of an element in an array that matches the COUNTRY_ID key value, and if such an element exists in the array, the country_name is fetched from the array withoutTo perform a lookup query. If there is no such element, then a lookup query is performed and the results are stored as a new element in the array. You also need to understand that this technique is well suited for different statements with very few key values, in this case, the less the number of unique values in the country_id column, th

Label:Trigger Triggers are a technique that is provided by many relational database systems.
