Update Multiple SQL Fields: Quick Tutorial

In SQL, the UPDATE statement can be used to update multiple fields. When updating multiple fields, you can specify multiple fields and their corresponding new values in the SET clause. For example:

UPDATE 表名
SET 字段1 = 值1, 字段2 = 值2, 字段3 = 值3
WHERE 条件

In the statement above, “表名” refers to the name of the table to be updated, “字段1、字段2、字段3” are the fields to be updated, “值1、值2、值3” represent the corresponding new values, and “条件” indicates the condition for updating records.

For example, let’s say there is a table called students, which includes fields id, name, and age. Now, to change the name and age of the student with id 1 to “Alice” and 20, you can use the following SQL statement:

UPDATE students
SET name = 'Alice', age = 20
WHERE id = 1

With the above SQL statement, you can update the name and age of the student with id 1 in the table.
