Question
Select tuples from the CUSTOMER relation in which SALES-PERS-NO=l 824. Project the CUST-NOand CITY over that result.
Solution
To answer your question, you would use SQL (Structured Query Language), which is used to manage and manipulate databases. Here is how you would do it:
SELECT CUST-NO, CITY
FROM CUSTOMER
WHERE SALES-PERS-NO = 1824;
This SQL query does the following:
SELECT CUST-NO, CITY: This part selects the data from the columns named 'CUST-NO' and 'CITY'.FROM CUSTOMER: This part specifies from which table in the database to select the data. In this case, it's from the table named 'CUSTOMER'.WHERE SALES-PERS-NO = 1824: This is the condition for selecting the data. It selects only the rows where the 'SALES-PERS-NO' is equal to 1824.
