Hi all. I'm having trouble converting some (working) inline parameters
to the equivalent parameter map.
This works just fine:
SELECT substr(administrative_code, 1, 3) as org
FROM administrative_code a, employeeMaster e
WHERE rtrim(a.administrative_code) = rtrim(e.org)
AND a.administrative_code like #org#
GROUP BY substr(administrative_code, 1, 3)
This does not:
SELECT
Hi
I was wondering if Map/Reduce could be used for replicate the RRD
derive feature. i.e:
I have a simple database structure for tracking a users time on a
website. The session_time entry is accumulative. i.e The first
session_time entry when you search and sort by session_id and
session_time with always be 0 last entry will always be the total
session time
This is how the data is saved
http://en.wikipedia.org/wiki/Internet_Movie_Database#Ranking
reduce: function (obj, prev) { prev.sum += obj.value; prev.count++;}
finalize: function (out) { out.w=(out.sum + C * m) / (out.count +
m); }
Now, how can I pass in C and m as parameters? Â ( I am using PHP and
the command() method. And, C is constantly changing based on w, isn't
it? I am getting a confused a little :/
Thanks
Hi,
I all, I have been involved to convert old daos to sql mapper xml. One of
the problem I having is.My old daos uses same field in more than one
params. I have to keep adding these fields in to my VO to pass in to the sql
mappers. For example
Object[] params = new Object[4];
params[0] = argStartTimeStamp;
params[1] = argEndTimeStamp;
params[2]
SELECT
Hi-
I'm currently trying to convert already existing JSON (not generated by avro) to avro and
am wondering if there is some generic way to do this (maybe an avro schema that matches arbitrary
JSON)? Or are there any helpers that would allow me to map a parsed JSON onto an enxisting
avro schema, given I could create one that semantically maches the JSON data I have?
Sorry if this sounds a bit vague
Hi,
I have a column in my schemaRDD that is a map but I'm unable to convert it
to a map.. I've tried converting it to a Tuple2[String,String]:
val converted = jsonFiles.map(line=> {
line(10).asInstanceOf[Tuple2[String,String]]})
but I get ClassCastException:
14/11/23 11:51:30 WARN scheduler.TaskSetManager: Lost task 0.0 in stage 1.0
(TID 2, localhost): java.lang.ClassCastException:
org.apache
Maybe it is late and my brain just isn't working anymore, but I am
trying to convert a
Map[Long, Future[SomeType]] => Future[Map[Long,SomeType]]
Is there an elegant way to do this? Right now I have a method like
this
def doit[T]( mp :Map[Long,Future[T]]) = Future {
  mp.map{ case ( key, fut) => ( key, fut.get ) }
}
That doesn't feel right. Any thoughts?
Thanks,
Andy
What is the data type in Ebean to map a DateTime column in MySQL? I think the following code will get only date part, no time part:
@Formats.DateTime(pattern="yyyy-MM-dd")
�public Date create_datetime = new Date();
Camel Users,
Is there a way to convert the body to a Map of a Map without needing to
write a custom converter? The body comes from a CSV file with comma as the
delimitter. The CSV contains 5 fields and out of that five fields, I want
to pick 3 of them and create the Map of Map structure. Any suggestions?

Hi,
I'm pretty new to SOLR and I'd like to ask your opinion on the best practice for converting
XML results you get from SOLR into something that is better fit to display on a webpage. I'm
looking for performance and relatively small footprint, perhaps ability to paginate thru the
result set and display/process N results at a time. Any ideas? Any tutorials you can point
me to? Thanks!
