I'm trying to run a query against the ReleaseCumulativeFlowData object as follows:
((ReleaseObjectID = 12345) AND CardState="Accepted")
However, running the query results in the following error message:
OperationResultError
Could not read: could not read all instances of class
com.f4tech.slm.domain.reporting.ReleaseCumulativeFlowDataSet
Is this a bug in Rally?
WSAPI is very picky about the structure of the query. You have to include parentheses around chained query filters, so you would need something like the following:
((ReleaseObjectID = 12345) AND (CardState = "Accepted"))

I am working on SQL query, I have pre-created SOQL query, I am looking for a way to convert it to SQL query. The query is:
SELECT CronJobDetail.Name, Id, CreatedDate, State
FROM CronTrigger
WHERE CronjobDetail.JobType = 'bla bla'
AND CronJobDetail.Name LIKE '%bla bla2%'
But It does not run on terminal when I try to create monitoring script in Ruby. The error that I get:
(Got exception: INVALID_FIELD: No such relation 'CronJobDetail' on
entity 'CronTrigger'. If you are attempting to use a custom field, be
sure to append the '__c' after the custom field name. Please reference
your WSDL or the describe call for the appropriate names. in
/Users/gakdugan/.rvm/gems/ruby-1.9.3-p547/gems/restforce-2.2.0/lib/restforce/middleware/raise_error.rb:18:in
`on_complete'
Do you have any idea how can I fix it and make it run on SQL?
You are trying to access a relation without adding it to your FROM clause. Alternatively, if that's a custom field name, then do what the error message suggests you to do (add __c after the custom field name).
You probably want to do something like this:
SELECT CronJobDetail.Name, CronTrigger.Id, CronTrigger.CreatedDate, CronTrigger.State
FROM CronTrigger
INNER JOIN CronJobDetail ON CronJobDetail.id = CronTrigger.foreign_id // this you have to do yourself
WHERE CronjobDetail.JobType = 'bla bla'
AND CronJobDetail.Name LIKE '%bla bla2%'
I've not played with Ruby in a while, and was just writing a simple db query tool.
The tool connects fine and returns the correct number of results for the query (56 rows in this case), but the value returned for each element is 'nil'. Executing the query in sqlplus works fine.
I've found similar problems on StackExchange, but most of the solutions don't apply, or require using ODBC directly. Ugh.
I'm including a stripped down version of what I've written. Any ideas what I'm doing wrong?
require 'dbi'
dbh = DBI.connect('DBI:OCI8:foodb', 'user', 'password')
rs = dbh.prepare('select field_name from foo_user.cdr_fields where layout like ?')
rs.execute('phi_outage')
while rsRow = rs.fetch do
p rsRow
end
rs.finish
dbh.disconnect
The fetch method is an iterator so no need for a while loop. Try
rs.fetch do|row|
p row unless p.nil?
end
The API states that the method gets called for all remaining rows and will return nil when done.
I'm missing something simple - I do not want to access the results of this query in a view.
Here is the query:
#adm = Admin.where({:id => {"$ne" => params[:id].to_s},:email => params[:email]})
And of course when you inspect you get:
#adm is #<MongoMapper::Plugins::Querying::DecoratedPluckyQuery:0x007fb4be99acd0>
I understand (from asking the MM guys) why this is the case - they wished to delay the results of the actual query as long as possible, and only get a representation of the query object until we render (in a view!).
But what I'm trying to ascertain in my code is IF one of my params matches or doesn't match the result of my query in the controller so I can either return an error message or proceed.
Normally in a view I'm going to do:
#adm.id
To get the BSON out of this. When you try this on the Decorated Query of course it fails:
NoMethodError (undefined method `id' for #<MongoMapper::Plugins::Querying::DecoratedPluckyQuery:0x007fb4b9e9f118>)
This is because it's not actually a Ruby Object yet, it's still the query proxy.
Now I'm fundamentally missing something because I never read a "getting started with Ruby" guide - I just smashed my way in here and learned through brute-force. So, what method do I call to get the results of the Plucky Query?
The field #adm is set to a query as you've seen. So, to access the results, you'll need to trigger execution of the query. There are a variety of activation methods you can call, including all, first, and last. There's a little documentation here.
In this case, you could do something like:
adm_query = Admin.where({:id => {"$ne" => params[:id].to_s},:email => params[:email]})
#adm_user = adm_query.first
That would return you the first user and after checking for nil
if #adm_user.nil?
# do something if no results were found
end
You could also limit the query results:
adm_query = Admin.where( ... your query ...).limit(1)
If I were retrieving the data I wanted from a plain sql query, the following would suffice:
select * from stvterm where stvterm_code > TT_STUDENT.STU_GENERAL.F_Get_Current_term()
I have a grails domain set up correctly for this table, and I can run the following code successfully:
def a = SaturnStvterm.findAll("from SaturnStvterm as s where id > 201797") as JSON
a.render(response)
return false
In other words, I can hardcode in the results from the Oracle function and have the HQL run correctly, but it chokes any way that I can figure to try it with the function. I have read through some of the documentation on Hibernate about using procs and functions, but I'm having trouble making much sense of it. Can anyone give me a hint as to the proper way to handle this?
Also, since I think it is probably relevant, there aren't any synonyms in place that would allow the function to be called without qualifying it as schema.package.function(). I'm sure that'll make things more difficult. This is all for Grails 1.3.7, though I could use a later version if needed.
To call a function in HQL, the SQL dialect must be aware of it. You can add your function at runtime in BootStrap.groovy like this:
import org.hibernate.dialect.function.SQLFunctionTemplate
import org.hibernate.Hibernate
def dialect = applicationContext.sessionFactory.dialect
def getCurrentTerm = new SQLFunctionTemplate(Hibernate.INTEGER, "TT_STUDENT.STU_GENERAL.F_Get_Current_term()")
dialect.registerFunction('F_Get_Current_term', getCurrentTerm)
Once registered, you should be able to call the function in your queries:
def a = SaturnStvterm.findAll("from SaturnStvterm as s where id > TT_STUDENT.STU_GENERAL.F_Get_Current_term()")
I have a simple unit test where I execute the same NHibernate named query 2 times (different session each time) with the identical parameter. It's a simple int parameter, and since my query is a named query I assume these 2 calls are identical and the results should be cached.
In fact, I can see in my log that the results ARE being cached, but with different keys. So, my 2nd query results are never found in cache.
here's a snip from my log (note how the keys are different):
(first query)
DEBUG NHibernate.Caches.SysCache2.SysCacheRegion [(null)] <(null)> -
adding new data: key= [snipped]... parameters: ['809']; named
parameters: {}#743460424 &
value=System.Collections.Generic.List`1[System.Object]
(second query)
DEBUG NHibernate.Caches.SysCache2.SysCacheRegion [(null)] <(null)> -
adding new data: key=[snipped]... parameters: ['809']; named
parameters: {}#704749285 &
value=System.Collections.Generic.List`1[System.Object]
I have NHibernate set up to use the query cache. And I have these queries set to cacheable=true. Don't know where else to look. Anyone have any suggestions?
Thanks

Okay - i figured this out. I was executing my named query using the following syntax:
IQuery q = session.GetNamedQuery("MyQuery")
.SetResultTransformer(Transformers.AliasToBean(typeof(MyDTO)))
.SetCacheable(true)
.SetCacheRegion("MyCacheRegion");
( which, I might add, is EXACTLY how the NHibernate docs tell you how to do it.. but I digress ;) )
If you use create a new AliasToBean Transformer for every query, then each query object (which is the key to the cache) will be unique and you will never get a cache hit. So, in short, if you do it like the nhib docs say then caching wont work.
Instead, create your transformer one time in a static member var and then use that for your query, and caching will work - like this:
private static IResultTransformer myTransformer = Transformers.AliasToBean(typeof(MyDTO))
...
IQuery q = session.GetNamedQuery("MyQuery")
.SetResultTransformer(myTransformer)
.SetCacheable(true)
.SetCacheRegion("MyCacheRegion");
