One common task you can perform using SQL at work is data retrieval. For instance, a marketing analyst might use SQL to extract customer data from a database to analyze customer behavior and preferences. This can help in creating targeted marketing campaigns.

Another common task is data modification. For example, a database administrator might use SQL to update records in a customer database to reflect changes in customer information, such as updating addresses or phone numbers.

Lastly, SQL can be used for data insertion. A human resources employee might use SQL to add new employee records to the company's database, ensuring that all relevant information is stored and easily accessible.
