该语法将数据表中符合 WHERE 条件的记录中的 column1 的值更新为 new_value1，column2 的值更新为 new_value2
，以此类推。如果省略 WHERE 条件，则会将表中所有记录的 colum]]></description><category></category></item><item><title><![CDATA[MySQL增加和查询]]></title><link>https://blog.youkuaiyun.com/fuchang1/article/details/121333773</link><guid>https://blog.youkuaiyun.com/fuchang1/article/details/121333773</guid><author>fuchang1</author><pubDate>Mon, 15 Nov 2021 14:16:26 +0800</pubDate><description><![CDATA[MySQL mysql_query 函数执行SQL语句

INSERT INTO 语法用于向数据表中添加数据记录。
语法：

INSERT INTO tb_name (column1, column2,...) VALUES (value1, value2,...)
