trigger that will automatically start value with SG and keeps auto incrementing?
