SQL & PL/SQL :: How To Create Identity Function In Oracle
Apr 15, 2010
i have a project that needs to have a identity number in the table.this is the table:
create global temporary table BOOK_INFO
( row_id number(5),
BOOK_TITLE char(20),
BOOK_AUTHOR char(15)
) on commit preserve rows;
i dont know how can i generate row_id, in sybase i can only set the datatype of row_id in IDENTITY and it will automatically generates number and as the transaction ended the row_id will automatically back to 1.
in oracle i tried to create sequence but it didnt back to 1 when the transaction/procedure ended.. Like for example if the procedure ended and the last row_id inserted in the table is 300 the next run of the procedure will start in 301. but i need to start in 1 in every run of the procedure.
Also, i tried to set the variable v_row_id to 0 and it increment by 1 as it insert in the table, but the problem is there are times that in 1 book_title there is more than 1 author. so the v_row_id of the book_title with more than 1 author is all the same.Here is my query:
insert into BOOK_INFO
(select v_row_id, BOOK_TITLE, BOOK_AUTHOR from LIBRARY);
My company has a "generic information management platform" based on Oracle,
including:
Oracle Identity Manager 10g Lotus Oracle Internat Directory 10g Oracle Portal 10g Oracle E-Business Employee Oracle E-Business User Management Microsoft Active Directory Mail System Oracle Database
All above these systems constitute the generic information management platform. --------------------------------------------------------------------------------------- There are 60,000 user records in the Oracle Database, lots of user records are duplicate, invalid and redundant. We want delete them by Oracle Identity Manager. But Oracle Identity Manager has no bulk deletion of users function!!!
So, we want customized development this generic information management platform, specifically customized development Oracle Identity Manager 10g's administrator interface.
We want add a JSP page, use this JSP page to bulk delete users. (user number > 60,000) ---------------------------------------------------------------------------------------- What's should we do? We can't directly manipulate the database to delete the users, all users are associated by API and exist in many systems. ----------------------------------------------------------------------------------------
I am trying the new Oracle 12c and its feature to create columns with the keyword IDENTITY. I create a table CREATE TABLE xt (a NUMBER GENERATED by default AS IDENTITY PRIMARY KEY, b VARCHAR2(10));
And populate it, sometimes specifying the value for a and sometimes relying on the system to generate the value:
INSERT INTO xt (b) values ('a');INSERT INTO xt (b, a) values ('b', default);INSERT INTO xt (b, a) values ('c', 3);INSERT INTO xt (b) values ('d');INSERT INTO xt (b) values ('e');
The problem is that the fourth INSERT fails because the system tries to use the value 3 which is already taken. The fifth statement gets the value 4.
And the table now contains: A B - -1 a 2 b 3 c 4 e Is there something I am missing? I understood that by specifying BY DEFAULT, I would be allowed to sometimes specify values on my own without them interfering with the generated values. I now that the same thing works correctly in MySQL (where I would get five rows from 1 to 5 with the same INSERT statements) /nikos
i created one table which has id with number datatype for which i created sequence and stored procedure so suppose i inserted two row there it's inserting and id is showing 1, 2 again i truncate that table and again i inserted value there now the id is starting from 3 , 4 so my question is that after truncating table can't it insert from 1 in id column?
i want to create a function that build a return xml (XmlType):
create or replace function plainLanguageSummary(nip varchar2,id number,code_language varchar2) return XmlType as
[Code].....
but in the compilation i got the following error :
Error(10,62): PLS-00103: Encountered the symbol "SELECT" when expecting one of the following: ( - + case mod new not null others <identificateur> <identificateur entre guillemets> <variable bind> avg count current exists max min prior sql stddev sum variance execute forall merge time timestamp interval date <un littéral de chaîne avec spécification de jeu de caractères> <un nombre> <une chaîne SQL entre apostrophes> pipe <constante de chaîne éventuellement entre guillemets avec indication du jeu de
he seems to not like the first "select" he encounter!.
A B ---------------------- 2*3 2*4*5 4*5 column B contain no data.
I want to create a function which can be used in a select query,and the output should come like that :-
A B ---------------------- 2*3 6 2*4*5 40 4*5 20
Means column B contains the resultant value of column A.And the above output should come through a select statement.You can use any function inside the select statement.
I am using a form which create function to calculate value using form_ddl. When I used this program from superuser it will calculate correct value but in other user it calculate wrong value. I gave 'Create Procedure ' privilege to user too.But still problem exist.
I made this script but I still don't quite understand if the syntax is correct. I just wanted to create a function and call it in an anonymous block. I then wanted it to use a variable as a parameter in an iteration and output the variable every iteration. It's done basically but I know it's not 100% right. The fibonacci function looks like its going to loop an infinite number of times if the parameter is greater than 2.
CREATE OR REPLACE PACKAGE myPACKAGE AS CREATE OR REPLACE FUNCTION fibonacci (n BINARY_DOUBLE) RETURN BINARY_DOUBLE IS BEGIN IF n <= 2 THEN RETURN 1; [code]........
I want to build a custom authentication scheme which combines the funcionality of of SSO and a custom authentication function.
1. If the HTTP Header Variable REMOTE_USER is set, this user should be a valid logged on user. (Single Sign On functionality)
2. If the HTTP Header Variable is not set, the LOGIN-Page should appear. (local user Administration)
3. The user/password combination from the login page should be validated by my own authentication function I think I have to create a sentry-Function, which is a combination of the sentry-functions which are used in the schemes "custom" and "HTTP Header Variable". I tried to find an implementation of these functions in the APEX_040200 database scheme, but without success.
Using oracle 10g R2 on sun-solaris 10 (sparc-64) Well in the MIS system we have lot of ad-hoc queries coming up. We have proper indexing. Say an example which runs very slow;
Here GLUPMJ already indexed so the second query returing an index scan but the first query does a FTS naturally.Now even if I plan to create a function based index on 'the bold highlighted' but how.
create index glupmj_idx on f0911(TO_DATE('1 JAN' || (19+substr( GLUPMJ , 1, 1)) || substr( GLUPMJ ,2,2)) + substr( GLUPMJ , 4, 3 ));..Error If I don't use a FBI my query will result in FTS.
1> how to create a FBI here in this case
2> In MIS systems where 'n' no of ad-hoc queries can come up, how to avoid FTS.
I have a series of SQL scripts which contain SQL statements to create tables, populate them, create functions and stored procedures. Now I would like to execute each sql file against SQLPlus using a batch file so that I can just run this one file and all the configuration work I need to do can get done.
Problem is, when I try to execute the SQL file against SQLPlus, it gets upset with the Create Procedure/Function scripts...
I am using the following command:
sqlplus u/p@<someserver> @<path_to_sqlfile>.sql
this sql file contains create procedure pl/sql code
Is it possible create/compile SP/Functions that are contained within SQL Files using SQLPLus? Or do I have to physically write them out in SQLPLus (or load them in SQLDeveloper) to accomplish this?
I need to create PROCEDURE to create user in oracle
CREATE OR REPLACE PROCEDURE "CREATE_USER_ORACLE8" ( USER_ID in VARCHAR2, PASSWORD in VARCHAR2, ROLES in VARCHAR2, nReturnCode OUT NUMBER ) BEGIN [code].......
Compilation errors for PROCEDURE NOG.CREATE_USER_ORACLE8
Error: PLS-00103: Encountered the symbol "BEGIN" when expecting one of the following:

i want that the customer execute PROCEDURE (user_id,password,PROCEDURE )
I am trying to execute dynamic SQL in Stored Function and I don't know how to do this.
Explanation:
In the function I am calling pr_createtab is procedure which will create a physical table and return the table name in the out variable v_tbl_nm.
I need to query on this dynamic table and return the result as return result. But i am not able to do it.
Here T_web_loylty_report_table is a type.
CREATE OR REPLACE function CDW_DSS.f_ReturnTable(i_mrkt_id in number, i_cmpgn_year in number) return T_web_loylty_report_table is v_tbl_nm varchar2(50); i_cntry_cd varchar2(20); v_sql_str varchar2(32567); [code]......
I have a dynamic query stored in a function that returns a customized SQL statement depending on the environment it is running in. I would like to create a Materialized View that uses this dynamic query.
I have a requirement to put together a Oracle SQL template to create re-usable DDL/DML Scripts for Oracle databases.Only the Oracle DBA will be running the scripts so permissions is not an issue.
The workflow for any DDL is as follows:-
1) New Table
a. Check if the table exists from the system/admin views.
b. If table exists then give message "Table Exists"
c. If table does not exist then execute DDL code
2) Add Column
a. Check if Column exists for a given table from system/admin views
b. If column exists in the specified table,
b1. backup table.
b2. alter table to make changes to the column
b3. verify data or execute dml script convert from backup to the new change.
c. If Column does not exist
c1. backup table
c2. alter table to add column
c3. execute dml to populate column with default value.
The DML scripts are for populating base tables with data required for business operations.
3) Add new row
a. check if row exists by comparing old values of each column with new values to be added for the new record.
b. If exists, give message row exists
c. If not exists, add new record.
4) Update existing record (We have createtime columns in these tables so changes can be tracked)
a. check if row exists using primary key.
b. If exists,
b1. deactivate the record using the "active" column of the table
b2. Add new record with the changes required.
c. If does not exist, add new record with the changes required.
I am using lag function to display values like below:
order details date starttime ----------------- -------- -------------- main order 1 07/10/12 06:00am line 1 07/10/12 06:21am line 2 07/10/12 06:31am main order 2 07/11/12 07:00am line 1 07/11/12 07:01am line 2 07/11/12 07:02am
the data displays correctly when i use lag function except that the line 1 details are never getting displayed ie first line under every order does not get displayed? is using lag function in this case correct?
I have written a query which basically retrieves id and created date. IF i put MAX function it is returning id which have max created date. But if i use min function this query is not providing id with min created date,its not returning any rows.
SELECT To_char(OSH.osh_id), OSH.osh_created FROM tn_order_status_history osh, tn_order_status_type ost, tn_orderline_product op [code]..........
Well the company i work for has just recently upgraded from Oracle 9i to 10g. We are having various problems with the migration, and with certain code breaking. My question regards this piece of code;
[code]
to_number(to_char('a_date','YYYY'))
[code]
There are various statements like the one above scattered throughout a query i am trying to fix. When run, the query returns an "invalid number ora-01722" error, which i know is caused by the above code.
if this method of converting from date, to character was discontinued from 9i to 10g?it just seems strange as there are a lot of statements like the one above and they must have worked at some point, but now i cant even get one to work on its own.
CREATE OR REPLACE FUNCTION get_project_id( schema_p IN VARCHAR2, table_p IN VARCHAR2) RETURN VARCHAR2 IS projects_pred VARCHAR2 (400); [code].......
I am trying to get the projects a user has from the works_on table (user_id, project_id). The user_id is retrieved from the context projects_ctx. I am getting the error Function created with compilations errors.
CREATE TABLE TEST1 (AGG_DATE DATE, COL1 NUMBER(9), COL2 NUMBER(9), COL3 NUMBER(9)); Here is the test-data population script: insert into TEST1 (AGG_DATE, COL1, COL2, COL3) values (to_date('01-01-2012', 'dd-mm-yyyy'), 1, 1, 1); [code]....
The problem is when I wrote an analytical query, it is giving the BEGIN_DATE and END_DATE by taking all the partition values together and so instead of the values above, it is creating an answer as follows:
I have an oracle package that i am using to search for a string in a blob entry. I compiled the package and the package body in one environment, it had no errors, when i execute, i get my results.I went ahead and created the same package and function in another environment and it fails by giving me the below error
ORA-06503: PL/SQL: Function returned without value ORA-06512: at "SYSTEM.IMPACTUS_PCODE", line 158 for sysadm
I have used this on other environments often and have never had an issue.
when i press the save button in my application the record will be saved but the value in my "display item" wont be refreshed. when i minimize the form designer and maximize it again, the "display item" is refreshed.
I have a table with date column (16/06/1996 15:03:59) as value in the displayed format. As I have tried with the below query format I could not able to retrieve the
records. select * from <table> where DATE_INSERT=SYSDATE;
