Difference between Row level and Statement level triggers

Triggers are defined as stored programs which are automatically executed whenever some events such as CREATE, ALTER, UPDATE, INSERT, DELETE takes place.They can be defined on a database, table, view with which event is associated. 

Triggers can be broadly classified into Row Level and Statement Level triggers. 
Broadly, these can be differentiated as:

Row Level Triggers	Statement Level Triggers
Row level triggers executes once for each and every row in the transaction.	Statement level triggers executes only once for each single transaction.
Specifically used for data auditing purpose.	Used for enforcing all additional security on the transactions performed on the table.
“FOR EACH ROW” clause is present in CREATE TRIGGER command.	“FOR EACH STATEMENT” clause is omitted in CREATE TRIGGER command.
Example: If 1500 rows are to be inserted into a table, the row level trigger would execute 1500 times.	Example: If 1500 rows are to be inserted into a table, the statement level trigger would execute only once.
