triggers

问题 For example : A user should not be able to perform INSERT , DELETE and UPDATE operations more than X number of times on a particular table at a given point of time, if the user performs an operation X +1 times than a trigger will be launched. 回答1: create table dbo.targetTable ( id int, colA varchar(10) ); go create or alter trigger dbo.DMLxTimes on dbo.targetTable for insert, update, delete as begin /* --old days.. IF @@ROWCOUNT > 5 begin rollback; end --*/ declare @maxrows int = 5; --maximum

问题 I have a situation in which I want to update a the second table when a row of data is inserted in the first table.

问题 I have a problem with this trigger. When I use the INSERT and the SIGNAL statements inside the IF condition, the insertion is not performed. However, without SIGNAL, the insertion is done. Anyone have an explanation for that? My main concern is that I need both the insertion and the SIGNAL statement to cancel the main insertion (the insertion that throws the trigger) DELIMITER // CREATE TRIGGER log_venta BEFORE INSERT ON `venta_producto` FOR EACH ROW BEGIN DECLARE value int; DECLARE valor
