我正在使用mybatis来更新mysql数据库，但是当我运行我的测试程序时，我发现了 BadSqlGrammarException ，我不知道如何解决它。有人可以看看它并给我一些有用的建议吗？
以下是我的问题详情：
<update id="updateTestcaseNodeBatch" parameterType="List">
<foreach collection="list" item="nodeVO" separator=";">
UPDATE testcase_node
<set>
name=#{nodeVO.name},
version=#{nodeVO.version},
description=#{nodeVO.description},
last_modify_user=#{nodeVO.createUser},
last_modify_time=#{nodeVO.createTime}
</set>
<where>
object_id=#{nodeVO.objectId} AND root_id=#{nodeVO.rootId}
</where>
</foreach>
</update>
@Override
public int[] parseImportTestcaseData(List<TestcaseNodeVO> nodeList) {
int[] result=new int[3];
int ignoreNum=0;
List<TestcaseNodeVO> addList=new ArrayList<TestcaseNodeVO>();
List<TestcaseNodeVO> updateList=new ArrayList<TestcaseNodeVO>();
TestcaseNodeModel tempNode=null;
for(TestcaseNodeVO nodeVO:nodeList){
tempNode=testcaseNodeDao.queryNodeByObjectId(nodeVO.getObjectId(),nodeVO.getRootId());
if(tempNode==null){
addList.add(nodeVO);
}else{
if(tempNode.getVersion()<nodeVO.getVersion()){
updateList.add(nodeVO);
}else{
ignoreNum++;
}
}
tempNode=null;
}
if(addList.size()>0){
testcaseNodeDao.addTestcaseNodeBatch(addList);
}
if(updateList.size()>0){
testcaseNodeDao.updateTestcaseNodeBatch(updateList);
}
result[0]=addList.size();
result[1]=updateList.size();
result[2]=ignoreNum;
return result;
}

通过sql异常stacktrace，我发现它是由于我的语法错误，因此我尝试了我的Mybatis XML块如下所示（删除seperator属性并在每个sql的末尾添加一个分号< / em>），但仍然失败：
<update id="updateTestcaseNodeBatch" parameterType="List">
<foreach collection="list" item="nodeVO">
UPDATE testcase_node
<set>
name=#{nodeVO.name},
version=#{nodeVO.version},
description=#{nodeVO.description},
last_modify_user=#{nodeVO.createUser},
last_modify_time=#{nodeVO.createTime}
</set>
<where>
object_id=#{nodeVO.objectId} AND root_id=#{nodeVO.rootId};
</where>
</foreach>
</update>
我已经尝试了很多方法但仍无法找到解决方案，有人可以帮我解决吗？提前感谢！
答案 0 :(得分：2)
我认为问题是mysql默认不支持执行多个sqls，但在你的情况下批量更新需要那个。所以你必须添加 参数“ allowMultiQueries ”启用它。 如下： jdbc：mysql：//10.255.10.105：3306 / PB_MANAGEMENT_PLATFORM？allowMultiQueries = true
答案 1 :(得分：0)
当我在mybatis上使用多次更新时发生了同样的错误，然后我将参数allowMultiQueries=true附加到JDBC的URL，现在它运行良好。
并且item和index在一起吗？
<foreach collection="list" item="nodeVO" index="index" separator=";">
但是当我更新对象列表时，多次更新的结果为1，并且mysql中更改的数据数等于该列表的大小。这让我很困惑。
答案 2 :(得分：-1)
看看这个参考是否有帮助？
Multiple queries executed in java in single statement
如果你使用Spring-Batch，这可能会派上用场
<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg index="0" ref="sqlSessionFactory" />
<constructor-arg index="1" value="BATCH" />
</bean>
