Oracle row-level triggers have the following characteristics:<\/p>\n

    \n
  1. Trigger Timing: Row-level triggers are activated whenever there is a change in each row of data, enabling corresponding operations to be carried out before or after data insertion, update, or deletion.<\/li>\n
  2. Trigger condition: Row-level triggers can execute trigger logic based on specific data changes when certain conditions are met, such as when the values of a column meet a certain condition or when a combination of multiple columns meet a certain condition.<\/li>\n
  3. Accessing data from the triggered table: Row-level triggers can access data from the triggered table by referencing the NEW and OLD pseudo records. The NEW pseudo record contains the new data after insertion or update, while the OLD pseudo record contains the old data before update or deletion.<\/li>\n
  4. Trigger sequence: If multiple row-level triggers are associated with the same table, their trigger sequence can be specified. Oracle database will execute them in the order they were created.<\/li>\n
  5. Data consistency: Row-level triggers can perform operations before or after a data change, which can be used to maintain data consistency such as checking and correcting data integrity, or computing derived data.<\/li>\n
  6. The lifecycle of a trigger: the lifecycle of a row-level trigger is consistent with that of the associated table, with triggers automatically being deleted when the table is deleted.<\/li>\n
  7. The replaceability of triggers: Row-level triggers can be controlled by disabling or enabling them, as well as by modifying or deleting to change the trigger logic.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
