I want to create a trigger with the requirement of achieving Primary key functionality.
I have a "EMP" table. the table already contains a duplicate data on "EMPNO" column. i want to restrict entering duplicate data further into table for that i want to create a trigger.
where can i find different triggering events of DML(like update, delete etc...)and DDL(database and schema level).
I have a form with fields like, UserName, User ID Email Address. This is used to create new users & edit existing user information. I wanted to make the Email field mandatory. So i made the email field as 'Required' via Proerty Pallette. So when ever i create new users after this change, i get a message saying 'Field must be required' when i try to skip this email field.
However when i edit existing user information and try to save the data with no email address i am able to save. So, where when i try to save a user info with no email address, i should get a warning saying 'email address is required'. How to go about it and if i wil have to create any trigger.
I am trying to handle PK violation error on a certain table, on INSERT, my best guess is I should use a trigger. The basic idea is this:
The table consists of 7 columns, and 6 of them are PK, and the seventh one is "amount". I want to handle PK violation in such way that, if it occurs during INSERT, then instead of inserting a new row, it should just update the "amount".
I have a SQL link table called student_monitor containing the follwing attributes and e.g. data
student_id, Class_id, Predicted_Grade, Actual_Grade
1 1 A C
2 1 B B
3 1 C B
I need to be able to flag which students are under achieving on their target grades and dont know how to do this or the best way to do this as i cannot calculate the diff between a char?
primary key should be
W1
W2
W3 like this.
1,2,3 are sequence numbers.
A Master form in a tabular format. Id is a display item. I want to auto generate Id with following query.
select nvl(max(issue_id),0)+1 into :issue_mt.issue_id from issue_mt;
It works:
1)When each record is saved before creating new record.
It doesn't work:
2)If multiple records are entered with out saving each record.
What to do to generate unique Id in both cases?
how to create a primary key with out creating an index?
View 10 Replies View RelatedCreate table X(
var1 varchar2(20) null,
var2 varchar2(20) not null,
constraint pk_var1 primary key(var1)
We all know Primary key doesnt treat NULL as a value. But the above statement is fine to be executed without problem.
Is this something to be highlighted? or am i not right in understanding 'var1 varchar2(20) null '?
I have to create primary key using local on a partitioned table.
Since the table is huge it has to be done parallel. Following stmt is giving error
alter table XYZ add CONSTRAINT PKN_XYZ PRIMARY KEY (ID,LogDtTm)
USING INDEX LOCAL parallel 25 INITRANS 5 TABLESPACE OLTP_IDX_TS ;
i'm new to oracle environment.how can i specify NONCLUSTERD INDEX on Primary cloumn during table creation.By default it will create clusterd index but i need non-clusterd index on it.
I'm using following stmt to create normal primary constarint during table creation,
CONSTRAINT PKFORM_PROPS PRIMARY KEY (FORM_PROPS_PK) USING INDEX TABLESPACE DB123_INDEX
how can i change the above query, so that it should create NONCLUSTERED INDEX on Primary key column.
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?
What is difference when you issue a create controlfile with "standby" keyword on the primary database
ALTER DATABASE CREATE STANDBY CONTROLFILE AS '/path/db_stby.ctl';
vs. creating a control using
ALTER DATABASE BACKUP CONTROLFILE to '/path/db_control.ctl';
what does ORACLE put into the standby control that is "extra"? ie. what is the difference between a standby control file and a normal control file?

View 4 Replies View RelatedWe have an application is must be connected to our database for specific requirements in our company but this application has a very bug thing as we must write the super DB password "Like HR password as example" clear in some files and these files must be shared so developers can use the HR password to do any action !!! I know that this application is a problem but we have to install
I can do this by creating trigger on each table will restrict DML. As example: if the operating system user is XXX, the trigger restrict the action. But not logic at all to create more than 1000 triggers on schema (This will impact badly on DB performance).
So, i need to create one trigger to fire before doing any DML on all schema tables. As example: If "MMM" the administrator operating system user trying to do insert action, he can do the action. BUT If "DEV" the developer operating system user trying to do insert action, the trigger must fire here to restrict this action.
Be noted also, i need this trigger not depend on any specific tool like Toad as any user can simply rename the exe file for toad then he can pass the trigger. At least, trigger must depend on (Operating system user & Action_type)
i want to give privilege of create trigger,procedures and functions privileges to a user "A"on the schema "B". how can i do it. i've already given select,insert,update,delete privilege to user "A"
