bug简述：sql由SQLServer转换成MySQL后，navicat下可以执行，项目中却报错。
报错如下：
1-1
### Error querying database. Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Create TEMPORARY TABLE temp_table3
select * from (
select * from VIEW_UserMe' at line 2
### The error may exist in XX/XXX/XXXX/XXXXX/mapper/XXXXXMapper.xml
### The error may involve defaultParameterMap
### The error occurred while setting parameters
### SQL: Drop TEMPORARY TABLE IF exists temp_table3; Create TEMPORARY TABLE temp_table3 select * from ( select * from VIEW_UserMeter where supplierID =1 and SampleTime between date_sub(NOW(),interval 1 day) and date_add(NOW(),interval 1 day) ) as a; select * from (SELECT ROW_NUMBER() OVER ( ORDER BY sampleTime ) AS rownumber , building,entrance,doorplate,village,userName,remark1,remark2,meterId,meterSize,total,pressure,flowRate,valveStatus,status,updateTime,timeInp,vol,operate_ValveStatus,sampleTime,t1Inp FROM temp_table3 ) cc WHERE cc.rownumber > 0 limit 50; Drop TEMPORARY TABLE IF exists temp_table3;
### Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Create TEMPORARY TABLE temp_table3
select * from (
select * from VIEW_UserMe' at line 2
; bad SQL grammar []; nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Create TEMPORARY TABLE temp_table3

将sql粘出执行，如下图，可成功执行，查询出结果，排除转换出错的可能：
1-2
回过头查看控制台error:
### The error may involve defaultParameterMap
### The error occurred while setting parameters
考虑到是不是MyBatis不支持在XML配置的SQL中带有分号“;”。
经查询，开启了allowMultiQueries=true，MyBatis即可支持批量处理sql.
如下图：
1-3
重新启动项目，可成功执行，问题解决。
