Resolving ID Value Issues in Oracle PL/SQL: A Trigger Solution
Oracle PL/SQL: Inserting ID from One Table into Another
Understanding the Issue The problem at hand is to create a trigger in Oracle PL/SQL that inserts values from one table (hotel) into another table (restaurant). The hotel table has a primary key column named Hotel_ID, which is automatically generated using a sequence. When data is inserted into the hotel table, the value of Hotel_ID is not being properly populated in the restaurant table.
