i have mysql table mytable
4 columns id
,name
,version
, date
. everyday data , data changes when install new version of our products.
i analyze change in version
numbers on time, analyze when , how many customers installing new version.
for example,
insert mytable (id,name,version,date) values (1, 'abc','1.0','07/21/2016'); insert mytable (id,name,version,date) values (1, 'abc','1.0','07/22/2016'); insert mytable (id,name,version,date) values (1, 'abc','1.1','07/23/2016');
in case, because of change in version 1.0 1.1
capture name, id, date
of 07/23/2016
.
here question: how implement in mysql?
to implement change data capture? i'm new , couldn't find tutorials well.
i can think of creating
trigger
captures change. involves performance overhead.or
select
work here?
any better solns?
i can bear performance! upon insert, how compare values capture change? or how track these changes?
trigger best solution here. there solution can schedule script run on every minutes or every 5 minutes , capture data change.
