I'm trying to edit column DEGREE_TYPE_MAJOR to DEGREE_TYPE and add a column MAJOR in Snowflake. How can I do this?

 

### Database Table Creation and Modification #### SQL Script The SQL script demonstrates the creation and modification of a table named `TUITIONASSIST` in a database. Below is the explanation of each SQL command: 1. **Table Creation** ```sql CREATE TABLE TUITIONASSIST( Employee_ID INT PRIMARY KEY, Employee_Name VARCHAR(40), Application_Status VARCHAR(30), Applied_Date DATE, Total_Paid_Amount FLOAT, Degree_Type VARCHAR(50), Major VARCHAR(50), School_Name VARCHAR(50) ); ``` - **Employee_ID**: An integer serving as the primary key for uniquely identifying each entry. - **Employee_Name**: A variable character field with a maximum length of 40 characters. - **Application_Status**: A variable character field, up to 30 characters, indicating the application's status. - **Applied_Date**: A date field showing when the application was submitted. - **Total_Paid_Amount**: A floating-point number representing the total amount paid. - **Degree_Type**, **Major**, **School_Name**: All are variable character fields with a 50 character limit, specifying the degree type, major, and school name respectively. 2. **Column Renaming** ```sql ALTER TABLE TUITIONASSIST RENAME COLUMN degree_type_major TO degree_type; ``` - This command renames the column `degree_type_major` to `degree_type`. 3. **Data Selection** ```sql SELECT * FROM "HRPA_TEST"."DBO"."TUITIONASSIST"; ``` - This query retrieves all records from the `TUITIONASSIST` table, which is under the `"HRPA_TEST"."DBO"` schema. ### Data Preview There is a section for data preview, labeled `Table: HRPA_TEST.DBO.TUITIONASSIST`, indicating where you would see data entries once they exist. The listed columns include: - **EMPLOYEE_ID** - **EMPLOYEE_NAME** - **APPLICATION_STATUS** - **APPLIED_DATE** - **TOTAL_PAID_AMOUNT** - **DEGREE_TYPE_MAJOR** - **SCHOOL_NAME** Currently, the data preview displays 0 rows, indicating that there are no entries in the table at the moment. This setup allows for managing and querying a database designed to handle tuition assistance information for employees.
