• Set New Values: Within the SET clause, outline the new values for each column that requires modification. For instance, if you want to update column1 with value1 and column2 with value2, you include these assignments here. Add more columns and values as necessary.
• Specify Conditions: The WHERE clause comes into play to set conditions for the records to be updated. It’s crucial to define these conditions accurately; otherwise, all records in the table will be updated.
