Create Table To Increment ID?
Sep 1, 2012
I am trying to create a table that will increment my ID by one using the following commands:
/*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.

Step1
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.

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'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 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;
/
write a trigger that achieves the above

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?

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

We have a table in the client database that has two columns - column parent and column child. The whole hierarchy of DB table dependencies is held in this table.If Report 1 is dependent on Table A and Table A in turn is dependent on two tables Table M and Table N. Table N is dependent on table Z it will appear in the db table as,
Hierarchy Table
Parent Child
Report1Table A
Table ATable M
Table ATable N
Table NTable Z
Requirement :
From the above structure, we need to build a table which will hold the complete hierarchy by breaking it into multiple columns.The o/p should look like this
-ParentChild 1Child 2 Child 3
-Report1Table ATable M
-Report1Table ATable N Table Z
Child 1, Child 2, Child 3 ....and so on are columns.The number of tables and the no of hierarchical relationships are dynamic.
SQL Statements to create hierarchy table:
create table hierarchy (parent varchar2(20), child varchar2(20));
insert into hierarchy values ('Report1','Table A');
insert into hierarchy values ('Report1','Table B');
insert into hierarchy values ('Table A','Table M');
insert into hierarchy values ('Table B','Table N');
insert into hierarchy values ('Report2','Table P');
insert into hierarchy values ('Table M','Table X');
insert into hierarchy values ('Table N','Table Y');
insert into hierarchy values ('Report X','Table Z');
Approached already tried :
1) Using indentation : select lpad(' ',20*(level-1)) || to_char(child) P from hierarchy connect_by start with parent='Report1' connect by prior child=parent;
2)Using connect by path function :
select *
from (select parent,child,level,connect_by_isleaf as leaf, sys_connect_by_path(child,'/') as path
from hierarchy start with parent='Report1'
connect by prior child =parent) a where Leaf not in (0);
Both the approaches give the information but the hierarchy data appears in a single column.Ideally we would like data at each level to appear in a different column.

I have to create a table which contain history of a main table. like this:
if the main table is
========================
nametypelengthnot null
Avarchar5Y
Bvarchar5N
Cvarchar5N
Dvarchar5N
========================
[code]....
I've plan to so this by create a trigger in main_table. my problem is my main table have a lot of fields and I can't write a code to control it 1 by 1 like :
if old.A <> new.a
insert into history("A",old.A,new.a)
if old.B <> new.B
insert into history("B",old.b,new.b)
......
I decided to select column name from the data dictonary using this SQL:
SELECT column_name FROM user_tab_columns WHERE table_name = '<<Table Name>>';
and then do a loop over the resultset and use the column name I've got , like this (its just an idea, may be not a write syntax):
BEGIN
.....
FOR i IN 1..:result.COUNT LOOP
if ld.colname[i] <> :new.colname[i]
INSERT INTO history
VALUES ( colname[i], ld.colname[i], :new.colname[i]);
END LOOP;
END;
but I can't write a "old.colname". I try with " old.'colname' ", " ld.'colname' " but it won't work.how to create a history file like I've describe.

I want to create a new table 'b' from table 'a'.I know the query will be " create table b as select * from a;" But there is some twist in my question. I do not know how many table are there in table 'a' all I know is that there is one column named "timestamp" in table 'a'.
Now I want to create table 'b' with the difference that the column "timestamp" should contain the value "sysdate" instead of the earlier values which were there in table 'a';
Note: I have to do this in single query. I can not first create table 'b' from 'a' and then update the values of column "timestamp" to sysdate.

If I try create table from the following syntax

running on 10.2.0.5 and above satisfies the following:
having locally managed tablespace with assm enabled
create table t1 (n1 number) storage (next 1M);
insert into t1 values (1); commit;
create table t2 storage (next 2M) as select * from t1;
This will indeed set the storage option next to 2M;
The same situation in 10.2.0.4 will allways set next option for the ctas statement to the initial value of table t1.
Is this an impact of patch set 4 (10.2.0.5)? Why does it differ from 10.2.0.4 to newer releases?

creating a temporary table.i have this query mentioned below
CREATE TABLE WEBPEN AS (SELECT PNSR_PPO_NO PPO,PNSR_FILE_NO,
DECODE(F_GET_APPLN_NO(PNSR_PK),'1',PNSR_VOL_NO,F_GET_APPLN_NO(PNSR_PK)) APPLN_NO,
PNSR_FULL_NAME NAME,
TO_CHAR(PNSR_DOB,'DD/MM/YYYY') DOB,
TO_CHAR(PNSR_DOR,'DD/MM/YYYY') DOR,
F_GET_ADBK_NAME(PNSR_TO_PENSION) TREASURY,
PNSR_SPOUSE_NAME SPOUSE,
[code]....
This creates a table webpen with around 54107 rows. What i am want is every time run "select * from webpen" it should run the above query and give the result as per the values in main table M_PENSIONER ,M_PEN_DCRG_WITHHELD.
What i want is it should truncate the existing values and insert the value by running the above mentioned query .

Today I’m trying to make a “table” from a column. The information I’m using looks like:
AAA-B-CCC|DDD-E-FFF|GGG-H-III|JJJ - K
I need my table have these columns:
Column1 Column2 Column3
AAA B CCC
DDD E FFF
GGG H III
JJJ K
So I began to divide the string into smaller pieces:
SELECT LEVEL reg,
REGEXP_SUBSTR('AAA-B-CCC|DDD-E-FFF|GGG-H-III|JJJ-K','[^|]+', 1, LEVEL) ferroc
FROM DUAL
CONNECT BY LEVEL <= LENGTH('AAA-B-CCC|DDD-E-FFF|GGG-H-III|JJJ-K') - LENGTH(REPLACE('AAA-B-CCC|DDD-E-FFF|GGG-H-III|JJJ–K','|')) + 1; What I get is:
>
REG ferroc
1 AAA-B-CCC
2 DDD-E-FFF
3 GGG-H-III
4 JJJ - K
>
After this step I’m lost, I try to do almost the same thing than in the first query but mi information get mixed.
