triggers

问题 New to jQuery/javascript, but not too afraid... Friend helped me out with the slideshow script below, and I've pulled jellekralt's Responsive Tabs jQuery script from github... I have the javascript, auto-playing, crossfading slideshow that loops images (specified in each page's html file (in js-determined random order, FWIW)). I had main section pages linking out to subpages, with different images than the main pages' in each subpage. But now I've chosen to use the Responsive Tabs jQuery code

问题 The following triggers are meant to automate updates when a row is updated in a locations table. Changes can occur one row at a time, or 1-n many rows at a time. However, when updating a single row, while the "locations_geteditdate" is enabled, a new time stamp is written to all 28K rows in the locations table. I know I'm missing something obvious here, thanks for the help. ALTER TRIGGER [dbo].[locations_geteditdate] ON [dbo].[TBL_LOCATIONS] instead of update AS begin declare @recs INT select

问题 I want to implement an audit log using triggers which gets fired on created, changed and deleted data to store some values. Those triggers should be able to use user ids which made the changes and which are managed by the web application. I have some ideas on providing this data, but I don't seem to fully understand what the execution context of a trigger is. I've read through the PostgreSQL docs Overview of Trigger Behavior and others but my question doesn't seem to be answered. What I want

问题 Hi everyone getting this error message when trying to create a trigger and its got me a little stumped. Here is my trigger code. CREATE OR REPLACE TRIGGER CUSTOMER_AD AFTER DELETE ON CUSTOMER REFERENCING OLD AS OLD FOR EACH ROW DECLARE nPlaced_order_count NUMBER; BEGIN SELECT COUNT(*) INTO nPlaced_order_count FROM PLACED_ORDERS p WHERE p.FK1_CUSTOMER_ID = OLD.CUSTOMER_ID; IF nPlaced_order_count > 0 THEN INSERT into previous_customer (customer_id, first_name, last_name, address, AUDIT_USER,

问题 CREATE TRIGGER b_I_O AFTER UPDATE ON book FOR EACH ROW BEGIN IF (OLD.status IS NOT NULL AND NEW.status IS NOT NULL AND NEW.status != OLD.status ) THEN INSERT INTO book_in_out (astatus, bid, time) VALUES(NEW.status, OLD.id, NOW()); END IF; END; First post here after hours of searching. I'm trying to insert into book_in_out using trigger after updating booking table, I was able to do this but if I update bookName the trigger will try to run. I only want the trigger to run only when status

问题 have a very easy question, but it seems I could not find the answer on the Internet for it. Possibly because I am not looking in the right places. I have a user control with a DependencyProperty of a custom enum type. In XAML I would like to Show/Hide elements based on the value of the enum type. I tried to do this with DataTriggers but I fail to get it working. <UserControl x:Class="WpfApplication1.DisplayIcon" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http:/

问题 I've created a basic audit table so that if there any any changes to a 'Employee' table be they insert, update, delete, the time, the user and what the action is are stored in a 'audit employee' table. I just wondered if it was possible so that the trigger would only fire if the changes made on the 'Employee' table were after say 5pm until 7am? Does anyone have any ideas how this would be possible possibly using SYSDATE? Thanks 回答1: You cannot control whether the trigger will fire based on
