triggers

问题 Hope you can help. Is there a way to reliably detect when a stored proc is being run on SQL Server without altering the SP itself? Here's the requirement. We need to track users running reports from our enterprise data warehouse as the core product we use doesn't allow for this. Both core product reports and a slew of in-house ones we've added all return their data from individual stored procs. We don't have a practical way of altering the parts of the product webpages where reports are

问题 I am trying to write a trigger to populate a table containing information on an employee's updated salary. I'm having a problem that I can't quite wrap my head around at the moment. Here is the table to be populated: drop table SalUpdates cascade constraints; create table SalUpdates( SalSSN char(9), newSalary decimal(10,2), oldSalary decimal(10,2) ); This is my trigger: create or replace trigger t1 after update of salary on employee for each row begin insert into SalUpdates values (:old.Ssn,

问题 I am using Jenkins with Perforce. I have downloaded the P4 Plugin, and I have read over the documentation but I am still a bit confused. In my Jenkins project, I have the build trigger set to "Perforce triggered build". I'm assuming that means I need to add a trigger to Perforce that tells Jenkins to run a build, but I have no idea on how to do that. I have not been able to find any documentation on how to implement a trigger from Perforce to notify Jenkins it needs to run. I can find

问题 (Sorry for the long post, but I guess all the information is really necessary) We have two tables - task and subtask. Each task consists of one or more subtasks, and each of these objects has a start date, end date and duration. Additionally, subtasks have a ordering. Tables create table task ( pk number not null primary key, name varchar2(30) not null, start_date date, duration_in_days number, end_date date, needs_recomputation number default 0 ); create table subtask ( pk number not null

问题 So I have a Google Form-bound script that creates an installable trigger every time the Form is submitted. Now, I shared both the Form and the script to the actual users. At some point I have noticed that new triggers are not being created because quota limit is already reached. As I reviewed the list of installed triggers, I noticed that all of them are installed as "Me". How do I do it so that the other users who actually submitted the form (and created the installable trigger in the

问题 I am trying to update a table whenever a new row is inserted into another table. When a row is added to the storeRoutes table, I want this trigger to update a column in my productList table.

Here is my trigger: CREATE TRIGGER [setIsAvailableFalse] ON [storeRoutes] AFTER INSERT AS BEGIN SET NOCOUNT ON; UPDATE productList SET isAvailable = 0 WHERE productId = Inserted

问题 I want to create a trigger to display the message “NEW EMPLOYEE DETAILS INSERTED”, whenever a new record is inserted into Employee table, and have this code for it- set serveroutput on; create or replace trigger display_message after insert or update on employee for each row when(new.emp_id>0) begin dbms_output.put_line('new employee details inserted'); end; But this isn't giving me any output.
