parameterized

问题 Can the MySQL Query Browser set parameters of a parameterized query? If so, how? I tried populating the Parameter Browser tab but it doesn't seem to actually set parameters when I execute the query. I searched for quite a while in Google (e.g. mySQL Query Browser parameterized) but had no luck finding the answer. I found this thread on the mySQL forums-- sounds like I'm not the only one scratching my head here. I'm using Version 5.1 on Windows Server 2008 (client and server), if that matters.

问题 I have two sets of data: [t1 ; x] and [t2 ; y] , where the t s are in the same range for both, but possibly taking different values. A simple example: [t1 ; x] = 1 2 4 1 4 16 [t2 ; y] = 1 3 5 1 9 25 Here the underlying functions are simple: x = t1.^2 and y = t2.^2 . My goal is to get a plot of x versus y . Since the values taken by t aren't the same, I cannot simply use plot(x,y) . For the example, since x == y , I should get a line of slope 1 , but plot(x,y) isn't straight and neither piece

问题 I have a strange problem with inheritance and I don't understand why it should not work: public interface A { } public interface B extends A {} public class C { void test() { ArrayList<A> foo = new ArrayList<B>(); } } But compiling gives me the following error Type mismatch: cannot convert from ArrayList<B> to ArrayList<A> C.java /bla/src/de/plai/test line 8 Java Problem 回答1: ArrayList<? extends A> foo = new ArrayList<B>(); A List of A is not the same that a List of B because you could not

问题 I know: this has been done to death. But, believe me, I've been researching for quite a while on how to fix this one. What I'm trying to achieve is a PDO MySQL Database wrapper for use with PDO that I can just incorporate into my code. My main problem stems from two functions in particular, as well as the actual binding of the parameters I'm trying to reach. The reason why I state two functions as opposed to one is, despite my efforts, I haven't been able to spot which one is attempting the

问题 I am quite new to Java ... I wrote a class called DLPFile which is basically a container of other objects like Strings, ints, floats, etc. When putting my files into a List and then saving it in my session (which is from Map class) variable is easy; DLPFile file = new DLPFile(); List <DLPFile >fileList = new ArrayList <DLPFile>(); fileList.add(file); session.put("filesList", fileList); but how do I retrieve the list from the session var? When I do: List <DLPFile files = (List) session.get(

问题 There is a nice possibility to run JUnit test with parameters where the same test method is executed multiple times with different data as described here: http://junit.org/apidocs/org/junit/runners/Parameterized.html Unfortunately, it only seems possible to use primitive parameters or Strings, but not objects. Is there any workaround known for this? 回答1: The type of the data() method in the use of the @Parameters annotation is List<Object[]> , so you can put in any object. To pass in, e.g., a

问题 I have a BaseTest class which consists of several tests. Each test shall be executed for EVERY profile I list. I thought about using Parameterized values such as: @RunWith(Parameterized.class) @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) // @ActiveProfiles("h2-test") // <-- how to iterate over this? public abstract class BaseTest { @Autowired private TestRepository test; // to be used with Parameterized/Spring private TestContextManager testContextManager;

问题 I want to make an adjustment to a cell in excel without opening the application for it. I want to do this with Jenkins so i can automate (regression)tests. (Is this even possible??) As you can see in the image I attached, I wat to change a “N” value in excel to an “Y” value, or vice versa. I want to achieve this trough the UI of Jenkins. I’ve heard something like a parametrized build, but I can’t get my hands on any website or something that can tell me more about this subject. What I want to

问题 Can Apache Avro handle parameterized types during serialization? I see this exception thrown from Avro framework when I try to serialize an instance that uses generics - org.apache.avro.AvroTypeException: Unknown type: T at org.apache.avro.specific.SpecificData.createSchema(SpecificData.java:255) at org.apache.avro.reflect.ReflectData.createSchema(ReflectData.java:514) at org.apache.avro.reflect.ReflectData.createFieldSchema(ReflectData.java:593) at org.apache.avro.reflect.ReflectData

问题 I am new to parameterized feature of JUnit 4.x and having a problem. My parameterized test consists of 3 integer arrays and I am having difficulty of how to declare them.
