oracle和mysql数据库的批量update在mybatis中配置不太一样:

oracle数据库:

<update id="batchUpdate"  parameterType="java.util.List">	 	   <foreach collection="list" item="item" index="index" open="begin" close="end;" separator=";">				update test 				<set>				  test=${item.test}+1				</set>				where id = ${item.id}	   </foreach>		     </update>
Copy after login

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

<update id="batchUpdate"  parameterType="java.util.List">	 	      <foreach collection="list" item="item" index="index" open="" close="" separator=";">				update test 				<set>				  test=${item.test}+1				</set>				where id = ${item.id}		 </foreach>		     </update>
Copy after login
