mysql - SQL“截断不正确的整数值”错误

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;

当我运行这段代码时，我遇到

错误 1292 (22007)：截断不正确的整数值：'E031CF1DE8F7'"

并且没有创建表。有人可以在这里帮助我吗？

Answer 1

您应该在count func中使用 int 或 NULL ，而不是 char 和其他类型因此，此代码应该可以在没有警告的情况下工作：

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;

Answer 2

不幸的是，您没有发布ApplicationTracker_dup表定义脚本，所以我建议尝试attribute在 select 子句中的create_dtm列或这样的列中使用 cast：

cast(attribute as char)

或者

cast(create_dtm as char)
