UPDATE statement: Use the UPDATE statement to modify data in a table by specifying the column to be updated and its new value.
Constraint: by defining constraints (such as primary keys, unique constraints, foreign key constraints, etc.), updating operations can be limited to ensure data integrity.
Trigger: A trigger can be activated when updating data, causing a series of actions to be executed.
View: When updating a view, one must adhere to the view’s update rules, which typically correspond to update operations on the base table.
Rule: A set of rules that can be executed during update operations, similar to triggers but more flexible.
With clause: Using the WITH clause in an UPDATE statement allows for specifying certain special options for the update operation, such as concurrency control.
Permission: When updating data, it is necessary to meet the corresponding permission requirements to ensure that only appropriate users can perform update operations.
