Oracle和MySQL數據庫的批量update在mybatis中配置不太一樣：
oracle數據庫：
<code class="hljs tcl" style=""><<span class="hljs-keyword" style="">update</span> id=<span class="hljs-string" style="">"batchUpdate"</span> parameterType=<span class="hljs-string" style="">"java.util.List"</span>> <<span class="hljs-keyword" style="">foreach</span> collection=<span class="hljs-string" style="">"list"</span> item=<span class="hljs-string" style="">"item"</span> index=<span class="hljs-string" style="">"index"</span> <span class="hljs-keyword" style="">open</span>=<span class="hljs-string" style="">"begin"</span> <span class="hljs-keyword" style="">close</span>=<span class="hljs-string" style="">"end;"</span> separator=<span class="hljs-string" style="">";"</span>> <span class="hljs-keyword" style="">update</span> test <<span class="hljs-keyword" style="">set</span>> test=${item.test}+<span class="hljs-number" style="">1</span> </<span class="hljs-keyword" style="">set</span>> where id = ${item.id} </<span class="hljs-keyword" style="">foreach</span>> </<span class="hljs-keyword" style="">update</span>></code> mysql數據庫：
mysql數據庫采用一下寫法即可執行，但是數據庫連接必須配置：&allowMultiQueries=true
例如：jdbc:mysql://192.168.1.236:3306/test?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true
<code class="hljs tcl" style=""><<span class="hljs-keyword" style="">update</span> id=<span class="hljs-string" style="">"batchUpdate"</span> parameterType=<span class="hljs-string" style="">"java.util.List"</span>> <<span class="hljs-keyword" style="">foreach</span> collection=<span class="hljs-string" style="">"list"</span> item=<span class="hljs-string" style="">"item"</span> index=<span class="hljs-string" style="">"index"</span> <span class="hljs-keyword" style="">open</span>=<span class="hljs-string" style="">""</span> <span class="hljs-keyword" style="">close</span>=<span class="hljs-string" style="">""</span> separator=<span class="hljs-string" style="">";"</span>> <span class="hljs-keyword" style="">update</span> test <<span class="hljs-keyword" style="">set</span>> test=${item.test}+<span class="hljs-number" style="">1</span> </<span class="hljs-keyword" style="">set</span>> where id = ${item.id} </<span class="hljs-keyword" style="">foreach</span>> </<span class="hljs-keyword" style="">update</span>></code> 以上所述是小編給大家介紹的mybatis執行批量更新batch update 的方法（oracle,mysql兩種），希望對大家有所幫助，如果大家有任何疑問請給我留言，小編會及時回復大家的。在此也非常感謝大家對武林網網站的支持！
