MyBatis Batch Update Exception - batch-file

Question

I am using mybatis to update mysql database,but when I run my test program I found a BadSqlGrammarException and I do not know how to solve it.Could anyone have a look at it and give me some useful advices?
Below is my issue detail:
Mybatis SQL file:
<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>
Java method block:
#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;
}
* The last is my exception stacktrace:

Through the sql exception stacktrace,I could found it was due to my wrong syntax,and thus I have tried to my Mybatis XML block as below(remove seperator property and add a semicolon at the end of each sql),but still failed:
<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>
I have tried many ways to do it but still can not find a solution for it,could anyone help me to solve it?Thanks in advance!

Answer 1

I think the problem is mysql doesn't support executing multi sqls by default, but in your case the batch update need that.So you have to add
parameter "allowMultiQueries" to enable that.
like below:
jdbc:mysql://10.255.10.105:3306/PB_MANAGEMENT_PLATFORM?allowMultiQueries=true

Answer 2

The same error occurred while I used the multiple update on mybatis, then I appended the parameter allowMultiQueries=true to the URL of JDBC, and it works well now.
and are the item and index together?
<foreach collection="list" item="nodeVO" index="index" separator=";">
but the result of multiple update is 1 when I update a list of object , and the number of data changed in mysql equals the size of that list . It makes me confused .

Answer 3

See if this reference help?
Multiple queries executed in java in single statement
And if you are using Spring-Batch, this might comes in handy
<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg index="0" ref="sqlSessionFactory" />
<constructor-arg index="1" value="BATCH" />
</bean>
