Why this less specification fails to apply the background to the div?


Why this less specification fails to apply the background to the div?

I hope this helps . My goal is to set the background of the div of class notice-bar to red when the page is loaded in an iphone or similar mobile device. , Your LESS/CSS works, you just have the wrong selector.
code :
.active .content .notice-bar{}
.active.content{} /* notice there is no space bewteen active and content*/
.content .active .notice-bar{
  background: red;
}

.content.active .notice-bar{
  background: blue;
}
<div class="content">
  <div class="active">
    <div class="notice-bar">
      .active is the child of .content
    </div>
  </div>
</div>

<div class="content active">
  <div class="notice-bar">
      parent has two classes
  </div>
</div>

Hope this helps Are you sure your SQL query returns what you would like? Numeric(0) suggest that you retrieve an empty resultset. Furthermore, as pointed by @Prasad Chalasani, try to post a more precise problem description. From the above I am not sure I understand what your aim is.
Creating copy of database - Fails due to use of 'Identity' specification

Creating copy of database - Fails due to use of 'Identity' specification

I hope this helps you . I actually figured it out. I already knew that there must be a way to temporarily disable the identity specification, but the solution was a little different. Instead of 'disabling' and 're-enabling' the identity specification, there's another command (as in a comment above) called IDENTITY_INSERT which when switched on, it allows inserting values to an identity field - and you need to ensure it gets switched back off too. The IDENTITY_INSERT switch is per-connection-session, so it does not affect other sessions. As long as IDENTITY_INSERT is on, you can insert records with a specific value for that identity field - so long as it's still within the primary key constraints.
The actual solution was NOT to write a script with SET IDENTITY_INSERT MyTableName ON, but rather in the database export utility (in SQL management studio), when selecting the tables, select all the tables and choose the advanced setting to use IDENTITY_INSERT.

Does that help This occurs commonly with flex as it is picky about recognising lines. You will have missed the end-of-line symbol before the end-of-file.
Using your text editor to append a line to the end of file will resolve your error.

seems to work fine I am not a Spring or Java EE user, but I can help you with the aspect part. I googled a bit, too, because your code snippets without imports and package names are a bit incoherent, so I cannot just copy, paste and run them. Judging from the JavaDocs for JpaRepository and JpaSpecificationExecutor, both of which you extend in your ExampleRepository, you are trying to intercept
code :
Page<T> PagingAndSortingRepository.findAll(Pageable pageable)
List<T> JpaSpecificationExecutor.findAll(Specification<T> spec, Pageable pageable)
@Around("execution(* findAll(*)) && args(pageable) && target(exampleRepository)")
public Object filterQueriesByCompany(ProceedingJoinPoint thisJoinPoint, Pageable pageable, ExampleRepository exampleRepository) throws Throwable {
  return exampleRepository.findAll(CompanySpecification.fromCompany(user), pageable);
}
@Around(
  "execution(* findAll(*)) && " +
  "args(pageable) && " + 
  "target(jpaRepository) && " +
  //"within(org.springframework.data.jpa.repository.JpaRepository+) && " +
  "within(org.springframework.data.jpa.repository.JpaSpecificationExecutor+)"
)
public Object filterQueriesByCompany(ProceedingJoinPoint thisJoinPoint, Pageable pageable, JpaRepository jpaRepository) throws Throwable {
  return ((JpaSpecificationExecutor) jpaRepository)
    .findAll(CompanySpecification.fromCompany(user), pageable);
}
@Around(
  "target(jpaSpecificationExecutor) && " +
  "execution(* findAll(*)) && " +
  "args(pageable) && " + 
  "within(org.springframework.data.jpa.repository.JpaRepository+)"
)
public Object filterQueriesByCompany(ProceedingJoinPoint thisJoinPoint, Pageable pageable, JpaSpecificationExecutor jpaSpecificationExecutor) throws Throwable {
  return jpaSpecificationExecutor.findAll(CompanySpecification.fromCompany(user), pageable);
}
@Around(
  "target(jpaSpecificationExecutor) && " +
  "execution(* org.springframework.data.jpa.repository.JpaRepository+.findAll(*)) && " +
  "args(pageable)" 
)
public Object filterQueriesByCompany(ProceedingJoinPoint thisJoinPoint, Pageable pageable, JpaSpecificationExecutor jpaSpecificationExecutor) throws Throwable {
  return jpaSpecificationExecutor.findAll(CompanySpecification.fromCompany(user), pageable);
}
@Around("target(jpaSpecificationExecutor) && execution(* findAll(*)) && args(pageable)")
public Object filterQueriesByCompany(ProceedingJoinPoint thisJoinPoint, Pageable pageable, JpaSpecificationExecutor jpaSpecificationExecutor) throws Throwable {
  return jpaSpecificationExecutor.findAll(CompanySpecification.fromCompany(user), pageable);
}

Any of those help You want to achieve something like ternary operator which is hard to get but possible:
code :
[
   {
      "operation":"shift",
      "spec":{
         "PersonName":{
            "*":"&"
         }
      }
   },
   {
      "operation":"modify-overwrite-beta",
      "spec":{
         "ID":[
            "=toInteger",
            "Floating"
         ]
      }
   },
   {
      "operation":"shift",
      "spec":{
         "ID":{
            "@":"ID",
            "Floating":null,
            "*":{
               "#Fixed":"ID"
            }
         },
         "*":"&"
      }
   },
   {
      "operation":"modify-overwrite-beta",
      "spec":{
         "ID":"=lastElement(@(1,ID))"
      }
   },
   {
      "operation":"shift",
      "spec":{
         "FirstName":{
            "*-*-*":{
               "$(0,3)":"Birth.YearOfBirth"
            }
         },
         "LastName":"Employee.LastName",
         "ID":"Element.Category"
      }
   }
]
