mysql-错误1064（42000）：....在'（PARTITION BY t1.DIGEST）附近

Question

我试图在ubuntu / mysql中执行此查询：

SELECT t1.SCHEMA_NAME, CONCAT(ROUND(BUCKET_QUANTILE*100,2),"% under ",
               BUCKET_TIMER_HIGH/1000000000," milliseconds") fact, 
               LEFT(QUERY_SAMPLE_TEXT,64) as QUERY_SAMPLE, t1.DIGEST, 
               COUNT(t1.DIGEST) 
               OVER(PARTITION BY t1.DIGEST) as TOT 
              FROM events_statements_histogram_by_digest t1 
              JOIN events_statements_summary_by_digest t2 
                ON t2.DIGEST = t1.DIGEST 
             WHERE COUNT_BUCKET >1 
             ORDER BY t1.DIGEST, BUCKET_TIMER_HIGH DESC 
             LIMIT 10\G

和结果：

ERROR 1064 (42000): 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 
'(PARTITION BY t1.DIGEST) as TOT FROM events_statements_histogram_by_digest t1 JO' 
at line 1

我还没有找到更正该查询的方法。请帮忙。谢谢。
