问题：

clickhouse查询语句抛出一下异常： e.displayText() = DB::Exception: Syntax error (Multi-statements are not allowed): 具体堆栈如下：

### The error may involve defaultParameterMap
### The error occurred while setting parameters
### SQL: SELECT count(raba.id) FROM aabbccd.test_all raba where raba.partnerCode = 'demo';
### Cause: ru.yandex.clickhouse.except.ClickHouseException: ClickHouse exception, code: 62, host: 10.58.10.10, port: 8123; Code: 62, e.displayText() = DB::Exception: Syntax error (Multi-statements are not allowed): failed at position 102 (end of query) (line 1, col 102): ;
FORMAT TabSeparatedWithNamesAndTypes.  (version 21.5.6.6 (official build))

解决方案：

去掉sql后面的分号;字符。

很神奇。
