The option for referential integrity between the Owner table and the Pet table is restrict and an attempt is made to update the row for owner 005 (OwnerNum = 005) in the Owner table to become 500 (OwnerNum = 500). What is the result? (Use only the data in the question. Do not assume other data exists if it is not present in the tables below.) The primary keys are underlined. These are the OwnerNum column in the Owner table and the PetNumber in the Pet table. The foreign key is italicized. This is the OwnerNum column in the Pet table.

That row (OwnerNum = 005) in the Owner table will be updated to have a OwnerNum of 500 and so will the related row(s) in the Pet table that refer to it Nothing will be updated in the Owner table and nothing will be updated in the Pet table. Just that row (OwnerNum = 005) in the Owner table will be updated. Its OwnerNum will change from 005 to 500. There are no related rows in the Pet table.
SQL
SQL stands for Structured Query Language, is a form of communication that uses queries structured in a specific format to store, manage & retrieve data from a relational database.
Queries
A query is a type of computer programming language that is used to retrieve data from a database. Databases are useful in a variety of ways. They enable the retrieval of records or parts of records, as well as the performance of various calculations prior to displaying the results. A search query is one type of query that many people perform several times per day. A search query is executed every time you use a search engine to find something. When you press the Enter key, the keywords are sent to the search engine, where they are processed by an algorithm that retrieves related results from the search index. Your query's results are displayed on a search engine results page, or SER.
