Concept explainers

Intermediate SQL Concepts

A query is a request for data or information from one or more database tables. This information could be presented in the form of pictorials, graphs, or complicated findings which helps in easy interpretation. Structured Query Language (SQL) is the most widely used programming language for retrieving and organizing data from relational databases. Collection of tables with rows and columns is referred to as a database. SQL is the language of databases. It makes it easier to extract specific data from databases, which can then be used for analysis.

The table STUDENT has the attributes STUDENT_ID, NAME, S_ID, and ADDR. The table SCHOOL has the attributes SCHOOL_ID, NAME, and STATE_CODE. Assume that there is a 1:N relation between SCHOOL and STUDENT where the common attributes are S_ID, and SCHOOL_ID. Which of the following creates a table that shows the STUDENT attributes and the corresponding SCHOOL attributes? a. SELECT * FROM STUDENT JOIN SCHOOL USING(SCHOOL_ID) b. SELECT * FROM STUDENT JOIN SCHOOL USING(S_ID) c. SELECT * FROM STUDENT NATURAL JOIN SCHOOL ON S_ID AND SCHOOL.SCHOOL_ID d. SELECT * FROM STUDENT JOIN SCHOOL ON STUDENT.S_ID = SCHOOL.SCHOOL_ID

True or False below: Given two relations named A and B, if we q-JOIN A and B, the maximum number of attributes in the result relation could be (the number of attributes of A) times(*) the number of attributes of B). * in an SQL SELECT statement means “all the tuples”. In relational algebra, Cartesian Product (X) can be implemented using the q-JOIN operator. Cartesian Product ISA q-JOIN where q-condition always evaluates to true. SQL is based on Predicate Calculus. A query in SQL always specifies what should be included in the query result.
