There are no related rows in the Pet table. Nothing will be deleted from the Owner table and nothing will be deleted from the Pet table. That row (OwnerNum 012) in the Owner table will be deleted and so will the related row(s) from the Pet table that refer to it. That row (OwnerNum 012) from the Owner table will NOT be deleted but any related row(s) in the Pet relation will be deleted.
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.
