I have a page where I have implemented an af:query and a result table. The problem is that I can't retrieve within a managed bean method the exact query that is used at runtime by this component.
Is there any way to get the query string that is being executed within the af:query component?
Thanks
I found the answer here https://community.oracle.com/thread/3516102 I have to override the executeQueryForCollection(), and, before super call, I can print out the result of getQuery() method.
The detailed solution is explained here: Get SQL Query and Parameters from af:search

I am trying to write some basic MongoDB custom queries in Kotlin.
I've seen nearly everywhere that people use a method addCriteria:
val query: Query = Query()
query.addCriteria(Criteria.where("field1").exists(true)))
But it seems there is no method addCriteria in Query which I use: org.springframework.data.mongodb.repository.Query
I am very confused. Cannot find any explanations on how to write custom MongoDB queries in Kotlin with Spring Data except using this method.
So, I was very close to the problem's solution. I really used wrong Query, despite it's path looks really logical. I needed this one: org.springframework.data.mongodb.core.query.Query.
I used org.springframework.data.mongodb.repository.Query, which is Query annotation, not the class
I know how to call specific scenario from another feature file and pass parameters along. But is there a way I can do it while checking for condition using 'if'?
For instance:
* if (role=="SME"||role=="BA") karate.call('classpath:rough/utility.feature#checkDisabled'){element: #(elem)}
If this is the wrong implementation as what I get from the console. Please suggest me a way how can i achieve this in karate?
Thanks
When you use karate.call() put the second argument inside the round brackets. This is pure JS and "Karate-style" embedded expressions will not work.
* if (role=="SME"||role=="BA") karate.call('classpath:rough/utility.feature#checkDisabled', {element: elem})
Please take some time to read this part of the docs: https://github.com/karatelabs/karate#call-vs-read
What is actual use of dbms_assert.noop ?
Since this function performs no error checking and returns the input string as it was entered.
Read here on Pete Finnigan's blog where he discusses the dbms_assert.noop function. it mentions:
This (dbms_assery.noop), we can now clarify is used to mark a piece of code that is not to be tested by automated test tools (presumably Fortify) as this function does nothing except return the string passed unchanged.
By this, what I have understood that I can use this function where I am passing actual piece of code through a variable and I don't want it to be checked for SQL injection attacks.
This is one of the many uses of this function.
I've a simple class like this:
Public Class CalculationParameter{
public Long TariffId{get;set;}
}
In a workflow activity, I've an Assign like this:
(From tariffDetail In db.Context.TariffDetails
Where tariffDetial.TariffId = calculationParameter.TariffId).FirstOrDefault()
Dto is passed to Activity as an Input Argument.
It raise following error and I'm wondering how to assign Id. Any Idea?
LINQ to Entities does not recognize the method 'Int64
GetValue[Int64](System.Activities.LocationReference)' method, and this
method cannot be translated into a store expression.
How can I assign the calculationParameter.TariffId to tariffDetial.TariffId?!
UPDATE:
Screen shot attached shows that how I'm trying to assign calculationParameter.TariffId to tariffDetail.TariffId (car.Id = Dto.Id) and the query result should assign to CurrentTrafficDetail object.
Here's your problem. I don't know if there is a solution to it.
As you said in a (now deleted, unfortunately necessitating that I answer) comment, the exception you're getting is
LINQ to Entities does not recognize the method Int64 GetValue[Int64](System.Activities.LocationReference) method, and this method cannot be translated into a store expression.
in your Linq query, calculationParameter is a Variable defined on the workflow. That Variable is actually an instance that extends the type System.Activities.LocationReference and NOT CalculationParameter.
Normally, when the workflow executes, the LocationReference holds all the information it needs to find the value which is assigned to it. That value isn't retrieved until the last possible moment. At runtime, the process of retrieval (getting the executing context, getting the value, converting it to the expected type) is managed by the workflow.
However, when you introduce Linq into the mix, we have the issue you are experiencing. As you may or may not know, your expression gets compiled into the extension method version of the same.
(From tariffDetail In db.Context.TariffDetails
Where tariffDetial.TariffId = calculationParameter.TariffId)
.FirstOrDefault()
is compiled to
db.Context.TariffDetails
.Where(x => x.TariffId = calculationParameter.TariffId)
.FirstOrDefault();
When this executes, L2E doesn't actually execute this code. It gets interpreted and converted into a SQL query which is executed against the database.
As the interpreter isn't omniscient, there are a well defined set of limitations on what methods you can use in a L2S query.
Unfortunately for you, getting the current value of a LocationReference is not one of them.
TL:DR You cannot do this.
As for workarounds, the only thing I think you can do is create a series of extension methods on your data context type or add methods to your CalculationParameter class that you can call from within the Expression Editor. You can create your Linq to Entities queries within these methods, as all types will already have been dereferenced by the workflow runtime, which means you won't have to worry about the L2E interpreter choking on LocationReferences.
*Edit: A workaround can be found here (thanks to Slauma who mentioned this in a comment on the question)
I've seen this opportunity reported at least half a dozen times with about as many responses.
My problem is, I've got a MySQL database function defined, we'll call it "my_func(int val) returns int", which works fine if I test directly on the database.
I've also gotten it to work with a direct SQL passthrough my repository implementation, which is okay, but I'd rather route it through Hql, for some god-awful reason...
So... I've got a MySQL5Dialect setup to register the function and I'm having some difficulty parsing through the expected conventions.
My understanding is that I need to prefix the function name with "dbo." at some point during the function registration?
Something like this,
//...
RegisterFunction("my_func", new SQLFunctionTemplate(NHibernateUtil.Int32, "my_func(?1)"));
//...
And then through my repository,
var value = repository.FindByHQL<int>("select my_func(2)").Single();
Where FindByHQL returns an IList.
Any thoughts why this wouldn't work.
I'm running the latest WAMP (2.1e I think).
Enough info? Let me know if I can provide any further details.
Thanks,
Michael
select my_func(2)
is not valid HQL, regardless of whether the function is registered or not.
You can use SQL instead if that's your use case.
Post full exception with stack trace if it's not and this was just a simplified example.
