Can triggers handle more than one operation at a time?
Each trigger would handle multiple unrelated items of business logic.
Can we have multiple triggers in the same table?
SQL Server allows multiple triggers on the table for the same event and there is no defined order of execution of these triggers. We can set the order of a trigger to either first or last using procedure sp_settriggerorder. There can be only one first or last trigger for each statement on a table.
How many different triggers a table can have list all of these?
In SQL Server we can create four types of triggers Data Definition Language (DDL) triggers, Data Manipulation Language (DML) triggers, CLR triggers, and Logon triggers.
How many triggers are possible per table in MySQL?
SIX triggers are allowed in MySQL table.
What happens when a trigger is not compiled?
A trigger is compiled when it is created. Thus, if a remote site is unavailable when the trigger must compile, then Oracle Database cannot validate the statement accessing the remote database, and the compilation fails. The previous example exception statement cannot run, because the trigger does not complete compilation.
Why does sqlServer compile each time it is triggered?
It does compile each time, but I hadn’t checked if a trigger compiles each time it is triggered when it doesn’t reference the DMV and instead hardcodes a value. It was still compiling each time it got triggered. Dropping the trigger stops the compiles. We are using sqlserver.query_pre_execution_showplan in an XE session to track the compilations.

When to use a trigger in SQL Server?
Sometimes it is known as FOR triggers. Example: When we insert data into a table, the trigger associated with the insert operation on that table will not fire until the row has passed all constraints, such as the primary key constraint. SQL Server cannot fire the AFTER trigger when the data insertion failed.
