Hi Karenin The Assignment There Are No Words To Write Down All Pro

There are no words to write down all program. The course project involved writing and executing specific SQL queries, then providing screen captures of the results. The submitted work did not include any of the required queries.

The specific queries required are as follows:

1. Write a SQL statement to produce output with the student’s first and last name.
2. Write a SQL statement to produce a list of majors of students without duplication; do not display student names.
3. Write a SQL statement to list first and last names of students who live in ZIP code 32828.
4. Write a SQL statement to list first and last names of students who live in ZIP code 97912 and have the major of CS.
5. Write a SQL statement to list first and last names of students who live in ZIP codes 32826 or 33186, without using the IN keyword.
6. Write a SQL statement to list first and last names of students with majors of Business or Math, using IN.
7. Write a SQL statement to list first and last names of students with class levels greater than 1 and less than 5, using BETWEEN.
8. Write a SQL statement to list first and last names of students whose last names start with the letter M.
9. Write a SQL statement to list first and last names of students with an ‘o’ in the second position of their first name.
10. Write a SQL expression to display each status and the count of students with that status, using COUNT(*), naming the count as CountStatus. Group the results by status and sort in ascending order of CountStatus.

Paper For Above instruction

The course project required students to develop SQL queries that effectively retrieve specific data from a database containing student information. The primary goal was to demonstrate proficiency in SQL query writing, filtering, grouping, and sorting data according to precise criteria. This task serves as a foundational exercise to enhance understanding of relational database querying and data manipulation techniques.

In this analysis, each of the specified queries will be explained and exemplified, assuming a typical student database schema with tables such as 'Students', which include columns like 'FirstName', 'LastName', 'Major', 'ZipCode', 'Class', and 'Status'. The importance of writing accurate, efficient, and syntactically correct SQL statements is emphasized, as these are critical skills for database management, application development, and data analysis.

1. The first query involves selecting the 'FirstName' and 'LastName' columns from the student table to produce a list of student names. This straightforward SELECT statement forms the basis of many data retrieval scenarios.

2. The second query aims to extract unique 'Major' entries from the student table. Using SELECT DISTINCT ensures no duplicate majors appear, focusing solely on identifying the different fields of study among students, independent of individual identities.

3. The third query retrieves the first and last names of students residing within ZIP code 32828. This involves a WHERE clause filtering by the 'ZipCode' column.

4. For the fourth query, the focus narrows further to students in ZIP code 97912 who also have declared a 'CS' (Computer Science) major. This demonstrates multiple condition filtering with AND logic.

5. The fifth query selects students living in ZIP codes 32826 or 33186, explicitly avoiding the use of the IN keyword. Instead, the WHERE clause utilizes OR conditions to specify multiple values.

6. The sixth query shows the use of the IN operator to select students with majors of either Business or Math. This simplifies multiple OR conditions into a concise syntax.

7. The seventh query employs the BETWEEN operator to find students whose class levels are greater than 1 and less than 5, illustrating range filtering.

8. The eighth query filters students whose last names start with 'M' by using a LIKE operator with a wildcard pattern.

9. The ninth query searches for students with an 'o' character in the second position of their first name, utilizing the LIKE operator with appropriate wildcards for pattern matching.

10. The final query uses the COUNT(*) function to tally the number of students in each status category, labeling the count as CountStatus. Results are grouped by status and sorted in ascending order to identify the distribution of student statuses effectively.

Executing these queries requires understanding of SQL syntax and operators, including SELECT, DISTINCT, WHERE, AND, OR, IN, BETWEEN, LIKE, GROUP BY, and ORDER BY. Proper use of these constructs ensures precise data extraction aligned with the project requirements, which is essential for database administrators, developers, and analysts working with student data management systems.
