Question

create table ApplicationTracker_dup1
select transactionid,
       count(case when attribute = 'Secci_Page_Arrival_Time' and value is not null then transactionid end)as secci_visits,
       count(case when attribute = 'esign_arrival_time' and value is not null then transactionid end)as esig_visits 
from ApplicationTracker_dup 
where create_dtm < '2013-08-13' 
group by 1;

当我运行此代码时，遇到

ERROR 1292（22007）：截断错误的INTEGER值：'E031CF1DE8F7'“

并且没有创建表。有人可以帮助我吗？

Answer 1

很遗憾，您没有发布ApplicationTracker_dup表定义脚本，因此我建议尝试使用select子句中的attribute列或使用create_dtm列进行强制转换：

cast(attribute as char)

或

cast(create_dtm as char)

Answer 2

你应该在 count func中使用int或NULL，而不是char和其他类型所以，这段代码应该没有警告：

create table ApplicationTracker_dup1
select transactionid,
       count(if(attribute = 'Secci_Page_Arrival_Time' and value is not null,1,NULL)) as secci_visits,
       count(if(attribute = 'esign_arrival_time' and value is not null,1,NULL)) as esig_visits 
from ApplicationTracker_dup 
where create_dtm < '2013-08-13' 
group by 1;

SQL“截断的INTEGER值不正确”错误
