CREATE TABLE test
(id NUMBER PRIMARY KEY,
name VARCHAR2(30));
Step2
CREATE SEQUENCE test_sequence
START WITH 1
INCREMENT BY 1;
Method1 Follow Step1 and Step2 and create a Trigger as below :
CREATE OR REPLACE TRIGGER test_trigger
BEFORE INSERT
ON test
REFERENCING NEW AS NEW
FOR EACH ROW
BEGIN
SELECT test_sequence.nextval INTO :NEW.ID FROM dual;
END;
/
Method 2 Follow Step1 and Step2 and directly have an insert statement as below:
INSERT INTO test (id, name) VALUES (test_sequence.nextval , 'Jon343');
Method 1, the Trigger is not getting created, however by following Method 2, I am able to generate auto-increment number.
which method is more efficient in terms of performance to generate an auto increment number in oracle.
Step1
CREATE TABLE test
(id NUMBER PRIMARY KEY,
name VARCHAR2(30));
Step2
CREATE SEQUENCE test_sequence
START WITH 1
INCREMENT BY 1;

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?
I have already done auto increment by making sequence and trigger. but now the problem is when i am trying to retrieve data from that table it returns all data perfectly but the primary key that is my auto increment value shows blank.I am facing this problem with join query, there 4 table left joined in my query. But when I remove join from my query then it shows that value.
But i need that value in my join query.So, what is the problem and what can I do?And other thing is when I apply this query in Oracle SQL Developer, it works perfect.
My Query:
return $this->db->query("select * from TBL_EMPLOYEE_BASIC left join TBL_EMPLOYEE_DETAILS on TBL_EMPLOYEE_BASIC.EMPL_ID = TBL_EMPLOYEE_DETAILS.EMPL_ID left join TBL_EMPLOYEE_EDUCATION on TBL_EMPLOYEE_BASIC.EMPL_ID = TBL_EMPLOYEE_EDUCATION.EMPL_ID left join TBL_EMPLOYEE_EXPERIENCE on TBL_EMPLOYEE_BASIC.EMPL_ID = TBL_EMPLOYEE_EXPERIENCE.EMPL_ID where

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 want to export the oracle data into an excel sheet. I have written the code by using UTL_FILE package. but i am getting the output as shown in the screen shot(without formatting the column size as the width of the data it has). But I want the output column width to be set according to the size of the data automatically.

/*Creates the log needed to increment ID*/
create sequence seq_log;
CREATE TABLE MESSAGE_LOG_TABLE

IDNUMBER(10)NOT NULLPRIMARY KEY,
[code]...
When I run the above my create sequence completes successfully but I get a ORA-00955: name is already used by an existing object error message on the create table. I have dropped all tables and sequences before running my command but I still get the same error message.
After it bombs out it appears that SQL+ want's more information for it begins to give me line numbers as if it is looking for a ";" to end the above command. I have to exit SQL+ and log back in to continue working.

I have three tables.
One for projects, one for volunteers, and a bridge entity for the many to many relationship between the Project and Volunteer.
In Project table, I have a field called, Volunteers_currently_signed_up, which means the number of volunteers currently signed up to participate in a project.
When I add an entry to my bridge entity which is composed of Volunteer_ID and Project_ID, I want the Volunteers_currently_signed_up to increment by 1, where the Project_ID in the bridge entity corresponds to that in Project.
I have very very little PL/SQL, and this is my amateur attempt so far:
CREATE OR REPLACE trigger "BI_Volunteers_currently_signed_up"
BEFORE INSERT OR UPDATE ON Volunteers_in_project
for each row
WHERE Volunteers_in_project.Project_ID=Project.Project_ID;
begin
Project.Volunteers_currently_signed_up += 1;
end;

I want to increment a counter in a loop based on a condition.
Here is how my xml looks like
<result>
<resultset id=1>
<value>
[Code]....
I need to look at each and every resultset and check if the value is >400 and if it is then display some text. Something like this
<outputvalue>
Yes, there is a value greater than 400
</outputvalue>
In my XSL, I declared a variable called count with value 0. I created a for-loop which goes through these results. Then inside the loop there is a condition to cehck if the value is > 400. If the value is >400, then the counter is incremented.
````````````````````
<outputvalue>
<xsl:variable name="Count" select="0"></xsl:variable>
<xsl:for-each select="/results/resultset">
[Code]....
There is a problem with the above code is that result is like this
<outputvalue>
*1*
Yes there is a resultset with greater than 400
</outputvalue>
Is there a way I can just remove the character 1 from the output? Or is there a better way to increment?

How to check for the increment of a space of the tablespace based on the particular table. (i.e.) Say a scenario, if am trying to load the data for a particular table, for first I loaded some 10000 records and then again loading 50000 records ,so based on the icrement of the reocrds the tablespace size also increases gradually . so for this scenario how to monitor the increment of the space.
View 13 Replies View RelatedIs there any strcuture or fucntion that can make the table have something like rotation.
I mean the record can be first in first delete.
So,for example , even the table have limit row for example , 100 row .
so, the new data can be replace the oldest row in the table auto and insert into the table .
so the new row will replace the oldest 99 th row auto .the table still keep 100 row but the data can be update .
Is it "partition" or other ??
how can I create it .
Need to generate auto number as below
A00001 to A99999. After A99999 it should begin with B00001 and ends with B99999. till Z99999 we need to generate.
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,
[Code]....
So for example the first record would appear as:
PAYMENTNO CARDNO AMOUNT CARD_TYPE
======== ===== ====== =======
01
I would then enter values and the next payment number would be 02 etc.
PAYMENTNO CARDNO AMOUNT CARD_TYPE
======== ===== ====== =======
01 123412 £40.00 VISA
02
Visual Basic will usually have a star (*) beside a new entry field so 02 will be
* 02
etc........
I have about creating a sequence. So how can I tie this to my table?
I have 2 tables where the data is related.table ot_pack_list,ot_delv .ot_pack_list contains details of items information that are packed to be delivered sometimes what happens user may remove some items from this, and the summary column of dl_wt and dl_qty in ot_delv must get automatically changed whenever there is addition in ot_pack.
create table ot_pack_list (item varchar2(12),pack_qty number,pack_wt number,pack_no number)
insert into ot_pack_list values ('a',2,10,1);
insert into ot_pack_list values ('b',3,55,1);
create table ot_delv (d_no varchar2(12),d_qty number,d_Wt number,d_pack_no number)
[Code]...
--after updating the data in ot_delv should be like..
select * from ot_delv;
d_no d_qty d_wt d_pack_no

What does mean AUTO EXTEND ON ? What is purpose ?
For eg :
I'm creating a table space with 5M size . i can insert rows still 5M getting fulled then what is the purpose of autoextend ?.
I'm reading documented but couldn't understand clearly..
I was reading about Oracle SPM feature, but i have questions in mind for automatic feature..
* if we have set both capture and use parameter true. Oracle will automatically capture Plans, but will it automatically evolve new plans to accepted or it will wait for evolve it manually before using new plan.
* If it Automatically evolve, when and how will it?
* If it Automatically, will change old plan's flag accepted to No? or add one more accepted plan
