Question

Build the Students Table that is shown in the picture using python SQL

hint:

The SQL command to build the table is

create table student( SID int primary key not null, Name varchar(20), GPA char(3), Major varchar(25))

### Building the Students Table

This guide will help you build the Students Table as shown below. Follow the steps to understand the data structure and SQL commands used.

#### Students Table
The table contains the following fields:
- SID (Student ID)
- Name
- GPA (Grade Point Average)
- Major

| SID | Name   | GPA | Major               |
|-----|--------|-----|---------------------|
| 1   | Mike   | 3.4 | Accounting          |
| 2   | Mary   | 4.0 | Information Systems |
| 3   | William| 2.3 | Finance             |
| 4   | Joan   | 4.0 | Marketing           |

**Hint:** The SQL command to build the table is provided below.

```sql
create table student(
  SID int primary key not null, 
  Name varchar(20), 
  GPA char(3), 
  Major varchar(25)
);
```

Explanation:
- `SID int primary key not null`: This specifies that the SID column must contain integer values, cannot be null, and will be used as the primary key.
- `Name varchar(20)`: This defines the Name column to store character data with a maximum length of 20 characters.
- `GPA char(3)`: This specifies the GPA column to store a character data type with a fixed length of 3 characters, suitable for GPAs (e.g., 4.0).
- `Major varchar(25)`: This defines the Major column to store character data with a maximum length of 25 characters, which is enough to accommodate different major names.
