triggers

问题 I was working on my project, here I got this error while inserting some values in a row: ERROR at line 1: ORA-04091: table SYSTEM.PRODUCTS is mutating, trigger/function may not see it ORA-06512: at "SYSTEM.PROD_TOTAL", line 2 ORA-04088: error during execution of trigger 'SYSTEM.PROD_TOTAL' This is my insert statement: insert into products values (1, 1001, 'Medical', 20, 4, 1, 1, 1); Products table : create table Products ( ProdId number primary key, ProdNum number not null unique, ProdType

问题 I'm very new to scripting so if anyone knows how to do this it'd be great help! I have a user that logs in on business days at ~9 am, and has to do something before 9.30 am. To remind and insist that it's done I want to have an alert that says to do it, if a certain cell is not empty. Ideally it would check at 9, 9.10, 9.20 and 9.30, and pop up each time until it's done. I tried to set up a trigger every 10 minutes, but I read that you can't use triggers with UI. function startCustomTrigger()

问题 I want to create a trigger with dynamic SQL where I get a column name from a variable. Here is my simplified mysql schema: CREATE TABLE products (id int); INSERT INTO products VALUES (1),(2); CREATE TABLE attribute_values (product_id int, `key` varchar(100), value varchar(100)); INSERT INTO attribute_values VALUES ( 1, 'title', 'Orange'), ( 1, 'code', 'O125'), ( 2, 'title', 'Pizza'); CREATE TABLE product_attributes SELECT products.id, MAX(CASE WHEN attribute_values.key = 'title' THEN

问题 I have a typical LAMP based site + Zend Framework where I have a base table and a summary table. Summary table is used to display data in reports. Base table - ID | Status 1 | 1 2 | 1 3 | 2 4 | 2 5 | 1 6 | 1 Summary table - Status | Count 1 | 4 2 | 2 The base table will be changed(insert,update,delete) at an average of 20 times per day. Currently, I am using triggers to call a stored procedure which will update the summary table based on the base table. This is the stored procedure. CREATE

问题 How can I programmatically delete a Google Apps Script time-based trigger by the triggered function's name, instead of triggerarray id? I am creating a trigger and later on I want to delete the trigger by name. I tried this: ScriptApp.deleteTrigger("myfunction"); but it does not work. I don't want to use this method: var triggers = ScriptApp.getProjectTriggers(); ScriptApp.deleteTrigger(triggers[0]); Since I have more than one trigger at same time and might delete the wrong one! So how to

问题 I have a bash script where I want to trigger a method every time the filesystem is changed: #!/bin/bash function run { echo Do some magic // Do some magic } run fswatch . src | 'run' In this case I am watching the src folder. When I trigger the script via ./automater.sh the script executes the run function the first time correctly and when I then change some file, the script simply exits... 回答1: BUT then it runs in a loop.... , I also hit this, because after your ./automater.sh execution,

问题 My trigger in Oracle looks like this… CREATE OR REPLACE TRIGGER example$example BEFORE UPDATE OR DELETE ON example FOR EACH ROW BEGIN INSERT INTO example$ VALUES ( :old.key, :old.name, :old.describe seq.nextVal ); END; I thought I could simply translate to Postgresql with this… CREATE OR REPLACE TRIGGER example$example BEFORE UPDATE OR DELETE ON example FOR EACH ROW BEGIN INSERT INTO example$ VALUES ( OLD.key, OLD.name, OLD.describe, NEXTVAL('seq') ); END; I'm getting an error at the end of

问题 I want to execute a google apps script whenever a new file is added to a specific folder. Currently I'm using a run-every-x-minutes clock trigger, but I only need to run the script whenever I add a file to a folder. Is there a way to do this? The same as this question - which is now almost 3 years old. The comment below the question states that: There's not a trigger for that, if that's what you're hoping. How are things getting into the folder, and do you have any control over that? – Jesse
