Two tables are created: Horse with columns: ID - integer, primary key RegisteredName - variable-length string Student with columns: ID - integer, primary key FirstName - variable-length string LastName - variable-length string Create the LessonSchedule table with columns: HorseID - integer with range 0 to 65 thousand, not NULL, partial primary key, foreign key references Horse(ID) StudentID - integer with range 0 to 65 thousand, foreign key references Student(ID) LessonDateTime - date/time, not NULL, partial primary key If a row is deleted from Horse, the rows with the same horse ID should be deleted from LessonSchedule automatically. If a row is deleted from Student, the same student IDs should be set to NULL in LessonSchedule automatically
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.
12.3 LAB - Create LessonSchedule table with FK constraints
Two tables are created:
-
Horse with columns:
- ID - integer, primary key
- RegisteredName - variable-length string
-
Student with columns:
- ID - integer, primary key
- FirstName - variable-length string
- LastName - variable-length string
Create the LessonSchedule table with columns:
- HorseID - integer with range 0 to 65 thousand, not NULL, partial primary key, foreign key references Horse(ID)
- StudentID - integer with range 0 to 65 thousand, foreign key references Student(ID)
- LessonDateTime - date/time, not NULL, partial primary key
If a row is deleted from Horse, the rows with the same horse ID should be deleted from LessonSchedule automatically.
If a row is deleted from Student, the same student IDs should be set to NULL in LessonSchedule automatically.
