A database interrogation is a major benefit of the database management approach, where end users can query (ask) the database for information. The Structured Query Language (SQL) is an international standard query language found in many DBMS packages. The basic form of a SQL query is: SELECT . . . FROM . . . WHERE . . .
For example, if we have the following STUDENTS table:
| STUDENT_ID | STUDENT_NAME | COURSE_ID | STUDENT_GPA | COLLEGE_CODE |
| 140064001 | Ahmad Nasser | IT101 | 3.5 | CHS |
| 140064002 | Sarah Abdullah | IT343 | 2.75 | CCI |
| 140064003 | Sultan Mohamed | IT242 | 3.15 | CCI |
| 140064004 | Basmah Khaled | IT446 | 3.90 | CCI |
| 140064005 | Bader Ali | IT101 | 2.90 | CHI |
| 140064006 | Fahad Mutlaq | IT448 | 1.95 | CCI |
| 140064007 | Salman Abdulaziz | IT242 | 2.90 | CCI |
The following SQL query is used to retrieve STUDENT_NAME and COURSE_ID for all students who have GPA = 2.90
SELECT [STUDENT_NAME], [COURSE_ID]
FROM [STUDENTS]
WHERE [STUDENT_GPA] = 2.90
And the result of the above query is:
| STUDENT_NAME | COURSE_ID |
| Bader Ali | IT101 |
| Salman Abdulaziz | IT242 |
Based on the above STUDENTS table, answer the following questions:
Write an SQL query to retrieve STUDENT_ID and STUDENT_GPA for all CCI students who study the course has the code IT101.
What is the result of the following query?
SELECT [STUDENT_ID], [COURSE_ID], [COLLEGE_CODE]
FROM [STUDENTS]
WHERE [COURSE_ID] = IT242 OR [STUDENT_GPA] > 3.00
