How can I update multiple data records in one go?

To update multiple pieces of data at once, you can utilize the CASE syntax in the UPDATE statement.

Here is an example: Suppose there is a table called table_name, with a column named column_name, and we want to simultaneously update multiple values to different new values.

UPDATE table_name
SET column_name = CASE
    WHEN condition1 THEN new_value1
    WHEN condition2 THEN new_value2
    WHEN condition3 THEN new_value3
    ...
    ELSE column_name
END;

In the example above, conditions such as condition1, condition2, condition3 represent the conditions of the data to be modified. If a condition is true, the corresponding new_value will be assigned to the corresponding row.

If no conditions are true, specify a default value using the ELSE statement, meaning no changes will be made to that line.

Please modify the above example to fit your specific needs and data conditions.
