Explanation:

Symbol for Viewing Every Column in a Table:
- In SQL, the asterisk symbol (*) is used to represent all columns in a table.
- When you use the asterisk symbol in the SELECT statement, it retrieves all columns from the specified table.

Example:
- For example, if you have a table called "employees" with columns such as "id", "name", "department", and "salary", you can use the following query to select all columns:
sql
SELECT * FROM employees;
- This query will return all columns for every row in the "employees" table.

Benefits of Using the Asterisk Symbol:
- Using the asterisk symbol (*) is convenient when you want to retrieve all columns from a table without specifying each column individually.
- It saves time and effort, especially when dealing with tables that have a large number of columns.

Limitations:
- While using the asterisk symbol is convenient, it is important to note that it may not be the most efficient way to retrieve data, especially in large databases.
- Retrieving unnecessary columns can impact the performance of your queries and increase network traffic.

Conclusion:
- In summary, the asterisk symbol (*) is used to view every column of a table in SQL queries. It provides a quick and easy way to retrieve all columns from a table, but it is important to consider the potential drawbacks in terms of performance and efficiency.
