Create Trigger To Stop Events From Being Deleted
Jun 2, 2010
I am trying to create a trigger to stop events from being deleted if the date is before the current date. This is the SQL syntax for my table
CREATE TABLE event
(event_id numeric(5) not null,
concert_id numeric(5) not null,
event_date date,
);
What I have attempted so far is:
CREATE OR REPLACE TRIGGER event_deleting
BEFORE DELETE ON event
FOR EACH ROW
BEGIN
IF DELETING THEN
[code]......
This gives me a few warnings, the first is that a DECLARE is missing and the second is a INTO is missing.

I'm trying to create a trigger so that whenever a record in the Employee table is deleted, a trigger will automatically delete corresponding records in the Job History table, then the Employee record is archived to EmployeeArchive before it is deleted. It compiles but with warnings. Here's what I've got.
CREATE TABLE EmployeeArchive
(EmployeeID Int, FirstName Char, LastName Char,
EMail Char, PhoneNumber Int, HireDate Date, JobID Char, Salary Int,
Commission Int, ManagerID Int, DepartmentID Char);
[Code]....

i want to write, just ONE trigger that handles all DMS events at schema level and writes the field changes to a specific log table. i wanna to write like 'FOR EACH FIELD' as for each row (& also each table). it turns in the fields section and if the 'old' and 'new' values isnt same, it triggers this function & writes changes to log.
ex. is like:
FOR EACH ROW
FOR EACH FIELD
if (old.value != new.value)
insert into LOG(..., old.name,new.name) values (..., old.value, new.value)
NEXT // FIELD
NEXT // ROW

Is there any way of stopping the report from executing in Before-Report Trigger.
Actually what i am doing is to see whether some records are present there in the table in Before-Report Trigger on which the report is going to print. Because I am doing some updates in After-Report trigger. I want to stop if there is no records present in the table in Before-Report Trigger so the report will not go forward to After-Trigger of the report.
how to stop and by using which statement.the other way so that if report has no data then After-Report Trigger should not fired.

This has to be done parallel for all the tables for which this flag is enabled and by that trigger delete all those rows which were backed up as table.

We 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)

table
CREATE TABLE "TEST"
("CONTRACT_REF_NO" VARCHAR2(20 BYTE) primary key,
"CHG_GL" VARCHAR2(9 BYTE),
"CHG_GL_1" VARCHAR2(9 BYTE),
"CHG_GL_2" VARCHAR2(9 BYTE),
[code]...
10 rows selected.
create or replace view test_view
as
select 1 id,CONTRACT_REF_NO,chg_gl
from test
union all
[code]...
11 rows selected.
I have done only for one id.
so the problem is the front end is showing this test_view that people will modify.but they have to actually modify the table ,so I can think of an instead of trigger(instead of insert and instead of update ones).

I gave this a shot on my own, and failed, so I am putting the question to you:
I am looking to create a trigger on the "Account" table
CREATE TABLE Account(Acct_no number, BillAmt number, OpenDate Date, SSN number,
Primary Key (Acct_no),
Foreign Key(SSN) references ResponsibleParty(SSN));
which will update the BillAmt field whenever one of the account's respective records is inserted/updated/deleted from the following tables:
CREATE TABLE Plan(Plan_id number, Cost number, Minutes number,
primary key(Plan_id));
CREATE TABLE Feature(Feature_id number, Description varchar(20), Cost number,
primary key(Feature_id));
These tables are linked through the following table:
CREATE TABLE Phone_Line(MTN number, cStart Date, cEnd Date,
rDate Date, Status char, ESN number, Acct_no number, Plan_id number,
primary key(MTN),
foreign key(ESN) references Equiptment(ESN), foreign key( Acct_no) references Account(Acct_no),
foreign key(Plan_id) references Plan(Plan_id));

Relevant tables:
create table messages
(
msgID number(10),
fromID number(10),
message varchar2(1024),
ToUserID number(10) default NULL,
ToGroupID number(10) default NULL,
dateSent date,
constraint messages_pk primary key(msgID),
constraint messages_fk1 foreign key(fromID) references profile(userID) on delete cascade,
constraint messages_fk2 foreign key(ToUserID) references profile(userID) on delete cascade
);
[code]....
I need to create a trigger that adds corresponding records into messageRecipient when a message is sent to a group. So, for example, the sql statement
insert into messages values(1, 2, 'message sent to group 3 from user 2', NULL, 3, currentdate);
should add records of the form (1, userID) into messageRecipient for every (3, userID) pair in groupMembership. Here are two triggers I've tried, neither of which works.
create or replace trigger SendGroupMessage
after insert on messages
FOR EACH ROW
when (new.ToUserID is NULL)
BEGIN
insert into messageRecipient(msgID,UserID)
[code]....
