. Implement complex non-standard database-related integrity rules. Triggers can be used for serial updates of related tables in the database. For example, a delete trigger on the Auths table author_code column causes the corresponding row to be deleted in the other table.# cascade Modify or delete rows in other tables that match them when modified or deleted.# Sets the row in the other table to a null value when modified or deleted.# Sets the row cascade in the other table to be the default valu

assignment in a trigger so that the trigger is not triggered again, causing a circular call (such as adding "2013" to the student's number before each insert). View triggers and view the database (show databases;) to view the table (show tables;), the syntax for viewing the trigger is as follows: SHOW TRIGGERS [from schema_name];Where Schema_name is the name of the schema, in MySQL, the schema and database are the same, that is, you can specify the name of the databases, so that Without first "

W.amount ->set new.amount = 0; , ELSEIF new.amount > Then ->set new.amount = +; ->end IF; end;// mysql> delimiter; the simpler way is to define the stored program separately, The stored program is then called from the trigger using a simple call statement. This method is also helpful if you are going to invoke the same subroutine from within several trigger programs. During the execution of the trigger, MySQL handles the error as follows: (1) If the before trigger fails, the action on
