Memcached Ibatis controller ?

[Josh Joy <jo...@gmail.com>]

Hi,

Is there a memcached ibatis controller available? A quick search on google
only turned up results for .NET

Thanks,
Josh

groupBy list always contains empty row.

[Harvey Kim <ca...@fastmail.fm>]

Java class:
-----------
class SomeClassDTO
{
  blah, blah, blah attributes ...
  List someGroupByList = null;
}


Ibatis Mapping and select statement
-----------------------------------
<resultMap id="someMap" groupBy="someId" class="SomeClassDTO">
        <result property="someId" ..../>
	<result property="someGroupByList" resultMap="someGroupByList.someGroupByListMap"/>
</resultMap>

<select id="selectSomething" resultMap="someMap" >
SELECT blah blah blah attributes, joinTable.* 
FROM someTable
LEFT JOIN joinTable
ON (joinTable.someId = 123456789)
WHERE someTable.someId = 123456789


If 123456789 does NOT exist in "joinTable", shouldn't "someGroupByList"
stay null?  It always seems to have list size of 1 even if the join
entry does not exist.  Was this by design or is there something I'm not
doing wrong.  I realize the solution is to not use groupBy and populate
the list indepedently but if there is a magic flag, I'd appreciate it.

thanks,

-Harvey

Not that I am aware of, but if you want to write one, it *should* be
fairly straightforward. Look at the existing sources for the other
cache implementations for a starting point.

Also, you can use oscache as well with ibatis, which supports a distributed
cache.

I am not aware of the usage of memcache. But googling on it tells me that it
simply stores data in memory and you hit the database only when the data
isn't available in memory cache.
Ibatis does provide you with a cache type called "MEMORY". I guess it does
something similar. You may wanna read through the documentation and see if
this is any where closer to what you need!! My Guess is you could improvise
on this for your implementation, if it doesn't completely help your cause.
