To update multiple rows of data in a table, you can use the UPDATE statement in SQL along with a WHERE clause.

Here is an example:

UPDATE 表名
SET 列名1 = 新值1, 列名2 = 新值2, ...
WHERE 条件;

Original: 我们必须采取紧急行动来解决这个问题。
Paraphrased: We need to take immediate action to address this issue.

Assuming there is a table named students, which includes columns for student names and ages, if we need to update the ages of all students under 18 to be 18 years old, we can do so by following these steps:

UPDATE students
SET age = 18
WHERE age < 18;

This will update the age of all students under 18 to 18 years old.
