Question
The employee table contains information about employees. One of your employees got married, so herlast name changed. What command should you use to reflect this change in the table?
Solution
To reflect this change in the table, you would use the SQL UPDATE command. Here is a step by step guide:
-
First, you need to identify the specific row that needs to be updated. This is typically done using the employee's unique ID. Let's assume the employee's ID is 123 and her new last name is "Smith".
-
Next, you would use the UPDATE command to change the last name. The general syntax for the UPDATE command is:
UPDATE table_name SET column1 = value1, column2 = value2...., columnN = valueN WHERE [condition]; -
In this case, you would write:
UPDATE employee SET last_name = 'Smith' WHERE id = 123;
This command tells the SQL database to update the 'employee' table by setting the 'last_name' column to 'Smith' for the row where the 'id' is 123.
Remember to replace 'Smith' and '123' with the actual new last name and the actual ID of the employee.
