triggers

问题 Hi I have the following code: function onEdit(e) { if (e.value == "Requested") { var number = 50; // Number of blink for (var i = 0; i <= number * 2; i++) { if (i % 2 == 0) { var color = "white"; } else { var color = "red"; } e.range.setBackground(color); SpreadsheetApp.flush(); Utilities.sleep(1500); // Blink speed (ms) } e.range.setBackground("white") // Cell color is white after blinks were completed. } } However for some reason the cell blinks less than 10 times or so even though I have

问题 long time lurker but first question. Finally figured out how to maintain a changelog by trigger on this question Embedding record from function in OrientDB But I'd also like to maintain the user updating the record, and maybe other metadata like which props were updated. My use case is passing batches of upserts from c# using HTTP requests with a JSON array of commands, into some base classes as follows: ALTER CLASS V SUPERCLASS +OTriggered CREATE CLASS ChangeHistory ABSTRACT CREATE PROPERTY

问题 When a new row is added to our Postgres database, I want to run a bash script. Is there any sort of system() function in PostgreSQL that would allow me to do this? To give more context, when a new row is created in the database, I need to make a new file containing information from that row on an external server via SSH. An alternate solution would just be to have a cron job run every 5 minutes or so and check for new rows, but then it might not catch if someone deletes a row, and then adds a

问题 I am making a trigger to alter a table that adds a new column to it and inserts the value in it.

问题 I am writing a trigger to UPDATE a row in a table AFTER INSERT on another table. Here are the scripts of the tables: Table inv_cost CREATE TABLE inv_cost ( Username varchar(20) NOT NULL DEFAULT '', MachineType varchar(2) NOT NULL, Cost smallint(4) NOT NULL DEFAULT '0', PRIMARY KEY (Username,MachineType), ) Table investigation CREATE TABLE investigation ( Username varchar(20) NOT NULL, MachineType varchar(2) NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1; DELIMITER ;; CREATE TRIGGER TRG1

问题 Inside this object, I have a property Response.action that is meant to be a shorthand for triggering code on jQuery's .ready and .resize simultaneously. The comment in the code block below demonstrates its usage. Response.action works on .ready but not on .resize . Can anyone see why and/or suggest how to make it work for both? window.Response = (function($, window, undefined) { var Response = {}, // object $window = $(window), $document = $(document); // cache selectors /* Response.action()

问题 Here's my problem: I have to transform something like this Into this in the same table I've tried triggers but I have mutating issues, I have no control about the inserts but I need to do that for every row with value larger than 1. Any sugestions? 回答1: Depending on the number of transactions you're looking at, it may not be a feasible approach, but you might try something along these lines: CREATE OR REPLACE TRIGGER {TRIGGER NAME} BEFORE INSERT ON {TABLE HERE} FOR EACH ROW DECLARE l_val

问题 My Problem I want to model a block called "confirmer". The specification is that the output will SIMPLY be the delayed version of input based on an edge (rising/falling). To clarify, I will try to put the timing diagrams below: ___________________________ | | Input _______| |____________________________ (Tdelay) _____________________ | | Output ______________| |____________________________ And ____________________________ | | Input _______________| |____________________________ (Tdelay) _____

问题 I'm doing a trigger on my Oracle database, here's the code CREATE OR REPLACE TRIGGER send_telegram_message AFTER INSERT ON EVENT_LOG FOR EACH ROW DECLARE GROUP_IDS VARCHAR(200); BEGIN IF :NEW.EVENT_ID AND :NEW.DESCRIPTION IS NOT NULL THEN SELECT ID_GRUPO INTO GROUP_IDS FROM V_EVENT_TELEGRAM WHERE V_EVENT_TELEGRAM.EVENT_ID = :NEW.EVENT_ID; TELEGRAM_BOT(GROUP_IDS,:NEW.DESCRIPTION); END IF; END; When compile I'm getting the following error: Error(4,3): PL/SQL: Statement ignored Error(4,6): PLS
