Oracle和MySQL数据库的批量update在mybatis中配置不太一样：
oracle数据库：
<code style=""><<span style="">update</span> id=<span style="">"batchUpdate"</span> parameterType=<span style="">"java.util.List"</span>> <<span style="">foreach</span> collection=<span style="">"list"</span> item=<span style="">"item"</span> index=<span style="">"index"</span> <span style="">open</span>=<span style="">"begin"</span> <span style="">close</span>=<span style="">"end;"</span> separator=<span style="">";"</span>> <span style="">update</span> test <<span style="">set</span>> test=${item.test}+<span style="">1</span> </<span style="">set</span>> where id = ${item.id} </<span style="">foreach</span>> </<span style="">update</span>></code> mysql数据库：
mysql数据库采用一下写法即可执行，但是数据库连接必须配置：&allowMultiQueries=true
例如：jdbc:mysql://192.168.1.236:3306/test?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true
<code style=""><<span style="">update</span> id=<span style="">"batchUpdate"</span> parameterType=<span style="">"java.util.List"</span>> <<span style="">foreach</span> collection=<span style="">"list"</span> item=<span style="">"item"</span> index=<span style="">"index"</span> <span style="">open</span>=<span style="">""</span> <span style="">close</span>=<span style="">""</span> separator=<span style="">";"</span>> <span style="">update</span> test <<span style="">set</span>> test=${item.test}+<span style="">1</span> </<span style="">set</span>> where id = ${item.id} </<span style="">foreach</span>> </<span style="">update</span>></code> 以上所述是小编给大家介绍的mybatis执行批量更新batch update 的方法（oracle,mysql两种），希望对大家有所帮助，如果大家有任何疑问请给我留言，小编会及时回复大家的。在此也非常感谢大家对武林网网站的支持！
