bug簡述：sql由SQLServer轉換成MySQL后，navicat下可以執行，項目中卻報錯。

報錯如下：

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

select * from (

select * from VIEW_UserMe' at line 2

將sql粘出執行，如下圖，可成功執行，查詢出結果，排除轉換出錯的可能：

1-2

回過頭查看控制臺error:

### The error may involve defaultParameterMap

### The error occurred while setting parameters

考慮到是不是MyBatis不支持在XML配置的SQL中帶有分號“;”。

經查詢，開啟了allowMultiQueries=true，MyBatis即可支持批量處理sql.

如下圖：

1-3

重新啟動項目，可成功執行，問題解決。
